Hardening surgical blades

To quickly heat a steel surgical blade to 2000°F (1093°C) within 2 seconds so as to harden the blade edge.

Hardening Seat Belt Parts

A four-turn helical concentrating coil is specially designed to deliver uniform heat to the steel seat belt retraction gear.

Hardening the teeth of a large saw blade

A torch isn't as precise as induction nor is it repeatable; induction heating is highly repeatable, uses less energy than a torch and offers instant on/off heating

Case hardening a steel fitting (machined parts manufacturer)

The coil design enabled the part to be raised into the heating coilfrom the bottom. The design was also made to ensure it will work well within the customer's current setup...

Surface hardening of steel screws

Induction heating enables precise application of heat, faster process time and production rates and the ability to be incorporated into existing production lines

Hardening teeth on a steel motorcycle gear

A single turn helical coil is used to heat the gear. The gear is placed on a spindle and rotated at 300-350 RPM's.

Hardening steel screw threads

A five turn helical coil is used heat the screw threads. The screw is placed in the coil, heat is applied for 8 seconds to achieve a 2 long zone at the required hardness.

Hardening the end of steel hand-held marking stamps

To harden various size ends of hand held marking stamps. The area to be hardened is 3/4 (19mm) up the shank.

Hardening of Steel Cam Assembly

Hardening the cam outer surfaces with induction results in uniform heating for uniform results, one coil can be used for many geometries, consistent results from piece to piece

Case Hardening of Armature Shaft

A five turn helical coil is used to heat the gear end of the shaft to 1700°F

Hardening Cast Iron Pulleys

Heat cast iron pulleys to 1600°F(871.1°C) in order to achieve a hardness of 55 Rockwell C.

Hardening Stainless Steel Surgical Knife Blades

A two turn helical coil with an internal quartz tube designed to scan the length of the blade is used to heat the blade to 1850°F (1010°C) to achieve the desired hardness.

Hardening Bed Knife Blade for Reel Type Lawn Mowers

The hardness desired is between 45 to 55 Rockwell C, and should be measured 0.062"(1.6mm) from the cutting edge.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
