Mold manufacturing all kinds of tools and products used in our daily production and life, ranging from the base of the machine tool and the shell of the machine body to the shell of a blank head screw, buttons and various household appliances, all are closely related to the mold.
The shape of the mold determines the shape of these products, and the processing quality and precision of the mold also determine the quality of these products.
Because of the different materials, appearance, specifications and uses of various products, the molds are divided into casting molds, forging molds, die casting molds, stamping molds, and injection molds.
The general definition of mould: in industrial production, parts or products made of metal or non-metal materials are pressed by various presses and special tools installed on the presses, this special tool is commonly known as a mold.
A set of injection mold is composed of many parts. The quality of the parts directly affects the quality of the injection mold, and the final quality of the parts is guaranteed by finishing, therefore, it is important to control the finishing process.
In most domestic mold manufacturing enterprises, the methods used in the finishing stage are generally grinding, electric machining and bench work.
At this stage, many technical parameters such as deformation, internal stress, shape tolerance and dimensional accuracy of parts should be well controlled. In specific production practice, operation is more difficult.
The processing of mold parts can be roughly divided into three categories according to the different appearance and shape of the parts: plates, special-shaped parts and shafts. The common technological process is roughly as follows: rough machining, heat treatment, fine grinding, electric machining, fitter (Surface Treatment), Assembly processing.
Our NJPE has seven categories of precision processing equipment, CNC equipment, precision grinding machine equipment, WEDM equipment, EDM equipment, testing equipment, trial production equipment and other equipment.
There are still many factors related to the quality of injection molds. If you want to know more about it, you can click on the online customer service consultation on the right or call NJPE hotline: 4008-378-078!
