Injection molding processes create some of the smallest microcellular parts in the world. These parts and pieces are used for automobiles, construction, and other items. Additionally, the use of insert molding magnets helps to complete the injection process. One of the most common processes includes items that may come from polyurethane Reaction Injection Molding (RIM) processed materials. With the different materials used in this process, any of them may be cells as small as one-thousandth of an inch.
The Injection Molding Process for Microcellular Systems
Many different processes can produce various prototypes and microcellular items. Some of them are RIM or even the polyurethane injection molding process that includes a combination of two liquid components. Within all of the injection molding processes, there may be a combination of polyurethane, polyureas, polyisocyanurates, polyester, polyphenol, polyepoxide, and nylon 6. It could be the creation of a fiber mesh or a foamed material, though some of the thicker ones are solids used for walls in construction.
Other Encapsulation Molding Processes
In the same way, encapsulation molding designs a mold that will develop some of the smallest parts needed for construction or other industries. Some parts are used for walls developed at about one-eighth of an inch up to one-half an inch. The injection molded enclosure has the ability to help with encapsulation where those parts are intended to fit.
Injection Molding and The Insert Molding Magnet
Various processes work together to complete injection molding. The different molding processes such as the reactive encapsulation molding process. In addition to the process, adding an insert molding magnet can help improve the process overall. While injection molding may be easily able to make prototype microcellular parts, there is also the to develop a chemical foam that is able to be injected to a capsule or structure that presents the shape of the part to be constructed. Different reaction molding processes are able to make polyurethane and other parts by the creation of a chemical reaction and eventual curing.
In all of these processes, after two liquid components are combined, a chemical reaction is used to create a foam that will be molded into a microcellular part. Incredible pressure is also applied for the finalization of a part construction. The pressure is anywhere from 1500 to 3000psi in order to help create a plastic part from the foam that came out of the chemical reaction.
With all of these different small, or event microcellular, parts are needed for different industries, the ability to create a mold and a prototype with a pressurized foam is a very specific procedure. No matter the process that is chosen, a chemical reaction of different liquids is able to provide the base material to create any number of tiny parts that are able to help with the construction of homes, cars, and many other items.
