Frequently Asked Questions (FAQ)
Q1: What is your minimum order quantity (MOQ)?
A: MOQ depends on part complexity and size. Typically, it's 500–1000 pieces for new molds. For existing molds, MOQ can be as low as 200 pieces. We also accept small trial orders for sample verification.
Q2: How long does it take to produce a new mold?
A: Mold development usually takes 25–40 days after design approval, depending on complexity. We provide design for manufacturing (DFM) feedback to optimize mold life and casting quality.
Q3: What quality certifications do you have?
A: We are ISO9001:2015 certified. We also meet customer-specific requirements and can provide material certificates, dimensional inspection reports, and defect rate statistics upon request.
Q4: Can you handle custom designs or drawings?
A: Yes, we offer full OEM/ODM services. Send us your 2D/3D drawings (STEP, IGES, PDF) or samples, and we will provide a solution including material selection, tolerance analysis, and cost estimation.
Q5: What are your payment terms?
A: Common terms include T/T (30% deposit, 70% before shipment) and L/C. For long-term partnerships, open account or other terms may be negotiable.
Q6: Do you offer free samples?
A: We can provide samples from existing molds for evaluation; you only need to cover shipping cost. For new custom samples, a small sampling fee applies, which is refundable when you place a bulk order.
Q7: How do you ensure product consistency in mass production?
A: We follow a strict process control plan: incoming raw material inspection, in-process parameter monitoring, and final inspection (dimension, appearance, hardness, porosity). Statistical process control (SPC) is applied for key characteristics.
Q8: What is your typical lead time?
A: For regular orders without new mold, lead time is 15–25 days after deposit. For orders with new molds, add 25–40 days. We always communicate production schedules and can expedite for urgent needs.
