Development and practical application of porous cast (high-quality sand-cast aluminum alloy).

Improvement of the quality of sand-cast aluminum and its application to vacuum components and others.

The high-quality aluminum castings "Poreless Cast," realized through pore minimization technology, greatly expand the applications of castings. 【Features】 1. Issues with aluminum machined parts and the benefits of casting The characteristics of aluminum castings allow for the supply of near-net-shape parts, resulting in less material waste and reduced processing time compared to machined parts made from plates or blocks, enabling cost reduction and shorter delivery times through casting. 2. Characteristics of self-hardening sand mold aluminum casting and conventional issues The self-hardening sand mold casting method is an excellent casting technique that can efficiently produce small items weighing less than 1 kg to large items over 2 tons at low cost. 3. Improvement of internal quality in sand mold aluminum castings (development of Poreless Cast) Through improvements in various technological elements and the development of new process technologies, it has become possible to prevent internal defects in sand mold aluminum castings and significantly enhance internal quality. 4. Practical application of Poreless Cast (high-quality sand mold aluminum casting) parts By reviewing the various technological elements in sand mold aluminum casting, it has become possible to manufacture sand mold aluminum castings (Poreless Cast) with extremely few internal defects and excellent internal quality.
