In the world of industrial more developed countries and regions,Hot runner mold production are extremely active.Percengtage of hot runner mold is incresse. Many of the small factory under 10 people is producing hot runner mold.Generally speaking ,Noth Amercian and Europe use hot runner technology with longer time ,and have more experience. In Asia, excluding Japan, Singapore, South Korea, Taiwan, Hong Kong is in the lead. North America, Europe, even though high levels of mold, but the higher prices longer delivery. In contrast, Asian hot runner mold manufacturers on price and delivery have more competitive. China hot runner mold is still in its infancy, but is growing rapidly, the proportion rising.international profile of hot runner mold
Hot runner mold in the electronics, automotive, medical, daily necessities, toys, packaging, construction, office equipment and other industrial sectors are widely used. 3. Industry Hot runner mold parts with the minimum of 0.1 g or less. Maximum of 30 kg. Extremely broad and flexible application.2. Part size and weight Hot runner mold has been successfully used for processing various plastic materials.Such as PP, PE, PS, ABS, PBT, PA, PSU, PC, POM, LCP, PVC, PET, PMMA, PEI, ABS / PC and so on. Any can be used cold runner mold plastic materials also can be used with hot runner mold.1. plastic materials
he application of hot runner mold 
Plastic flow in hot runner system need balance. To open the gate while simultaneously filling the cavity to make plastic. The parts are significant differences between the weight of the FAMILY MOLD size design should be balanced runner. Otherwise, there will be some parts filling packing unenough, some parts are filling packing too much flash and poor quality. The design of hot runner size should be reasonable. Size is too small will filling pressure loss is too large. Size too big, too hot runner volume. plastic in the hot runner system to stay too long and caused material property damage after molding parts can not meet the requirements. The world has been designed to help users make the best flow of the design of CAE software such as MOLDCAE. 
2. Plastic flow of control 
In application of the hot runner mold,plastic temperature control is extremely important.Occurred during the processing of production and product quality.Problem directly from the poor hot runner temperature control system . Methods such as using hot needle injection molding gate when the poor quality of product issues, methods of forming gate valve closed when the valve needle difficult issues, many parts mold cavity filling time and inconsistent quality problems. If possible should be selected with multi-regional difference in the hot runner temperature control system to increase the use of the flexibility and adaptability. 
1.Plastic temperature control 
Application projects of a successful hot runner mold require multiple links to be protected.And there are two technical factors.One is plastic temperature control,second is the control of plastic flow.
