valve gate HRS


The principle of valve gate hot runner system is that the valve needle can close the injection nozzle and keeping the plastic material in melting condition. There will be no waste material in valve gate hot runner system.

The advantage of valve gate hot runner system:

reduce the tooling cycle time and increase production efficiency
It replaces the cold runner system, no waste material, save a lot of raw plastic material
It increase the consistency of product, no raised place on the injection gate, avoiding the failure on injection mark
It would make products better in appearance
I can reduce the tension of product, reduce the crisp force caused by the out of shape and structure,increasing the ability to produce complicated products and life
Providing more technical support in high precision adjustment
Valve gate hot runner system is suitable for every type of plastic material

Normally,valve gate hot runner system is consist of hot runner manifold,nozzle and temperature controller. The manifold and nozzles are contacting with injection machine. The melting plastic material will flow from injection machine to manifold and then to nozzles. The material in separate branches will be injected into the every cavity through nozzles, which can fully decrease the inner stress of product and improve the quality of products.
