As a professional manufacturer of precision injection molds, Changzhou Hongxinyutai Precision Mold Co., Ltd. (established in 2017) is proud to introduce our OEM Food Cap Injection Mold featuring a 1*24 cavity configuration, hot runner system, and premium S136 steel construction. With a factory spanning 1,000–3,000 square meters and a dedicated team of 51–100 skilled employees, we have successfully delivered molds to markets across North America, South America, Europe, Asia, Africa, and Oceania. This mold is engineered to produce high-quality food caps with exceptional dimensional consistency and rapid cycle times, meeting the rigorous demands of the food packaging industry. Backed by TS16969 certification, our manufacturing processes ensure reliability and repeatability.
The 1*24 cavity hot runner mold is designed for mass production of food caps, offering a remarkable balance between output volume and part quality. The hot runner system eliminates the need for cold runners, reducing material waste and minimizing cycle time. Combined with S136 stainless steel – known for its excellent corrosion resistance, high hardness, and superior polishability – this mold delivers long service life and maintains the hygienic standards required for food contact applications. Below is a detailed technical overview:
| Parameter | Specification |
| Cavity Count | 1 x 24 cavities |
| Mold Steel | S136 (equivalent to AISI 420 stainless steel) |
| Hot Runner System | Multi-point valve gated / open nozzle (customizable) |
| Cooling System | Conformal cooling channels for uniform temperature |
| Mold Base | Standard LKM / HASCO / DME (or customized) |
| Injection Capacity | Suitable for 160–300 ton injection molding machine |
| Expected Cycle Time | 8–12 seconds (depending on part design and material) |
| Mold Life Expectancy | Over 1,000,000 shots (with proper maintenance) |
| Application | Food caps (e.g., water bottle caps, condiment caps) |
Key Features and Benefits:
- High Cavity Efficiency: 24 cavities per cycle dramatically increase output per hour, reducing unit cost and accelerating time-to-market for bulk production.
- Hot Runner Advantages: Zero waste from cold runners, lower injection pressure, improved part quality, and faster cycle times compared to conventional cold runner molds.
- S136 Steel Excellence: The mold core and cavity are made from S136 stainless steel, which offers excellent corrosion resistance (ideal for food-grade environments), high wear resistance, and a mirror-like polish finish that ensures easy release and clean appearance of caps.
- Precision Engineering: Each cavity is machined with tight tolerances (±0.02mm) to guarantee dimensional consistency across all caps, critical for sealing performance and ease of capping.
- Robust Cooling Design: Optimized conformal cooling channels reduce hot spots and minimize warpage, leading to stable production and reduced scrap rate.
- Customizable Options: The mold can be tailored to your specific food cap design – logo engraving, cap internal thread geometry, and injection gate location are all flexible.

Frequently Asked Questions (FAQs)
-
Q: What is the typical mold life for this 24-cavity hot runner mold?
A: With proper maintenance, the mold can produce well over 1,000,000 shots. The S136 steel provides excellent hardness and corrosion resistance, ensuring long-term durability. Actual life depends on the material used, maintenance schedule, and operating conditions. -
Q: Can you customize the mold for a specific cap design?
A: Yes, we offer full OEM customization. You can provide your cap 3D model or sample, and our engineers will adapt the cavity geometry, gate location, cooling layout, and ejection system to match your requirements. Logo engraving and thread design are also customizable. -
Q: Is the S136 steel food-safe?
A: S136 is a high-grade stainless steel that meets food contact safety standards (e.g., FDA, EU regulations). It is resistant to corrosion and easy to clean, making it ideal for food cap molding. We recommend using food-grade resins (PP, PE, etc.) to complete the safety chain. -
Q: What injection machine tonnage is required for this mold?
A: The mold is typically designed for machines of 160 to 300 tons injection capacity. However, the exact specification can be adjusted based on your existing machine’s platen size, clamping force, and injection unit. We provide a detailed mold drawing and technical data sheet for compatibility verification. -
Q: How long does it take to deliver the mold?
A: Standard lead time is 30–45 days after design approval and down payment. Urgent orders may be possible depending on current production load – please inquire for a specific quotation. -
Q: Do you offer after-sales support or training?
A: Yes, we provide a one-year warranty covering material defects and workmanship. We also offer free remote troubleshooting via video call, and our technicians can visit your site (subject to arrangement) for initial mold commissioning. Operation manuals are included. -
Q: Can the mold run with all types of plastic for food caps?
A: The mold is optimized for common food cap materials such as polypropylene (PP), high-density polyethylene (HDPE), and low-density polyethylene (LDPE). For other materials like PET or PS, we may need to adjust the cooling and gate design to ensure proper fill and cooling. Please provide the intended resin before order. -
Q: What is the minimum order quantity (MOQ) for this mold?
A: As it is a customized product, the MOQ is 1 mold. However, we recommend ordering at least one set of spare parts (e.g., heater, thermocouple, ejector pins) to minimize future downtime. We can also produce multiple identical molds for high-volume production lines.
