There are two main purposes for polishing the mold. One is to increase the brightness and beauty of the plastic mold. The second is to make the mold easy to demold. When polishing, generally use a coarse whetstone to roughen the surface of the machined mold cavity, and then grind away the marks of t... read more
Since the mold is developing in the direction of large-scale, molds of several tons to tens of tons are very common, so the worktable of the machine tool is required to bear a large weight, which requires the equipment to have the characteristics of large load-bearing and high rigidity. 1. The multi... read more
1. Good thermal stability The shape of plastic injection mold parts is often more complicated and difficult to process after quenching, so it should be selected as far as possible with good thermal stability. When the mold forming process is heat treated, the linear expansion coefficient is small, t... read more
1) When a new mold cavity starts to be processed, the surface of the work piece should be inspected first, and the surface should be cleaned with kerosene so that the oil stone surface will not stick to dirt and lose its cutting function. 2) When researching coarse grains, the order of difficulty is... read more
Plastic mold plating is usually carried out by multilayer plating. If the operation is not strict, poor adhesion may occur, such as blistering and peeling of the coating. The reason is not only the following three main types of influence. (1) Influence of electroplating process: improper combination... read more
