Sand Casting Expertise
We specialize in several sand casting processes to meet your part complexity, size, and production volume.
Green Sand Casting
An economical method using wet, clay-bonded sand molds. Best for large or simple parts with moderate surface finish and fast mold turnaround.
Resin Sand Casting
Uses chemically bonded sand for stronger molds and dimensional accuracy. Suitable for medium-to-large parts with better surface finish.
Dry Sand Molding
Involves baking the sand mold to remove moisture, improving heat resistance and stability. Ideal for steel and high-temperature alloy castings.
CO₂ Sand Molding
Hardens sodium silicate sand with carbon dioxide gas for rapid mold setting. Great for prototyping and short runs, with reduced tooling time and cost.
What is Sand Casting?
Sand casting is a mature and widely adopted metal forming process in which molten metal is poured into a single-use sand mold. After cooling and solidification, the mold is broken away to reveal the final part. The full workflow typically includes pattern making, mold formation, metal pouring, cooling, and post-processing, offering high flexibility to meet diverse manufacturing needs.
One of the core advantages of sand casting is the elimination of costly permanent tooling, making it particularly suitable for customized designs, complex geometries, and low-to-medium volume production. Sand casting is commonly used for producing pump and valve housings, machinery frames, and automotive powertrain components, especially in industries like automotive, industrial equipment, heavy machinery, and general manufacturing, where cost-efficiency and structural adaptability are essential.

Sand Casting FAQs
Have questions about Sand Casting? We’ve compiled a list of frequently asked questions to help you understand our processes better.
Our standard lead time is typically 2–4 weeks for tooling development and an additional 1–2 weeks for casting production, depending on part complexity, order volume, and required post-processing. For urgent projects, we also offer expedited options—just let us know your timeline when requesting a quote.
We support both small-batch and large-scale production. For new custom parts, the MOQ typically starts at 100 pcs, but we are flexible depending on your project requirements. Please send us your drawings for evaluation.
We work with a wide variety of metals for sand casting, including gray iron, ductile iron, aluminum alloys, and stainless steel. Our engineers can help you select the most suitable material based on mechanical properties, weight, corrosion resistance, and cost.
Yes, we offer full in-house pattern and mold making services. For rapid development, we can also provide 3D-printed sand cores or quick cast samples for prototyping and testing before mass production.
Yes, we offer a full range of post-processing services including CNC machining, heat treatment, shot blasting, powder coating, and surface finishing to meet your final part requirements.
Absolutely. Our engineering team will review your part design and provide suggestions to improve castability, reduce defects, and optimize cost. You’re welcome to upload your CAD drawings for a free DFM (Design for Manufacturability) evaluation.
We follow strict quality control protocols including sand testing, dimensional inspection, material verification, and NDT (non-destructive testing) when required. All parts are traceable and meet ISO 9001 standards.
Die casting suits high-volume, tight-tolerance parts in light alloys. Sand casting is better for large, low-volume parts or high-melting-point metals. Sand casting cost is typically lower for prototypes or limited runs.
