The characteristics of mold processing

date：2023/08/10

Mold processing industry, in the global market seems to account for a large share, if careful analysis can be found, China's mold processing technology is low, for high-end market, the lack of considerable strength and competitiveness. The mold manufacturers today with you talk about the characteristics of China's mold processing.

(1) processing accuracy requirements of a pair of molds are generally by the die, punch and mold frame, and some may also be more than a split module. So the combination of the upper and lower molds, the combination of inserts and cavities, the splicing between the modules requires a high degree of machining accuracy. Precision mold size accuracy is often up to m level.
(2) complex surface Some products such as automotive panels, aircraft parts, toys, household appliances, the shape of the surface is a combination of a variety of surfaces, so the mold cavity surface is very complex. Some surfaces must be processed by mathematical methods.
(3) the production of small batch mold is not mass production in batches, in many cases often only produce a pair.
(4) process multi-die processing always used milling, boring, drilling, hinge and tapping and other processes.
(5) repeat the use of mold production is life-long. When the use of a pair of mold over its life, it is necessary to replace the new mold, so the mold production is often repeatable.
(6) copy processing mold production sometimes no pattern, there is no data, but also according to the physical copy processing. This requires high imitation precision, no deformation.
(7) mold material is excellent, high hardness of the main mold material used in high-quality alloy steel, especially high-life mold, often used Crl2, CrWMn and other products made of Lattice. This type of steel from the rough forging, processing to heat treatment are strict requirements. So the preparation of processing technology can not be ignored, heat treatment deformation is also the need to seriously deal with the problem.
