Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, brings over seven years of precision mold manufacturing experience to the global market. Our PP/PE Plastic Bottle Cap OEM Injection Molding Service is designed to deliver high-quality, leak-proof caps for a wide range of packaging applications. Leveraging our 1,000–3,000 square meter factory and a skilled team of 51–100 employees, we ensure every mold is crafted with meticulous attention to detail. Our proprietary Mirror Finish S136 Steel Mold technology guarantees exceptional surface quality, reducing friction and extending mold life. With IATF 16949 certification (formerly TS16969), we adhere to rigorous automotive-grade quality standards, making our service a reliable choice for demanding industries. Whether you need caps for beverages, pharmaceuticals, cosmetics, or chemicals, our OEM service offers a comprehensive solution from design to mass production.
Product Features & Technical Specifications
- Materials: We use high-grade PP (Polypropylene) and PE (Polyethylene) that are food-safe, chemically resistant, and recyclable. Custom blends are also available upon request.
- Premium Mold Steel: Our molds are made from S136 stainless steel with mirror finish (SPI A1 grade), which ensures excellent corrosion resistance, high thermal conductivity, and a flawless surface that minimizes sticking and wear.
- Leak-Proof Design: Each cap is engineered with precision sealing geometries, including multi-start threads and inner liners (optional), to ensure zero leakage under pressure and temperature variations.
- Customizability: We offer full customization: cap sizes (18mm to 120mm), colors (Pantone/color matching), logo embossing/debossing, tamper-evident bands, and special features like child-resistant closures.
- High Efficiency: Multi-cavity molds (up to 32 cavities) reduce cycle times and increase output, lowering your per-unit cost.
- Quality Assurance: Every mold undergoes rigorous testing, including dimensional inspection, leak testing, and durability testing. Our IATF 16949 certified processes ensure consistent quality.

Frequently Asked Questions
-
Q: What is the typical lead time for a new bottle cap mold?
A: Lead time depends on complexity. Generally, it takes 20–30 working days for design, mold fabrication, and sampling. We offer express service for urgent orders (15–20 days). -
Q: Can you produce caps with a tamper-evident band?
A: Yes, we specialize in tamper-evident closures. Our molds can integrate band designs, including break-away bands, depending on your bottle neck finish. -
Q: What is the minimum order quantity (MOQ) for cap production?
A: For custom molds, MOQ is typically 100,000 pieces per year. However, we can accommodate smaller pilot runs (10,000–50,000) for prototyping or market testing at a slightly higher unit cost. -
Q: Do you provide color matching and logo printing?
A: Absolutely. We can match any Pantone color using masterbatch. Logo embossing/debossing is included in the mold design. For additional printing (pad printing, hot stamping), we have partners to offer turnkey services. -
Q: How do you ensure the caps are leak-proof?
A: Leak-proof performance is achieved through optimized thread design, precision liner grooves (if needed), and stringent leak testing. We perform pressure and vacuum leak tests on every mold trial. -
Q: What materials can be used besides PP and PE?
A: We also work with PET, HDPE, LDPE, and other thermoplastics. Please discuss your specific material requirements with our technical team; we can recommend suitable options. -
Q: Is the mold fully compatible with standard injection molding machines?
A: Yes, we design mold bases according to standard dimensions (DME, Hasco, or custom). Clamping plates and knockout patterns are customized to fit your machine. -
Q: What after-sales support do you offer?
A: We provide full technical support during mold setup and production. Spare parts (cores, cavity inserts) are available. Our warranty covers 1 year or 1 million shots, whichever comes first, against material or workmanship defects.
