The VW-35/40/55/70 model bonds thermoplastic materials by transferring linear vibration energy to the upper and lower contact surfaces of the product under pressure, creating displacement friction. The resulting friction heat welds the product together seamlessly.
The welding process is divided into 4 stages.
- Phase 1
Initial Friction Phase
- Phase 2
Unstable Melt Phase
- Phase 3
Stable Melt Phase
- Stage 4
Solidification phase
