As a leading manufacturer based in Changzhou, Jiangsu, China, Changzhou Hongxinyutai Precision Mold Co., Ltd. has been dedicated to delivering high-quality injection molds since 2017. Our Multi-Cavity Plastic Pet Bowl Injection Molding Tool is engineered to meet the demanding needs of pet product manufacturers worldwide. This tool combines P20/718 hardened steel with an optimized water cooling channel and high-efficiency robotic arm collection, ensuring superior durability, rapid cycle times, and fully automated production. Whether you produce small or large pet bowls, this multi-cavity design maximizes output while maintaining precision and consistency—backed by our TS16969-certified quality management system.
Product Features & Technical Specifications
- Material Excellence: Constructed from premium P20/718 pre-hardened steel, offering exceptional wear resistance, toughness, and polishability. The hardened state (approx. 48-52 HRC) ensures long mold life even under high-volume production.
- Multi-Cavity Design: Available in 2, 4, 6, 8 cavities (customizable), allowing simultaneous molding of multiple pet bowls per cycle—drastically improving productivity and reducing per-unit cost.
- Optimized Water Cooling Channel: Strategically placed conformal cooling channels ensure uniform temperature distribution across the mold. This minimizes warpage, reduces cooling time by up to 30%, and accelerates cycle times.
- High-Efficiency Robotic Arm Collection: Integrated with a robotic arm system that automatically picks finished parts, gates, and runners. This eliminates manual intervention, enhances safety, and supports 24/7 unmanned operation.
- Precision & Consistency: CNC-machined cavities with tight tolerances (±0.02 mm) guarantee identical dimensions and surface finish for every pet bowl, batch after batch.
- Hot Runner / Cold Runner Options: Designed to accept both hot runner systems (for faster cycles) and cold runner systems (for lower tooling cost), depending on customer preference.
- Easy Maintenance: Modular construction with replaceable inserts and wear parts. Standard MUD quick-change frame compatibility available.

Why Choose Our Pet Bowl Mold?
Designed specifically for high-volume pet bowl production, this mold offers tangible benefits for plastic manufacturers:
- Higher Output: Multi-cavity configuration lets you produce 2-8 bowls per cycle, increasing hourly production by 200-800% compared to single-cavity molds.
- Lower Energy Costs: Faster cycle times reduce machine operating hours per part, cutting electricity consumption by up to 20%.
- Superior Part Quality: Uniform cooling eliminates sink marks and warpage, ensuring bowls with excellent dimensional stability and a smooth finish that pet owners appreciate.
- Automation Ready: Robotic arm collection integrates seamlessly with existing injection molding machines (e.g., Haitian, Demag, Engel) and can be synchronized for optimal efficiency.
- Reduced Scrap Rate: Precision machining and balanced cooling reduce defects to less than 0.5%, saving material and rework costs.
- Customization Flexibility: We can adjust cavity number, part shape (round, oval, divided), and surface texture (matt, glossy, non-slip) per your requirements.

Frequently Asked Questions
Q1: What materials can be used with this mold?
A: This mold is compatible with a wide range of thermoplastics including PP, PE, ABS, PET, and nylon. For high-temperature materials like polycarbonate, we recommend a hardened steel upgrade to 718H or H13. Please consult our engineers for material-specific recommendations.
Q2: Can the cavity count be customized for small batch production?
A: Yes, we offer 2-cavity designs for low-volume production, as well as 4, 6, or 8 cavities for high-volume runs. The mold base is designed to allow future cavity increases via interchangeable inserts, providing scalability.
Q3: How does the robotic arm collection system work?
A: A 6-axis robot (optional) or dedicated picker arm automatically removes the finished bowls and runners from the mold after ejection. It places them on a conveyor or into packaging, synchronizing with the molding cycle. The system requires a PLC connection to your injection molding machine.
Q4: What is the typical lead time for this mold?
A: Standard lead time for a multi-cavity pet bowl mold is 30-45 business days after design approval. Expedited delivery (20-25 days) is available for an additional fee. We recommend placing orders 2-3 months before your target launch date.
Q5: Do you provide mold trial and sample parts?
A: Yes, we perform a mold trial at our factory before shipment, running at least 200 cycles to validate function and part quality. We can provide up to 50 sample parts (bowls) for your evaluation. Video recording of the trial is also available.
Q6: What is the warranty period for this mold?
A: We offer a 12-month warranty from the date of shipment covering manufacturing defects in material and workmanship. Wearing parts such as ejector pins and sliders are covered for 6 months. Extended warranty plans are available upon request.
Q7: How do you handle after-sales support?
A: Our dedicated after-sales team provides remote troubleshooting via video call, and we can dispatch engineers to your site within 48 hours for critical issues. Spare parts are kept in stock and can be shipped worldwide within 5 working days.
Q8: Can I visit your factory before ordering?
A: Absolutely. We welcome factory visits in Changzhou, Jiangsu, China. Please schedule an appointment with our sales team, and we'll arrange a comprehensive tour of our design, machining, assembly, and testing departments.
