Hi guys I am looking at doing some moulds for our friend on our machining centre - we mainly do high end 3D production parts and injection moulds. I am interested in making Lrtm moulds but cannot find much info out there on sizing the flanges. Part will be 5mm thick with some fairly complex geometry on the B mould side. Around 1m long and 250mm wide by around 200 deep. It is a remote control boat with pockets inside for the batteries motors etc. Can anyone give me some info on how the flanges are worked out?
