What process performance are required to precision stamping die
Precision electronic technology co. , LTD. , founded in 2008, is a professional design and manufacture of stamping mould and precision stamping of ODM/OEM professional manufacturers.
Professional stamping production and processing precision terminal, shell parts, precision hardware such as stainless steel shrapnel, etc.
Precision stamping die is the indispensable process in stamping processing equipment, mold relationship by the quality of the precision stamping parts, so for mould manufacturing have high requirements, to ensure the manufacturing quality of mould, reduce the production cost.
Mold making materials should have the following process performance: forgeability: with low hot forging deformation resistance, stamping parts and plastic is good, the forging temperature range wide, cold forging crack crack and precipitation carbide network tend to be low.
Cutting machining, cutting dosage, low dissipation of cutting tool and the processing surface roughness is low.
Annealing craft: the spheroidizing annealing temperature range wide, annealing hardness is low, and the fluctuation range is small, spheroidization rate is high.
Hardenability: after quenching is uniform and high surface hardness.
H: after quenching can get deeper hardening layer, the moderate quenching medium can be hardened.
Grinding sex: grinding wheel relatively small loss, no burn limit grinding dosage, insensitive to the quality of grinding wheel and cooling conditions, grinding and grinding precision stamping die crack does not occur.
When heated to high temperature oxidation and decarburization sensitivity: antioxidant bosom can good, decarbonization speed slow, is not sensitive to the heating medium, produce pitting tend to be small.
Mould manufacturing is typically after forging, machining, heat treatment, and several working procedure, the processing difficulty is higher, to the manufacturing material demand is high, should have good processability, to ensure that don't appear in the process of precision metal stamping mould manufacturing process defects, and stable quality.
