Therefore, the nozzle temperature of molding ponent will have an important impact. 4 Precision Molding Technology Application of The Mold Injection Compression Molding (ICM) Technology ICM Technology is the means to open a certain distance from the mold under the conditions of the beginning injection, injection of a certain amount, close to the beginning die cavity melt implementation of the pression, Die pletely closed at the termination of injection, and then packing, cooling until the removal products. The Highspeed Injection Molding Highspeed injection molding method of filling melts faster than traditional fast 10 ~ 100 times, so that melt in a mold cavity to produce high shear flow and viscosity, mold filling fast, plastic surface hardening slowed, will be enhanced thinwall molding thickness limit, inhibit excessive molding pressure and lowpressure die as mobile, products, the lower the stress. No Guarantee Pressure Injection Molding Without packing injection molding technology is referred to the plastic melt in highspeed, high pressure filling into the mold, then close to the nozzle needle, a plastic mold cavity melt automatically cover all parts of the product contraction Such products can greatly reduce the warpage. Other Intelligent Control Technology Precision injection molding process on the processing conditions for continued monitoring and accurate control is very important. With the development of puter technology, puterized injection molding has been widely used . 5 Conc
