Filter for Hot Runner Injection Moulding Removes Melt Contaminants in Two Stages

Melt Design Inc., a manufacturer and global supplier of high-performance hot runner systems with a broad range of associated components, has added to its product line a dual-stage plastic-melt-filtering device designed to remove contaminants from the melt flow during injection moulding. The innovative device eliminates the need to clean out mould gates and saves further hours of production that might otherwise have been lost to material contamination. read...

Beryllium-Free Copper Mould Making Alloy Features High Strength, Thermal Conductivity

AMPCO Metal, an integrated producer and distributor of specialty copper alloys, employs proprietary manufacturing processes and complex alloy compositions to give its Ampcoloy® 944 copper-silicon-chromium alloy for mould making unique properties. Distinctive for being free of beryllium, this strong copper alloy offers mould makers an attractive balance of hardness (28 HRc on average) and thermal conductivity (156 W/mK, five to six times greater than P20 tool steel and six to seven times greater than H-13 tool steel), and an electrical conductivity of approximately 35% IACS. read...

Sheet-Steel Coating Delivers Cathodic Corrosion Protection for Hot Stamping

Just as galvanizing steel provides long-lasting corrosion protection for cold-formed automotive parts, the GammaProtect® electrolytic coating for steel to be hot-stamped yields an effective antirust finish that withstands the very high temperatures involved in hot stamping. The high-melting-point coating developed by ThyssenKrupp Steel protects against scaling and also prevents cathodic corrosion as actively as the galvanization process does for cold-forming steels. It expands the range of applications for hot stamping to include parts in the “wet” area of the car body. read...
