Valve needle type hot runner working principle is install the hot runner nozzle and manifold on to the injection mould. Use the heating theory, make the plastic keep melting from the injection machine barrel. That will makes the product injection surface same like connect to the injection machine nozzle directly. When demoulding, the shut off pin will close the nozzle gate, to avoid gate vestige and waste material.

 

Compared with the common using mould, valve needle type hot runner cost is very high, and the hot half thickness, processing all will be rising. Though it will make the system be more complex but use this system can help to produce high quality product and solve the gate marks on the product s problem.

 

Valve gate hot runner advantage:

1.       save the processing cycle, improve the working efficiency.

2.       Due to replace the cold runner, do not produce runner material, no need to crush, can save a lot of raw materials. 

3.       Improve product consistency, no bump gate marks, completely eliminate the gate salivate, no wiredrawing phenomenon.

4.        Obviously improved the appearance of the product;

5.       Helps to reduce stress, To reduce the product caused by brittle deformation and structure

6.       So as to improve the production ability of complex structure of the product and the service life; 

7.       Not restricted by injection molding material replacement
