Why Choose Our Investment Casting Service?

1. Exceptional Precision and Detail

Investment casting allows for the production of parts with complex shapes and thin walls that are difficult to achieve with sand casting. Our process ensures a smooth surface finish (Ra 3.2 - 6.3) and high dimensional accuracy, significantly reducing the need for secondary machining.

2. Scalable Production Capacity

Equipped with advanced automation lines—including Japanese horizontal and DISA vertical molding lines—we maintain an annual capacity of 6,000 to 8,000 tons. Whether you need low-volume prototypes or high-volume production, we deliver on time.

3. Integrated Surface Finishing

We offer a variety of in-house surface treatments. Every part undergoes rigorous impact and salt spray testing to ensure the coating remains durable and corrosion-resistant in harsh environments.

4. Lifelong Quality Assurance

Quality is our lifeline. Our QC team monitors every stage, from molten metal analysis to final CMM inspection. We stand behind our products with lifelong quality assurance, ensuring your supply chain remains stable and worry-free.
