Custom Gasket Fabrication
Custom Fabricating & Supplies manufactures custom gaskets from materials such as silicone rubber, EPDM, Poron®, Santoprene ®, RN-8011, Viton ® and Teflon / PTFE. 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.
Rotary Die Cut Gaskets
CFS has many high-speed, rotary die cutting machines that are available for producing custom gaskets. This method is ideal for high-volume jobs or repeat orders. Initial set-up costs are usually higher due to the necessity of purchasing the rotary die, but the cost is quickly recouped when large quantities are needed.
Dieless/Digital Knife Cut Gaskets
Our Atom Flash machines produce parts from a common .dxf CAD file. You may supply your .dxf file, or we can create one for you. Dimensional changes to a part can simply be made by revising the file or creating a new one. No tooling is required.
The dieless knife system will fabricate parts without the “hourglass” distortion to the sides that may be found in some die-cut parts. This benefit is most visible on thicker and very soft materials. It can also produce parts to tighter tolerances than can be achieved with standard die-cutting methods. RMA class 1 or tighter tolerances are a possibility on sponge and other soft materials where such precision is required.
Flatbed Steel Rule Die Cutting
Steel Rule dies are much less expensive than rotary die tools. This makes short production runs, especially with complex geometries, far less expensive with a steel rule die than other methods. It is also a very good option when gaskets with larger dimensions are required.
Injection Molded Gaskets and Seals
Injection molding is the best choice for intricate, high-volume production runs of 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.
