Thread Rolling
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. This results in an improved process:
- no burs, jagged edges or shavings
- faster cycle times and extended tool life with preheat step
- stronger and more fatigue-resistant threads
Thread Patching
Thread patching is a process of curing paint or powder coating that has been applied to a section of the fastener threads to prevent loosening of the fastener due to vibration. Induction provides an process for:
- superior cure for paint or powder coating to fastener treads
- highly localized heat directed only to the area that needs curing
- no lengthy warm up or cool down cycles
- faster production rates and higher yields
- parts can be individually monitored for quality
