Mold enterprise gradually more up now, and many industry rising to the requirement of the mould, so the precision mold industry development gradually hot up, with the vigorous development of the electronic information industry and traditional industry informatization modification, plastic mold market prospect of a vast, global high-grade, precision plastic mould market is in short supply situation.

In recent years, China plastic mold manufacturing level has been improved greatly, the production of large single set weight of the plastic mould has reached more than 50 t, the accuracy of precision plastic mold has reached to 3 cm, already can produce a multi-cavity mold plastic mold cavity encapsulation molds, 7800 high-speed molding aspect has been able to produce extrusion speed of more than 4 m/min high-speed plastic different profile extrusion die and the main profile double co-extrusion die cavity. Along with the
