When custom moulds, the mould tooling equipment is very important, when the moulds have optimal mould design, they need precision tooling machines to make the precise machining. On the other hand, if the machines are very precise, but we do not care the operation and process of the machining, we cannot get the correct dimensions that we want.
Below is the example:
we can use a new Taiwanese CNC milling machine to approach an 1000mm length part with the tolerance ﹢/- 0.03mm. But many mould company they cannot realize this precision. It is because of the operation and process.
We always think that the grinding machines is suitable for the plate surface finishing, but if you know the process of the grinding machines, a flat grinding machine can also realize the curve shape or some narrow channel’s grinding.
All the components in the mould, they were made by different kinds of machining process, for example the round parts, the best way should be made by lathe machine and then round grinding machining. Your cannot use high speed milling machines to get the same result. This we call it the components machining process. It is talked about to choose which type of machining, which machining is in the beginning and which is later. It is also talk about which critical points we need to take care, sometimes is workshop temperature, sometimes is force from inside of the steel (metal)…
So when you custom moulds from a mould company, please check their machining capacity, the machining capacity is combined with machining managements, machining process knowledge…
