Quality

Precision Process

Producing products that meet the strictest tolerance requires attention to detail and experience. This process begins at the design stage and follows through to every step of the production cycle.
Quality control systems are built into every aspect of the production process and include the use of equipment that includes, composition spectrometer, tensile strength testing equipment, impact / drop testing equipment, microstructure analysing equipment and CMM coordinate measuring equipment.
