Temperatures for welding plastic
Pay attention to the correct temperature when welding plastic.
Select the temperature so that the plastic melts slowly and work at a moderate speed.
Too high temperatures can damage the plastic and lead to unreliable welding.
Feel free to follow our recommendation on temperatures to achieve satisfactory and reliable results.
Welding temperatures when using a welding piston, a hot air blower and an Injectiweld or extruder:
