1. The characteristics of plastic mold processing are as follows:

(1) High precision requirements for plastic mold processing

A mold is generally composed of a concave mold, a convex mold and a mold base, and some may also be a multi-piece split module.

Therefore, the combination of upper and lower molds, the combination of inserts and cavities, and the assembly of modules require high machining accuracy. The dimensional accuracy of precision molds is often up to m level.

(2) Plastic mold processing has complex shapes

For some products, such as medical injection molded parts, cosmetic packaging materials, toys, and household appliances, the shape of the surface is composed of multiple curved surfaces. Therefore, the mold cavity surface is very complicated. Some curved surfaces must be processed by mathematical calculation methods.

(3) Many plastic mold processing procedures

Many processes such as milling, boring, drilling, reaming and tapping are always used in mold processing, and mold saving and testing are required later, so the professional requirements of personnel are high.

(4) Repeated production

The use of molds has a long life. When the use of the mold exceeds its life, it is necessary to replace the new mold, so the production of the mold is often repetitive.

(5) Profiling

Sometimes there is neither pattern nor data in mold production, and it is necessary to perform profiling processing according to the actual object. This requires high precision in processing and imitation of plastic molds without deformation.

(6) Excellent mold material and high hardness

The main material of the mold is mostly made of high-quality alloy steel, especially the mold with a long life. This kind of steel has strict requirements from blank forging, processing to heat treatment. Therefore, the preparation of plastic mold processing technology cannot be ignored, and heat treatment deformation is also a problem that needs to be taken seriously in processing.

2. Plastic mold processing should meet the processing requirements as much as possible in the selection of factories, and inspect from multiple angles of equipment, personnel, scale, etc. In addition, the CNC system should have strong functions, high precision of the machine tool, good rigidity, and good thermal stability. Profiling function, etc. Only when the conditions are met in multiple directions can there be no worries.
