1, the use of 304 stainless steel, product material to ensure. Use at room temperature never rust.
2, 2.5mm thick steel, not easy to change.
Deep drawing forming process
Deep drawing is a kind of stamping technology of hollow part which is made by using special tool to cut or cut open hollow parts.
The characteristic is that the plate is driven by the convex die, which can flow into the die, that is to rely on the material flow and elongation rate.
Bulging forming process
Expansion is the use of mold forced blank thickness reduction and surface area increases, in order to obtain the geometry of the parts stamping process.
The characteristics of blank holder was crushed to death, not to flow into the die, completely rely on the extension of material forming.
Flanging is used to mold blank on the hole edge or outside
A processing method for stamping edge vertical edges, in the middle stage of flanging, namely punch below material has not been completely transferred to the side before, if you stop the deformation, forming will be shown on the right, this process method called reaming, production and application are also common.
