American Seal & Packing Cuts Gaskets Including Flexible Graphite, PTFE, Expanded PTFE, Non-Asbestos, Mica, and Rubber. Name brand materials include Durlon, Garlock, Thermoseal, Viton, Aflas, Grafoil, and Teadit.
American Seal & Packing Cuts Gaskets of all types, Including: PTFE, Expanded PTFE, non-asbestos brands like Garlock, Durlon, Thermoseal and Teadit. We also cut generic vegetable fiber, beater add, cork, and various rubbers – Nitrile, Buna-N, SBR, EPDM, Viton®, Hypalon®, Aflas®, natural rubber, and Graphites, GRAFOIL® Flexible Graphite (including with foil or tang) closed cell sponge, open cell sponge, Neoprene® and other “soft goods”.
Cutting Gaskets Use To Be A Hands-On Business. A Skilled Worker Would Carefully Produce A Die And Use It To Cut A Gasket Out Of The Gasket Material Of Choice. This Is Still Done, But To A Much Lesser Degree. The image to the left is a knife-edge CNC (click on it to see a video). The beauty of using what essentially is a router with a reciprocating blade is that no dies are required, which means no die charges. A drawing does need to be created in a vector-based software (Corel Draw, Adobe Illustrator, Auto-Cad, Solid Works, or alike). We have cut using customer drawings, or we can produce the drawings for a small fee.
Gaskets Made In High Volume Are Still Generally Cut Using A Steel Rule Die. A Clicker Press Can Cut Up To 45 Gaskets A Minute. No Computerized Process Has Yet Reached Those Speeds Of Cutting Gaskets, But They Do Keep Getting Faster.
It was not until after 2010 that knife edge CNC (Flash gasket cutters) were in use. The industry has used Clicker presses of multiple types for over 100 years. They still have their place, particularly in high-volume cutting. The most common type of clicker press is a swing arm press, but a Beam Press, Clamshell press and Traveling head press all effectively cut gaskets. The size, material, and required speed define which is the best tool for the gasket-cutting job.

Laser cutting is another solution to the cutting job. We like using the laser on PTFE and acrylics. It provides a smoother edge than gaskets cut with a clicker, which tends to pull the material as it cuts. On PTFE it is actually vaporizing the PTFE due to the high heat. That high heat generated on by the laser is the reason lasers do a poor job of cutting any rubber, or non-asbestos gasket. It will burn the edge. Lasers can be used on Flexible Graphite but it must be a specific type of laser. Lasers can even cut metal.
Water jet is the 4th type of gasket cutting we provide. Just like the Knife edge CNC, and Laser this is a computer-controlled method of cutting, however, water with an abrasive is pushed through a jet allowing it to make precise cuts in a wide range of materials including steel.

What Are the Cutting methods for making a gasket?
Gasket cutting ranges from simple cutting by hand, cutting with a tool, cutting with a die, or using one of the 3 common CNC methods to cut a gasket. The CNC methods include laser, knife-edge CNC (Flash cutting), or water jet cutting.
The CNC methods have become the most often used due to the elimination of the need for a steel rule die. Die-cutting is still the most cost-effective for high-volume production.
AS&P offers all of the above methods of gasket cutting. Our objective is to use the best method for our customers based on cost, speed, and quality.
