Casting FAQ
What quality control measures are implemented in your casting process?
Our casting production follows rigorous quality control protocols including X-ray inspection, ultrasonic testing, chemical composition analysis, and mechanical property testing. Each batch undergoes dimensional verification using CMM (Coordinate Measuring Machine) to ensure compliance with technical drawings. We maintain ISO 9001 certification and provide material test certificates (MTC) with all shipments.
How do you handle complex casting geometries?
For intricate casting designs, we employ advanced CAD/CAM modeling combined with simulation software to predict and prevent potential defects. Our foundry utilizes precision sand casting, investment casting, and die casting methods depending on part complexity and volume requirements. Complex internal cavities are achieved through carefully designed cores and specialized mold-making techniques.
What post-processing options are available for cast components?
We offer comprehensive post-casting services including heat treatment (annealing, quenching, tempering), surface finishing (shot blasting, polishing, painting), and machining operations (turning, milling, drilling). Secondary processing can achieve dimensional tolerances up to IT7-IT8 grade and surface roughness as low as Ra 0.8μm. All post-processing is performed in-house under controlled conditions.

More Casting Questions Answered
What is the typical tooling cost for custom casting projects?
Tooling costs vary significantly based on part complexity and annual volume requirements. For sand casting, pattern costs typically range $1,000-$5,000 for medium-sized components. Permanent mold tooling may cost $10,000-$50,000 depending on cavity complexity. We offer amortization options where tooling costs are spread over initial production orders.
How does your casting pricing structure work?
Our casting pricing considers four main factors: material costs, labor hours, tooling amortization, and secondary processing requirements. Volume discounts apply at 500+, 1,000+ and 5,000+ quantity breaks. We provide detailed quotations breaking down all cost components and offer value engineering suggestions to optimize part design for cost efficiency.
What documentation accompanies your castings?
Standard documentation includes material test certificates, inspection reports, and certificates of conformity. For critical applications, we can provide additional documentation such as radiographic test reports, heat treatment charts, and full traceability documentation from raw material to finished component.
