As most of the working conditions of precision plastic mold is very bad, and some often bear a greater impact load, resulting in brittle fracture. So in order to mold parts in the work suddenly brittle broken, precision plastic mold processing materials to have a high strength and toughness.


Mold development factory pointed out that in the precision plastic mold processing process, the choice of materials as the basis of the entire process is very critical, on the one hand to meet the requirements of the actual working conditions, on the other hand to achieve the performance requirements, of course, not Ignoring the economic requirements.


When the blank in the precision plastic mold cavity plastic degeneration, along the cavity surface both flow and slide, so that the cavity surface and the billet produced a serious friction between, resulting in precision plastic mold due to wear and failure. So the precision plastic mold processing materials is one of the basic properties of wear resistance.
Precision plastic mold work in the process, the long-term role in the cyclic stress, often lead to fatigue fracture. Mold development factory pointed out, but if its processing materials, fatigue fracture performance is better, then this problem will be greatly improved. In addition, high temperature, cold and heat fatigue resistance, corrosion resistance, etc. are also included in the actual working conditions.
Mold development factory pointed out that in the process performance, precision plastic mold processing materials need to meet the malleable, annealing process, cutting, oxidation, decarburization sensitivity, hardenability, hardenability, quenching deformation cracking tendency and Grinding and so on.
In the precision plastic mold processing, precision molds processing materials, we must consider the principle of economy, as much as possible to reduce manufacturing costs. Therefore, to meet the use of performance under the premise of the first choice of lower prices, can use carbon steel without alloy steel, can use domestic materials do not have imported materials.
