1、Process Introduction | What problems can stamping solve?
High speed mass production: progressive die 200-800 times/min, single shift daily production of 100000-500000 pieces, cost 60-80% lower than machining
Complex three-dimensional shape: a combination of multiple workstations including deep drawing, punching, flanging, and shaping, achieving box body, shell, flange, and reinforcement ribs
High precision dimensions: Precision progressive die ± 0.01 mm, hole position accuracy ≤ 0.02 mm, direct assembly without secondary processing
Excellent surface: Cold rolled sheet surface Ra ≤ 0.8 µ m, galvanized/coated sheet can still maintain its original appearance after stamping
Material saving: Closed material layout, material utilization rate ≥ 85%, suitable for precious metals and stainless steel thin materials
