Heat treatment is the process that will either make or break a company’s reputation. Much of a roller chain’s performance is determined by the care and attention the components are given throughout heat treatment and metal finishing. It is no surprise then that we tend these areas with a great deal of attention and control them with care. The heat treatment area consists of two belt furnaces which are used exclusively for through hardening and tempering plates, and three box and one rotary furnace that are used for a combination of case or through hardening of our round parts. All our components are oil quenched and the processes are closely monitored by computerized controls that ensure all critical variables are maintained within our strict specifications.

Metal finishing , although not as complex as heat treatment, is equally as important to the performance of the product. In this area we have three shot peening machines. Several specialized finishing processes allow us to modify surface finishes with a variety of abrasives and steel shot that enhance our products’ wear and fatigue life.
