The multi-station automatic cold forging machine is an advanced forming equipment characterized by automation, precision, and high technological integration, widely applied across various industries in China. Globally, however, several countries such as Russia, Germany, Switzerland, the United States, and Japan lead the world in the production and technological advancement of cold forging machinery.
Germany, for instance, began utilizing cold forging processes for cartridge case production during World War II. After decades of development, the technology has matured significantly. Russia also started early research in this field, having developed its first combined cold forging machine as early as 1935.
By the 1940s, West Germany was already producing multi-station automatic cold heading machines. Today's advanced models integrate information control and oil mist treatment systems, representing a qualitative leap in cold heading technology.
The United States is widely regarded as a global pioneer in the design, development, and manufacturing of cold forming equipment. Notably, the FXP85PXL cold heading machine developed by National Machinery Company can achieve a forming force of 550 tons, a cutting diameter of 34 mm, and a discharge length of 360 mm.
Japan's cold forging technology has progressed rapidly alongside its automotive industry. Sakamura Machinery Co., Ltd. has introduced the world's largest cold forging machine, weighing 100 tons, capable of cutting blanks with a diameter of 38 mm and a maximum processing length of 430 mm.
Swiss cold heading machines have also reached unprecedented levels in terms of part diameter and productivity. The Hartb BKA series of metal cold heading machines can produce parts with diameters ranging from 28 to 64 mm and a cutting diameter between 14 and 36 mm.
In recent years, cold heading technology in China has advanced rapidly, achieving comprehensive improvements in automation, manufacturing capability, processing precision, production efficiency, and cost control.
