Changzhou Hongxinyutai Precision Mold Co., Ltd. (Est. 2017) is a specialized manufacturer of high-precision injection molds for the cosmetic packaging industry. Our Precision Thick-Wall Cosmetic Packaging Mold featuring a Hot Runner System is engineered for demanding production environments where consistent quality, long tool life, and flawless surface finish are non-negotiable. Designed with S136 tool steel and mirror-polished cavities, this mold delivers 300,000 reliable shots, making it an ideal solution for manufacturers of luxury cosmetic containers.
This mold is built to produce thick-wall cosmetic packaging components—such as jars, bottles, and caps—with exceptional dimensional accuracy and aesthetic appeal. The integration of a hot runner system eliminates cold runner waste, reduces cycle time, and improves part consistency. Combined with our advanced cooling design, it ensures uniform temperature distribution and minimizes warpage, even for high-volume runs.
Key Features & Technical Specifications
- Premium Material: Mold core and cavity are made from S136 tool steel, known for its excellent corrosion resistance, high hardness, and superior polishability, ensuring a mirror finish that meets SPI A1 standards.
- Mirror Polish Surface: Achieves a surface roughness Ra ≤ 0.01 μm, providing a high-gloss appearance on the molded parts, essential for cosmetic packaging.
- Hot Runner System: Equipped with a precision hot runner (e.g., from leading brands like YUDO, INCOE, or equivalent upon request), enabling gate vestige reduction, faster cycles, and zero waste.
- Durability & Longevity: Rated for 300,000 shots under normal production conditions, with replaceable inserts and wear-resistant design to extend mold life significantly.
- High Precision Machining: Tolerances maintained within ±0.01 mm on critical dimensions, achieved through CNC machining and EDM processes.
- Advanced Cooling System: Conformal cooling channels are optimized via simulation (Moldflow) to reduce cooling time by up to 30%, improving productivity.
- Customizable Design: Mold base, number of cavities (single/multi), gate type, and ejection system can be tailored to your specific part geometry and production volume.
| Parameter | Specification |
| Cavity Material | S136 (1.2083) ESR, hardened to 48-52 HRC |
| Surface Finish (Cavity) | Mirror polish, Ra ≤ 0.01 μm (SPI A1) |
| Hot Runner System | Full hot runner with temperature control, valve gate or open gate (as required) |
| Expected Mold Life | 300,000 shots (under normal maintenance) |
| Precision Tolerance | ± 0.01 mm on critical dimensions |
| Cooling Method | Conformal cooling channels (water or oil) |
| Mold Weight | Variable based on design (typically 500-2000 kg) |
| Compatible Machine | Injection molding machine with appropriate clamp force (e.g., 120-300 ton) |
Advantages for Your Production
- Reduced Scrap: Hot runner eliminates runners, saving material and reducing waste—especially valuable for expensive cosmetic resins.
- Faster Cycle Times: Efficient cooling and balanced fill reduce cycle time by 15-25% compared to conventional molds, increasing output.
- Superior Part Quality: Mirror-polished cavities produce high-gloss, blemish-free surfaces that meet the strictest cosmetic packaging standards.
- Low Maintenance: S136 steel resists corrosion from acidic or pigmented materials, and the hardened surface minimizes wear, reducing downtime.
- Flexibility: Customizable cavity count, gating, and ejection system to match your exact production requirements (small to large series).
- Global Compliance: Our molds are built to international standards and have been successfully shipped to markets across North America, Europe, Asia, and Oceania.

Frequently Asked Questions
Q1: What is the typical lead time for this mold?
A: Standard lead time is 30-45 days from design approval, but we can expedite to 25 days for urgent orders (subject to production schedule).
Q2: Can the hot runner system be sourced from a specific brand like YUDO or Husky?
A: Yes, we can integrate hot runner systems from leading brands as per your preference or our standard high-quality supplier. Please indicate your preferred brand during inquiry.
Q3: How do you guarantee 300,000 shots?
A: The mold is designed with hardened S136 steel and proper maintenance plans. We conduct fatigue analysis and provide recommended upkeep intervals. Actual life may vary depending on material, cycle parameters, and maintenance.
Q4: What surface finish can I expect for the molded parts?
A: The mirror-polished cavity achieves a gloss level equivalent to SPI A1 (Ra ≤ 0.01 μm), producing parts with high clarity and shine suitable for premium cosmetic packaging.
Q5: Can you handle multi-cavity molds for high-volume production?
A: Absolutely. We can design molds with 2, 4, 8, or more cavities depending on your production volume and part size. Multi-cavity molds require careful balancing of the hot runner system, which we address through Moldflow simulation.
Q6: What materials are compatible with this mold?
A: The mold is suitable for a wide range of thermoplastics commonly used in cosmetics: PP, PE, PET, ABS, SAN, PMMA, PETG, and others. For highly corrosive materials, we can recommend additional surface treatments.
