Evaporation Boats
HMT provides innovative, performant and economical evaporation boats for packaging and capacitor film metallizing as well as crucibles for special PVD applications. HMT evaporation boats allow high evaporation rates and easy operation while reducing the total metallizing cost.
HMT manufactures 3-component evaporation boats from boron nitride (BN), titanium diboride (TiB2) and aluminium nitride (AIN). Due to their superior initial wetting behaviour, HMT evaporation boats allow extremely easy handling while being compatible with all vacuum coaters in operation at an evaporation rate of up to 0,35/(min*cm2). That perfectly fits all metallizing processes while guaranteeing easiest control of operational parameters.
HMT provides boats for all customized and special metallizing purposes. Based on cutting edge material recipings and specific designs developed by our metallizing experts, our boats, made custom-tailored for your specific needs including resistivities, optical densities/evaporation rates and web speeds, serve as the ideal solution for metallic yarn, OLED substrates, antistatic and solar films metallizing.
With a unique design free of cavity, HMT’s specially designed evaporation boats reach highest wetting ratios on their functional surfaces, so become the most economical product in our range through drastically reducing the direct metallizing cost and subsequent recycling charges.
