The lead angle of your cutter has a dramatic effect on not only the chip that you generate, but also the cutting forces in both the axial and the radial directions. All of this can affect your overall productivity. There are many milling lead angle concepts on the market today and each is designed to [...]
Much has been written and discussed relative to the cooling of mold cavities. Most molders and moldmakers are at least aware of the benefits of placing as much heat removal technology into a mold core or cavity as possible. Simply drilling a hole into the bottom of a core for a closure and inserting a [...]
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 [...]
