A success hot runner system for mould should be guaranteed by many links. And the most important key technology of hot runner applications is as follows:
1. plastic temperature control
In the application of hot runner system mould, plastic temperature control is very important. Many problems appeared during processing and the products quality is rooting in the bad temperature control of hot runner system. Just as using valve gate nozzle to inject the plastic products and turn up the products bad quality of nozzle, the difficulty of the closing valve needle, the quality and inject time of multi-cavities mould is incongruent and so on. If you can, pls choose more temperature controlling to control hot runner system to increase flexible of using and adaptability to change.
2. plastic flow control
The plastic should keep a balance flow in hot runner system. Open the sprue I the same time to fill the cavities. With regard to the differ greatly weight of parts, the mold needs a sprue dimension designing. Otherwise, some parts mold filling pressure maintaining will be not enough, over or has a big pverlap and bad quality and other problems. Hot runner sprue dimension should have a reasonable design, too small will cause losing pressure, too big will damage material property and cause the parts shaped with unsatisfing using demands. There are mould flow soft ware to help customer to set the best hot runner design.
Last week Anole hot runner attends Chinaplas in Shanghai. There are so many exhibitors and visitors come and visit our booth to talk about the key technology of hot runner application and business relationship. If you have any problem of hot runner system, we will try our best to help you.

In the injection molding processing, hot runner played more and more important role in injection, hot runner system application has been widely and widely. Correct application helps to save the plastic material also help to improve the productivity.

In the injection molding processing, hot runner and mold used coordinated, and playing very important role. For example, in the be ultra-thin injection molding production (for example handset battery cover), through uses the hot runner easy to produce high accuracy high grade product; Regarding the bad fluid injection molding material (for example LCP), through uses the hot runner to be able to improve raw material fluidity obviously, guaranteed that the injection molding production carries on smoothly; Regarding some large-scale injection moldings, after like automobile's bumper and shutter, television, the shell, the air conditioner outer covering and so on, through use the hot runner, make the difficult injection molding becomes the relative simplification. In the multi-die space's mold injection molding, lacks the hot runner unable to take shape radically. It can be said that the hot runner is the best technology guarantees the runner balanced. Because the plastic has the shearing force in the hot runner, regardless of the mold has the reasonable geometry balance, takes shape the product weight which comes out to be difficult consistently, specially speaking of the multi-die space's mold, if does not use the hot runner, will take shape the product flank which will come out the inside to be lighter.
