At Cyco, our KEYENCE IM-X1000 Optical Measurement System allows us to inspect every production batch for dimensional compliance.

As you can see here, we can measure 10–15 valves at once, verifying critical dimensions and confirming each part is within tolerance before it leaves our facility.

Consistent parts. Consistent quality. Built to perform.

At Cyco & U.S. Seal, all our rubbers are premixed in-house at the manufacturing plant. The quality standard of the rubber material is not in the hands of a third party material supplier. This lets us control all the qualities of the rubber.

Every great gasket starts long before it reaches your engine.

Here’s a behind-the-scenes look at the development process of the gasket mold

🔹 Projection – The gasket profile is projected and enlarged for maximum accuracy.
🔹 Grasp Size Points – Critical dimensions are captured to ensure a perfect fit.
🔹 CAD Design – Those measurements are imported into the computer to create the final digital model.
🔹 Wire EDM – The mold components are precision cut using Wire EDM technology.
🔹 Mold Assembly – The finished mold is assembled and ready to begin producing production-quality gaskets.

It’s a process built on precision, the smallest details matter.
