This is also a common question. After we improve feedscrew life, processors find a downstream component, profile die, calibrator, non-return valve, or other part that wears “quickly”. We have tried to solve a lot of these issues with thermal spray coatings and have learned that some respond well, others not. For inside diameter surfaces we offer our NiBoride nickel boride material. Click here for more details. . For non-return valves – tip assemblies, we have developed the Cushion Master. This is a solid tungsten carbide check ring and rear seat that provides from six to eight times the life of standard tip assemblies. Click here for more details.
