Nowadays, molded screw threads are everywhere -- on the cap of a Coca-Cola bottle, on the nut linking the drain pipe to the underside of the kitchen sink. So here comes a lot of screw thread plastic injection molding companies to perform the process of screw thread mould. GM-TECH, as a leading custom plastic injection molding company, will continuously spare efforts to produce high quality injection molds.

Two Shot Injection Moulding, also known as dual-shot, multi-shot, allows engineers to create multi-material or multi-colored parts without other steps. It is a kind of plastic raw materials of injection molded parts after the parts out, fed into the second mold again with the same or another plastic material molding process.

Vacuum Moulding Plastic to the use of the original template to make a silica gel mold in the vacuum state, and pour it with PU material in the vacuum state, so as to clone the same replica as the original template. This is similar to the processing method of custom plastic injection mould. Products can use any material, such as ABS, PC, PBT, PA66 and so on. But its disadvantage is that the product precision is low and the die life is short!

The characteristic of plastic injection mold and molding is that the plastic raw material is placed in the heating barrel of the injection molding machine. The plastic is melted by heat, driven by the screw or plunger of the injection molding machine, enters the mold cavity through the nozzle and the pouring system of the mold, and the plastic is formed by heat preservation, pressure retention, and cooling in the mold cavity. Since the heating and pressing device can function in stages, injection molding can not only form plastic parts with complex shapes, but also has high production efficiency and good quality. Therefore, the injection mold occupies more than half of the proportion in the molding of plastic parts. Injection molding machines are mainly used for the molding of thermoplastics, and in recent years have gradually been used for the molding of thermoset plastics.

China rapid injection molding prototyping technology is a fast, convenient and practical mold manufacturing technology. The characteristics of prototype mold making are: short molding cycle, simple process, easy popularization, low molding cost, precision and service life, which can meet a specific functional needs, and good comprehensive economic benefits.Prototype mold making is especially suitable for new product development and trial production, process verification and function verification, as well as multi variety and small batch production.
