About SemiMat
SemiMat GmbH, based in Büdingen, specialises in quartz glass (silica, fused silica) and offers a complete service for quartz glass components: from material selection and procurement, through new production in single-piece and series manufacturing, to cleaning, repair and measurement of used parts. The company is part of the Schunk Group and can look back on 25 years of experience in the quartz glass field. For cleaning, a cleanroom of ISO class 5 is available, in which components are cleaned wet-chemically (with various acids), mechanically and thermally, and packaged. Repairs include fusing of cracks, reworking of chipped areas, replacement of attached parts such as ground joints and flanges, as well as flame polishing and mechanical machining. SemiMat also sells quartz glass raw materials (tubes, rods, plates, blocks, flanges, rings, discs), cut to size using its own cutting equipment, made from high-purity quartz materials from its partner Momentive. As the official and exclusive European representative of the Korean manufacturer Vision Tech Co., Ltd., the company primarily serves the semiconductor industry. A collection and delivery service with its own vehicles and transport boxes rounds off the range of services.
