faq
What are the minimum and maximum sizes you can cast?
Our investment casting process can produce parts ranging from a few grams up to a maximum of 50kg per piece. For special requirements outside this range, please contact us for a technical evaluation.
What tolerances can be achieved with investment casting?
Typically, our investment castings can achieve dimensional tolerances of CT5-CT7 level (refer to ISO 8062 standard). The exact tolerance depends on the part's geometry and size.
What are the typical lead times?
For new tooling, it typically takes 4-6 weeks. Once the tooling is ready, the first samples usually take 2-3 weeks. Production lead times vary based on order quantity.
How do you ensure the quality of castings?
We implement strict quality control throughout production, including incoming material inspection, in-process control, and final inspection. We can provide dimensional inspection reports and material certificates, and perform NDT like X-ray or dye penetrant inspection upon request.
What information do I need to provide for a quote?
For an accurate quote, please provide 2D drawings (PDF or DXF) and/or 3D models (STEP or IGES), along with the required material, annual quantity, and any special technical requirements.
