Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your reliable partner in precision tooling since 2017. We specialize in delivering high-performance injection molding services, and our Automatic Injection Molding Service for Bottle Caps exemplifies our commitment to quality and efficiency. With a 24-cavity hot runner mold crafted from hardened S136 (1.2083) steel and integrated mold protection systems, we offer a complete solution that maximizes output while minimizing downtime. Whether you need large-scale production or prototype runs, our facility in Changzhou, Jiangsu (1,000-3,000 sqm) and skilled team of 51-100 professionals stand ready to serve markets across North America, Europe, Southeast Asia, and beyond.
Key Features & Technical Specifications
- 24-Cavity Hot Runner Design – Achieve high output with consistent melt flow. Each cavity is balanced to ensure uniform filling, reducing cycle time by up to 20% compared to cold runner systems.
- Hardened S136 / 1.2083 Steel – Premium mold material with high corrosion resistance and hardness (48-52 HRC). Ideal for high-volume bottle cap production, offering exceptional wear resistance and longer tool life.
- Integrated Mold Protection System – Sensors and monitoring units automatically detect obstructions, low pressure, or abnormal conditions, preventing damage to cavities and cores. This reduces maintenance costs and unplanned stoppages.
- Automatic Operation – Fully automated injection molding process suitable for high-speed production lines. Our molds are compatible with standard injection molding machines (specifications customizable).
- Precision Cooling Channels – Optimized cooling circuit ensures fast and uniform heat dissipation, improving part quality (minimizing warpage, sink marks) and shortening cycle time.
- Customizable Gating & Venting – Hot runner nozzles can be tailored to your cap design (side gate, pin point, etc.), and venting grooves are precision machined to avoid gas traps.

Why Choose Our Bottle Cap Injection Molding Service?
- High Output Efficiency – 24 cavities mean you can produce thousands of caps per hour. Hot runner eliminates sprue waste, improving material utilization.
- Superior Part Quality – Hardened S136 steel ensures smooth cavity surface with minimal friction, resulting in glossy, defect-free caps. Consistent dimensional accuracy (±0.05mm) meets tight tolerances.
- Reduced Downtime – The mold protection system alerts operators instantly if any issue arises (e.g., foreign object, low pressure), preventing damage and maintaining production continuity.
- Cost-Effective for High Volumes – Our tooling amortization is optimized for large runs. Lower per-part cost compared to multi-cavity hot runner molds with inferior steel.
- Global Shipping & Support – We ship from Jiangsu, Shanghai, or Shenzhen ports. Our team provides after-sales technical support, including mold repairs and hot runner maintenance.
Client Benefit in Action: For a beverage company requiring 5 million caps per month, our 24-cavity system runs on a single injection machine, producing 1,200 shots per hour (assuming 7.5 sec cycle). That’s 28,800 caps per hour – meeting demand with just two shifts. The mold protection system reduces emergency stops by 80%, as proven in our internal testing.

Frequently Asked Questions (FAQ)
- What types of bottle caps can be produced with this mold? – Our 24-cavity hot runner mold can produce a wide variety of caps: screw caps, snap-on caps, dispensing caps, and tamper-evident caps, in sizes ranging from 18mm to 38mm diameter. We can adjust cavity design per your sample or drawing.
- How long does it take to manufacture the mold and start production? – Typical lead time is 30–45 working days after design approval. We can expedite to 25 days for urgent orders (surcharge may apply). Shipping time from Chinese ports is 7–15 days depending on destination.
- Is the hot runner system from a specific brand? Can I choose my preferred supplier? – We normally partner with established hot runner brands like Yudo, Mold-Masters, or Husky (optional). You may specify your preferred brand, and we will integrate it. Standard configuration uses a reliable Yudo multi-drop manifold.
- How do you ensure mold protection works effectively? – The system includes: low-pressure switch, cavity pressure sensors, and temperature monitoring. If injection pressure drops below threshold or mold temperature exceeds limit, the machine stops automatically. We also add a mechanical bumper for safety.
- What injection molding machine clamp force is required? – We recommend a machine with 200–350 tons clamping force. The mold base is designed to fit standard platen sizes. Please provide your machine specifications for precise matching.
- Can you handle multi-color or multi-material caps? – Currently our standard service is single-material injection molding (single color). However, we can design in-mold assembly or over-molding features upon request. Please discuss with our engineers.
- What after-sales support do you provide? – We offer one-year warranty on mold components (excluding wear parts). Spare parts (heater bands, thermocouples, nozzles) are available from stock. Remote troubleshooting via video call is free; on-site service can be arranged at cost.
- How do you handle mold testing and sample approval? – We run a full trial using your specified resin (PP, HDPE, PE, etc.) and produce 200 samples. Dimensional reports, photos, and videos are sent for approval before shipping. You can also visit our Changzhou factory for witnessing trials.
