Proven Reliability, Faster Turnaround

Our Quality Management System is certified to ISO 9001:2015 ensuring a consistently precise standard of work, which translates to greater engine reliability, longer service intervals, lower through-life operating costs and better value for money.

Recent significant investment in programmable CNC crankshaft grinding and valve seat machining centres has also enhanced our ability to deliver repeatable precision and faster turnaround time. For instance, our CNC crankshaft grinder – the only one of its kind in Australia – allows us to quickly grind every journal to very high levels of repeatable accuracy. This investment in our machining capability, together with our industry-leading ERP System and integrated Quality Management System, enables us to perform at world-class standards, to minimise your downtime and maximise your profitability.
