Precision Engineering & Advanced Manufacturing
Leading heat treatment & metal finishing companies in Singapore
Heat treatment and metal finishing are the special processes: they change what a part is made of rather than what shape it is, and they are usually the last thing done to it before it ships. They are also where qualification concentrates — an aerospace customer audits the plating line and the furnace, not just the machine shop — and where a failure is invisible until the part is in service. The companies below cover hardening, tempering, nitriding, vacuum and plasma processes, anodising, electroless nickel and precious-metal plating, hard chrome for large components, PVD and thermal-spray coatings, and post-weld heat treatment on site. An unranked set from the Singapore Industry Index's record.
