What is the law of plastic deformation of sheet metal processing materials

Sep 26,2021

Features of precision die castings:

Dimenionalaccuracy.surace accuracy,.thin wall castings have high dimensionalacuracy. genfally cquivalent to grade6 ~7.even up to grade 4y surface finih isgood.gener-ally equivalent to grade 5-. srength and hardes are higher. and the srength i generall higher thn sand typeCasthg is increased by 25 -30% but the elongaton s reducedby about 70O%. the size is stable and the interchangeablityis good;,thin-walld complex catings can be diecast For example the minimum wl hickmess of urentins llydie castings can reach 0.3mm; aluminum alloy castings can reach 0.5mm, the minimum cast hole diameter s 0.7mm;.the minimum pitch is 0.75mm

Massproduction. The machine has high productvity and can be mult-cavity. for example the domestic is horizontal cold air diecastig machine can diecat 60 to Tootimes in an average of eight hours and the smel ot chamber diecasting machine can die in an average of 30 to 700 times every eight hours,The diecatng mode hs along sevce lfe.Once diecasting model and die-castin ll y the sevice liecan reach hundreds of thousands of times, even milion o times easyto realize mechantratonand automation.


what ls Precision Metal stamping ?(图1)


Economic beneFisDue to the precsedimensions of the diecasting parts the surace s smooth and so on Geneall, tisused drectly without mechancal processing, or the pocessing youme lsvery small soi not only improves the metal u;liatonrat, butasoreduces a ot of processing equipment and working hours the cating pice seasy.the combi.nation of die casting can be used to other metal or non-metal materials . it saves both assembly time and metal.

Surface treatment: easy to do various surface treatments, such as electroplating. plastic spraying.etc.
