Resin sand casting

Resin sand casting: Using resin as a binder, mixed with sand to form a sand mold. Resin sand casting has low mold costs and is suitable for large and complex castings, generally used for machine tools, lathes, large machinery bases, etc.

■ Process Advantages

High flexibility: Suitable for the manufacture of parts with various complex shapes, allowing for flexible adjustment of casting design, easy batch production, and meeting the diverse needs of different customers.

Good surface quality: The surface of the casting is smooth and free of obvious defects, greatly reducing subsequent surface treatment processes, lowering production costs, and improving production efficiency.

High precision: Able to produce castings with high dimensional accuracy, effectively controlling the dimensional deviation of castings and meeting various high-precision engineering requirements.

High production efficiency: Short preparation cycle, the entire process from mold making to casting formation is relatively short, allowing for rapid production, suitable for large-scale and high-efficiency production.

Relatively low cost: Compared to some other casting processes, such as investment casting, resin sand casting has lower equipment investment and production costs, and is more economical.

High sand mold strength: After hardening, resin sand has high strength and rigidity, able to withstand the scouring and pressure of molten metal, not easily deformed or damaged, which helps to ensure the quality of the castings.

■ Application Areas

Automotive manufacturing: Used to produce engine blocks, cylinder heads, transmission housings, brake system parts, etc., precisely controlling the size and shape of castings to ensure the quality and performance of automotive parts.

Aerospace industry: Resin sand casting is often used in the manufacturing of aircraft engine parts and fuselage structural components. By adding alloying elements, the strength and toughness of the castings can be improved to meet the high-performance requirements of the aerospace industry for parts.

Engineering machinery industry: Such as excavator bucket teeth, bulldozer blades, mining equipment parts, etc., resin sand casting can produce high-performance, wear-resistant engineering machinery parts, extending their service life.

Power equipment industry: Can be used to manufacture generator set components, transformer cores, high-voltage switchgear housings, etc., precisely controlling the size and shape of castings to ensure the stable and reliable operation of power equipment.

Shipbuilding industry: Manufacturing of marine diesel engine parts, propellers, hull structural components, etc., resin sand casting can meet the high requirements of ship parts for precision and strength, ensuring the sailing performance and safety of ships.

Rail transit industry: Train wheel hubs, bogie parts, subway car body structural components, etc., resin sand casting can precisely control the size and shape of castings to ensure the smooth and reliable operation of rail transit equipment.
