Precision Custom Metal Casting Services

Costs depend on the type of process, materials, part complexity, and batch size. Typically, mold development costs are a one-time investment, and the cost per unit decreases significantly as batch size increases. Die casting is suitable for reducing costs in high-volume production, investment casting is suitable for high-precision small-batch production, and sand casting has the lowest mold costs and is suitable for prototyping or small-to-medium-volume production. We offer free quote evaluations; we recommend uploading drawings or 3D files to obtain an accurate quote.

This is primarily determined by three factors: ① Precision and surface quality requirements—investment casting offers the highest precision and is suitable for complex, thin-walled parts; ② Production volume and lead time—die casting is highly efficient and suitable for runs of 10,000 units or more; ③ Material—iron-based and copper-based alloys are commonly cast using sand molds, while aluminum, zinc, and magnesium alloys are suitable for die casting. Our engineering team can provide free process recommendations based on your drawings.

Porosity and shrinkage are the most common quality issues in casting. We reduce residual gases in the mold cavity through vacuum-assisted filling, combine this with real-time spectrometer monitoring for precise control of alloy composition, and optimize the gating system and cooling rates. By addressing these factors at the process source, we maintain internal defect rates at the industry’s lowest levels. X-ray or ultrasonic inspection reports are provided for every batch of castings.

Key design considerations include: setting appropriate draft angles (typically 1°–3°), avoiding localized wall thickness that could cause shrinkage cavities, ensuring smooth wall thickness transitions to minimize hot spots, and allowing for necessary machining allowances. We offer DFM (Design for Manufacturability) review services to help you identify and optimize potential design risks before tooling, thereby saving on rework costs later.

Yes. We offer one-stop post-processing services, including CNC precision machining, deburring, sandblasting, anodizing, electroplating, and coating, ensuring that castings meet assembly or end-use requirements directly, eliminating the need for customers to seek separate secondary processing suppliers.
