A wrong material choice can add weeks to a launch or cut part life in half; the right one keeps tolerances tight and costs in check. Colvin-Friedman converts eight broad substrate families on rotary lines that can hold ±0.005″ or flat-beds that handle thicker composites without creep.
Below you’ll find the pros, cons, and go-to use cases for every substrate we convert, from PSA-laminated papers to high-temperature silicones, plus quick links to deeper dives on each material family.
Your print or sketch is reviewed with a process engineer who locks in substrate choice, PSA lamination needs, and press type inside an in-house CAD system.
2. Die Fabrication (2-7 days)
High-grade steel tooling is milled, heat-treated, and sample-tested so that every edge stays sharp, whether the run goes on a 16-inch rotary line or a 40-inch flat-bed.
3. Prototype & Approval
Fit-and-function parts ship out for customer validation; tweaks happen now, not during production, keeping timelines tight.
4. Full Production
CAM-driven presses ramp to 40,000 units/hour (rotary) while the QMS and scrap-reclamation systems guard the ±0.005″ / ±0.010″ tolerance bands.
5. Stocking & Pack-Out
Finished rolls or kits flow straight into your Kanban or JIT pipeline; Colvin-Friedman’s automated stocking program delivers 99.99 % stock-out avoidance.
Industries We Serve
Electronics & e-Mobility
From EMI/RFI shields, thermal-transfer pads, insulating transformer sleeves, and battery-cell spacers, Colvin-Friedman supplies the sub-assemblies that keep power-electronics cool and quiet. Polyimide films such as Kapton® pair with PET when heat or dielectric strength matters, while rotary lines hold ±0.005″ even on six-cavity tools. A flat-bed option prevents creep on delicate form factors, so every part hits your SMT line burr-free and ready for reflow.
Renewable Energy & Storage
Whether you need electrode masks, manifold covers, composite back-sheets, or vibration-dampening cushions, our shop can switch from rotary to flat-bed mid-campaign to match material stack-ups. High-performance plastics like PEEK handle electrolyte splash, and carbon-fiber laminates ride out temperature swings in wind-turbine nacelles. The same tooling crew that cut the first gigafactory prototypes still signs off on mass-production QC today, shortening your climb from pilot to multi-megawatt scale.
Defense & Military
Mission-critical builds—EMI gaskets, high-temp silicone seals, ballistic impact pads, and scratch-free optical windows—leave Colvin-Friedman with full-lot traceability. Conductive elastomers and optical films are handled in controlled areas to block FOD or particulate contamination. Every unit ships with edges deburred and conductivity verified, ensuring reliability from desert flight lines to ship-borne comms bays.
Material Family Spotlights
Plastics & Films
PETG and opaque PVC handle everything from battery shields to retail clamshells while still meeting the shop’s tight ±0.005″ rotary tolerance. Add inline lamination and you can bond or insulate in one pass. Ready to compare grades and cut methods?
Open-cell PE cushions; cross-linked EVA seals under light compression; higher-density neoprene keeps vibration out of electronics enclosures. Decades of foam-specific blade profiles mean clean edges without melt or pull-out even on half-inch stock.
Silicone survives 200 °C plus ozone; EPDM shrugs off brake fluid; natural rubber absorbs shock on tooling fixtures. Engineers dial in durometer first, then match rotary or flat-bed force for a flash-free edge.
Kapton® polyimide tape insulates at 260 °C; double-coated acrylic bonds dissimilar plastics without rivets; VHB foamed acrylic stands in for spot-welds on EV skins. Kiss-cutting keeps liners intact for peel-and-stick kitting.
Ballistic nylon, automotive upholstery cloth, even silk overlays—each sees a tailored die and tension plan to block fray and stretch. Sample cuts arrive fast so pattern tweaks never stall launch.
Fish-paper insulates motors; SBS folds into sterile device trays; cellulose gasket board stands up to light oil. Steel-rule tooling delivers burr-free blanks at a price that keeps prototypes lean.
Acrylic holds trim panels, silicone seals to 230 °C, conductive PSAs ground EMI shields—each slit, kiss-cut, and tab-backed for drop-in assembly. Material labs vet bond strength before rolls hit the press.
Unfortunately, even small selection errors can stack up as quickly as a perfect rotary press run. Over the years, we’ve developed strategies to cut errors and maintain the tight tolerances our customers require:
Issue
Solution
Thin PET warps during kiss-cutting
Switch to a co-extruded PET-G or add a sacrificial carrier; tension stays even without upping clamp force.
Issue
Solution
Foam gaskets shear after thermal cycling
Specify a silicone-based PSA that retains tack at 150 °C rather than an acrylic that glass-transitions at 90 °C.
Issue
Solution
Fiber dust could contaminate optical assemblies
Move to kiss-cut with matrix removal, bag parts in-line, and add an anti-static wipe before pack-out.
Issue
Solution
Rubber seals blister in fuel exposure
Upgrade from EPDM to FKM; the fluorocarbon backbone resists aromatics without swelling, preserving seal compression.
Each fix costs less during design than after tooling, so flag concerns early; our process engineer will validate material and press combo during the CAD review step.
Quick FAQs about Colvin-Friedman’s Die Cutting
How fast can you ship a production run?
Typical lead time is ≈ 3 weeks after die approval; expedited slots may be available.
What materials do you cut most often?
PETG and polyethylene top the list, but the shop also converts paper, foams, rubber, tapes, and laminate stacks.
Can you talk to our ERP or Kanban board?
Yes. Colvin-Friedman integrates with most inventory systems and can auto-replenish to keep your line running.
What volumes make sense?
From prototypes to million-unit campaigns; during COVID-19 they produced 1M face shields in three months, proving high-volume scalability.
Do I need finished CAD files?
Not necessarily. Engineers can start from a sketch, refine tolerances, and prototype before tooling is cut.
