Technical processing of plastic components
Bending, welding and bonding
Welding
Welding is accomplished with a hot air heat gun and added material (filler wire). Extruder welding is also carried out with a filler metal which is melted.
Welding can be made in these materials:
- PVC
- PC
- PP
- PEHD500 (extruder welding)
Bonding
Bonding is made primarily where there is a desire not to make a mechanical action on the item’s appearance.
Bonding can be made in these materials:
- PVC
- PC
- Acrylic
- PETG
Bending
OTV has expertise in both cold and hot bending in high quality. The table below shows which materials can be bent and in which thickness.
Processing – Bending/bonding/welding
| PMMA | PC | PVC | PETG | PP | PEHD<500 | |
|---|---|---|---|---|---|---|
| Hot bending max. sheet length (mm) | 1500 | 1500 | 1500 | 1500 | 1500 | 1500 |
| Hot bending max. sheet thickness (mm) | 10 | 10 | 10 | 10 | 10 | 10 |
| Cold bending max. sheet length (mm) | n/a | 3000 | n/a | 3000 | n/a | n/a |
| Cold bending max. sheet thickness (mm) | n/a | 5 | n/a | 6 | n/a | n/a |
| Bonding (type of glue) | Acrifix | Ruderer | Tangit | Ruderer | n/a | n/a |
| Welding (*extruder) | n/a | Hot air | Hot air* | Hot air | Hot air* | Hot air* |
When hot bending of material over 5 mm processed material. (There is milled a trace)
