Suzhou Jincheng Precision Die Casting Co., Ltd: Diversified Casting Process Layout, Leading Industry Technology Innovation

Suzhou, 7 May 2025

(hereinafter referred to as ‘Jincheng Precision’) as a leading enterprise in the field of domestic aluminium alloy die casting, in recent years, while consolidating the advantages of semi-solid rheological casting technology, actively expanding the diversified casting process system, cold chamber low-pressure casting, gravity casting, such as the research and development of new processes and application of the significant progress, further enhance the comprehensive competitiveness of the company in the field of precision casting. Further enhance the company's comprehensive competitiveness in the field of precision casting.

A technological breakthrough: cold chamber low-pressure casting to achieve efficient production

Jin Cheng Precision rely on its strong R & D capabilities, the traditional cold chamber die-casting technology and low-pressure casting process depth integration, the development of a new generation of fully automatic cold chamber low-pressure casting production line. The technology through precise control of metal liquid filling pressure and speed, significantly reduce the casting of internal porosity and shrinkage defects, especially suitable for new energy automotive parts (such as motor shell, controller box) and communication equipment structure parts production of the strict requirements of airtightness.

At present, the company has built a number of cold chamber low-pressure casting demonstration line, combined with self-developed numerical simulation platform to optimise the mould design and process parameters, so that the casting qualification rate is stable at more than 98%, the production efficiency of 20% higher than the traditional process.

Second, gravity casting process: enabling the manufacture of complex structural components

Aiming at aerospace, medical equipment and other fields on the demand for complex thin-walled parts, Jin Cheng Precision in the field of gravity casting continued to make efforts. Through the introduction of high-precision mould temperature control system and a new type of aluminium-silicon alloy materials, the company successfully solved the gravity casting prone to pouring uneven, coarse grain and other issues. Its production of aviation hydraulic shells and medical equipment brackets and other products, with excellent mechanical properties and surface finish, has passed the certification of a number of international customers and achieve batch delivery.

Technology synergy: extrusion casting and digital upgrading

In addition to cold chamber low pressure and gravity casting, Jincheng Precision has also made breakthroughs in extrusion casting technology. The company developed ‘rheological die casting and extrusion casting technology’ is applied to new energy vehicles three-in-one motor shell production, through the high-pressure shrinkage process significantly improve the parts density, product thermal conductivity than the traditional die casting increased by more than 15%.

At the same time, Jincheng Precision and enterprise know the space of science and innovation to promote the construction of digital factory, the use of big data analysis to optimise the casting process parameters, to achieve the whole process from design to production of intelligent management, and further shorten the development cycle of new products by more than 30%.

Fourth, the market and future prospects

Jincheng Precision's new process layout has begun to bear fruit, its product coverage of new energy vehicles, communication base stations, photovoltaic energy storage and other high-growth areas, and with sunlight power supply, Weifu Hi-Tech and other leading enterprises to reach a strategic cooperation. 2024 the company's operating income exceeded 690 million yuan, the market share continues to climb.

In the future, the company plans to invest in the expansion of Xuzhou production base, new gravity casting line, and deepen the cooperation with universities to promote multi-process integration and innovation, the goal is to achieve the transformation of the ‘full process chain coverage’ of the precision casting solutions provider before 2026.
