This is Episode 1 of a series of video blogs on Additive Technologies (also known as Rapid Prototyping). Today we’re looking at the Multi-Material Polyjet machines which can mix both rigid and soft materials together on the fly to grow parts that simulate over-molding and other complex applications. This process is great for small to medium sized parts (it’s not always cost effective for large parts) and is often used for a variety of prototyping applications (the material is not usually suited for end-use applications), creating a direct tool for a silicone mold, and investment casting.

We are a group of engineers, mechanical/industrial designers, entrepreneurs, and inventors, that have a passion of creating innovative ideas and inventions transforming them into physical reality. We start with conception sketches for visualization and help all the way through the product development cycle. We create prototypes by designing 3D CAD interactive parametric models using Solidworks, autocad and other 3D software. We can then create 3D pictures using graphic design and graphical animations(movies) so you can visualize exactly how your idea will look, work together, and function. We can then create a functional prototype using a 3D rapid prototype printer using FDM(Fused Deposited Material) out of ABS custom plastic. We can also do electrical hardware, PCB boards, and software. We are also a 3D laser scanning service bureau, using the scanner we can reverse engineer existing products or out of production parts. 3D software then digitizes it creating a 3D stl model that you can create cad models if needed, then modify them. We have connections to other professionals that we can get your product patented and protect your intellectual property. We also have a network of manufactures, factories, CNC machine shops, injection molders, and more. Let us get your ideas in your hand quickly!

In plastic part design, technology has given us a variety of prototyping options. Rapid prototyping (RP) includes stereolithography, selective laser sintering, fused deposition modeling, laminated object manufacturing, and three dimensional printing. Each of these builds 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 an initial part and then creates, from that part, a mold in which additional parts can be made. Mold materials can range from silicone rubber to composites. A third prototyping option is rapid injection molding (RIM), which works directly from a 3D-CAD model, using CNC machining to mill aluminum molds in which true injection-molded parts can be made. Finally, there is traditional injection molding, which is used primarily for production, but could conceivably be used to create prototypes.

Rapid Injection Molding

Rapid injection molding is exactly what its name implies, but at a rate 10 times! It is difficult to imagine a service that one can fully operate in a mold or guarantee two days would bring, but in fact the case.
This is the case with rapid injection. Quickly, quickly! These forms made from high quality aluminum and can produce several thousand species.

Personally, I have several aluminum molds that produce parts of high quality work, even after several hundred thousand cycles. At first I was skeptical, but after a few years to make injection molded prototypes, it became routine.

 It works by automating as much as possible in making mold. For the model D-3 client and automate the design and production of the form will reduce the time a part of traditional methods. One of the central parts of the automated process is the shape of the plastic part. By working with experienced designers can use many features such as undercuts the disadvantages minimized or eliminated.

 What are the advantages of rapid injection molding?

One way to bridge the gap of time between the original and full production. If you have a mold for the work is now needed is the answer. The short production time for your product on the market to escape. It provides users with a working model of a design approach for a mature production tool.

What are the disadvantages of rapid injection molding?

The aluminum molding is the low production costs. It works best for simple action parts and minimal side effects disadvantages of denial. EDM is removed, some details may be sacrificed. The core of the whole cavity and high speed CNC-milled, the design has its limits.

Rapid injection is expensive Paradoxically, the cost is quite reasonable, but there is always a premium for quick recovery to pay. In general, the cost much lower than imaginable. This is due to automate the process point of this kind of form.

The early conclusion of injection molding is a part of the niche market of injection molding. It serves a niche market, but it is very important for the chime. It can get your share of plastic injection market a matter of days is very valuable for the right company. Furthermore, the ability to bridge the gap between prototyping and production of high bridge is a very useful tool for custom Injection molder. Randy Hough lives and works in the upper valley of Vermont. He has master plastic injection toolmakers traveled for 30 years, a youth pastor for many years and many studies in Europe. It has 8 children very much alive and who have learned more than anything else. He has a website on how to deal with family stress and a plastic injection molding download site.

Rapid Plastics – Injection Molding?S Basics

Injection molding is a manufacturing technique for making parts from both thermoplastic and thermosetting plastic materials. Heated, fluid plastic is injected at high pressure into a plastic mold, which is the opposite of the desired product shape. Injection molding is widely used for manufacturing a variety of parts, from the smallest component to entire body panels of car.The process of injection molding can be described in four simple steps. These include Plasticizing, Injection, Chilling, and Ejection. Each of these steps is different from the other and the right procedure is required for the successful completion of the total process.

These steps can be discussed as follows:

Plasticizing
IT involves the conversion of the polymer material from its normal hard granular form at room temperatures, to the liquid which is necessary for injection at its correct melting temperature.

Injection
This is the stage during which this melt is introduced into a plastic mold to completely fill a cavity or cavities.

Chilling
It is the act of removing heat from the melt to convert it from a liquid consistency back to its original rigid state.

Ejection
The ejection phase is the last phase where the removal of the cooled, molded part from the plastic mold cavity is done.

Pelletized or powdered materials that are used in injection molding machines are mostly:

o Ethylene
o Polystyrene
o Polycarbonate
o Polypropylene
o Acrylonitrile-Butadiene-Styrene (ABS)
o Nylon

The use of these basic steps in sequence or as a cycle is the process of injection molding done to obtain or manufacture parts. Cycle time usually ranges from 10 to 100 seconds and are controlled by the cooling time of the melted plastic. The melted plastic comes from hard rapid prototype plastic pellets that are fed into the hopper of the injection-molding machine. The pellets or plastic powder is melted inside the machine and then forced into the mold through a nozzle by a long screw within a heated cylinder. It is the most common method of production, with some commonly made items including bottle caps and outdoor furniture. Injection molding typically is capable of tolerances.

Plastic molding applications are used in medical field like components for blood analyzer equipments, heart pump parts, orthopedic devices and custom knee braces. In automotive engineering it is used for mechanical levers, gears, gaskets and switches. It is also used for aerospace, automotive, avionics and computer components.
