Metal stamping is a high-precision, cold-working process used to shape sheet metal into complex parts using progressive dies and high-tonnage presses. At Chenying, we specialize in high-volume, cost-efficient production of custom stamped components for the automotive, electronics, and appliance industries. Our in-house tooling team and ISO-certified quality systems ensure fast turnaround and reliable results.
What is metal stamping?
Metal stamping is a cold-forming manufacturing process that uses dies and presses to shape sheet metal into complex components. It enables operations such as blanking, bending, deep drawing, and embossing—producing high-precision parts at industrial scale.
Commonly fed as coils or sheets, metal material is formed using custom-designed dies that precisely control shape and tolerances. This allows for highly efficient, low-cost, high-volume production with excellent material utilization—making it ideal for the automotive, electronics, home appliances, aerospace, and architectural hardware industries.
Compared to traditional forging or casting, metal stamping preserves material properties while enhancing production efficiency. The accuracy and longevity of the stamping dies are critical to part consistency and quality.
