Dome sheet size and tolerance

Tuesday, February 1st, 2011

Some people may are not very understanding the max size and tolerance of dome sheet, I explain more detial as below:

1, The max. size of dome sheet can do 90*90mm by laser cutting, for larger it should be set up tooling. Because of the high cost of mold, many customers do not understand, in fact, that’s the cost of the mold. If customers really do not want to set up model, it’s the best to be divided into two parts,the effect is the same, but when the assembly is divided into two times only.
2, Dome sheet tolerance, the laser cutting is: +/-0.15-0.20mm; the mold: +/-0.10mm.
