Extrusion Punch

The bullet punch is used to manufacture extruded edges from a pre-existing hole. These extruded holes are typically used to accept sheet metal screws, provide spacing in panels, strengthening holes in parts that are mounted with rods or bolts, or to allow tapping into a deeper distance past the material thickness. On what applications do you use extruded holes?

Urethane Strippers

Stripping material is a crucial part of the punching process. The video on the left shows the standard stripper assembly on the Piranha P-50 ironworker. The yellow base is the stripper foot and the black tubes on either side of the punch are the urethane strippers. When released the urethanes press down on the stripper foot. The stripper foot then strips the material off the punch.

The photos on the right show the different urethane strippers we stock. Unlike the black Piranha strippers, the red and blue strippers slide over the punch to strip the material. The colors signify different hardness/durometer of urethane. The harder urethane (red) is used for thicker material, while the softer urethane (blue) is used for thinner material. It’s important to use the correct urethane to ensure the material will not distort while stripping. When the urethane starts to crack, it is time to be replaced. This helps ensure quality holes and extended tool life.

Special Punch

The punch and die industry is in contact with all types of industries ranging from manufacturing to jewelry, but recently we received a request to manufacture this punch for creating animal tags.  These tags are used by scientist to track the movement and habits of different water animals ranging from fish, like bass or tarpon, to shellfish. The punch is used to punch out a plastic tag that’s identified with a specific number.  This number is specific to the animal and the region it originates from. Scientists use this tag to track an animal’s habits and migration patterns.  No matter what industry you’re in, contact us today for all of your punching needs!

Louver Assembly

Click to Enlarge
Louvers have been around for hundreds of years, in the beginning these were made from barrels to allow ventilation while cooking or for a fire place while keeping the rain and snow out. With the evolution of technology, louvers can now be manufactured in metal to act as an air vent. These can be used on a variety of products such as lockers or any type of equipment that would need ventilation and temperature control. We manufacture louvers in form up and form down positions from 2” to 6” long. The louvers are manufactured with a spring load system to help strip the material off the cutting blades. These cutting blades are replaceable components within the louver assembly. Check out the video below to watch a louver in action on our Piranha P-50. Give us a call to get a quote on your louver today!

The Hardcoating Difference

Do you have a punching application where galling or tooling life is an issue? Or, is your particular punching application preventing you from using a punching lubricant? By utilizing a variety of Cleveland Punch and Die coatings, a better tooling life can be achieved. With a delivery time of approximately one week, we are able to get these items out the door much faster than the competition! CPD offers three types of coatings depending on your requirements:

CPD MG1 Coating:
  • A general purpose, gold colored coating, allowing higher punching speeds and longer tooling life.
  • Especially effective when punching copper, bus bar and aluminum.
  • Standard coating on our FP1 style punch.
CPD MG2 Coating:
  • A harder, more lubricious coating offering better performance in steels and aluminum.
  • Minimizes galling due to rapid punching.
  • Commonly used in higher strength steels and when the punch size is smaller than material thickness.
  • This coating is useful on "Insert" and "Style 1" Whitney™ punches.
CPD MG3 Coating:
  • The most abrasion resistant and hardest coating for punching heat resistant alloys.

The punches and dies shown are for a custom die set but coated punches and dies can be manufactured for any set up. Call Cleveland Punch today to get more information on our coating options!
