In recent years, with the continuous improvement of the industrial chain of China's precision casting parts industry and the continuous improvement of the technical level, the downstream demand field has shown an increasing demand for precision casting parts. However, the traditional precision casting production process still has many problems, which is plagued by a large number of precision casting manufacturers. In this market background, with its years of experience in the foundry industry, using its high-performance light-curing 3D printing equipment, it has launched a new Quick Casting application solution for integrated systems. It can effectively solve the pain point problem in the traditional precision casting process, and at the same time guarantee the production of high quality castings.
Fast precision casting technology is the perfect combination of light curing rapid prototyping technology and traditional investment casting technology. Light-curing rapid prototyping technology integrates seamlessly into the investment casting process.
The traditional investment casting is a near-net forming process. The casting has high dimensional accuracy, complex structure and strong material adaptability. It is widely used in the aerospace field with high added value and weight loss. The process is through the steps of making metal molds, making wax molds, group trees, hanging sandblasting shells, steam dewaxing, shell baking, casting, post-casting treatment and casting inspection. The traditional precision casting technology has a long manufacturing cycle and a high cost, and cannot respond to market demands quickly.
The rapid solidification 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 prototype manufacturing of the part and apply it to the direct manufacturing precision casting model. It can greatly improve the flexibility of investment casting and achieve rapid casting. Compared with other rapid prototyping methods for investment casting (such as SLS, FDM, etc.), it has great advantages in dimensional accuracy and surface quality.
Through years of application practice and technical summary in the foundry industry, a system-accurate rapid precision casting application solution has been developed. The application advantages include:
Eliminated the process of making molds and wax patterns
Mold forming speed is fast
Achieve small batch production and prototype trial production
Achieve the complexity of casting design
Reduce casting production costs
Excellent casting properties
Taking the impeller of the common parts of precision castings as an example, the impeller is mainly used in the military and civil aviation fields, and the casting process has certain difficulties. In the early stage, it used its Lite 600HD-D stereo light-curing 3D printing equipment to replace the wax mold in the traditional investment casting. It eliminates the traditional mold casting process and the production of wax. The two processes of the mold not only save costs, but also speed up the production cycle, the entire printing time is only 5 hours, 15 minutes and 26 seconds.
