Q2: Can you provide a sample before mass production?
A: Yes, we offer sample parts from existing molds or from a prototype mold. Sample lead time is usually 7-15 working days, and sample cost is deductible from bulk orders.
Q3: How do you ensure the 300,000 shots mold life?
A: Our molds are made from premium tool steel with hardened cavities and core inserts. We perform regular maintenance and use advanced cooling channels to minimize wear. The 300,000-shot guarantee is based on our manufacturing experience under standard production conditions.
Q4: What is the typical lead time for a new mold and first article?
A: Mold fabrication takes 20-30 working days depending on complexity. First article approval and sample delivery follow within 5-7 days after mold completion. Production ramp-up can be arranged immediately upon approval.
Q5: Can you customize the bobbin dimensions or add special features?
A: Absolutely. We are an OEM manufacturer. You can provide a 2D/3D drawing, and our engineers will advise on design for manufacturability. We can add slots, ribs, holes, or mounting bosses as needed.
Q6: What packing options are available for export?
A: Standard packing includes anti-static bags, foam cushioning, and corrugated boxes on pallets. For larger quantities, we use export-grade cartons and shrink wrap. Custom packaging (e.g., blister packs, trays) is available upon request.
