When precision matters, off-the-shelf parts may not be the right fit. That’s where custom die-cut components come in—designed to your exact specifications and made from materials that match your application needs. But what goes into making a custom die-cut part? The process blends engineering, material science, and precision manufacturing—starting with your concept and ending with a part ready to go to work.
Here’s a look behind the scenes.
1. Dimensional Drawing
The process begins with a CAD file, or even a physical sample. Whichever format your design is in, experienced application engineers can help translate your needs into a workable design.
At this stage, we’ll review:
Dimensions and tolerances
Functional requirements (e.g., sealing, insulating, masking)
Environmental conditions (temperature, pressure, exposure)
Preferred or required materials
If you're unsure what material is best, many converters can help guide the selection based on your product application. As a 3M Preferred Converter, we have access to their full line of material experts when questions arise.
2. Material Selection
Material choice is one of the most critical decisions in the die-cutting process. Options vary widely—from foams and films to rubber, tapes, and high-temperature silicones.
Things to consider:
Does the part need to resist extreme heat or chemicals?
Should it be flexible or must it be more stable or rigid?
Does it require an adhesive backing or other treatment such as a pull tab for removal?
Custom die cutting often includes laminating adhesives, multi-layer forms, or split liners for easier handling during assembly.
3. Prototyping and Sampling
Before committing to production (as well as tooling), most projects go through a prototyping phase. This allows you to:
Confirm fit and function, making sure it is aligned with part dimensions
Test the performance of the part in real conditions
Make design adjustments before tooling is cut for production
Samples can be produced using our digital plotters, lasers, 3D printers, or flatbed die cutting machines—quick and cost-effective for short runs or concept validation.
4. Tooling and Production Setup
Once the design is finalized, it’s time to acquire the tooling. The choice of tooling depends on the manufacturing process, part geometry, material type, and production volume.
Based on this, one of the following could be chosen:
Flatbed dies for low-to-medium volume, large parts, or thicker materials
Rotary dies for high-speed, high-volume precision cuts
Laser cutting for tight tolerances, small features, or flexible production without tooling
Some applications may also include kiss cutting, slitting, or pull-tab designs to improve ease of use during assembly.

5. Converting and Quality Control
During the converting process, quality control measures are in place to ensure consistency and accuracy.
Visual inspections and automated vision systems
Dimensional verification against CAD files
Clarity of barcodes or lot numbers printed
Adhesive performance checks
Quantity verification
The result: finished parts that are ready to be added to your production process.
6. Packaging & Delivery
Custom die-cut parts can be packaged in whatever format fits your workflow. Whether individually bagged, supplied as separate sheets or rolls, or kitted with other parts and labeled, our goal is to help get the parts to you in the way that will best suit your operations.
More Than Just a Cut
From CAD to cut, the custom die-cutting process is built around your needs—from design to delivery. This process, and the teams involved, focuses on delivering performance, efficiency, and value.
