At Changzhou Hongxinyutai Precision Mold Co., Ltd., we specialize in delivering high-performance injection molds tailored to the pet product industry. Our High-Cavity Pet Bowl Mold is engineered to produce food-grade PP bowls with exceptional efficiency and consistency. Crafted from premium S136 and H13 steel, this mold offers a remarkable 1,500,000-shot lifespan, ensuring long-term reliability for mass production. With a cold runner design and robotic pickup system, our mold minimizes waste and maximizes automation, making it an ideal solution for manufacturers seeking high output and cost-effectiveness.
This mold is specifically designed for high-volume pet bowl production, featuring multiple cavities that significantly increase productivity without compromising part quality. The use of food-grade PP ensures that the final products are safe for pets, complying with rigorous safety standards. Our advanced manufacturing capabilities, backed by TS16969 certification (automotive quality management system), guarantee precision and repeatability across every shot.
Key Features & Technical Specifications
- Superior Steel Combination: The mold core and cavity are made of S136 (stainless) and H13 (hot work) steel, providing excellent corrosion resistance and thermal fatigue resistance.
- Extended Mold Life: Rated for 1,500,000 shots under normal operating conditions, reducing downtime and replacement costs.
- Cold Runner System: Eliminates the need for hot runner controllers, simplifying maintenance and reducing initial investment. It also minimizes material waste by using a balanced runner design.
- Robotic Pickup Integration: Designed to work seamlessly with robotic arms for automatic part removal, enhancing production speed and worker safety.
- Food-Grade PP Compatibility: Mold surface is polished to a high gloss (SPI A2 or better) to ensure easy release and smooth finish on PP parts.
- High-Cavity Configuration: Available in 2, 4, 6, 8 or more cavities based on customer requirements, with each cavity producing identical bowls.
- Precision Cooling System: Optimized water channels ensure uniform cooling, reducing cycle time and warpage.
- Quick Mold Change Ready: Standardized clamping and ejection system for fast changeover.

Our mold is designed with a balanced cold runner system that ensures equal filling of each cavity, resulting in consistent part dimensions and minimal flash. The robotic pickup feature not only speeds up cycle time but also reduces the risk of part damage during ejection. Combined with the food-grade PP material, the final bowls are lightweight, durable, and safe for daily use by pets.
Advantages for Your Production
- Lower per-part cost: High cavity count directly reduces unit cost, especially for large volume orders.
- Reduced waste: Cold runner scrap can be reground and reused, improving material utilization.
- Automation ready: Robotic pickup interfaces with standard controllers, easily integrating into existing production lines.
- Fast delivery: Lead time typically 30–45 days depending on cavity complexity; sample approval before mass production.
- Global shipping: We export via ports in Jiangsu, Shanghai, and Shenzhen to markets worldwide.

Frequently Asked Questions (FAQ)
-
Q: Can the mold handle other materials besides PP?
A: While optimized for food-grade PP, the mold can be adapted for other thermoplastics like ABS, PE, or TPR with adjustments to cooling and surface finish. Please consult our engineers for compatibility. -
Q: What is the typical cycle time for a 6-cavity mold?
A: Cycle time depends on part thickness and cooling efficiency, typically ranging from 15 to 25 seconds for pet bowls. Our optimized cooling system helps achieve faster cycles. -
Q: Do you provide samples before mass production?
A: Yes, we offer sample testing (T0/T1) to validate the mold performance and part quality. Samples can be shipped for your approval. -
Q: What is the warranty period for the mold?
A: We provide a standard 1-year warranty against manufacturing defects, covering steel, runner system, and core components. Extended warranty options are available upon request. -
Q: Can the robotic pickup be customized for different robot brands?
A: Absolutely. We design the pickup interface to match your specific robotic arm (e.g., ABB, Fanuc, KUKA). Please provide robot specifications during ordering. -
Q: How do you ensure the mold life reaches 1.5 million shots?
A: We use high-quality S136 and H13 steel with proper heat treatment, plus precision manufacturing and regular maintenance recommendations. Proper use and periodic servicing will help achieve the rated lifespan. -
Q: What is the minimum order quantity (MOQ)?
A: The mold itself is a one-off product, so MOQ is 1 set. However, we often recommend ordering spare parts (e.g., extra cores) for high-volume production to minimize downtime. -
Q: Can you engrave logos or textures on the bowl surface?
A: Yes, we can add custom textures, logos, or patterns on the mold cavity via EDM or engraving, depending on your design.
