At Changzhou Hongxinyutai Precision Mold Co., Ltd., we specialize in designing and manufacturing high-performance blow molds for PP bottles. Our High Output PP Bottle Blow Mold is engineered for maximum efficiency and durability — featuring multi-cavity configurations, hardened steel construction, and automatic part removal to meet the demanding production requirements of modern bottling lines. With a proven lifespan of 300,000 shots, this mold delivers consistent quality and reduces downtime, ensuring a strong return on investment for producers worldwide.
Whether you are packaging beverages, personal care products, or household chemicals, our blow mold provides tight tolerances, excellent surface finish, and rapid cycle times. Backed by our TS16969-certified manufacturing process, every mold undergoes rigorous quality checks to guarantee performance and reliability.
Key Features & Benefits
- Multi-Cavity Design — Increases output per cycle, reducing unit cost. Choose from 4, 6, 8, or more cavities based on your production volume.
- Hardened Steel Construction — Utilizes premium tool steel (e.g., P20, H13, 718H) with heat treatment to resist wear and thermal fatigue, extending mold life beyond 300,000 shots.
- Automatic Part Removal — Integrated ejector system and air-assist technology allow finished bottles to be released without manual intervention, improving safety and cycle time.
- Optimized Cooling System — Conformal cooling channels ensure uniform temperature distribution, reducing warpage and cycle time by up to 15%.
- High Surface Finish — Mirror-polished cavities (Ra ≤ 0.2 μm) produce bright, defect-free bottle surfaces suitable for labeling and decoration.
- Low Maintenance — Replaceable wear plates and hardened inserts simplify repairs and prolong overall tool life.
- Customizable Neck Finishes — Compatible with standard and custom neck finishes (e.g., PCO 1810, 38mm, 28mm) to meet closure requirements.

Frequently Asked Questions
-
Q: What bottle shapes and sizes can this mold produce?
A: Our mold can accommodate a wide range of cylindrical, oval, and custom shapes from 50 ml to 5 L. We work from your 3D design or sample to ensure precise replication. -
Q: Is the cavity count fixed or customizable?
A: The cavity count is fully customizable based on your production volume. Typical options include 2, 4, 6, 8, 10, and 12 cavities. We will recommend the optimal configuration after reviewing your machine tonnage and cycle time targets. -
Q: What materials are used for the mold base and cavities?
A: We use high-quality hardened tool steels such as P20, H13, and 718H. Cavities are heat-treated to 48–52 HRC for maximum wear resistance. Inserts and cores are made from S136 or 420 stainless steel for superior corrosion resistance. -
Q: How is automatic part removal achieved?
A: The mold integrates mechanical ejector pins and compressed air nozzles that release the finished bottle from the cavity. A sensor detects part presence and triggers the removal sequence, ensuring reliable operation without manual intervention. -
Q: What is the typical lead time for a custom mold?
A: Lead time depends on complexity and current workload. Standard multi-cavity molds are typically delivered within 30–45 working days. We offer expedited options upon request. -
Q: Do you provide mold testing before shipment?
A: Yes, we offer mold trial services at our facility or your designated machine. We can adjust parameters to achieve optimal bottle weight, wall thickness, and surface quality before dispatch. -
Q: Is the mold compatible with my existing blow molding machine?
A> We design the mold base and mounting dimensions to match your machine model. Please provide the machine brand, model, and platen mounting pattern when placing an order. -
Q: What after-sales support do you provide?
A: We offer technical support via video calls, on-site assistance for critical launches, and a warranty against manufacturing defects. Spare parts are available for quick replacement.
