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
