FAQ

 

Q: What information do you need to provide a quote?
A: For the most accurate quote, please provide:

2D drawings (PDF/DWG) or 3D files (STEP, IGS, X_T).

Material specification (e.g., AISI 316L, A356-T6).

Annual volume forecast (for pricing tiers).

Key quality requirements (tolerances, surface finish, NDT needs).

Any applicable industry standards (e.g., ASTM, MIL, DIN).

Q: What is your typical Minimum Order Quantity (MOQ)?
A: We are highly flexible. We accept prototype orders (as low as 1-10 pieces) for design validation. Production MOQ depends on part size and complexity but typically starts around 500-1,000 pieces for a sustainable run. We welcome discussions for any quantity.

Q: What tolerances can you hold?
A: Standard linear tolerances are ±0.13mm for the first 25mm, ±0.03mm per additional 25mm. Tighter tolerances are achievable on critical dimensions, often through selective secondary machining. Angular tolerances are typically ±0.5°. We will specify achievable tolerances in our DFM report.

Q: What quality certifications do you have?
A: We are ISO 9001:2015 certified. Our processes and quality management system are designed to meet the stringent requirements of industries such as aerospace, medical, and automotive. We can manufacture parts compliant with relevant standards like ASTM, AMS, and DIN.

Q: Can you provide material certifications and test reports?
A: Yes. We provide Mill Certificates for raw materials and Final Test Certificates for castings, which can include chemical composition (from spectrometer), mechanical properties (from separately cast test bars), hardness, and NDT results.

Q: How long does it take to make samples?
A: For new projects, the typical lead time for first samples (prototypes) is 4-6 weeks after order confirmation. This includes:

Tooling design & manufacturing (2-3 weeks)

Wax pattern production & shell building (1 week)

Casting, finishing, and inspection (1-2 weeks)

Q: What is the lead time for mass production?
A: After sample approval, typical mass production lead time is 8-12 weeks for the first batch, depending on order quantity and complexity. Subsequent batches can be produced more quickly.

Q: How do you handle shipping and export?
A: We are experienced global exporters. We package parts securely (often using vacuum sealing for corrosion-sensitive parts) in export-approved wooden crates or boxes. We handle all export documentation and can ship via air freight or sea freight (FCL/LCL) based on your preference.

Q: What if I have a problem with the parts received?
A: Customer satisfaction is paramount. Please notify us within 7 days of receipt with clear photos and descriptions of any issue. Our quality team will investigate immediately. If the issue is due to our manufacturing process, we will arrange for replacements, rework, or credit as appropriate.
