HOT-PLATE WELDING

Hot-plate welding is the process of welding two plastic parts together using a heated tooling plate. A weld rib or bead on each component is brought into contact with the hot plate. Heat conducts into the weld rib causing it to melt. The heated tool is then removed and the parts are pushed together until they bond to one another.

Melt

Two components are brought into contact with a heated tool. The heat conducts into melt ribs causing them to soften. Also called the ‘Heat Phase’.

Open

The components are removed from the heated tool and it is retracted out of the way. Also called the ‘Changeover Phase’.

Seal

The components are brought together and a hold pressure is applied until the weld cools. Also called the ‘Weld Phase’.

It’s not just about speed

Servo-controlled hot-plate welders eliminate the need for tool stops and provide true process control and speed.

Speaking of Force…

Get rid of the stops and start controlling the weld process by distance and force with velocity control.
