The midwest’s premier provider of CrN, TiN and ZrN coatings for Plastic Injection Molds.
North Star Coating offers highly wear resistant coatings for injection molding of both metal and plastics. These PVD coatings also offer a significant advantage when it comes to mold release. With the ever increasing presence of glass filled and carbon filled plastics that wreak havoc on molds and mold components, a thin layer of PVD coating is the solution. A coating like TiN (Titanium Nitride) is a great color indicator so you know when the mold is starting to wear.
