Frequently Asked Questions

What is sand casting stainless steel and how does it work?

Sand casting stainless steel is a process where molten stainless steel is poured into a sand mold created by compacting sand around a pattern. The pattern is removed to leave a cavity that is filled with molten metal. After cooling, the sand is broken away to reveal the finished part. This method is ideal for producing complex shapes in various sizes. At Dongguan Jinbianda, we combine this traditional technique with modern controls to ensure consistent quality and dimensional accuracy. Our capabilities include both manual and automated sand casting, allowing us to handle small to large quantities efficiently. The process is cost-effective for both prototyping and production runs, especially for parts with intricate geometries that might be difficult to machine from solid stock.
We offer a broad selection of stainless steel alloys, including 304, 316, 317, 347, 410, 420, 17-4 PH, and duplex stainless steels like 2205 and 2507. Each alloy has distinct properties: for example, 316 provides excellent corrosion resistance in marine environments, while 17-4 PH offers high strength and hardness. Our material experts help you select the optimal alloy based on your application's mechanical, thermal, and chemical requirements. We also provide full material certification and traceability to ensure compliance with international standards. For specialized needs, we can source additional stainless steel grades upon request. This versatility ensures that your sand casting stainless steel parts perform reliably in the most demanding conditions.
Our sand casting stainless steel process can achieve tolerances of ±0.005 inches (0.127 mm) for small to medium-sized parts, with slightly looser tolerances for larger castings. Factors such as part geometry, alloy shrinkage, and mold design influence achievable tolerances. Our engineering team uses simulation software and trial runs to optimize mold design and minimize variability. We also offer secondary machining operations to achieve even tighter tolerances when required. For critical dimensions, we perform thorough inspections using coordinate measuring machines (CMM) and other metrology equipment. By communicating your tolerance requirements upfront, we ensure that your parts meet exact specifications, reducing the need for post-casting modifications.
Yes, we have the capability to produce sand casting stainless steel parts ranging from small components weighing a few ounces to large castings exceeding 500 pounds (227 kg). Our sand casting process is highly adaptable, with custom flask sizes and molding equipment that accommodate various dimensions. We have successfully manufactured large industrial components such as pump housings, valve bodies, and machinery frames. Our team carefully designs gating and risering systems to ensure proper metal flow and solidification, preventing defects like shrinkage or porosity. We also provide CNC machining for large parts to achieve precise tolerances and surface finishes. Whether you need a single prototype or a production run of large castings, we have the expertise to deliver high-quality results.
We provide a comprehensive range of post-processing services to enhance the quality and functionality of your sand casting stainless steel parts. These include heat treatment to improve mechanical properties, CNC machining for tight tolerances, and surface finishing options such as sandblasting, polishing, and plating. We also offer welding and assembly services if your part requires joining with other components. Our quality control team conducts dimensional inspections, material testing, and pressure testing to ensure compliance with your specifications. Additionally, we provide surface treatments like passivation to enhance corrosion resistance. By offering these services in-house, we streamline your supply chain and ensure consistent quality throughout the production process.
