FAQs
What level of precision and surface finish can investment casting achieve?
Our investment casting process can achieve VDG P690 D1-D2 / ISO 8062-3 DCTG 4-6 precision levels, with typical surface roughness of Ra 3.2–6.3 μm.
For projects requiring tighter tolerances or smoother finishes, we can further improve accuracy and surface quality through precision machining, polishing, and other secondary processes.
Do you support small-batch prototyping? What is your minimum order quantity (MOQ)?
Yes. We support low-volume production and prototypes with no minimum order quantity requirement.
This makes us a good fit for startups, brand owners, and SMEs developing new products or testing new designs. Prototype projects typically take around 3–4 weeks, including mold development.
Can you provide a complete solution from casting to machining and surface finishing?
Yes. Providing a complete manufacturing solution is one of our key strengths.
Simply send us your drawings and specifications, and we take care of the entire process in-house — including mold design, investment casting, CNC machining, heat treatment, and surface finishing such as electropolishing, plating, and coatings.
This allows you to work with one reliable supplier from prototype to final production parts.
What types of customers are you best suited for?
We mainly work with brand owners, product developers, and SMEs that need a reliable manufacturing partner but do not have a complete production system in place.
You focus on product design and market development, while we handle the complete manufacturing process — from material selection and casting to machining, finishing, and final delivery of finished parts.
