Here's How We Can Meet Your Surface Hardening Needs

We offer progressive, spin, and progressive spin flame hardening, which provide quick, economical and selective hardening of your parts to ensure increased wear resistance and longer life.  We have the latest temperature measuring equipment and five large ovens that are capable of heating / stress relieving parts up to 1,250ºF. These ovens, coupled with digital recording technology, ensure complete accuracy and traceability.

Our computerized robotic surface hardening systems have revolutionized the surface hardening industry! Our advanced robots, coupled with programmable index tables, provide an automation system that helps decrease production time while maintaining the highest quality in precision surface hardening. Typical applications include rings, complex gears, bearing assembiles and high volume production orders.

Penna Flame brings you a new generation of robotic induction surface hardening applications that utilizes the principle of electromagnetic induction to heat the surface layer of a part and harden it to your specific requirements. This new process enables us to handle larger volume runs faster and more cost-effectively than ever before and you get the same precision and reliabilty as with our other flame hardening processes!

Penna Flame's manufacturing division can meet your roll processing needs, as well as other types of precisely machined and tooled parts and supplies. When you combine this capability with our heat treating applications, you get a complete end-to-end process that can save you time and money by having it completed at one time and in one location. We're committed to reliability, dependability, and personalized service from beginning to end.
