Company profile
Agate Products
Chessington precision-machining company making semiconductor-equipment components in silicon, quartz, sapphire and other hard materials.
Company overview
Agate Products manufactures precision-machined components in hard and ultra-hard materials from Chessington. Founded in 1946, it supplies prototype and production quantities to a diversified international customer base. Its machining processes include cylindrical, surface and CNC grinding, drilling, honing, lapping and optical polishing, using diamond-based material removal. The company processes alumina, sapphire, silicon carbide and quartz, alongside other specialist materials. Its semiconductor relevance is explicit in its silicon and quartz offerings: it manufactures complex silicon components to customer drawings and supplies semiconductor-grade fused quartz in machined forms. Silicon can be sourced by the company or supplied by customers, including wafer material and larger ingot sections. This is a precision materials and components business, not an evidenced semiconductor-device manufacturer.
