Vertical Plastic Molding Machine

The corporation specializes in plastic injection molding, injection molding plastics design, custom injection molded plastics manufacturing 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 vertical 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 plastic 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 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, the mold is opened and the newly formed plastic part is ejected from its mold. The part is cleaned of any extra plastic from the mold.

Silicon molding services produce molded components made from silicon. Liquid silicone is similar to normal silicone, but has different processing characteristics. It is purchased as a two-part raw material with a grease-like viscosity. Nowadays injection molding of liquid silicon rubber is becoming increasingly important. One reason for this is the increased performance requirements of the finished articles. In addition, more and more producers of rubber parts are seeing benefits in the high level of automation and productivity. Why the preferred use of silicon rubber in injection molding Silastic silicon rubber is a shear material and so its viscosity depends on shear rate. As the shear rate rises the product becomes lower in viscosity. It is this effect that is very favorable for the injection molding process. molding At the beginning of the injection process the injection speed profile should be programmed in such a way that the volume flow is high enough for the liquid silicon rubber not to begin to vulcanize before the cavity is filled, in order to avoid scorch of the material. Thus liquid silicon rubber is widely used for the process of injection molding.

The ability to reverse engineer existing molds and molded parts allows us to build new and improved custom tooling for the customers. Digital data files and computerized machining are used almost exclusively for tooling of plastic injection molded custom molds. Computerized plastic injection molding machines in China are used almost exclusively for production. For plastic injection molding in China aluminum short-run rapid prototype molds are faster and are an economical solution for customers needing to prove out new part and product designs prior to production tooling. The company specializes in plastic injection molding in China to produce a wide variety of products from high-tech parts with very tight tolerances to children's toys and entrepreneur's inventions. Some examples of these products are pictured to the right.

Reaction injection molding is used in many industries for many types of parts. While bumpers for vehicles are produced in this process, most applications are for large, complex parts produced in quantities less than 5,000 units. Examples include panels for electrical equipment, enclosures for medical devices, and housings for computer and telecommunications equipment.
