New product development should be the vital component for product policy and management for those, who want to continue to exist in today’s competitive world. It is the time of need, to launch new products timely because of changing demands and the customer needs to follow new trends, which are prevailing in the society. The key to success and sustainability is the company’s innovative approach towards new product development.

New product development is not an easy process. Most of the companies use a structured and well-highly organized approach for new product development. It needs an incredible amount of time and research. First off, the idea is generated based on the needs of the customers. The idea then gets transformed into concept, then it is tested to evaluate the characteristics of the product along with feasibility, target market and production cost. After this sale, the most important step is based on the customers’ feedback. Customer needs are more important than the quality of the product. After this step, profitability evaluation is done and then prototype of the product is made. It is then market tested and changes are made accordingly.

Now after this process, this prototype is converted to benchmark for an end product and production gets started based on the final study of logistics, operations and resource needs etc. Marketing activities, advertisement, promotions etc are the next step to promote the sale of the final product. Research is the key element in the new product development process.

The use of plastic bottles expanded over time and now they are used in health, beauty aids and food containers along with household products for safer, lighter and easy to handle features. Plastic bottle designs are versatile. Before deciding about the plastic bottle design, there are many things to consider such as product end user, bottle hold, options of molding and filling, and other packing considerations. Innovative and attractive, plastic bottle design help in the promotion of products.

Along with good plastic bottle design, structural branding design is also essential to give the product memorable brand identity.

Branding is a perception, when money is spent on building the perception of the individual, for that particular brand it is called strengthening the brand. Structural Branding Design is also important to make the brand strong enough to impact the individual’s purchase behavior, which is called brand trust.

Designers do Structural Branding Design to strengthen brands and generate the shortcuts between brand essentials and individuals’ perceptions. Structural branding design helps create designs that focus on making certain that users accomplish goals, which have long term effect on brand strength. Successful companies earning high profits, spend a lot on structural branding design to strengthen brand perception.

In the rapidly paced community of plastic molding, injection mildew design and style is one of the most intriguing and difficult work to be observed. You will draw upon all of your innovative skills as you acquire the layout for new products.

It may possibly glance quick mainly because of the highly effective CAD applications, but in fact, they are just tools to enable you. In the discipline of injection mold style you normally will need to produce new and first methods of plastic molding. This occasionally involves a good deal of creativeness and inventiveness. What is a regular day like for injection mildew pattern? Most injection mold designers comply with a timetable similar to the mold makers. Since their mildew styles are shortly heading to be manufactured by the mold makers, there is a extremely near connection involving these two.

A mold designer spends most of his time at his laptop or computer, working with highly effective CAD systems these as Unigraphics, AutoCAd, SolidWorks, MasterCam and quite a few, numerous other people. Presently, the programs are extremely rapid and potent.

Incredibly frequently the mildew designer will be required to talk with the several mildew makers, CNC programmers, WEDM operators, etc.. This rapport is important for a successful vocation as an injection mold designer.

Usually the designer does not work very as a lot of several hours per week as the mold maker. Frequently mildew designers have a store background and assist out in the mildew doing shop as effectively. This is particularly popular if there is a slowdown in style and design and a ton of do the job in the store. How do you turn into an injection mildew designer? Effectively, there are two paths in the USA. 1 is to master on the position and the other is to learn at a style and design university. Equally are typical and do the job nicely.

Numerous plastic molding designers arrive from a mildew making history. This is in particular helpful to offer a practical solution to mildew layout. There is no substitute for practical expertise!

Many tech schools and universities supply excellent programs on plastic injection mildew design. A history in mechanics, spatial relationships, power to visualize 3D sections, and mathematics are all essential.

Is there a future in injection mold design?

Like every little thing else linked with the plastics market, the reply is of course and no. Of course, since the plastics area is increasing all the time and skilled designers are in great demand and lower supply.

No, simply because the subject is so aggressive on a world-wide scale. In this electronic age the designer does not even need to be in the same country as the mold maker. I had this practical knowledge at a person store the designer was in Canada and we have been in the USA. It worked very well, but required considerable telephone time on the part of the task manager. Conclusion Doing work in injection mold style is challenging, intriguing, secure, well having to pay and in need. Anybody interested will obtain quite a few great programs out there and companies trying to find qualified designers.

The concept of 3D printing has been in existence for more than a decade and yet its usage is still not that popular outside the fields of engineering, architecture and manufacturing. The fact that this concept is slowly creeping into the world of art, medicine and education in recent years does not answer the basic question of when 3D printing will be available to the ordinary household consumer.

That day may come sooner than we think. Certainly most industrial-grade 3D printers are still too expensive at around ,000 a pop to be brought into ordinary households. Homemade 3D printers created using open source plans downloaded from fabber websites may be a lot cheaper and exciting to build for geeks, but the layman will have trouble building them.

What then is the solution? A company called Idealab came up with a cheaper alternative to industrial-grade 3D printers that do not require DIY stunts which is the only way a fabber would work. This alternative is called the Desktop Factory.

What Is the Desktop Factory?

The Desktop Factory is a 3D printer that you can put right on your desktop. At 25 x 20 x 20 inches, it is rather bigger than your ordinary desktop inkjet printer, but you definitely would not need an extra table for it unless you really have to. It is also quite a heavy gadget, weighing approximately 90 lbs.

Just like with 3D printers made with fabbing, you can make almost anything with the Desktop Factory as long as the raw materials you need are just plastic. Right now, plastic is the only raw material that the Desktop Factory can work with. The parts you can make with this 3D printing machine can have a maximum dimension of 5 x 5 x 5 inches, but this does not mean that you cannot glue these parts together to build a larger scale model later on.

The Potential of 3D Printing at Home

The idea of being able to print 3D objects of your own at home opens a lot of wonderful possibilities. Remember that you can make almost anything with a 3D printer. For instance, you can spoil your child by making the toys that he or she wants straight out of your printer. You can design and make your own plastic dinnerware that you can use on picnics and backyard barbecues. You can make your own plastic fashion accessories. If you are into arts and crafts, having the components of your project made using a 3D printer can save you a trip to the craft supplies store.

There are just so many possibilities that the idea of being able to create 3D objects using a desktop printer can open. Of course you may wonder about the cost of having such a 3D printer like the Desktop Factory around. Right now, the Desktop Factory is priced at a little less than ,000. It is still a bit too expensive for most householders, but this price tag certainly brings 3D printing closer to home.

The standard process steps can be identified as clamping, heating with sheet level activated, pre-stretch, forming with plug aid, cooling with air and spray mist, release and trimming they’re examined more closely under the following sub headings ;

Clamping
The clamp frame should be satisfactorily dynamic enough to guarantee the plastic sheet is firmly held in the forming process. It should be in a position to handle the thickest material certain to be formed on the machine up to 6mm with a single heater model and up to 1Omm with the twin heater machines. If an automatic process is employed the operation of the moving parts must be guarded and interlocked to avoid random damage.

Heating
Heaters are usually infra-red elements mounted inside an aluminium reflector plate. In order to obtain the best vacuum forming results, using any material, it is important that the sheet is heated regularly over its entire surface area and throughout its thickness. So as to achieve this it is necessary to have a sequence of sections which are managed by energy regulators. Ceramics do have some d rawback in that their high thermal mass makes them slow to warm up ( approx fifteen mins ) and slow in their reply time when adjustments are made.

Sheet Level
A photo-electric beam is incorporated in the machine to scan between the bottom heater and the sheet of plastic. If the sheet of plastic sags down and breaks the beam then a small amount of air is injected into the bottom chamber, so lifting the sheet to prevent it from sagg ing.

Pre-stretch ( Bubble )
Once the plastic has reached it’s forming temperature or “plastic” state it can be pre- stretched to ensure even wall thickness when the vacuum is applied. Pre-stretch is an invaluable feature when forming deep draw parts with minimum draft angles and high mold surface detail. The technique of controlling the bubble height should be such that consistent results are obtainable.

Vacuum
Once the material is suitably pre-stretched a vacuum can be applied to assist in forming the sheet. With larger machines a vacuum reservoir is used in conjunction with a high volume capacity vacuum pump. This enables a two stage vacuum to be applied making certain quick moulding of the heated sheet.

Plug aid
Plug-assist forming is the term used to describe the use of a male plug tool, mounted on a pneumatic or hydraulic cylinder situated over the forming area of the machine, to force the material into a female cavity within the moulding area. It enables complex and deep-draw moulds to be produced without webbing and with even thickness distribution. The idea behind the process is to feed as much material into the hole prior to the vacuum being applied to avoid thinning in that area. Plug moulds are typically made of wood or metal and a smooth surface permits the sheet to slip whilst stretching into the mould. A felt or leather lining guarantees that the danger of premature chilling on contact is seriously reduced. Resin plugs supply a reasonable alternative as being good insulators they don’t affect the temperature of the sheet.

Plug assist is also an essential feature when forming multiple impression male moulds as they can be placed awfully close together without the fear of the material webbing between the formed parts.

Cooling and Release
Once formed the plastic must be permitted to cool down then was released. If released too soon then deformation of the moulding will end up in a reject part. To hurry up the cooling cycle high speed fans are fitted and turned on once the part is created. A spray mist option is available whereby nozzles are attached to the fans and a fine mist of chilled water is directed onto the sheet. This, together with the fans can improve the cooling cycle by almost 30%.

Mildew temperature control units are also available which control the temperature in the mould ensuring accurate and consistent cooling instances when cooling crystal-like and crystallising polymers like PP, HDPE and PET.

Once cooled adequately the sheet can be released by a reverse pressure activated through the vacuum system. The part is then stripped from the mould and moved to the trimming station.

Trimming and Finishing
In vacuum forming once the formed part has cooled and been removed from the machine the surplus material is removed. Holes, slots and cut-outs are then drilled into the part. Other post-forming processes include decoration, printing, bracing, reinforcing and assembly.

I saw this guy, Richard Jacobsen, demonstrate how to make a vacu-form mold using parts in total that all costs less than 0. He was a super nice guy, and his demonstration was perfectly clear. All you need is a heat source, plywood frames to hold the styrene (plastic), a rubber mat with a hole in it, and a shop vac. It worked brilliantly.

Design is a matter of balance between weight and strength, cost and quality, speed and accuracy. Prototyping is an important part of the designing process and presents the designer with multiple choices.

In plastic product design, technology has provided various prototyping options.

Rapid prototyping (RP) involves  stereolithography, selective laser sintering, fused deposition modeling, laminated object manufacturing, and three dimensional printing.  These processes build parts, one-by-one, from 3D-CAD models, joining layers of material to create the finished prototype.

Rapid tooling (RT) uses rapid prototyping to create the initial part and then creates, from that part, a mold in which additional parts can be made.

Another prototyping option is rapid injection molding (RIM), which works directly from a 3D-CAD model, using CNC mechanism to crush aluminum molds in which true injection-molded parts can be made.  Finally, there is conventional injection molding, which is used primarily for production, but can also be used to create prototypes.

Liquid injection molding is commonly known as the technique for producing a wide range of product from different materials. Two of the most commonly used materials are plastic and liquid silicone. Both of them have good flexibility which is beneficial for the ease of the production. To industrial setting, this process is very beneficial since it allows them to create a lot of identical parts in a short time.

The plastic which is used for this process is firstly melted before it is molded. The melted plastic can be easily formed into the desired shape. On the other hand, if the silicone is used, it will be cured through chemical process by combining the base of the rubber with the catalyst. This process can be done outside the mold before or during the injecting process.

This silicone or plastic is injected to the closed and locked mold by using the plunger syringes. In this mold, the plastic will be cooled. On the other hand, the silicone will be cured when the process of chemical runs the course. In addition, if the silicone is not previously catalyzed, it will be added using the rubber base as well as the catalyst. Simply inject the catalyst and rubber base to the mold using two separate plungers. If all the parts have been cooled and cured, they will be ejected out of the mold.

To perform the process of liquid injection molding, you will need special machinery. That machinery used is very complex with some different standard parts including supply drum which is to handle the raw materials such as silicone, plastic, and pigment till they are ready to be employed. Another part is metering units which are to pump the some different liquid components into the mixer in the premeasured proportions so that all the raw materials can blend into one. Another part is injector which is to force the casting material into the mold by using pressurized force.

All of this material started out generally as plastic pellets. The pellets are feed into one of the huge molding machines, these machines often weigh around twenty-five tons. The machine heats the plastic till it is liquid. This liquid is then forced thru injectors into molds.

These molds can be made to almost any shape or size. To put it simply, injection molding is the process of causing liquified plastic in to a mold hole. Once the plastic has cooled, the part can be ejected. It is useful when the parts are too complicated or cost prohibitive to machine. With this process, many parts can be made at the same time, out of the same mold.

The method has usually 6 steps :

1. Clamping : the machine has 3 parts. The mold, the clamp and the injection unit. The clamping unit holds the mold at a certain pressure, this ensure uniformity in the units that are outputted. Molds are usually made of two parts.

2. Injection Unit : this is where the plastic pellets are loaded into a hopper at the top of the injection unit. The pellets are fed into the main cylinder ; this is where they are heated until they are liquefied. Within the injection unit there is a screw which turns and mixes the plastic. Once this liquid plastic has reached the ideal for this product the injection process starts. The plastic is forced thru a sprue and the pressure and speed are under the control of the screw or sometimes a ram depending on the sort of machine.

3. Dwelling : this is a pause in the process while some pressure is applied to ensure all the mold cavities have been completely filled. This is vital within the process as it will end up in scrap of units if the mold isn’t filled in the right way.

4. Cooling : this part of the process lets the mold cool for the necessary period. If it is done too quickly the units can stick or become misshapen once out of the machine.

5. Mold Opens : The clamping unit is opened to separate the mold. Molds are used over and over again ; they are often the most vital single part in the whole process. The tooling of mold can be extremely costly.

6. Ejection : the finished product is ejected from the injection mold machine. Frequently the finished product will continue on a production line or be stacked to go to a production line as parts for larger products, e.g. Car wheel.

The products that use injection molding are used every day by all of us. Many vehicles wouldn’t be so affordable if it wasn’t for injection molding, however there are some downsides to the method. The machinery is very expensive and involves a high capital investment, design of parts must bear in mind the production process, and the process isn’t economically for short runs of products.

However the downside are out-weighed by the larger benefits, The speed at which parts can be made, low labor costs, minimal material waste, and finished parts frequently need no more finishing.

Mold is a major technical equipment of modern industry, the production of many industrial products, an indispensable component. China’s accession to WTO, ability to attract foreign investment increased year by year, the status of the world become more prominent product manufacturing plants, various industrial products import more and more mold.

    The type of mold is usually processed in accordance with the different objects and processes are classified, from the industry point of view the main distinction between a plastic mold, rubber mold, the metal of the cold die, Metal extrusion die of cold and hot extrusion dies, metal drawing die , powder metallurgy molds, metal casting molds, metal casting molds, glass molds, fiberglass mold and so on.

    The following only in respect of imports of the most common plastic molding process used in the different types of mold are classified and how to make a description.

    The most common method of plastic forming the melt into the general shape and solid forming two main categories: the melt molding is the plastic heating to above the melting point, so that at the molten state for molding the way, is such a molding method of molding process mainly injection molding, compression molding (reduced) molding, extrusion, etc.; solid phase forming is less plastic in the melting temperature to maintain a class under solid molding method, such as the production of some plastic containers vacuum molding, compressed air forming and blow molding. There are also liquid molding methods, such as casting plastic molding, slush and dip dip molding method.

    The molding method according to the different, different processes can be divided into the corresponding requirements of plastic processing mold types, mainly injection mold, extrusion mold, pressure mold plastic, blow mold, plastic mold, high foam polystyrene Ethylene forming molds.

    Injection (plastic) molds

    It is mainly the production of thermoplastic items most widely used as a mold, plastic injection mold corresponding to the processing equipment is plastic injection molding machine, plastic injection machine at the end of the first heating the barrel to heat melting, then the injection machine screw or a plunger, driven by the injection machine nozzle and mold pouring into the mold cavity systems, cooling hardening plastic molding, mold release by products. Usually forming part of its structure, gating system, oriented components, introduced institutions, thermostat systems, exhaust systems, components and other supporting components. Manufacturing materials, usually plastic mold steel module, the material used mainly for carbon steel, carbon tool steel, alloy tool steel, high speed steel. Injection molding processing methods usually apply only to the production of thermoplastic varieties of products, manufactured using injection molding process a wide range of plastic products, from daily life to all kinds of complex mechanical, electrical, transport and other parts are injection molding, and Production of plastic products it is the most widely used as a processing method.

    Plastic compression molds

    Including compression molding and injection compression molding die two structure types. They are mainly used to shape a class of thermosetting plastic mold, its corresponding equipment is pressure molding machine. Compression molding method is based plastic features, will mold heated to molding temperature (usually in the 103 -180 ), and then measure a good plastic powder into the mold cavity pressure and the feeding room, closed mold, plastic at high temperature, high pressure tends to soften the viscous flow, after a certain time after the curing stereotypes, as the shape of the required products. Pressure injection molding and compression molding is different with a separate feeding room, before forming the first closed mold, plastic, finished in warm indoor feeding was viscous flow state, under pressure and speed to squeeze into the mold cavity, curing molding. Compression mold is also used to shape some of the special hard to melt thermoplastics such as thermoplastic (such as PTFE) rough (cold forming), the optical properties of high resin lens, slightly foaming nitrocellulose car steering wheels . Compression molds mainly by the cavity, feeding cavity, oriented institutions, introduction of components, heating systems and other components. Pressure injection molds are widely used in packaging electrical components area. Manufacture of compression molds and injection molds used in the same material.

    Plastic Extrusion Tooling

    Is used to produce a continuous shape forming a kind of plastic products mold, also known as extrusion head, is widely used in pipes, rods, filaments, sheets, film, wire and cable coating, profiles and other processing. Their corresponding production equipment is plastic extrusion machine, the principle is solid plastic in the heating and rotating screw extruder melt under high pressure, plastics, die by a specific shape made of the same shape of cross sections and die continuous plastic products. The main material of carbon steel, alloy tool steel, and some out of the mold parts will need to wear a wear-resistant materials such as diamond inlay. Extrusion processing technology normally only used in the production thermoplastic varieties of products, its structure and injection molds and pressure modeling has obvious difference.

    Plastic Blow Mold

    Is used to molding hollow plastic container class products (such as beverage bottles, cosmetic packaging supplies and other containers) of a mold, blow molding process principle in the form mainly by extrusion blow molding, injection blow molding hollow , injection blow molding extension (commonly known as “injection stretch blow”), multi-layer blow molding, sheet molding, blow molding hollow. Hollow blow molding products corresponding to the device commonly known as plastic blow molding machine, blow molding is only applicable to the production of thermoplastic varieties of products. Blow mold structure is more simple, more than the materials used to manufacture carbon steel.

    Plastic Forming Mold

    Is a plastic plate, sheet material as raw material, some of the more simple plastic molding a mold, the principle is the use of vacuum or compressed air forming method of forming methods to fix the die or punch on the plastic plates, sheets, in case of heating to soften the deformation of the mold cavity attached to get the required shape products, mainly for some daily necessities, food, toys packaging products production. Plastic mold for low pressure molding, the die cast aluminum or non-metallic materials and more materials used, the structure is relatively simple.

    High foam polystyrene mold

    Is the application of expandable polystyrene (made of polystyrene and foam particles composed of bead-like) all the necessary raw materials for forming the shape of a mold foam packaging materials. The principle is that polystyrene can be made by blowing steam into the mold shape, including simple manual hydraulic press mold and mold are two types of straight-foam is mainly used to produce industrial products packaging products. Manufacture of such materials are cast aluminum molds, stainless steel, bronze, etc..
