Hot Air Plastic Weld

With a very precisely regulated stream of hot air or gas exiting the tip, and proper control of the filler rod, the materials can be fused together to create a join as strong as the parent material itself.

This method usually uses a filler rod between 3 & 5mm in thickness although welding strap as wide as 10 to 15mm can be used with the correct tip fitted to the welder.

With proper technique this method of welding plastic is very successful though for some products and purposes, extrusion welding is superior.

Most filler rod is about 4mm thick, so it can take several passes with the welder to produce what an extrusion welder can do in one pass. Ideally suited to materials up to 6mm in thickness and general repairs, this is the method most used at CV Plastics.

For superior welding strength we use a Nitrogen mix of gases through the hand held plastic welder instead of the more common practise of using ordinary air. We have found the extra cost in setting this up is well worth the difference in the resulting welds.

We offer this service to all our customers at no extra cost.
