Material Capabilities

Hundreds of materials.
One source.

We maintain extensive inventory across elastomers, plastics, foams, and specialty materials. If we don't stock it, we source it.

Rubber / Elastomers

EPDM, Neoprene, Silicone, Nitrile, Viton, Natural Rubber, SBR, and custom compounds.

Plastics / Films

PTFE, Nylon, UHMW, Acetal, Mylar, Kapton, and other engineering thermoplastics.

Foam / Sponge

EPDM sponge, Neoprene foam, Silicone foam, polyurethane, closed and open cell materials.

Specialty

Cork rubber, graphite, non-asbestos fiber, EMI/RFI shielding, PSA-backed composites.

Custom Manufacturing

Don't see what you need?
We make it custom.

Our product categories represent the most common components we manufacture, but they are far from the only ones. If you have a drawing, a CAD file, or even a physical sample, we can produce precision die-cut parts to your exact specifications in virtually any non-metallic material.

From single prototypes to high-volume production, our in-house tooling and broad material inventory allow us to respond to custom requirements with competitive pricing and realistic lead times.

Frequently Asked Questions

Questions about our custom gasket and washer programs.

Are you ISO 9001 certified?
Yes, ISO 9001:2015 certified. Documented quality management covers incoming material verification, in-process inspection, calibrated measurement, final inspection, non-conformance handling, corrective action, and full lot traceability. AS9100-ready for aerospace, with MIL-spec and FDA 21 CFR 177.2600 / USP Class VI grades available on request.
Can you handle FDA, medical, or aerospace applications?
Yes. ISO 7 clean room for medical / semiconductor / aerospace programs that need contamination control. FDA 21 CFR 177.2600 silicone, USP Class VI, platinum-cure silicone, and Kapton in stock. AS9100-ready quality documentation available.
What manufacturing processes do you run in-house?
Flatbed die cutting, rotary die cutting, lathe cutting, machining, slitting, sheeting, pad printing, and custom packaging. Tooling is built in-house at our Fontana plant so prototype-to-production lead times stay tight.
What materials do you stock?
Every major gasket elastomer (EPDM, Silicone, Viton, Buna-N/Nitrile, Neoprene, SBR, Polyurethane, Fluorosilicone), plastic washer compounds (PTFE, UHMW, Nylon, Delrin, Kapton, Mylar, Lexan, G-10, PVC), compressed fiber (Garlock, Klingersil, Interface, Non-Asbestos), graphite, cork, felt, and conductive EMI/RFI stock.
What thickness range can you cut?
From 0.001 inch thin films through half-inch foam and rubber on flatbed presses. Rotary die cutting handles 0.001 to 0.250 inch roll stock for high-volume PSA-backed parts. Compressed fiber and composite gasketing usually ships 0.015 to 0.250 inch.
How fast do you return a quote?
Most RFQs come back within one business day. Simple profile updates to an existing tool quote same-day. Send a drawing, DXF, or competing part number and our engineering team reviews material, tolerance, and volume before pricing.
What is the minimum order quantity?
Minimums depend on the part and material. We cut prototype and first-article quantities for engineering evaluation, then scale up to production volumes from the same tooling. For high-volume programs we run JIT, VMI, and Kanban replenishment out of Fontana, California.
What should I send with an RFQ?
Ideal: a drawing or DXF, material spec (or compound family), estimated annual volume, and any regulatory callouts (FDA, USP Class VI, AS9100, MIL-spec). If you only have a sample or a part number from a competing supplier, send that and we will reverse-engineer the spec before quoting.
What are typical lead times?
Prototype and first-article parts usually ship in 5-10 business days. Production runs from existing tooling are 2-3 weeks depending on volume and material lead time. Rush and expedite options available on a case-by-case basis.
