Cast Products is one of the oldest and most important manufacturing operations in the Scaw Group. The Scaw foundries employ approximately 2,500 people across its six foundry plants. Each plant specializes in specific products in terms of process control and plant optimization, resulting in the best quality at the lowest cost of manufacture. Three large on-site machine shops, with extensive machining capabilities, allow Scaw to supply finished products which are ready to install.
Scaw's Germiston Foundry in South Africa is one of the largest foundries in the southern hemisphere and produces castings in finished weights up to 30t. It is a leading supplier of single-piece, thin-walled locomotive and passenger frames, freight car components and high integrity cast steel railway wheels. The foundry holds the American Association of Railroads' approval for the manufacture of freight-car side frames, bolsters and cast-steel wheels.
Other products include large gear segments, high-carbon, high-chromium, abrasion resisting coal grinding elements for coal-fired power stations, high-chromium iron mill liners and impact crushing parts, stainless-steel coiler drums, and a range of slag ladles for the metal processing industry. Arc furnace melting units and a 25t capacity ladle vacuum degassing unit serve the foundry where steels can be produced with lower sulphur, nitrogen, oxygen and hydrogen contents, particularly necessary for the manufacture of high strength, low-alloy steels.
Scaw's other foundry operations (Standard Foundry, Boksburg Foundry, Dimbaza Foundry, Eclipse East Foundry and Eclipse West Foundry) produce a vast range of cast wear parts from a variety of materials that can be custom designed according to individual customer specifications. The product range includes mill liners, cone and gyratory crusher wear parts, jaw crusher wear parts, impact crusher wear parts, dragline and shovel parts, shredder wear parts, railway parts and mining spares.
Scaw is an ISO 9000-series accredited organization manufacturing products to meet the requirements of the appropriate international certification authorities. Scaw's safety, health and environmental management systems are aligned with the international ISO 14001 and OSHAS 18001 standards.
