A Pulse Heat Staking Welding Machine is an intelligent assembly system that utilizes pulse-based precision temperature control to locally heat and form plastic rivet posts, enabling high-strength, low-deformation, and highly consistent plastic joining processes. It is widely used in the manufacturing of automotive interior and exterior components, as well as precision plastic assemblies.
A pulse heating staking unit is equipped with a generator similar like ultrasonic welding generator, the pulse head’s temperature can be up to 300℃ just 10 seconds, after the welding points are welded by pulse heat staking units,the heat staking unit will stop heating up, and then the heat staking welding unit is also equipped with a cooling air tube to cool the welding points down.
This kind of pulse heating staking welding machine is very good for welding automotive lighting: more precise welding, better welding strength.
Difference Between Traditional Heat Staking and Pulse Heat Staking Machine
| Comparison | Traditional Heat Staking Machine | Pulse Heat Staking Machine |
|---|---|---|
| Heating Method | Continuous heating | Instant pulse heating |
| Temperature Control | Standard | Highly precise |
| Appearance Quality | Prone to yellowing and stringing | Cleaner and more aesthetic |
| Energy Consumption | Higher | Lower |
| Cycle Time | Standard | Faster |
| Process Stability | Moderate | Higher stability |
| Suitability for Precision Parts | Higher risk of deformation | More suitable for precision components |
