Weld plastic parts together

If you want to join several plastic parts together, you can join them together at the joint surfaces with a simple soldering iron. It's quick and you don't need any additional material. ♻️👌

1 Choose your soldering tip

A very stable connection is created when the connection surfaces are first welded deeper and then at the edge. For the deeper welding, a thin soldering tip is suitable and for the edge seam a larger one.

2 Choose the welding temperature

Do some temperature tests. I use around 250 ° C for HDPE and 270 ° C for PP. Please use a gas mask for this work! See also: https://community.preciousplastic.com/academy/plastic/safety

3 Weld it

Position the parts and fix / clamp them. Weld the parts first with the thin soldering tip and then with the thick soldering tip. Not too fast! Check the connection and change the parameters: temperature, welding depth and speed if necessary. Happy melting!

4 How to make the lamps

The recycling guy in this video shows how he combines 12 plates to one hanging lamp ;) In addition to HDPE, you can also use this welding technique with PP. LDPE or PS. After welding, you can also improve the edges. I rub with additional hard plastic over the edges, but you can also polish.
