The industry standard "Squeeze Casting Machine" proposed by Suzhou Sanji was approved by the Ministry of Industry and Information Technology in 2011. The standard was led and led by Suzhou Sanji, in collaboration with Harbin Jixing Engineering Machinery Co., Ltd., Ningbo Branch of a Chinese scientific research institute, Zhejiang Wanfeng Technology Development Co., Ltd., and other units. After 5 years of effort, the standard was completed and officially released and implemented by the Ministry of Industry and Information Technology on March 1, 2016.
    The process technology of squeeze casting (also known as liquid forging) has a history of more than 40 years in China. However, due to the lack of professional squeeze casting equipment in China for a long time, squeeze casting was mainly achieved using equipment modified from hydraulic presses. This equipment has problems such as simple control, low efficiency, unstable quality, inability to form complex parts, low degree of automation, and narrow process range. At the same time, there are a small number of imported equipment from Ube Japan, but their prices are extremely expensive, and squeeze casting equipment weighing over 800 tons is banned from sale in China. As a result, the backwardness of equipment in China seriously restricts the development of squeeze casting technology. Until 2008, Suzhou Sanji Casting Equipment Co., Ltd. was the first in China to develop the first 350 ton horizontal squeeze casting machine, and in recent years has successfully developed a series of products ranging from 50 to 2500 tons of horizontal and vertical squeeze casting machines. China's squeeze casting technology has achieved rapid development. Today, the development of squeeze casting technology has sparked a trend in the domestic industry and will play an important role in the development of China's basic industries.
    Squeeze casting technology is regarded by industry experts as one of the most advanced casting processes in the field of non-ferrous alloy forming. Its efficient production method and molded parts have high-quality characteristics such as high density, high airtightness, and high performance, which have been recognized and favored by more and more professionals in the industry. This technology will play an increasingly important role in more than 20 industries such as automobiles, communications, and motorcycles. The country has included this process as a very important process technology in the "Energy saving and New Energy Vehicle Manufacturing Technology Roadmap" of the strategic development plan "Made in China 2025", and the country will also strongly support the development of this process technology in the future.
    The formulation and promulgation of this standard is a landmark in the development of China's squeeze casting industry, marking the gradual entry of China's squeeze casting technology into a historical period of standardized and large-scale development.
