B Type Mould Sprue Bushing for Injection Mould
Description
The sprue sleeve is a part that allows molten plastic raw materials to be injected into the inner runner of the mold from the nozzle of the injection molding machine. If the nozzle contact part of the sprue sleeve is not machined with high precision to match the spherical surface at the front end of the nozzle of the injection molding machine, plastic raw materials will leak out during injection molding. In addition, if the sprue sleeve does not reach enough hardness, the nozzle contact part will be worn in repeated contact during injection molding. The sprue sleeve should be selected according to the types of plastic raw materials and the expected forming conditions. In addition, the inner surface of the hole for the runner should be machined into a good surface roughness to avoid the inverted shape. If the surface roughness is poor, it may lead to poor demoulding of the runner during forming.

If the quality of sprue sleeve is different, the flow rate and molding conditions of plastic raw materials will change, and it is difficult to carry out unified quality management of mold. GEPE's sprue sleeve has good quality assurance, so it can avoid the above phenomenon.
