Compared with ordinary liquid casting, semi-solid casting is widely used in Europe and America due to its reduced solidification shrinkage, high dimensional accuracy of castings, good appearance quality and excellent mechanical properties of castings. It is considered to be the most promising near net shape in the 21st century and one of the new material preparation techniques.

Recently, the 1600T high solid phase large-scale thin-wall aluminum alloy structural parts production line jointly developed by Shenzhen Yinbaoshan New Die Casting Technology Co., Ltd. and Research Institute of Engineering Technology Co., Ltd. completed the trial operation and successfully produced the world's first high solid. Phase semi-solid automotive shock tower.

The main line of the production line adopts the DCC1600 semi-solid casting special die-casting machine developed by LKGroup's Shanghai Yida Machinery Co., Ltd. according to the characteristics of high solid phase semi-solid die casting process. It has the characteristics of high production efficiency, low energy consumption and prolonged die life. . At present, aluminum alloy high-solid phase semi-solid thin-wall automotive shock absorber tower castings have been successfully produced.

The product dimensions are 417.4×444.6×469.8mm, the maximum wall thickness is 5.5mm, the minimum wall thickness is 2.5mm, and the average wall thickness is 3.08mm. In terms of performance, the elongation is 10%, the yield strength is 180 MPa, and the tensile strength is 250 MPa.

Industry insiders pointed out that this has a milestone significance in the development of aluminum alloy high solid phase semi-solid die casting technology, which has changed the industry's understanding of high solid phase semi-solid die casting production of complex thin-wall die-casting parts. Yinbaoshan is expected to become domestic. The first enterprise completed the industrial production of aluminum alloy high solid phase semi-solid thin wall die castings.

Nowadays, in order to improve the energy-saving level of passenger cars and alleviate energy and environmental pressures, the lightweight of automobiles has become the trend of world automobile development. The semi-solid die-casting technology provides an important direction for the realization of “aluminum-based steel” and lightweight manufacturing of automobiles. This technology has shown great development potential in improving the microstructure and performance of aluminum alloy castings, controlling defects, and achieving near-final forming. Widely used in high-speed rail, commercial vehicles, new energy bus and other fields, with broad prospects.
