Welding Machines

Not only the welding of plastic materials environmentally safer than bonding techniques using adhesives, it is also more cost-efficient. An additive is omitted. The specific challenge posed by the development of welding machines for all industries is the presence of heat and therefore expansion. This applies to small manual devices as well as machines and large-scale systems. Whenever plastic components are subject to mechanical or thermal stresses, welding is the safest – and sometimes only – method to securely join the individual parts. The welding of plastic pipes enables drains to withstand pressures of up to 10 bar (or greater), while engine parts in passenger cars and trucks can now be exposed to heat without any problems. We offer you qualified advice and professional realization for tools and machines you need for plastics of all kinds. To show you the various plastic welding techniques we briefly explain three of them in the table below.

Heated Tool Welding
Butt welding, welding by bending, sleeve welding with appropriate heated tool.

Friction Welding
Using heat generated through mechanical friction between moving work pieces, thereby joining parts to be welded. Through a heating element two plastic parts are heated and assembled afterwards.

Radiant heat sealing
(Infrared) noncontact welding through the use of radiation sources in different wavelength ranges. High temperatures are reached. Infrared welding is a non-contact welding. Because of the possible high heating temperatures the method is very suitable for high-performance plastics. Temperatures up to 600° are possible.
