Plastic Welding (Hot plate or Ultrasound)

China Synergy offers two kinds of plastic welding techniques to manufacture your products.
Hot Plate Welding | Ultrasound Welding

Hot Plate Plastic Welding

In the “hot plate” process, plastic workpieces are heated (surface melted) by mold (hot plate) then joined together. You can get a better understanding by watching our production video below.

Benefit of Hot Plate Plastic Welding

1.No size limitation, comparing to ultrasound welding’s inability to weld large products.

2.No material limitation. For example, ultrasound welding doesn’t work with pure PP, while hot plate can.

3.Solves fusion welding problem for large, curved and thick-walled plastics.

4.Working in conjunction with injection molding, you can make very complex product shape.

5.Airtightness, water tightness and tensile strength of the products can be assured.

6.Comparing to gluing, plastic welding means high production efficiency, no deformation, no pollution, and firm welding.
