Frequently Asked Questions
- What materials can you use for ribbed screw caps? We commonly use PP, PE, ABS, and other thermoplastics. For food contact applications, we can provide FDA or EU-compliant options upon request.
- How long does it take to develop a custom mold? Typical mold fabrication takes 20–30 working days, depending on complexity. We can also use existing molds for standard sizes to shorten lead time.
- What is the minimum order quantity for mass production? There is no strict MOQ; we can start with a few thousand pieces for pilot runs and scale up to millions. Contact us for a quote based on your volume.
- Do you offer sample testing before mass production? Yes, we provide samples from the first-shot mold trial for dimensional and functional testing. Samples can be shipped within 7–10 days after mold completion.
- How do you ensure the caps are leak-proof? We perform 100% leak testing using pressurized air or water immersion on a sampling basis, and we can implement full inspection if required.
- Can you add my company logo or text on the cap? Yes, we can engrave logos, text, or patterns on the mold cavity for permanent markings. This is best discussed during the design phase.
- What is the typical lead time for high-volume orders? For mass production (e.g., 500,000+ pieces), lead time is 15–25 working days after mold approval. We maintain buffer capacity to handle urgent orders.
- Do you support international shipping? Absolutely. We ship from Jiangsu, Shanghai, or Shenzhen ports via sea, air, or express. Our logistics team handles customs documentation for smooth delivery.
