CNC Tube Bending Services

What is CNC Tube Bending?

CNC tube bending uses computer-controlled machines to bend metal and plastic tubes into exact shapes. Unlike hand bending, our machines follow digital blueprints to make the same perfect bend every time.

We can bend round, square, and rectangular tubes with amazing accuracy – down to ±0.005″ (that’s about as thin as a piece of paper)!

Materials We Can Bend

We can bend many different materials at Istar Machining:

Metals:

• Stainless steel (types 304 and 316)
• Aluminum (types 6061 and 6063)
• Copper
• Titanium
• Special metal mixes (called exotic alloys)

Plastics:

• PVC pipes
• Polyethylene
• Nylon

Each material has special features – some are strong, some won’t rust, and others can handle heat really well!

How Big (or Small) Can We Go?

Our machines can handle a wide range of tube sizes:

This means we can make tiny bends for medical devices or big bends for industrial pipes!

Industries We Help

Our CNC tube bending service helps many different industries:

1. Automotive: We make parts for car exhaust systems, structural tubing, and hydraulic lines that carry fluids in cars and trucks.
2. Aerospace: Our team creates perfect heat exchanger tubes and fuel lines that meet strict airplane safety rules (AS9100-compliant).
3. Medical: We make medical device tubing with super-smooth finishes for tools doctors use.
4. Industrial: Our tubes are used in fluid transfer systems, hydraulic equipment, and custom metal supports.
5. Energy: We make special pipes that won’t corrode when used with chemicals.

Our Special Equipment and Technology

At Istar Machining, we use the best machines and technology:

Machines

• Hines CNC-B 200 series benders that can handle tubes up to 2.50″ in diameter
• Special electric-powered benders that make super-precise bends for aerospace parts

Bending Processes

1. Mandrel bending – This gives wrinkle-free results by putting a metal rod inside the tube during bending
2. Induction bending – Great for making big, smooth curves
3. 3D computer programs to plan complex geometries (fancy shapes with multiple bends)

Extra Services

• Cutting tubes to exact lengths
• Making special end shapes (notching)
• Laser tube cutting for precise holes and shapes
• Welding pieces together
• Putting complete systems together (assembled components)

Quality You Can Trust

We take quality very seriously at Istar Machining:

• Certifications: We follow strict rules for quality (ISO 9001:2015), aerospace parts (AS9100), and international trade (ITAR).
• Inspection: We use special ways to check tubes without damaging them (Non-destructive testing (NDT)) and 3D measuring machines that are super accurate.
• Guarantee: We check every single part to make sure it’s the right size, and we can tell you exactly where all our materials come from.

Real Applications of Our Tube Bending Services

Here are some real ways people use our bent tubes:

1. Car exhaust systems that fit perfectly and last longer
2. Roll cages that keep race car drivers safe
3. Fuel lines for airplanes that never leak
4. Medical instruments that help save lives
5. Handrails and furniture that look beautiful
6. Bike frames that are strong but light
7. Industrial machines that need to move fluids

Technical Details that Matter

For engineers and designers, here are the technical details of our CNC tube bending service:

We can also do 3D bends with multiple angles and directions in a single setup. Our CNC pipe bending services offer similar capabilities for larger diameter applications.
