What are the technical requirements when making injection molding machine templates?
High toughness, high rigidity ZG35, ZG40 steel or ductile iron should be selected for the manufacture of the template.
Parliamentary casting billets should be annealed first to eliminate casting stress.
When machining, divide the rough and precision cutting twice.This part of the process is best conducted on boring machine, a clamping, at the same time completed four rod holes, working face, the center hole and so on various parts of the processing surface, to ensure that the four hole centerline and templates work flat vertical accuracy requirement and accuracy requirement and the center line of the template symmetry.
The roughness Ra of the workplane machined planes shall not be greater than 1.25 degrees Celsius.
