Now we have understood the importance of mold design review, do you know how to start? Generally, The mold designer then uses the information gathered for him from the previous steps to generate a mold design and submit a tool assembly drawing to the mold buyer for approval. The next step is mold design review, [...]
Use of aluminum tooling has been an ongoing discussion for years, and the resulting flow of information has been a key part of aluminum’s growth as a mold material alternative. This continuous growth has led to advances in mold alloys, material size availability, mold design, finishing practices, coatings and welding techniques. More and more success [...]
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 is usually within the range of 30—42HRC, wherein the cutting property is not good under high hardness, […]
Some plastic mold steels after being processed and molded will deform dramatically during heat treatment, whereby the precision of molds cannot be ensured. […]
when molding plastics of particularly large abrasion force, the abrasion may still be rather serious even if high carbon or high chrome is used. […]
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. […]
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. […]
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, 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 [...]
