The Tie-Bars and Platen Parallelism Are the Whole Game
What makes an injection moulding machine accurate is the clamp unit: four hardened, ground and chromed tie-bars that carry the clamp force and keep the fixed and moving platens dead parallel, so the mould closes evenly and the parts come out without flash. Those tie-bars are bright, precision surfaces that corrode in marine humidity, and the platens, if the machine is lifted or jolted wrong, can shift on the tie-bars and lose the parallelism the works set. The injection unit adds its own exposures: a heated barrel and a hardened screw and non-return valve that rust internally, and an oil and hydraulic circuit that weeps if it is not drained or sealed.
BENZ protects the machine where it actually matters. The tie-bars are VCI-wrapped and shielded, the moving platen is locked against the fixed platen so it cannot travel and brinell or misalign on the tie-bars, the barrel and screw are preserved internally with VCI, and the hydraulic circuit is drained or sealed with ports capped. Controls travel barrier-wrapped with desiccant. The machine is then bolted to a heat-treated, ISPM-15 skid on its true load path, sealed under barrier film for sea transit, with a reassembly reference for a fast restart.
