To reduce wear of cores and cavities where enhanced release of molded parts is desirable. Also for reduced galling of non-molding tool surfaces. 0.000080" (2 microns) Virtually all of the commonly used materials for mold making, including all non-leaded or sulphurized steels, stainless steels, plus beryllium copper, and aluminum. Substrates must be free from previous coatings such as titanium nitride, chrome, TeflonŽ, black oxide, electroless nickel, and the like*. PVD-102 Boron carbide sputtered in vacuum at less than 250°F. To reduce wear of cores and cavities when release or corrosion are not issues. 0.000080" PVD-103 Chrome & boron carbide layers sputtered sequentially in vacuum at less than 250°F. To reduce wear of molding surfaces when corrosion is also a problem. 0.00010" PVD-104 Chrome & boron carbide layers sputtered sequentially and blended in vacuum at less than 250°F with tungsten disulfide impinged into the surface. To reduce wear and corrosion when molding filled resins where inadequate release is also a problem. 0.00010" * Many coatings can be removed at our facility. Call for more information. Photomicrograph of PVD-104 coating structure. In this photomicrograph of a PVD-104 coating, a clean mold surface is coated with a layer of chrome for corrosion resistance. Next, the boron carbide is applied in a very tightly packed columnar structure for wear resistance. To improve release, a layer of tungsten disulfide is then impinged into the surace. The result is a hard, smooth, lubricious ceramic film that delivers outstanding mold performance.
