Chemical vapor deposition allows ultra-thin lubricious coating for mold components


A chance meeting at a trade show has brought a coating technology that originated in the semiconductor industry into injection molding, giving mold components an inert, lubricious coating that eliminates the need for grease in medical and packaging applications, among others.

The Poco Graphite technology, marketed to the injection molding industry by PCS Co. as UltraC coatings, creates what the companies call diamond-like carbon (DLC) coatings that reportedly enhance durability and mold productivity while reducing friction and corrosion.
