First Class Custom Metal Die Cutting

Premier Customer Service, Larger Capacity, and Timeliness Since the 1940s

Metal is notoriously one of the most difficult materials to die cut, but with over 75 years of die-cutting experience, our team at Colvin Friedman has the expertise to adjust and accommodate your specific needs. Whether you are manufacturing a specialty product component or require tight tolerances for a large production order our custom metal die-cutting process is designed to assist our customers, no matter their industry.


Custom Metal Die Cutting Process

Die Cutting Process

Step 1: Die Cut Product Design (1-3 Days)

  • Ensure Quality of design via prototype
  • Select material and match it to the appropriate cutting method
  • Ensure material will not be warped and machinery will not be damaged

At the beginning of every custom metal project, we consult with the client on their component. If the client does not have an existing prototype, we will create one to guarantee the design’s quality and make adjustments as necessary. For metal projects, we go to especially great lengths to select the proper material and match it to an appropriate cutting method. We consider details such as the size of the component, the force of the die on impact, and the potential need for die maintenance to avoid issues such as cracking or dulled machinery down the line.

Step 2: Die Creation (2-7 Days)

  • Dies are tooled by world-class die toolers
  • Utilize specialized materials for die creation to avoid wear when cutting metal
  • Coat or surface treat dies as necessary

Once the design is set, die creation is carried out by some of the top die toolers in the world. Depending on the metal being cut, materials like D2 tool steel, A2 tool steel, or carbide are used when molding dies to allow for the cleanest possible cut. Additionally, dies may be outfitted with specialized coatings to reduce friction or increase hardness. Dies may also undergo surface treatments like carburizing or nitriding for similar purposes as necessary.

Step 3: QMS Customer Approvals (Customer Dependent)

  • Initial sample product run
  • The sample product is extensively tested and awaits approval

Once dies are created, we generate small, initial production to guarantee the quality of the product, avoid burring, and optimize the settings and alignment of the dies. We perform tolerance level tests, fit and function tests, and overall dimensions tests. All final production approvals are customer-dependent and we encourage clients to perform their own independent tests.

Step 4: Production (Order Size Dependent)

  • Continual QMS throughout the whole production
  • Allow for Lubrication and cooling so as to not damage product or machines
  • CNC to precisely calibrate machines and maintain tight tolerances

Following customer approval, we begin the full production. Our QMS procedures continue running throughout the production to protect against material buildup, die wear, or cracking in the metal. We continually lubricate the system to avoid unnecessary friction, while using cooling sprays to maintain optimal operating temperatures. Our computer numerical control (CNC) technology helps keep our machines calibrated to exact standards, ensuring each product is smoothly cut and of the highest quality.

Method Selection: Rotary vs. Flatbed

As metal is a more difficult material to cut, varying in hardness, thickness, and flexibility, proper die-cutting method selection is crucial to ensure quality products. While most metals may require flatbed die cutting for their ability to handle denser materials, some metals or metal foils, if flexible enough, may benefit from rotary die cutting to achieve an expedient production run.

Rotary Die Cutting Flatbed Die Cutting
Pros Cons Pros Cons
Suitable for high-volume orders, providing economies of scale Higher setup costs, making it less economical for small batches More adaptable for low to medium volume without high setup costs Slower production rates can lead to longer turnaround times
Consistently high precision, ideal for complex and detailed designs Limited to metals in roll form, reducing material options Capable of handling a wider variety of metals and thicknesses Higher material waste due to spacing between cuts, affecting cost
Efficient material utilization, reducing waste and costs Changes in project scope or design can be costly and complex to implement Flexibility in setup allows for customization and changes in design Operation can increase labor costs due to material handling
Faster turnaround times for large orders Typically requires a long-term commitment due to setup investment Often more cost-effective for short runs and prototypes Less suitable for very high-volume jobs due to slower speeds

Custom Metal Cutting: Materials

Our team at Colvin Friedman most commonly cuts thinner metal or metal foils for custom projects. These foils come in several different varieties, have different strengths, and are each used for a multitude of purposes.

Below we’ve outlined a description of each, including some common uses and the preferred die-cutting method.

Most Commonly Cut Metal Foils

Foil Description Often Used For Thickness Best Cut With
Aluminum Foil Aluminum Foil is valuable for its lightweight and corrosion-resistant qualities. It is soft, malleable, and incredibly flexible, making it ideal for die-cutting.
  • Heat Shields
  • EMI/RFI Shielding Gaskets
  • Labels/Tags
  • Capacitor Foils
~0.006 mm - ~0.2 mm Rotary or Flatbed Die Cutting
Copper Foil Copper Foil has a red-brown color and is more rigid than aluminum foil. It is a great thermal and electrical conductor and is corrosion-resistant.
  • EMI/RFI Shielding
  • PCB Traces
  • Electrical Applications
~0.018 mm - ~0.127 mm Rotary or Flatbed Die Cutting
Brass Foil Brass Foil is an alloy of copper and zinc and has a gold-yellow color. It is stronger than copper, but is more difficult to cut. The hardness may vary based on the ratio of copper to zinc.
  • Decorative Components
  • Electrical Connectors
  • Shims and Spacers
  • Battery Components

Specialized Metallic Foils

The metallic foils below are less commonly used in die cutting, but can be cut in special applications. They are generally much stronger and optimal for heavy-duty usage, but far harder to handle.

Foil Description Often Used For Thickness Best Cut With
Stainless Steel Foil Stainless Steel Foil is an alloy foil made up of 10.5% or less of chromium. It is corrosion-resistant and very hard, making it challenging to handle.
