Frequently Asked Questions (FAQ)
Q1: What is your minimum order quantity (MOQ)?
A: We offer highly flexible MOQs. We welcome prototype orders (even single pieces) for testing and development, and efficiently scale up to large-volume production runs.
Q2: What file formats do you accept for quoting and production?
A: We prefer 3D CAD files in STEP or IGES format for accurate quoting and machining. We also accept 2D drawings in DWG, DXF, or PDF format. SolidWorks native files are also acceptable.
Q3: Can you handle complex 5-axis machining?
A: Yes, we have advanced 5-axis CNC machining centers capable of producing highly complex geometries with tight tolerances in a single setup, reducing lead times and potential errors.
Q4: Do you provide material certifications?
A> Yes, upon request, we can provide Material Test Reports (MTRs) or Certificates of Conformance (CoCs) for the raw materials used in your parts, ensuring traceability and compliance.
Q5: How do you ensure quality control?
A> Quality is integral at every stage. We perform in-process checks during machining and conduct comprehensive final inspections using calibrated equipment like CMMs, height gauges, micrometres, and surface testers. First Article Inspection (FAI) reports are available.
Q6: What is your typical lead time?
A> Lead time depends on part complexity, quantity, and surface finishing requirements. Prototypes can often be shipped within 5-7 days. Standard production orders typically range from 10-15 days. Expedited services may be available.
Q7: Do you offer design assistance?
A> Absolutely. Our engineering team provides complimentary Design for Manufacturability (DFM) analysis on your submitted designs. We suggest optimizations to reduce costs, improve functionality, and enhance manufacturability.
Q8: What are your payment terms?
A> Standard terms include T/T (Bank Transfer) with 50% deposit before production and 50% balance before shipment. We can discuss other terms like L/C for established customers.
