Our capabilities include:

• Die Cutting • Water Jet Cutting • Laser Cutting
• Compression Molding • Transfer Molding • Extruding
• Slitting • High Precision Cutting • Bonding/Vulcanizing

We can also produce or acquire nearly all rubbers and most plastic and paper goods and convert them into your finished application, whether it be a complete part, one of our specialty EMI/RFI Shielding Materials, an inclusion of a special adhesive, liner or combination there of, a smaller roll width, or simply your desired roll/sheet stock at our discounted prices. Our unique capabilities enable us to cut just about anything from the softest of rubbers and papers to the thickest metals up to 8" thick titanium! Our large machinery and specialized cutting surfaces allow us to do this as seemless applications up to 6 feet x 12 feet rectangular footprints while still holding to the strictest of tolerances commonly required by the aerospace/defense fields that we service along the various other industries we service. We can of course do bonding as well to create even bigger parts and have full in house molding capabilities as well. Let us be your single source for all of your needs. We hope the following information can assist you in selecting the proper material for your product and of course we carry many materials not listed below and can cut from any material you request.

Large / Oversized Gaskets
Top Of Gasket Page
Frequently, your applications may require a need for an above average sized gasket that you may be having a hard time finding someone to manufacture. We pride ourselves on our ability to manufacture to any size using our knowledge and experience. Our customers, frequently, come to us for oversized gaskets in any shapes and sizes, most typically in the oversized area, large "washer style" gaskets or ID/OD Rectangles typically referred to as "window frame" gaskets. Whether you deem your design large, very large, or even "too large" we will gladly manufacture it for you.
High Precision Gaskets
Top Of Gasket Page
When necessary we have the unique capabilities of holding to even the tightest of tolerances, within a micrometer. When your gasket designs must be perfect please contact us and we will manufacture with that in mind. These special gaskets are typically used by aerospace manufacturers where the gaskets must be true to design and there is no room for error. Keep in mind when requesting this option tooling will be substantially more expensive.
Water Jet Cut Gaskets
Top Of Gasket Page

WaterjetGaskets1WaterjetGaskets2

Our Water Jet Machines can cut everything from common rubbers and plastics to the hardest of steels including 4" titanium. The advantages of Water Jet cut parts are that they involve no tooling which allows for quick deliveries and no tooling charges. They also enable extremely precise parts to your specifications. Our water jet machines (one such is pictured above) hold industry leading tolerances of +/- .003" with repeatability to +/- .002". The particular machine pictured above also represents one of the largest cutting surfaces available (6 ft x 12 ft). This enables us to provide seemless parts with no bonded joints in any size that fits within that rectangle area.

Other benefits to Water Jet Cut Gaskets are with thick rubbers in both solid and sponges where the typical method of manufacture, die cutting, would cause for severe concavities, die cutting provides a seemless wall similar to if the part had been molded, though not quite as smooth. If you are having a hard time with any of your designs or ideas and are not sure if it is best to Die Cut, Mold, or Water Jet cut the part call us and we will decide for you and provide you with exactly what you desire.
