Oerlikon Balzers has introduced BALINIT ARCTIC: a new low-temperature line of PVD coatings for molds and components. "An innovative arc technology allows BALINIT ARCTIC Coatings to be applied at 200¡C (390¡F), substantially lower than standard PVD coatings that are applied between 400 and 500¡C (750 to 930¡F)," said a company spokesperson. "This makes it possible to coat cold-working steels and die steels for plastics processing that are commonly tempered at 200¡C, as well as copper alloys.
"BALINIT ARCTIC PVD coatings have no performance loss compared to coatings deposited at higher temperatures. The lower deposition temperature allows mold materials with lower tempering thresholds to be coated without distortion, loss of hardness, or reduction in corrosion resistance.
"There are three BALINIT ARCTIC coating versions:
BALINIT A ARCTIC (TiN) has a surface hardness of 2300HV and a coefficient of friction against steel of 0.4, which helps to prevent the buildup of resins, increases wear-resistance and provides a surface that is easier to clean.
BALINIT D ARCTIC (CrN) has a surface hardness of 1750HV and a coefficient of friction against steel of 0.5, and is well suited for coating molds that work in plastics that outgas chlorine, fluorine or other aggressive volatile contents during processing.
BALINIT FUTURA NANO ARCTIC (TiAlN) is a nano-layered coating that has a surface hardness of 3300HV and a coefficient of friction against steel of 0.5, and is ideal for plastic injection molds with textured surfaces and for working in engineered plastics."
