How Do You Make a Gasket? Inside the Derby Gaskets Factory

It is one of the most common questions we are asked: “How do you actually make a gasket?” The answer combines modern machinery, decades of experience, and a commitment to precision manufacturing right here in Derby, UK.

With a wide range of gasket materials in stock and a team that moves fast, we make sure you get the gaskets you need on time and to spec.

Choosing the Right Gasket Material

Every gasket starts with choosing the right material. This step is critical to performance. Some applications demand gaskets that can withstand high temperatures or high pressure, while others need to be oil free or food safe.

That is why Derby Gaskets works with a wide range of gasket materials, including:

• Natural Rubber – flexible and cost-effective for general sealing.
• Neoprene – resistant to weather, oils, and moderate chemicals.
• Nitrile (Buna-N) – ideal for oil and fuel applications.
• EPDM – excellent resistance to heat, steam, and water.
• Silicone – handles extreme temperatures and food-grade use.
• PTFE (Teflon) – chemically resistant and suitable for hygienic environments.

Each material offers different properties to meet the exact specification required by the customer.

Gasket Cutting Methods

Once the material is selected, we cut it to shape using one of several specialist machines:

• CNC Knife Cutting provides accuracy and speed on complex gasket shapes.
• Clicker Presses are ideal for repeat, high-volume gasket production.
• Waterjet Cutting delivers intricate patterns and a clean, precise edge without heat distortion.
• Die Cutting uses custom-made tooling for perfect consistency across thousands of identical gaskets.

Built to Last

At every stage, Derby Gaskets carries out rigorous quality checks to ensure each gasket is fit for purpose and built to last. The machines provide precision, but it is the knowledge of our team that ensures every gasket is the right fit for temperature, pressure, or oil free use.
