aluminum die casting parts are widely used in the surface treatment of non-ferrous metal die castings, castings, aluminum profiles, auto parts, machinery manufacturing, hardware, and pump valve industries. Mainly focus on removing the product surface oxide scale, edge surface burr, surface roughening, matt fruit, leveling strengthening, rust removal treatment. Stainless steel shot is commonly known as stainless steel wire cut shot. It is refined by wire drawing, cutting, rounding and other processes. The appearance is bright, rust-free, and bead-shaped.
High-precision special-shaped copper strip: high-precision copper strip for the special-shaped frame of the transistor, generally a high-strength and high-conductivity alloy containing phosphorus and silver. The section is composed of thick and thin sides. The thick side is 1.27 mm and the thin side is 0.38 mm. 68 mm, the length is greater than 200 meters, three production methods, namely pass rolling, milling chips, high-speed forging to produce special-shaped section billets, aluminum die casting parts are high-precision rolling, the key technology is high-precision rolling, the thickness must be guaranteed The extension coefficient of the edge and the thin joint is equal, otherwise the special-shaped strip type cannot meet the needs of users.
Internal oxidation dispersion strengthened oxygen-free copper: Electric vacuum devices require oxygen-free copper, which does not deform during hydrogen gas welding at 930°C. It is difficult to achieve using alloying methods. Oxidized particle dispersion strengthening methods are commonly used at home and abroad, and oxidized particle AL2O3 is commonly used.
Large-area miscellaneous section special-shaped custom die casting technology: In order to meet the requirements of the construction of copper castings, especially giant bronze statues, it is necessary to cast large-area, thin-wall special-shaped copper castings. The area of aluminum castings can reach 6 meters square, and the thickness of wall panels is 6-10 mm. It is difficult to use general sand casting methods. In recent years, resin sand modeling and investment casting have been widely adopted and developed at home and abroad. After the molten metal is poured into the sand mold, the model is ablated and filled with molten metal. It has a short process, The casting surface is smooth and the artistic image is perfect.
