We believe that any injection molding feedscrew that is replaced or rebuilt at 24 months or less will benefit significantly from encapsulation with carbide. Extrusion feedscrew that are rebuilt or replaced within five years will likewise see great benefit from carbide. Obvious gains are longer screw life, however intangible benefits such as consistent quality, through-put, lower energy and maintenance costs, as well as higher capacity utilization offer cost savings and competitive advantage.
