KEW Foundries specialises in all grades of Grey and SG Irons and is closely affiliated with its clients to develop appropriate patterns and improve on existing products. Although KEW Foundries is an accredited supplier to the major mining houses in South Africa, it is also in the process of obtaining an ISO 9001:2000 listing. The company operates its own fleet of trucks, which ensures timeous delivery throughout South Africa.
The foundry has a modern laboratory equipped with an ARL 3460 Ret B optical emission spectrometer, metallographic section and a sand testing section.
There are two furan sand foundries on-site that are capable of producing castings from 1 kg to 12 500 kg, from single to complex shapes. The two foundries are supplied with metal from one 6000 kg furnace and two 3000 kg induction furnaces feeding off a common power pack.
As well as storing and maintaining customer patterns, KEW Foundries has its own extensive pattern library. In addition, KEW Foundries works closely with each client to design and modify castings and or pattern equipment to improve quality and reduce costs.
A full range of non-destructive testing can be performed on-site inclusive of magnetic particle, die-penetrant and ultrasonic testing. Physical testing is, at present, performed by an independent laboratory.
Each section of the engineering division including the design, material controls and production, is actively supported by the Quality Assurance Department.
