What casting buyers screen on
An engineer sourcing castings needs to know which alloys you pour, which casting methods you run, the weight and dimension range you handle, the tolerances you achieve, and whether you can produce or hold patterns. Without those, a foundry cannot be evaluated at all, and the enquiry goes to one that published them. Quality testing capability is the second filter for anything structural.
What we build for a foundry
First, alloy range and casting methods with weight and dimension limits, which is the qualification an engineer performs first. Second, tolerance and finishing capability, including machining if you offer it. Third, pattern making and storage, since that determines the cost of a repeat order. Fourth, quality testing and certification — spectro, radiographic, mechanical — which is what lets you serve industrial buyers rather than repair work.
