what is the BOM in a mold enterprise ?
the BOM table takes mold products as the unit, namely, mold products recorded in the same BOM table are of the same serial No, and are distinguished by material No, […]
introduction to mold material flow
Generally, when the number of staff of a mold manufacturing enterprise reaches 100, a network collaborative mold manufacturing system shall be required, wherein the management of mold materials is one of the most essential parts. […]
mold parts and mold steel
mold parts without special requirements can be manufactured from carbon structure steel( such as Japan’s S45C, S50C, and S55C) or carbon tool steel(such as Japan’s SK series), […]
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 [...]
