Flexible gaskets, engineered for success
Custom Fabricating & Supplies manufactures custom gaskets from materials such as silicone rubber, Neoprene, Nitrile, EPDM, Poron®, Santoprene®, RN-8011, Viton® ,Teflon / PTFE, cork, fishpaper and much more. We can source the gasket material or use your customer-supplied materials. Our in-house engineering team will work with you to ensure the perfect fit for your custom gasket needs.
In addition to custom gasket making capabilities, CFS offers large format cutting and adhesive laminating services. We can easily provide kiss-cutting or split liners for your gaskets requiring an adhesive backing.
CFS utilizes high-speed rotary die cutting equipment to efficiently produce custom gaskets, making it an excellent choice for high-volume or repeat production. Although the initial investment in tooling is higher, the efficiency and speed of this method make it highly economical for large runs and consistent part output.
Our Atom Flash dieless knife cutting machines use standard .dxf CAD files to produce precision parts—no tooling required. You can supply your own file, or we can create one for you. Design revisions are simple: just update the file and production can resume immediately.
Unlike traditional die-cutting, this method eliminates the “hourglass” edge distortion often seen in thicker or softer materials. It also enables tighter tolerances, including RMA Class 1 or better on sponge and soft substrates where precision is critical. Ideal for silicone, neoprene, EPDM, and other flexible gasket materials.
Flatbed die cutting is an efficient and cost-effective method for producing gaskets, especially for short runs or complex designs. Using steel rule dies—significantly more affordable than rotary tooling—our Preco automatic hydraulic press delivers exceptionally precise cuts, even on thick or dense materials. This makes it ideal for applications requiring larger-format gaskets or intricate shapes, without the high tooling costs of other processes.
Injection Molded Gaskets and Seals
Injection molding is the best choice for intricate, high-volume production runs of rubber seals and gaskets which require tight tolerances. Rubber injection molding involves feeding material into a press, which is then warmed and injected into a mold. This molding process is the most precise because the injection process controls the pressure, temperature and speed at which the material enters the mold.
Compression Molded Gaskets
Compression molding is a tried-and-true method of manufacturing simple rubber parts. The process is akin to waffle- making — a given amount of uncured rubber is placed into a mold cavity, which is then closed and heated. When the parts have cured, they are removed from the mold. Compression molding produces parts with a low tooling cost and lead time. Tight tolerances are difficult to achieve with compression molding and may not be the best choice for intricate geometries.
