Applications
Tube Bending


- Provides high-quality surface finish with easy set-up.
- Minimum friction making it easy to regrind.
- No seizing, scratching or corrosion starting point.
- Improves sliding properties.
- Reduce cost and extend life.
Knowing that certain applications require unparalleled quality and production tool longevity, we developed AMPCO®18, AMPCO®18.23, AMPCO®21, AMPCO®22 and AMPCO®M4. Specifically for tube bending of stainless steel and titanium material exhaust pipes, these engineered materials are able to form from both sides, delivering tighter roundness tolerance and all-round product efficacy.
Advantages of AMPCO®21 and AMPCO®22 mandrels and balls:
- Extended life
- No hardening or expensive coatings on the mandrel required
- No galling
Advantages of AMPCO®18, AMPCO®18.23 and AMPCO®M4 wiper dies:
- Extended life (20 times longer with AMPCO®M4)
- Easy set-up
- No galling
- No scratching
- No corrosion starting point
- This type of end formed tooling supports material forming from both sides to deliver tighter roundness tolerances for joining or welding
Advantages:
- Provides high quality surface finish
- Form non-symmetrical and symmetrical shapes
- Easy to regrind
