According to archaeological discoveries, as early as more than 2000 years ago, my country had stamping dies used to make copperware, which proved that ancient Chinese stamping and stamping dies were the world's leading achievements.

In 1953, Changchun No. 1 Automobile Manufacturing Plant established a die workshop for the first time in China. The plant began manufacturing automobile panel molds in 1958. my country began to produce fine blanking dies in the 1960s. After a long road of development, my country has now formed a production capacity of more than 30 billion yuan (excluding statistics from Hong Kong, Macao and Taiwan) of various stamping dies.

The level of stamping die

In recent years, the level of stamping dies in my country has been greatly improved. Large stamping dies have been able to produce a single set of dies with a weight of more than 50 tons. Cover parts for mid-range cars can also be produced in molds. The multi-station progressive die with an accuracy of 1~2μm and a life span of about 200 million times has been produced by many domestic companies. The fine blanking dies with surface roughness reaching Ra≤1.5μm, large-size (φ≥300mm) fine blanking dies and medium-thick plate fine blanking dies have also reached a fairly high level in China.
