Stainless Steel Casting Process

Stainless Steel Investment Casting
By fully adopting advanced silica sol shell-making technology, we have significantly improved the accuracy, surface finish, and overall performance of our stainless steel castings. Additionally, we have introduced a shell-making process combined with coated sand to further optimize production efficiency and ensure the highest quality standards. This process allows us to produce stainless steel castings with intricate designs and exceptional precision, making them ideal for demanding industrial applications.

Stainless Steel Sand Casting
In the sand casting process, we select sand mold materials, such as resin sand and ceramsite sand, based on customer performance requirements. Ceramsite sand, known for its uniform particles and excellent refractory properties, is particularly suitable for high-temperature and challenging casting applications. We strictly follow post-inspection and recycling processes to ensure the quality of the sand molds and the stainless steel castings produced. Our goal is to consistently meet customer demands for high-quality and reliable stainless steel castings.

Stainless Steel Shell Mold Casting
Our shell mold casting production line is equipped with the latest imported machinery, including eight automated units capable of manufacturing stainless steel castings weighing up to 200 kg. With a monthly production capacity of 800 tons, our experienced team ensures both efficient production and rigorous quality inspection. This allows us to deliver stainless steel castings that meet the highest standards of precision, durability, and performance for a wide range of industrial applications.

Heat Treatment
Heat treatment is a process that alters the properties of metals or alloys by controlling heating and cooling. This enhances hardness, strength, and corrosion resistance, ensuring that stainless steel castings meet the required performance standards. Our primary methods include normalizing, annealing, and tempering, tailored to optimize the mechanical properties of stainless steel castings for various industrial applications.

Post-Machining
Although stainless steel precision castings can achieve high dimensional accuracy and surface finish, some applications require additional machining to meet strict tolerance and surface finish requirements. Our professional machining services enable us to manufacture stainless steel castings with complex geometries and intricate details while maintaining high precision and accuracy. Equipped with a full range of machining equipment, from manual turning and milling to advanced CNC machining services, we ensure that every stainless steel casting meets exact specifications.

Surface Treatment
To enhance the performance and appearance of stainless steel castings, we apply various surface treatment methods, including rust-proof oil coating, painting, sandblasting, chemical treatment, anodizing, and electrophoresis. These treatments improve corrosion resistance, enhance wear resistance, and provide a polished finish, ensuring that our stainless steel castings deliver both durability and aesthetic appeal.
