Jun Lee on 02 Nov 12choose the correct steel for mould base and mould main steel. For example, if you need to make a 4 cavities crate mould, then you need to make to use a pre-hardened steel with HRC bigger then 33 for mould base. You have to choose the correct steel or material for the durable mould components. make the correct harden treatment to each steel piece and make the steel hardness controlled, you can not make it too hard. the moving area or guiding system of crate mould must be very precise machining processed. Any hand working on it is not acceptable.
