Die Cutting Services
Medical products can have complex shapes and stringent requirements. At Colvin-Friedman, we not only provide die-cutting services for designs and materials that other companies cannot, but we have been doing so for 75 years. With the capability to ramp up to 2,000 to 4,000 parts per hour, Colvin Friedman is your partner for the most delicate and/or the most high-throughput projects in the medical industry.
Examples of Medical Products We Can Die Cut, By Material
Below we’ve listed categories of material that we can die cut, with an emphasis on explaining the differences in methods: rotary die cutting can be used for very high-speed production, but the level of detail and thicknesses of material that can be processed is different than that of flatbed steel-rule die cutting.
Material Type
Adhesive Materials
Fabric and Non-woven Materials
Plastic and Polymer Films
Foam Materials
Rubber and Silicone
Products
-Adhesive bandages – Medical tapes – Transdermal patches – Electrode pads for ECG/EKG and TENS units
– Surgical drapes – Disposable gowns – Non-adhesive gauze pads – Compression bandages – Filter media for face masks and respirators
– Diagnostic test strips – Packaging materials for sterile medical supplies – Protective covers for medical equipment – Simple components for wearable medical devices
– Padding for prosthetics and orthotics – Cushioning for medical equipment packaging – Absorbent materials for wound care products
– Gaskets and seals for medical equipment – Tubing connectors – Simple valves for medical devices
We are also capable of working with far more material thicknesses with our flatbed die-cutting processes. Below are some of the expanded capabilities you might find with these production systems in use at Colvin-Friedman.
As noted above, die cutting for the medical industry can include several different materials, each with its particular strengths and weaknesses. We put together a table of best practices for each material type. If a die-cutting vendor mentions these issues and how to handle them, they may not be properly equipped to work with you on high-stakes projects with stringent requirements.
Issues and Best Practices for Medical Die-Cutting of Adhesives
Issue
Adhesive buildup on cutting dies
Sterility concerns with adhesives
Maintaining adhesive qualities during run
Best Practice
Clean dies with solvents and use non-stick coatings; implement a rotation system for large production runs.
Use clean rooms for sterility, or implement proper handling procedures and UV sterilization for specific applications.
Ensure constant temperature and relative humidity during production and storage.
Issues and Best Practices for Die Cutting Fabric and Fibers
Issue
Adhesive buildup on cutting dies
Sterility concerns with adhesives
Static Electricity Buildup
Best Practice
Keep dies sharp; ultrasonic cutting may help for certain products.
Monitor pressure and speed; use minimum force and frequently test samples.
Use anti-static bars or ionizers to reduce clumping; anti-static sprays are also effective in some cases.
Issues and Best Practices for Die Cutting Plastics and Films for Medical Products
Issue
Achieving Clean Cuts on Thin Films
Preventing Warping/Distortion
Maintaining Dimensional Stability
Best Practice
Use vacuum systems to keep films flat during cutting.
Implement backing systems to support the film throughout the process.
Acclimate materials to production conditions; maintain consistent temperature and humidity in storage.
Issues and Best Practices for Die Cutting Foams
Issue
Consistent Density Across Cuts
Variations in Foam Thickness
Limiting Tearing and Pulling
Best Practice
Use dies with varied blade angles and match cutting speed to pressure requirements.
Utilize adjustable cutting depths and floating cutting heads to account for thickness variability.
Implement an initial score cut followed by a through cut for thicker foams.
Issues and Best Practices for Die Cutting Rubber and Silicone
Issue
Dealing with Material Stretching
Clean Cuts on Soft Materials
Preventing Flash and Burrs
Best Practice
Use stabilizing backing materials and optimize cutting speed and pressure to reduce deformation.
Keep dies sharp, consider non-stick coatings, or chill dies before use.
Cryogenic deflashing is effective, but proper die design and controlled pressure are critical.
Of course, these are not the only concerns that any company has when choosing the right die-cutting company to help prepare their medical products. Other concerns are important to address before deciding on a vendor.
