Valve needle hot runner, good color change performance, suitable for most plastics, good flow performance, very fine gate marks. Valve gate hot runner system plastic mold structure is the most complex. It has the same structure as the common multi-head hot runner system plastic mold

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 plastic material that can be machined with a cold runner mold can be machined with a hot runner mold

1, shorten the forming cycle of the parts because there is no limitation of the cooling time of the runner system, the parts can be ejecting in time after forming and curing. Many thin-wall parts produced with hot runner molds can be formed in less than 5 seconds in a pure hot runner mold because there is no cold runner, so there is no production cost. This is particularly significant

Integral hot runner is an advanced hot runner system in injection molding, which integrates all components of the hot runner system in the mold design and manufacturing, and has the advantages of simplifying the structure, improving production efficiency and optimizing product quality. This paper will introduce the application

Hot runner An important step is the design concept of hot runner. A detailed design concept, including manifold and platen, will be an important part of the mold audit.The manifold is used to ensure that the liquid channel is arranged in the most efficient manner

The two-stage heating nozzle processing technology is to heat the processed plastic particles by the injection molding machine to ensure that the plastic of the runner and the gate remains molten for injection molding. In the production of existing plastic products, the melted plastic is injected into the mold to be formed in a hot runner system consisting of a hot nozzle, a valve needle, a heater
