Sheet Metal Punching

At TMT, our CNC punching services provide the exact shape that is needed from various different types of sheet metal. We operate with the TruPunch 2020 to produce precise, clean results. It’s a fundamental CNC machining option when you need individual parts or just one big part punched out. It also has capabilities to perform both tapping and bending to metal parts in production.

CNC punch presses are a great alternative to laser cutting because of their speed and accurate ability to punch a variety of different shapes; both geometric and custom. Not to mention their overhead price being less than double that of laser cutting. 

Typically used for short to medium runs, our punch presses produce rapid turnaround on generic shapes, with our new machines being 3-4 times faster than the old ones. 

CNC Punched Parts & Applications

Plasma cutting creates a cost-effective way to cut thicker metals, and develop them into final components for usable parts and structures.

The chassis we fabricate are typically used to house electromechanical controls, from small handheld devices to large industrial testing equipment. All chassis are built to critical dimensions to ensure hole pattern alignment between different parts.

TMT builds custom brackets and miscellaneous laser cutting components. Our capabilities allow for fasteners and additional conveniences to be built-in to almost any manufactured part. 

About Our Sheet Metal Punching Process

Controlled by a CNC punch-press machine, CNC punching creates holes or special indents on various types of sheet metal. CAD files feed the punching machine with exact details to make sure precise movements are met and the machine punches in the correct shape. Thus creating clean-edged shapes at low tolerances in a quick manner. CNC punch presses are able to function with various sheet metals up to 12 gauge thick.

Our CNC Punching Process:

1. The design is uploaded into our software as a CAD file and the program for the machine is created.

2. After that, the CAD file program is loaded into the machine and the correct punch tooling is placed in the punch press in order to create the desired part. The tool is able to punch the precise shape, dimple, or embossment into the metal.

3. Using the CAD file, the machine moves the sheet metal in an x and y direction, accurately placing it under the punch press for the exact placement of the punches.

Metal Finishes for Punched Parts

Also called “Bead Blasting,” this finish creates a smooth matte appearance on metals.

Parts and applications may have an anodized finish for a wide variety of custom colors, which may include clear, black, gold, or desired custom colors.

  • – Type II Anodized Finishing creates a finish that is resistant to corrosion.
  • – Type III Anodized Finishing creates a thicker finish that is more wear resistant than its lesser option.

Powder coating is a painting process where powdered paint is sprayed on a part or application prior to heating. The result is a strong layer that is more resistant to wear and corrosion.

This process also allows for a wide selection of colors for the further  customization of color.


This layer of zinc coating provides protection from corrosion. 


This three-step process coats fabricated metals in a bath of molten zinc, protecting it from corrosion.  

A process that alters the physical and chemical properties of a metal, by heating it or cooling it to extreme temperatures to make the material harder or softer. 

Using a pump, spray, or pressurized vessel, liquid paint is evenly applied to a part or application. 

This dipping (immersion) process uses organic paint particles, where the paint based finish is able to stick on a metal surface with the help of electrical currents. 

If a custom finish is required for an order, or the finish is not listed on our site, please include this information when requesting a quote. We can likely still complete the project.
