Introduction
At Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017 with a 1,000-3,000 m² factory and a dedicated team of 51-100 professionals, we pride ourselves on delivering high-precision tooling solutions. Our OEM Flip-Top Cap Mold with 16 Cavities, High Gloss Mirror Finish, IATF 16949 & ISO 9001, for PP/PE Material, Precision Hot Runner System represents the pinnacle of efficiency and quality for bottle cap production. This mold is engineered to meet the demanding requirements of the packaging industry, offering exceptional cycle times, consistent part quality, and a mirror-like surface that eliminates secondary polishing. Trust our expertise to give your production line a competitive edge.
Key Features & Technical Specifications
- 16-Cavity Layout: Balanced flow design ensures uniform filling across all cavities, maximizing output per cycle.
- High Gloss Mirror Finish: Cavity surface roughness ≤ Ra 0.05 μm, achieving a flawless glossy cap appearance without additional post-processing.
- Precision Hot Runner System: Individually controlled nozzle tips with multi-zone temperature control, minimizing material waste and reducing cycle time by up to 20%.
- Material Compatibility: Optimized for PP (Polypropylene) and PE (Polyethylene) — the most common cap materials, with options to process other thermoplastics upon request.
- IATF 16949 & ISO 9001 Certified: Our manufacturing processes follow strict automotive-grade quality standards, ensuring repeatable performance and dimensional stability.
- Durable Mold Construction: Premium tool steel (e.g., 1.2343 ESR) with hardened inserts, rated for over 2 million shots before minor maintenance.
- Efficient Cooling System: 3D conformal cooling channels reduce cooling time and minimize warpage, providing fast and uniform heat transfer.
- Interchangeable Inserts: Quick-change cavity inserts allow easy conversion between different cap designs (e.g., flip-top hinge geometry).

Advantages & Customer Benefits
- Increase Output: 16 cavities per cycle mean you can produce hundreds of thousands of caps per day with a single mold, reducing the number of required molds and associated costs.
- Eliminate Post-Processing: The high-gloss mirror finish directly from the mold removes the need for buffing or spraying, saving labor and workshop space.
- Reduce Material Waste: Precision hot runner technology with individual temperature control minimizes scrap due to short shots or flash, especially during startup and color changes.
- Consistent Quality: Excellent cavity-to-cavity balance (±1.5% weight variation) ensures every cap meets tight dimensional and visual standards, critical for brand identity.
- Long Mold Life: Hardened tool steel and optimized heat treatment provide durability even under high-volume production, lowering your long-term tooling investment.
- Quick Changeover: Interchangeable inserts and standardized backplate design allow fast conversion to other cap styles, increasing machine utilization.

Frequently Asked Questions (FAQ)
Q1: Which materials can this mold process?
A: The mold is primarily designed for PP (polypropylene) and PE (polyethylene). However, with suitable hot runner nozzle tips and gate geometry, it can also process other thermoplastics such as PET, PS, or ABS. Please advise your target material during the inquiry so we can adjust accordingly.
Q2: What is the expected mold life?
A: With proper maintenance and using recommended injection parameters, this mold can achieve over 2,000,000 cycles. Critical components like cavity inserts are made of hardened steel and can be replaced individually to extend the overall lifespan.
Q3: How long is the delivery time?
A: Standard delivery for a 16-cavity flip-top cap mold is approximately 40-50 working days after design approval and deposit. Rush orders may be possible at an additional cost. We will provide a detailed schedule upon order confirmation.
Q4: Can I customize the cap design?
A: Absolutely. We offer full OEM customization. You can provide your cap 3D file or sample, and our engineering team will optimize the mold layout including gate location, cooling channels, and ejection system for your specific design.
Q5: Do you provide trial shots before shipment?
A: Yes, we conduct injection trials on our own machines (200-350 ton) for every mold. We send a trial report along with sample caps for your approval before shipping. Video recording of the trial process is also available.
Q6: What hot runner brand do you use?
A: We offer flexible options: standard configuration uses reliable brands like YUDO, Mold-Masters, or HRSflow based on your preference. The system is fully pre-wired, tested, and comes with a temperature controller.
Q7: How do you ensure the mirror finish quality?
A: Our polishing process involves multiple stages from rough grinding to diamond paste finishing, followed by surface roughness measurement with a profilometer. The final cavity is verified against a master sample to guarantee Ra ≤ 0.05 μm.
Q8: What after-sales support do you offer?
A: We provide 12-month warranty on mold workmanship (excluding wear parts). Technical support via email, phone, or video call is available. Spare parts such as ejector pins, nozzles, and inserts can be supplied upon request.
