Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – a professional manufacturer established in 2017, with a factory spanning 1,000–3,000 square meters and a dedicated team of 51–100 employees. We specialize in precision injection molds and are proud to introduce our High-volume food cap tooling, designed for mass production of plastic food caps. This mold features 1x24 cavities, a hot runner system, premium S136 steel construction, a glossy finish, a lifespan of 300,000 cycles, and full compatibility with robotic arms. It is the ideal solution for food packaging manufacturers seeking consistent output, minimal downtime, and superior part quality.
Our mold is engineered to meet the demanding requirements of high-volume production lines. The combination of 24 cavities and a hot runner system allows for faster cycle times, reduced scrap, and lower per-part cost. The S136 steel provides excellent corrosion resistance and wear performance, while the glossy finish ensures that food caps have a smooth, aesthetically pleasing surface. With a verified lifespan of 300,000 cycles, this tooling delivers reliable long-term performance. Moreover, the mold is fully compatible with standard robotic arms, enabling automated part removal and further boosting production efficiency.
Key Features and Advantages
- 24-Cavity Design: Maximizes output per cycle – ideal for high-volume food cap production, significantly increasing efficiency and reducing unit cost.
- Hot Runner System: Eliminates cold runner waste, reduces cycle time, and provides precise temperature control for consistent filling and minimal gate vestige.
- S136 Steel Construction: This high-grade stainless steel offers exceptional hardness, corrosion resistance, and polishability, ensuring a long service life and excellent part surface finish.
- Glossy Finish: The mirror-like surface quality meets stringent aesthetic requirements for food caps, improving market appeal and product differentiation.
- 300,000-Cycle Lifespan: Rigorously tested to maintain dimensional stability and performance over an extended production run, reducing the need for frequent mold replacement.
- Robotic Arm Compatible: Designed with standard mounting and ejection interfaces for seamless integration with pick-and-place robots, enabling fully automated operation.
- Customizable Options: Available upon request – modifications to cavity shape, gate type, cooling layout, and texture can be made to suit specific cap designs.

Benefits for Your Production: By implementing this high-volume food cap tooling, you can achieve a cycle time reduction of up to 30% compared to conventional cold runner molds. The hot runner system minimizes material waste, while the 24 cavities allow you to produce 15%–25% more caps per hour than a 16-cavity design. The S136 steel ensures that the mold remains free of corrosion and wear even when processing corrosive resins (e.g., food-grade PP or PE containing additives). Additionally, the glossy finish eliminates the need for secondary polishing in most applications, reducing post-mold finishing costs.

Frequently Asked Questions
-
Q: What materials can be processed with this mold?
A: This mold is designed primarily for food-grade polypropylene (PP) and polyethylene (PE), but it can also process other thermoplastics such as polystyrene (PS) or ABS. Please inform us of your resin type so we can adjust the cooling and gate design accordingly. -
Q: Is the hot runner system brand specified?
A: We can supply standard hot runner components from reliable brands (e.g., Yudo, Synventive, or Haseco) according to your preference. The default is a proven system that balances cavity filling evenly. -
Q: Can the mold be modified for a different cap diameter?
A: Yes, we offer customization. The cavity dimensions, core and cavity inserts can be machined to accommodate different cap sizes (typical range: 20mm–50mm diameter). Please provide your cap drawing for evaluation. -
Q: What is the delivery time?
A: For a standard 24-cavity food cap mold, the typical lead time is 35–45 days after design approval and deposit. Rush orders can be negotiated for an additional fee. -
Q: Does the mold come with a warranty?
A: Yes, we provide a 12-month warranty against manufacturing defects under normal operating conditions. Maintenance training and spare parts are available. -
Q: How do you ensure the mold works with our robot?
A: We design the mold base with standard clamping slots and ejector mounting patterns that are compatible with most robotic arm grippers. We can also customize the ejector plate and knockout pattern to match your robot’s pick-up system. -
Q: What is the recommended injection machine size?
A: We recommend an injection machine with clamping force of 150–250 tons, depending on the projected area of the caps. Specific calculations will be provided in the mold design proposal. -
Q: Can we get samples before full production?
A: Absolutely. After mold fabrication, we perform trial shots and can ship you sample caps for approval before mass production. We also provide a mold test report with cycle times and quality data.
