Through research and development and testing of various metal materials, our metal team experts can provide a wide range of high-performance solutions for a precision fit to your application. Factors such as temperature, fatigue, wear and friction are considered.
While the inner design of a metal seal is key, the outside is just as important. Metal seal platings and coatings have exceptional features in sealing technology.
- The additional soft layer is instrumental in improving the leakage rate, used to fill the roughness of the counter flange and enhance the sealing performance.
- The softer the plating, the more it can improve and cover surface irregularities in the hardware. Generally, a metal seal lies side by side with the high demands placed on the surface quality of the customer’s hardware.
- Special patented coatings are used to improve the wear resistance. PTFE is typically applied, while plated seals use gold, silver, copper, tin, and nickel as a top layer. For jacketed seals, aluminum lining is used.
Since metal seals are engineered to address critical pressure, temperature and leak rate challenges, they have a greater design flexibility. As a result, our team has designed and manufactured special shapes to accommodate typical dimensional tolerances.
