Common Questions About Our Products
We can produce castings ranging from 5 kg up to 150 kg per piece, depending on the design complexity and molding line requirements.
Developing new pattern tooling and preparing first-article samples takes approximately 3 to 4 weeks, followed by sample inspection and approval.
Our standard sand castings achieve ISO 8062-3 Grade DCTG 8 to DCTG 10 tolerances. Fully machined components are held to the tight drawing tolerances specified by the customer, often down to ±0.01 mm.
Yes, our medium-frequency induction furnaces allow us to formulate custom chemical compositions to meet specific international standards or unique OEM material specifications.
Yes, we offer both rough machining and high-precision finish machining (turning, milling, drilling, tapping) in our in-house CNC machining division.
