About Induction
While gas furnaces and flames have been used for centuries to pre-heat metal for hot working, these methods have become cost- and time-prohibitive. Induction heat benefits fastener manufacturers by delivering heating that:
- is reliable, repeatable and energy-efficient
- is responsive and non-contacting
- is integratable through the use of a remote heat station
- improves production rates with minimal defects
- Hot Forming
- Hot Heading
- Forging
- Zone Annealing
- Rolling, Patching
Hot forming is a process in the manufacture of industrial fasteners such as bolts, screws and rivets. Heat is used to soften the metal which is usually a sheet, bar, tube or wire...[more]
Induction heat is used for preheating bolt heads prior to forming bolt and screw heads, lips on plates, hollow parts, fabrication of nuts from a titanium, inconel (nickel alloy) or stainless steel slug. [more]
Forging is a method of plastically deforming a metal accomplished by hammering on a single piece of metal. One method involves a force which is brought to bear down on two die halves having the finished shape such that the metal is deformed in the cavity between them. [more]
Annealing is used to soften a section of the fastener, reducing brittleness...[more]
Rolling a thread into a heated fastener (instead of milling or grinding the thread) has many advantages. We have developed a specially-designed heat station for this application which can be vertically clamped to the thread-rolling machine and then easily adjusted to match the length of the fastener material being heated.
