In recent years, with the continuous improvement of the industrial chain of China's precision castings industry and the continuous improvement of technology, downstream demand areas have shown an increasing demand for precision castings. However, there are still many problems in the traditional precision casting production process, which plagues a large number of precision casting manufacturers. In this market background, with its accumulated experience in the foundry industry over the years, and the use of its high-performance light-curing 3D printing equipment, it has independently launched a new set of integrated systems for rapid casting (Quick Casting) application solutions. It can effectively solve the pain points in the traditional precision casting process, while ensuring the production of high-quality castings.

Rapid precision casting technology is the perfect combination of light curing rapid prototyping technology and traditional investment precision casting technology. Light curing rapid prototyping technology can be integrated into the investment casting process seamlessly.

Traditional investment precision casting is a near-net-shape forming process. Its castings have high dimensional accuracy, complex structures, and strong adaptability to materials. They are widely used in the aerospace field where high added value focuses on weight reduction. The process flow is through the steps of making metal molds, making wax molds, making trees, hanging blasting and blasting shells, steam dewaxing, mold shell roasting, pouring, post-processing of castings, and casting detection. Traditional precision casting technology has a long mold manufacturing and shaping cycle, high cost, and cannot quickly respond to market demand.

The light-curing rapid prototyping technology (SLA) involved in rapid precision casting technology is an advanced manufacturing technology with high flexibility. The CAD model of the part can directly drive the equipment to complete the molding of the part prototype, and apply it to the direct manufacturing of precision casting models , Can greatly improve the flexibility of investment precision casting and achieve rapid casting. Compared with other rapid prototyping methods for investment casting (such as SLS, FDM, etc.), it has great advantages in terms of dimensional accuracy and surface quality.
