Custom Cut Gaskets to Your Specifications
Our industry-leading facilities and equipment allow us to complete any custom-request gasket project. We are ISO 9001:2015-certified, which shows our dedication to quality and ability to meet all industry standards. A number of methods can be used to cut a gasket to a client’s specifications, including:
- CNC Waterjet Cutting: A computer-assisted method of cutting that provides accurate and safe operation. The advantages of waterjet cutting include flexibility, cost-effectiveness, and minimal waste with maximum yield. This method of cutting is commonly used on soft materials, such as rubber and foam, as well as metal alloys.
- Die Cutting: Largely used for uncommonly shaped or sized pieces, die cutting is a cost-effective and reliable process. Materials cut with a die machine include plastic, silicone, and cork.
- CNC Laser Cutting: Utilizing a high-powered laser, precise cuts are made with the assistance of computer programming. This extremely accurate cutting method can be used on almost any material.
- Knife Cutting: A reliable method that allows for the cutting of large products. The knife cutting method is normally used for elastomer, foam, composite, and polymer materials.
