Sprue Sleeve

Product Description & Drawing

Sprue Bush is one of CNC metal parts of the plastic mold used to connect the forming mold and the plastic injection molding machine. It can also be described as a part where the molten plastic material is injected from the nozzle of an injection moulding machine into the runner inside the mold.
If the contact part of the sprue bush is not machined accurately enough, it may leak plastic material when combined with the injection moulding machine. If the sprue bush is not hard enough, the nozzle contact part will be more vulnerable to wear. During the demoulding process, if the runner inside of the sprue bush is not smooth enough, it will lead to bad stripping, so you have to choose the high-quality sprue bush.
Sprue Bushes is available in a number of specifications. Please give us your drawings, and we will process and customize them..
