The application of ultra high speed injection molding in the thin piece is generally divided into three categories, one is a product belongs to daily necessities, characterized by small, but the forming size requires less precision, such as aviation, food containers, food tray, vase; second is the electric machinery parts, except for ultra-thin the characteristics, has the size precision parts, such as intake manifold, oil seals, bearings, seals, piston ABS, pinion, horn net, plastic screen, SD card; third is the electronic information products, not only the size requirements of precision, but also finished the mechanical, optical, and electrical characteristics are different requirements, such as CD, DVD, non-contact IC card, optical fiber connector, connector, the read head bearing, IC slot, IC tray, watch or camera parts etc..
Injection molding machine, injection molding machine or injection machine. It is the main forming equipment plastic products, thermoplastic or thermosetting plastics using plastic molding into various shapes. Divided into vertical, horizontal, all electric. The function of heating plastic injection, high voltage is applied to the molten plastic, so that the injection and full of mold cavity
