Whether you need a standard 28mm ribbed cap or a complex multi-start thread design, we deliver with precision and consistency.
Key Features & Technical Specifications
- Custom Ribbed Design: The ribbed outer surface provides enhanced grip for easy opening and closing, even with wet or oily hands. Rib count, depth, and spacing are fully customizable to match your branding or ergonomic requirements.
- Precision Threading: Our molds are engineered with high-tolerance thread inserts to ensure consistent, smooth engagement with bottle necks, preventing cross-threading and leakage.
- Material Flexibility: We work with a wide range of thermoplastics including PP, PE, ABS, PC, and PA, with optional additives for UV resistance, antistatic, or food-grade compliance.
- Strict Quality Assurance: Every production run undergoes 100% visual inspection, dimensional checks using CMM and optical comparators, and leak testing (air pressure or water bath) to guarantee seal integrity.
- IATF 16949 Qualified Process: Our quality system follows the automotive industry’s stringent standards, including APQP, PPAP, FMEA, and SPC, ensuring consistent output and defect prevention.
- Scalable Production: With multi-cavity molds, we can produce from thousands to millions of caps per month while maintaining tight tolerances (±0.05mm typical).

We offer a wide range of thermoplastics including PP, PE, ABS, PC, PET, and PA. For food or pharmaceutical contact, we can use FDA-approved or food-grade materials. Material selection is based on your product’s chemical compatibility, temperature resistance, and mechanical strength requirements. -
What is the minimum order quantity (MOQ)?
For new molds, the MOQ starts at 10,000 pieces. For existing molds (if we have a similar design), MOQ can be as low as 5,000 pieces. We also offer prototype runs for testing with quantities as low as 500 pieces. -
Can you customize the rib pattern and color?
Yes, absolutely. Rib spacing, depth, and count can be tailored to your design. Color matching is available using Pantone, RAL, or your own sample. We can also add a glossy or matte finish, or a dual-color effect if needed. -
How do you ensure the caps are leak-proof?
Our quality assurance includes 100% air pressure leak testing or water bath testing for every batch. We also conduct torque testing to ensure the cap stays securely sealed during transportation and storage. Our IATF 16949 process includes FMEA to identify potential sealing failures. -
What is the typical lead time for a new mold and production?
Mold design and fabrication takes approximately 4–6 weeks, depending on complexity. First article samples are usually available within 1 week after mold completion. Mass production lead time is 2–3 weeks after sample approval. -
Do you provide samples before mass production?
Yes, we provide free samples for evaluation (shipping costs apply). We can also send multiple material/color options for you to test. Once the design is approved, we proceed with production. -
What certifications do you hold?
Our production facility is IATF 16949 qualified, which is a globally recognized standard for automotive quality management. This ensures rigorous process control, traceability, and continuous improvement. We also comply with ISO 9001 principles. -
