A new development method may allow breaking away from the pack as rapid prototype Shenzhen companies continue to employ outsource facilities that offer flexibility and foster innovation.

Innovation, whether through the development of new products or processes, has become crucial for companies in virtually every industry. New technology holds the key to competitive advantage and, perhaps, survival.

For manufacturers, the problem is particularly acute because of the ease with which competitors can outsource production. No longer can mature companies, with established manufacturing bases, count on an economy-of-scale advantage as a barrier to entry from new competitors.

Pressure longxiang-ltd.com has worked with hundreds of customers from the large multi-national corporations to small entrepreneurial start-ups, applying unique configurations of equipment and extensive chemical expertise. These efforts have often resulted in new products, processes and, at times, new business segments for the client company. As expected of developmental projects, however, many failed to produce a successful innovation, though, in retrospect, a large number of the attempts did yield substantial savings for the sponsoring client. Early “failures” have prevented a company from making large investments in a process that wouldn’t work as anticipated or in a product that couldn’t meet the performance and economic needs of the marketplace.

“We’ve been able to observe scores of successes, near misses, and failures — the entire range of potential results,” says Larry Rosen, CEO of Pressure Chemical. “In an effort to improve our own internal processes, we began to examine the data closely and realized that we had learned to do things in a new and different way, having seen the best and the worst of all the organizational processes used by our customers.” With the help of an outside consultant, Droz and Associates, we cataloged our new products and processes that illustrated a variety of circumstances, parameters and goals. The consultant found that our method was a radical departure from traditional budget-driven, stage-gate approaches.

Although attempts have been made to improve the traditional method, such as the CPM (Critical Path Method), a joint venture between DuPont and the Remington Rand Corp., the approach was flawed. The Japanese, perhaps driven by their respect for W. Edwards Deming, evolved a step-gate method that looks back periodically to correct the trajectory of a project. Still, something was lacking.

Droz helped us to conceptualize the approach in a graphic manner that illustrates the central distinction of this cyclic route from the traditional straight-line approach. The key benefits of this novel approach, which we call Concept to Commercialization (rapid prototype), are reduction in time, cost and risk, akin to a hat trick in hockey, according to Rosen.

The goal of a recent project, undertaken for a major international manufacturer, was the hydrogenation of a polymer for use in high-capacity data storage. This client chose to outsource the project because of the diversity of appropriately sized equipment available in our facility. The base polymer had been produced by the client in its large continuous production facility and the scope of work was limited to hydrogenation. Unfortunately, market testing of the target product revealed that its properties failed to meet expectations. Because it wasn’t feasible to interrupt commercial production to produce small quantities of differentiated precursors for further work, the client faced abandonment of the project.

In discussions centered upon future windows of opportunity to process additional samples, the client was introduced to the variety of Plastic mold resources and interdisciplinary team of specialists that could be assembled to move the project forward without substantial delay. The proposal presented to the client expanded the scope of work to include creation of a small polymerization system and synthesis of the triblock coRandpolymer precursor. Within three weeks, the project was back on track and demonstrating the best features of the nascent rapid prototype Method.

From CAD to prototype

What is rapid prototyping software?
The activity of rapid prototyping software is an important part of software development. It is important to create prototypes of the software to test the software’s workings. These prototypes are actually incomplete versions of the software program that is underway in development.

How does rapid prototyping software work?
The main features of the software being prototyped are first looked at. In rapid prototyping software, the plastic mould prototype being developed does not perform the entire functional spectrum of the software, but only simulates some of the plastic mould aspects or features. The actual and eventual program may be very different from these simulations of it when it is actually implemented.

Why rapid prototyping software?
Conventionally, the purpose of rapid prototyping software is to let users of the eventual software an evaluation of the design proposals given by the developer. Users are allowed to actually try out the simulations so that they do not have to make an plastic mold evaluation decision based solely on descriptions of the program and can actually get a sense of it before making a judgment.

Many a times, there are requirements that developers have not thought about that users might actually find useful. rapid prototyping software allows users to bring this to the notice of the developers and therefore betters the commercial relationship between the client and solution providers.

Benefits of rapid prototyping rapid prototype software
1. The designer and implementer of the software get to obtain feedback directly from the users who would be using the final product. Therefore, he can customize it to be a success right from its inception and increase its probability of becoming a hit.
2. Clients can actually do a match of the rapid prototype software specifications they have provided with the software being developed and therefore any changes that need plastic mold to make can be done then itself.
3. The software engineer is given an opportunity to check on the accuracy of the initial project and whether planned deadlines and milestones can be achieved in time.
4. Since the 1970s, the techniques used in rapid prototyping software have been refined time after time to make them work with the efficiency that they do now.

Historically speaking
The process was present way back in the1960s itself. As can be assumed, the development cycle of an entire software program and its building was quite monolithic. Working out mismatches between the decided design, specifications and the finished implementable program would cause much waste of time, effort and money. This approach, also coined “Slaying the (software) Dragon” approach, puts all the pressure on the software designer who also then becomes the developer and he has to manage the entire “dragon” slaying by himself.

As time went by, easier methods to avoid these inconsistencies were found and therefore, saving cost rapid prototype , time and effort became possible. The finished software met not only the clients’ specifications but was able to modify itself to users’ benefit.

Permit me ask you: what would you think if you hear that you will generate a part on a PC and then you will hold and evaluate that half 45 minutes later? As a matter of reality, it’s not just my imagination – it’s a reality! What would are unbelievable several years ago is now well established technology due to three-dimensional rapid prototype printers build it possible.

You need additionally to stay in mind that there is a method of creating prototypes involved 1st creating 2-dimensional drawings of a half and then taking those drawings to a model maker to form the prototype. This plays a important role, the model maker would initial have to correctly interpret the drawings, and then a process for making the prototype was identified. To the best of our data, once the half was created, the engineer ought to examine and live the part carefully to create certain that it fell inside the specifications on the drawings. We have a tendency to have every reason to believe that if it did not pass inspection, the half would wish to be modified or scrapped and the entire method would begin everywhere again.

However currently there’s an alternative to the current method: imagine taking the same part that took days or perhaps weeks to make and having it in your hand in 45 minutes. The process is kind of incomplex: a part is made digitally on a pc using 3D modeling software. As way as it’s ready, the file is then saved in a common format and sent to a 3D printer. The other useful thing to feature is that the printer builds the half one skinny section at a time from the bottom up putting water soluble supports in where necessary.

Really, it takes from 20 minutes to many hours to complete relying on the scale and difficulty of the part. What’s more important, the part is off from the printer, placed in a very detergent solution to dissolve the supports, rinsed, dried, and is back in the engineer’s hands on the identical day. In addition, it should be additionally said that the dimensional accuracy of the part is in fractions of a millimeter, thus most elements do not require further measurement and verification.

It’s no nice surprise that it virtually sounds too good to be true. Not to mention, these printers have become relatively cheap in recent years, and whereas there are still some expensive models, of course, there are very useful 3D printers that are relevantly not expensive.

Therefore, to form long story short, the process of making the rapid prototype doesn’t take long as to the time, material, and labor savings and your money would be paid off terribly fast. To sum up, 3D printers are by way one among the most intriguing components of digital rapid prototype, and the printer build the part one layer at a time quietly.

The method has a number of key distinctions: Unlike traditional, linear models of rapid prototype product development, it’s a cyclical process where one cycle inputs into the next and where a variety of solutions move repeatedly through a range of stages. It integrates rapid prototype and multidisciplinary teams to allow numerous, and nearly simultaneous, iterations.

Inspired, in part, by approaches and techniques commonly employed in food industry test kitchens, this method requires a devoted team, incorporating all appropriate disciplines and allowing a broad range of process options for comparison and contrast as to efficacy, scaling and suitability.

This method typically postpones confirmation of a concept until several iterative cycles have been conducted, to preserve flexibility and to allow incorporation of new ideas into a synthesized set of solutions. Traditional approaches frequently focus early on a preferred outcome rather than permitting the open consideration of alternatives.

In rapid prototype, numerous potential processes may be evaluated and ranked for strengths and weaknesses. Experimental work and iterative prototype testing determines the right combination of conditions for each potential stage or step in the process. By combining unit processes that are most promising, a new process train can be defined, installed and tested, incorporating the best attributes and practices of the variations considered. And, of course, as with tasting in a “test kitchen,” the product is sampled, analyzed and tested without delay.

Why outsource development?
Companies outsource work for many reasons, often expecting to reduce costs and time to completion or to resolve resource availability issues. Sometimes the reason is safety, secrecy or anticipated production problems.

Many companies presume that cost is the easiest factor to assess and, consequently, they allow the purchasing department to evaluate the decision to “make or buy” developmental services. Unfortunately, many purchasing executives lack the information for an in-depth analysis and understanding of all relevant costs and risks. For example, in comparing the “price” quoted by an independent facility to an internal “budget,” a purchasing executive may ignore critical risk factors or competition for internal resources simply because that information is not presented to him.

Some companies have saved millions of dollars by employing outsourced facilities to take the risks in scale-up, notable among them, firms in the pharmaceutical industry. There are several examples in our database where the world’s foremost experts in a particularly narrow field of chemistry learned to their horror that the impossible does occur.

In one memorable case, a client company assured us that its fluorinated product was entirely stable and couldn’t damage our all-glass, high-vacuum distillation system. The glassware was replaced. Had this work been performed in the client’s facility, the notoriety and delays in incident investigation and equipment replacement might have had disastrous consequences for other products and work scheduled in their facility.

“There are so many constraints for companies — some initially unforeseen — in new product development,” says Mike Keenan, a retired senior chemist from Exxon who has worked and consulted on a number of projects at Pressure Chemical. “Since many companies are committed to existing technologies, it’s difficult for them to have the equipment, capital and, sometimes, the mindset to develop new products and processes efficiently. And companies vary in their strengths. Some are superb at taking someone else’s process and making it more efficient and effective. Others are better at discovering a new process from scratch. In any event, outsourcing certain stages of the product development process can bolster total development efforts,” according to Keenan.

“You need to develop new products outside of the typical constraints of manufacturing, preferably where you can brainstorm for ideas with operators, chemists, mechanics, engineers and regulatory specialists,” Keenan added. “You need to be in a place where change is anticipated and facilitated, not where change requires sign-off at several levels and can take weeks or months.”

Changing equipment and process procedures are germane to the development process. “Unanticipated issues arise during scale-up; it’s common to change equipment and conditions midway through the development process, even during the course of a reaction” said Brandon Ritchie, a senior project manager at Pressure Chemical. “It’s much easier to change something in a well equipped pilot plant than in a client’s production facility. Safety, flexibility and speed are everything in process development,” he added. Pressure Chemical’s project leaders are given full authority to accept client initiated changes in equipment and operating conditions so long as the change conforms to defined safety requirements.

For example, a new client project required some dramatic modifications to the distillation of a high melting monomer. The attempted distillation resulted in a lot of freezing in the process piping. The problem was solved by injecting an appropriate solvent into the overhead to deliver the product as a solution. “We had the ability to modify the equipment quickly and to develop a new, highly successful process for the distillation,” Ritchie said, adding that this preserved the delivery schedule for the product.

Regulatory issues
Large rapid prototype Shenzhen companies are well aware of the impact of federal, state and local regulatory issues in product and process development. Smaller companies, especially ones that do not manufacture novel chemical products, may be totally unaware of the regulations affecting new chemicals. An independent pilot facility that specializes in innovative materials maintains an awareness and working knowledge of the rules, limitations and regulations impacting its customers’ development efforts. For those without the internal regulatory capability, an early consultation with an independent pilot facility should at least identify regulatory issues.

Rapid prototype Tooling are often made using FDM technology. The part was made from extruded black ABS and was used for some functional testing.

Initial prototype

3M began this phase by creating stereolithography (SLA) patterns with its in-house SLA equipment. Overflow SLA work was sourced to Vista Technologies. The SLA prototypes were used by engineers and industrial designers to check fit and form. The same prototypes were used by 3M packaging engineers to create conceptual mock-ups of product packaging. They also made excellent tools for ergonomic and usability studies.

To mimic the soft under pad of the sanding tool, Vista used PolyJet(TM) rapid prototype technology. PolyJet was chosen because it can use either of two soft-durometer (a hardness measurement) materials that can be run to gain similar quality parts as SLA technology. TangoBlack, a material with a score of 61 on the Shore A durometer scale, was the best fit. Within days Vista was able to supply 3M with their simulated soft-durometer under pads for more testing.

The bottom pad for the hand sander was prototyped using TangoBlack material from the Polyjet technology. This material is a 61 Shore A material that mimics the properties of santoprene.

At the same time, a gripping/tensioning mechanism for the sanding media was being developed. At this point, the sub-assemblies were merged into a refined set of CAD databases. Additional SLA parts were created to evaluate the new mechanisms. With each new prototype, the team was able to investigate new features in the design. Because these rapid prototype parts could be created cost-effectively in a matter of hours instead of days or even weeks, the team had the ability to study complex forms and details in a manner not possible using traditional machining and fabrication techniques. In some cases multiple iterations were generated in one or two days.

Second-Generation Rapid Prototypes: More Realistic Simulations
In the second generation of the prototypes, 3M needed the hinge function and material properties to be simulated more realistically. After a few design changes were made to the CAD data, Vista Technologies supplied 3M with a Fused Deposition Modeling (FDM) prototype.

The FDM part, made from extruded black ABS, allowed for more robust testing and provided similar specified material properties in weight and strength as the final part would have. This prototype was able to handle a variety of tests that allowed 3M to modify their design before production tooling was released.

Rapid Tooling Takes Over

Once 3M completed its work with prototypes, it was time for rapid tooling. Vista Technologies quickly created aluminum tools. Milled at 42,000 rpm with high-speed milling technology and a proprietary fixture system, these tools were made for quick turns and quick modifications.

The aluminum tools could be modified, polished, textured, welded on, and were capable of shooting 10,000-plus parts. Vista Technologies supplied injection-molded parts within two to three weeks of usable CAD data. By getting specified material parts in hand, 3M could complete their required testing.

The rapid tools supplied by Vista Technologies were for multiple parts that made up the sanding products. The parts were made in family tools–meaning several related parts were made in the same tool. By adding runner shut offs to the tools, 3M could turn on or turn off certain parts of the tool–thereby making only the parts they needed. This kept costs down while minimizing wasted material in extra mold inserts. The molds were made with hand pick-outs and manual slides to capture several undercuts in the part design.

3M chose the rapid tooling approach because it allowed them to quickly evaluate different part features and molding parameters. Tooling changes could be completed and parts resampled for evaluation in just a few days. This was a tremendous advantage to 3M.

From an engineering standpoint, they were able to sample several materials for strength and repetitive testing. They were also able to compare the functionality of various latch mechanisms and to check material flow and gate locations (points where material is injected into the tool).

From a marketing standpoint, along with sampling different materials, they also were able to mold parts in a variety of colors to get important feedback from focus groups. By the time databases were released for production tooling, the mold designs had been optimized and the material and color strategies were in place.

By using rapid tooling, 3M discovered many things in the functional prototypes before cutting production tools. The gating was changed on the production tool, the snap-fit features were redesigned, the handle was modified and ultrasonic energy directors were added for sonic welding of parts in final assembly.

Summary

As rapid prototype and rapid tooling technologies become more sophisticated, the importance of picking the correct technology for product applications can be critical to gaining a competitive edge. As 3M found, a combination of RP and RT technologies and materials helped them save money, speed development time and establish a foothold in the marketplace.

rapid prototype is a process wherein a working model or prototype is developed for the purpose of testing the various product features like design, ideas, features, functionality, performance and output. This process of development of working model is quite quick. The user can give an early feedback regarding the prototype. Rapid prototyping is, generally, a significant and essential part of the system designing process and it is believed to decrease the project cost and risk.

The rapid prototype that is developed by the process of rapid prototyping is based on the performance of earlier designs. Hence, it is possible to correct the defects or problems in the design by taking corrective measures. The product can be produced if the prototype meets the requirements of all designing objectives after sufficient refinement. There are many advantages of rapid prototyping.

Rapid Prototyping -Advantages in brief: Rapid prototyping has manifold advantages. It can provide with concept proof that would be required for attracting funds. The prototype gives the user a fair idea about the final look of the product. Rapid prototyping can enhance the early visibility. It is easier to find the design flaws in the early developmental stages. Active participation among the users and producer is encouraged by rapid prototyping. As the development costs are reduced, rapid prototyping proves to be cost effective. The user can get a higher output.

The deficiencies in the earlier prototypes can be detected and rectified in time. The speed of system development is increased. It is possible to get immediate feedback from the user. There is better communication between the user and designer as the requirement sand expectations are expressed in the beginning itself. High quality product is easily delivered by way of rapid prototyping. Rapid prototyping enables development time and costs. There are many innovative ways in which rapid prototyping can be used.

Despite all these benefits, there are many people who believe that there are many disadvantages of rapid prototyping.

Disadvantages of Rapid Prototyping: Some people are of the opinion that rapid prototyping is not effective because, in actual, it fails in replication of the real product or system. It could so happen that some important developmental steps could be omitted to get a quick and cheap working model. This can be one of the greatest disadvantages of rapid prototyping. Another disadvantage of rapid prototyping is one in which many problems are overlooked resulting in endless rectifications and revisions. One more disadvantage of rapid prototyping is that it may not be suitable for large sized applications.

The user may have very high expectations about the prototype’s performance and the designer is unable to deliver these. The system could be left unfinished due to various reasons or the system may be implemented before it is completely ready. The producer may produce an inadequate system that is unable to meet the overall demands of the organization. Too much involvement of the user might hamper the optimization of the program. The producer may be too attached to the program of rapid prototyping, thus it may lead to legal involvement.

The cost reduction benefit of rapid prototyping also seems to be debatable, as sufficient details regarding the calculation basis and assumptions are not substantial.
