Plastic mold processing refers to the processing of plastic molding and plastic billet tools, there are two parts of the upper mold and the lower mold, its basic features are as follows:

(1) high precision machining A die is generally composed of die, punch and die form, and some may also be more pieces of modular. So the combination of the upper mold and the lower mold, the combination of the insert block and the cavity and the assembly between the modules all require a high processing precision. Precision precision mold size is often up to μm level.

(2) complex surface Some products such as car covers, aircraft parts, toys, household appliances, the shape of the surface is a combination of a variety of curved surfaces, so the mold cavity surface is very complicated. Some surfaces must be mathematically calculated.

(3) The production of small batch molds is not mass-produced in large batches, and in many cases often only one payout is made.

(4) Process Multi-mold machining always use milling, boring, drilling, reaming and tapping and other processes.

(5) repetitive production of mold use is life. When a pair of molds are used more than their lifetimes, new molds are replaced, so mold production tends to be repetitive.

(6) profile processing Sometimes there is no pattern in the production of molds, there is no data, but also according to the actual shape processing. This requires high precision imitation, no deformation.

(7) excellent mold material, high hardness The main material used in the mold made of high quality alloy steel, especially high-life mold, often used Crl2, CrWMn and other martensitic steel. Such steel from rough forging, processing to heat treatment has strict requirements. Therefore, the preparation of the processing technology more can not be ignored, heat treatment deformation is also the need to be taken seriously in the process of processing.

Understand the basic characteristics of plastic mold processing, machine tools used in the selection to meet the processing requirements as much as possible. Such as CNC system features a stronger machine to high precision, rigidity is better, thermal stability is better, with profiling capabilities.
