RECEIVING MATERIALS
Receiving materials from customer and segregating it for production
SHOT BLASTING
Segregated materials are inspected and the surface cleaned if required by steel shots as abrasive
JIGGING
Cleaned materials are loaded to the jigs
PRETREATMENT

QUENCHING
Galvanised materials are immearsed in cold water for quick removal of heat.
PASSIVATION
Materials are immearsed in passivation solution for preventing the formation of white rust.
MATERIAL OFFLOADING
