CNC technology is complex and there are many influencing factors. It is necessary to think deeply about the whole process of CNC Machining. It has good strip rationality and can program CNC technology well. CNC machining has a high degree of automation and poor adaptability. When problems occur, it is difficult for operators to correct them on the spot. Light-weight personnel create machining defects. When a safety accident occurs in the middle, CNC technology should be systematically designed in advance. CNC machining should ensure the accuracy and surface roughness of the workpiece to be machined.

What are the most important part of CNC machining of plastic molds?

Plastic mold core refers to the Precision Machined parts used for key operations in the center of the mold. The mold core is generally complex in structure, very difficult to process, and expensive to manufacture, and the labor cost of manufacturing often exceeds the material itself.

When the male mold core is processed, first use a grinder to leave a margin around the mold core and thickness, and then fine-grind after quenching. Heat treatment with complex shapes can be performed by high frequency heat treatment or vacuum heat treatment or carburizing heat treatment, and the deformation of these heat treatments is very small. In fact, the deformation of heat treatment is also related to the placement of the Plastic Part during heat treatment. Improving the placement form can also greatly reduce the deformation. In addition, your grinder can also grind flat surfaces.

The upper surface of the mold core is a complex shape, suck the complex shape to smooth the bottom surface, the most stupid way is to use three adjustable support points, find three points on the complex cavity surface, level the bottom surface, and then Use two flat blocks on the left and right (the height of the flat block is lower than the bottom surface, clamp it. Then CNC Grinding Processing the Plastic Machining Parts .

The choice of mold core material is directly related to the cost of the plastic mold and the service life of the mold.

The rapid development of CNC machining and production of plastic molds is mainly due to the innovation and transformation of Cnc Milling Service technology. From the traditional general CNC lathe to the three-axis machining management center, and then to the previous five-axis high-speed milling, the processing of complex three-dimensional profile parts can be idealized, and the strength of the material is no longer a limitation. problem. The key concave molds and profiles of Plastic Injection molds are processed by CNC milling.
