Plastic Injection Molding Equipment

Making polymers is a fantastic science. Then there is the matter of shaping the plastic into useful objects....another fantastic science. One of the most common methods of shaping plastic resins is a process called injection molding. Injection molding is accomplished by large machines called injection molding machines. A type of mold used in the process of injection molding. The mold usually comprises two sections held together by a clamping device with sufficient strength to withstand the pressure of the injected, molten plastic. The mold is provided with channels for heating, cooling and venting.

The corporation specializes in plastic injection molding, injection molding plastics design, custom injection molded plastics manufacturing plastic in China and Taiwan at their manufacturing facilities. CAD plastic injection molding designer services are performed in Taiwan assisted by their engineers in the US. Rapid prototyping capabilities also compliment their plastic injection molding in China capabilities for customers in need of SLS prototypes quickly, for modeling and proof of design or concept. Their rapid prototyping, SLS and custom molding and plastics machining capabilities can get your new designs in solid form in a short amount of time.

Approximately 30% of all plastic products are produced using an injection molding process. Of this 30%, a large amount of these products are produced by using custom injection molding technology. Six steps are involved in the injection molding process, after the prototype has been made and approved. The first step to the injection molding process is the clamping of the mold. This clamping unit is one of three standard parts of the injection machine. They are the mold, the clamping unit and the injection unit. The clamp is what actually holds the mold while the melted plastic is being injected, the mold is held under pressure while the injected plastic is cooling. Next is the actual injection of the melted plastic. The plastic usually begins this process as pellets that are put into a large hopper. The pellets are then fed to a cylinder; here they are heated until they become molten plastic that is easily forced into the mold. The plastic stays in the mold, where it is being clamped under pressure until it cools. The next couple of steps consist of the dwelling phase, which is basically making sure that all of the cavities injection of the mold are filled with the melted plastic. After the dwelling phase, the cooling process begins and continues until the plastic becomes solid inside the form. Finally, molding the mold is opened and the newly formed plastic part is ejected from its mold. equipment The part is cleaned of any extra plastic from the mold.

The company not only runs the plastic parts on custom automotive plastic injection molding machines, they manufacture the tooling for these operations as well, and are able to provide automotive connector molding for many of their clients. This allows the company to provide very competitive pricing on large plastic parts manufactured in China for distribution anywhere in the world. The company is capable of producing custom automotive plastic injection molding plastic products in all types of engineering grade resins requiring close-tolerance specifications with superior quality and aesthetics. They carry various CAD software programs to injection ensure we can assist you using most of today's programs.

Injection molding is a common method of producing intricate plastic components in high volume. Injection molds are made from hardened tool steel, although aluminum may be used for some low volume applications of injection molding. Injection molds can vary from simple open-shut injection molds, single cavity injection molds to complex multi-cavity injection molds with moving cores, stepped shut-offs, unscrewing devices. Due to the tonnage used in this high pressure process, proper materials, supports, parting line locks etc. must used to ensure the life of the mold. Cavities may be polished or textured to achieve a desired finish on the injection molded part.
