the service hardness of pre-hardened steel
the service hardness of pre-hardened steel is usually within the range of 30—42HRC, wherein the cutting property is not good under high hardness, […]
Pre-hardened plastic mold steel
Some plastic mold steels after being processed and molded will deform dramatically during heat treatment, whereby the precision of molds cannot be ensured. […]
about molding plastics of particularly large abrasion force
when molding plastics of particularly large abrasion force, the abrasion may still be rather serious even if high carbon or high chrome is used. […]
all erosion-resistant steels have sufficient abrasion resistance
generally , all erosion-resistant steels have sufficient abrasion resistance which can be improved through surface treatment, such nitriding, although it can reduce the erosion resistance property. […]
introduction to through-hardened plastic mold steel
Compared with casehardened steel, the outstanding merit of through-hardened steel is that the heat treatment thereof is simple, wherein extra heat treatment can be re-made during subsequent mold repair process. It’s demerit is that crackles can easily occur, especially for large-scale molds. […]
introduction to casehardened steel
Casehardened steel can be provide with tough core and abrasion-resistant surface, wherein high surface hardness will be beneficial for polishing treatment. […]
plastic mold parts fall into working parts and structural parts
plastic mold parts fall into working parts and structural parts, working refer to those determining the geometrical shape, dimension and precision of plastic products, and are also called molding parts or the molding section of parts, such as cavity, core, insert, molding pin and molding ring etc, their molding condition is rather complicated and the [...]
basic requirements for the performance of plastic mold steel-2
Certain heat resistance and erosion resistance. Due to the generally complicated structure of plastic molds, it requires low surface roughness and high precision for the cavity and excellent technical performance should be ensured. The specific requirement is as follows: […]
basic requirements for the performance of plastic mold steel-1
When a mold designer designs a mold, he or she needs to choose correct mold steel for the mold, so the mold designer need to know some basic requirements for the performance of plastic mold steel: […]
how to choose correct mold materials
Plastic mold is of multiplex varieties and specification. Due to it’s complicated shapes and low surface roughness, it is rather difficult to be manufactured. […]
