Molds for metal and plastic mold processing are various molds and tools used in industrial production to obtain the required products through injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, and other methods. In short, a mold is a tool used to shape objects, which is composed of various parts, and different molds are composed of different parts. It mainly achieves the processing of the shape of the object by changing the physical state of the formed material. Known as the 'Mother of Industry'.

Hardware and plastic mold processing is a tool that transforms raw materials into parts with specific shapes and sizes under external forces. Widely used in punching, forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, as well as in the molding or injection molding of engineering plastics, rubber, ceramics and other products. The mold has a specific contour or inner cavity shape, and using a contour shape with a cutting edge can cause the blank to separate (punch) according to the contour line shape. The application of inner cavity shape can enable the blank to obtain a corresponding three-dimensional shape. A mold generally consists of two parts: a moving mold and a fixed mold (or a convex mold and a concave mold), which can be separated or combined. Remove the parts when separated, and inject the blank into the mold cavity to form when closed. Molds are precision tools with complex shapes that can withstand the swelling force of raw materials. They have high requirements for structural strength, stiffness, surface hardness, surface roughness, and processing accuracy. The development level of mold production is one of the important indicators of the level of mechanical manufacturing.

In addition to the mold itself, the mold for metal and plastic mold processing also requires a mold base, mold frame, mold core, and a device for ejecting the workpiece. These components are generally made into universal types. Mold enterprises need to become bigger and more refined. They need to determine product positioning and market positioning based on market demand, technology, funding, equipment, and other conditions. These practices are particularly worth learning and referencing for small mold enterprises, and focus on gradually forming their own technological and product advantages. Therefore, Chinese mold companies must actively strive to learn from the experience of these advanced foreign enterprises in order to achieve better development in the future.
