Machine Tool Manufacturer Streamlines with In-House Heat Treat

A machine tool manufacturer has decided to create their own “captive” heat treat department.  The company has consequently invested in two different, yet complementary, vacuum heat treatment furnaces.

As is often the case with companies thinking about how to gain better control of their production systems, one of the obvious bottlenecks for the customer was their offsite heat treatment arrangement. While quality from their existing suppliers was not an issue, it was clear that logistics could certainly be streamlined by eliminating the need to outsource parts to an external heat treater. The furnace manufacturer helped them weigh the pros and cons of moving their heat treatment processes into the plant. Ultimately, a decision was made to set up their own department, invest in new vacuum heat treat equipment, and train their production technicians to perform this critical function of the plant.

SECO/WARWICK received an order for a multi-chamber carburizing vacuum furnace with integral gas or oil quench, and a high pressure gas quench vacuum furnace capable of quench pressures up to 15-Bar.

“We knew the customer was already getting excellent quality from their supplier, so the question was ‘How can we make the process better?’” said Maciej Korecki, VP of Business Segment Vacuum Heat Treatment Furnaces at SECO/WARWICK. “Starting an in-house heat treat department requires some amount of risk tolerance by ownership, and they needed assurance that the return on production improvements would be worth the investment. [We have] the background to help make those determinations, and as a manufacturer of heat treat equipment, the company was able to offer real-world experience on performance that an independent consultant might not be able to provide.”
