Tube Punching

A tube punching machine is specialized equipment designed to create precise holes in cylindrical or tubular metal materials such as pipes, tubes, and hollow sections. This process involves using a die and punch system engineered to maintain the tube’s structural integrity while producing clean, accurate cutouts.

Purpose
The primary function of a tube punching machine is to punch holes into round or square tubes without deforming or damaging the tubular shape. This enables the addition of mounting points, fastener holes, or other custom cutouts necessary for assembly and fabrication.

Application:

Automotive exhaust and muffler systems
HVAC ductwork and components
Structural tubing in construction and industrial frames
Fencing and railing fabrication
Aluminum and steel tubing for manufacturing

Benefits

High precision hole placement with minimal distortion
Quick tooling changes for fast production runs
Adaptability to various tube diameters and wall thicknesses
Compatible with custom mandrel dies and slotting tools to meet specific design requirements

2 Types of Tube Punch

There are 2 principal methods of tube punching. Click on the following bullets to find out more!

Dimpling: Often used for cosmetic purposes or in applications where the hole does not need to be fully cut through or structurally critical.
Mandrel Style: Ideal for applications where a high-quality, precise hole is needed, such as in hydraulic lines, exhaust pipes, or any tubing that requires exact hole placement without compromising structural integrity.
