Cut Gaskets
Environmental Gasket Company, utilizing state of the art numerically controlled gasket cutting equipment, cut gaskets to all Chinese and international flange standards as well as non standard gaskets. Gaskets can be cut from a large variety of gasket sheet and non metal materials.
This gasket cutting technology allows us to cut standard flange gaskets and non standard gaskets to any shape, size or quantity to the highest precision. Working with our customers’ CAD drawings sent to us on disk, C.D. or e-mail, gaskets are produced to the exact size requirements for the application. Additionally, gasket cutting can be programmed from drawings, samples or templates, with no need for special tooling.
Our gasket cutters operate with all major CAD programs, the latest nesting software, combined with image projection equipment to project the shape of the object onto the sheet, enabling the maximum number of gaskets to be produced with minimal material wastage.
