Improved equipment lifetime through chromizing
High temperature engineering plastics containing glass fibers and flame retardants have the tendency to cause abrasive wear and corrosion on molding and extrusion equipment. This is not limited to the materials in the DSM portfolio.
Chromizing is a well-known, existing and commercially available surface treatment to improve wear and corrosion resistance for steel parts.
Successful trials with a treatment known as chromizing, clearly show a significant improvement in both abrasive wear and corrosion. The immediate effect is a longer life time for molding and extrusion screws including tips and check valves as well as other components like for instance nozzles, tips and needles of hot runner systems.
