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.

Step 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.

Step 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!

Step 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!

Step 4 - How to make the lamps

The recycling guy in this video shows how he combines 12 plates to one hanging lamp :wink:

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.
