At Changzhou Hongxinyutai Precision Mold Co., Ltd., we take pride in delivering high-quality custom injection molding solutions for the packaging industry. Since our establishment in 2017, we have grown into a reliable manufacturer with a dedicated factory spanning 1,000–3,000 square meters and a skilled team of 51–100 employees. Our custom PP bottle injection mold featuring a 1×16 cavity tooling and a guaranteed 300,000 shots longevity is engineered to meet the rigorous demands of mass production while maintaining exceptional precision and consistency. Backed by our TS16969 certification (a precursor to IATF 16949), this mold is built for automotive-level quality standards, making it an ideal choice for clients who require reliable, high-volume bottle manufacturing.
Our mold is designed specifically for polypropylene (PP) bottles, a material widely used in food, beverage, pharmaceutical, and cosmetic packaging. The 16-cavity configuration significantly increases output per cycle, reducing per-unit cost and improving overall production efficiency. With a mold life of 300,000 shots, this tool offers long-term durability and consistent performance, even under continuous operation. Below you will find a detailed breakdown of the technical specifications and key advantages that set our mold apart.
Technical Specifications
| Parameter | Value |
|---|---|
| Cavity Number | 1×16 (16 cavities) |
| Product Material | Polypropylene (PP) |
| Mold Base Steel | P20, H13, or 718H tool steel (optional) |
| Mold Life | 300,000+ shots |
| Certification | TS16969 |
| Cooling System | Optimized conformal cooling for uniform cooling |
| Gate Type | Customizable (e.g., pin point, submarine, hot runner) |
| Shrinkage Rate | Adjustable per PP grade (typically 1.5%–2.5%) |
Key Features & Benefits
- High Cavity Count Boosts Productivity: The 1×16 cavity design allows you to produce 16 bottles in a single cycle, dramatically increasing output per hour. This is especially advantageous for large-volume orders and reduces your per-unit tooling cost.
- Long Mold Life for Low Maintenance: Built with premium tool steel and precision machining, our mold is guaranteed to withstand 300,000 shots under normal operating conditions. This translates to fewer replacements, less downtime, and a lower total cost of ownership.
- TS16969 Certified Quality System: Our manufacturing process adheres to the strict quality management standards TS16969, ensuring consistent precision, traceability, and defect reduction. This certification is widely recognized in the automotive and high‑precision industries, giving you confidence in every mold we produce.
- Optimized Cooling for Faster Cycle Times: We employ conformal cooling channels designed via CAE analysis to achieve uniform temperature distribution. This minimizes warpage and sink marks while reducing cycle times by up to 15%–20% compared to conventional cooling designs.
- Fully Customizable Design: Every aspect of this mold can be tailored to your specific bottle design — from neck finish and thread configuration to body shape, wall thickness, and surface texture. We also support hot runner systems, cold runner layouts, and special gating options.
- Comprehensive After-Sales Support: Our experienced engineering team provides technical guidance throughout the mold life, including troubleshooting, maintenance recommendations, and spare parts supply. We also offer mold trial services at our facility before shipment.

Frequently Asked Questions
-
Q: What is the typical lead time for this 16-cavity PP bottle mold?
A: Standard lead time is approximately 25–35 working days after design approval. Rush orders can be accommodated with a priority fee. -
Q: Can the mold accommodate different bottle sizes or shapes?
A: Yes, we offer full customization. You provide drawings or samples, and our engineers will design the cavity accordingly. The 1×16 layout can be adapted to various bottle geometries within the mold base size limits. -
Q: What warranty do you offer on the mold?
A: We provide a 12-month warranty on materials and workmanship against defects under normal use. Extended warranty plans are available upon request. -
Q: Do you provide mold trial services?
A: Yes, we can perform trial runs at our factory using your specified PP resin. We will record parameters and provide a trial report to ensure the mold meets your quality standards. -
Q: Is the mold compatible with standard injection molding machines?
A: Absolutely. We design the mold to fit common machine specifications (e.g., clamping force, mold height, ejection system). We will confirm dimensions with your machine details before manufacturing. -
Q: What grades of polypropylene are recommended?
A: The mold works with most commercial PP grades, including homopolymer, copolymer, and impact-modified. We can adjust gate and cooling design based on the specific PP grade's flow and shrinkage characteristics. -
Q: How do you ensure the 300,000-shot longevity?
A: We use high-hardness tool steel (e.g., H13, 718H) with proper heat treatment, plus wear-resistant coatings on critical surfaces. Regular maintenance, such as cleaning cooling channels and applying anti-rust treatment, also extends mold life. -
Q: Do you provide spare parts or replacement cavities?
A: Yes, we can supply spare cavities, cores, and wear parts to maintain production continuity. We also offer mold refurbishment services at competitive rates.
