| Heat Staking |
GENERAL DESCRIPTION:
Thermal staking is an assembly method that uses the controlled melting and reforming of a plastic stud or boss to capture
or lock another plastic or metal component of an assembly in place. The plastic stud protrudes through a hole in the component to be locked in place. The heated thermal tip contacts the top of
the stud, which melts and fills
the volume of the tip cavity to produce a head, locking the component in
place. The progressive melting of plastic under continuous pressure
forms the head. When staking, the right combination of heat and pressure
for the application is critical.
ADVANTAGES:
• Simplification of machinery
• Reduced cost of machinery
• Multiple fastening points
• Allows higher density of welds compared to hot air cold form or
ultrasonic welding
• Many different size or shaped heads can be formed |
