In recent years, as ChinaDongguan Precision CastingWith the continuous improvement of the industry chain and the continuous improvement of the technical level, the downstream demand field is showing a trend of increasing demand for precision castings. However, there are still many problems in the traditional precision casting production process, which plague a large number of precision casting manufacturers. Under such a market background, relying on its years of accumulated practical experience in the foundry industry, using its high-performance light-curing 3D printing equipment, independently launched a set of integrated system 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 casting technology. Light curing rapid prototyping technology can be integrated seamlessly into the investment casting process.

Traditional investment casting is a near-net forming process. Its castings have high dimensional accuracy, complex structure, and strong material adaptability. 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, assembling trees, hanging slurry and sandblasting shells, steam dewaxing, shell firing, pouring, casting post-processing and casting inspections. traditionalDongguan Precision CastingThe technical mold manufacturing and shaping cycle is long, the cost is high, and it is not able to 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 and manufacturing of the part prototype, and it is applied to the direct manufacturing of precision casting models. , Which can greatly improve the flexibility of investment casting and realize rapid casting. Compared with other rapid prototyping methods used in investment casting (such as SLS, FDM, etc.), it has great advantages in terms of dimensional accuracy and surface quality.

Through years of application practice and technical summary in the foundry industry, a set of systemic rapid precision casting application solutions has been developed. The application advantages include:

Eliminates the process of making molds and wax patterns

Fast molding speed

Realize small batch production and prototype trial production

Realize the complexity of casting design

Reduce casting production costs

Excellent casting properties

byPrecision cast steelFor example, the impeller, which is a common component of precision castings, is mainly used in the military and civil aviation fields, and the casting process has certain difficulties. In the early stage, using its Lite 600HD-D stereo light curing 3D printing equipment to quickly replace the wax mold in the traditional investment casting process, eliminating the need for the production of metal molds and wax production involved in the traditional investment casting process. The two processes of moulding not only save costs, but also speed up the production cycle. The entire printing time is only 5 hours, 15 minutes and 26 seconds.
