Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – a dedicated manufacturer of high-precision injection molds since 2017. We specialize in producing Precision Injection Molds for OEM Plastic Wide-Mouth Jars with Screw Caps, designed to meet the rigorous demands of the packaging industry. Our molds are crafted with an advanced Mold Protection System to ensure long-term stability, reduced downtime, and consistent output quality. Leveraging our TS16969-certified processes and a team of 51-100 skilled employees, we deliver molds that help our clients achieve superior production efficiency and product integrity.
This mold is specifically engineered for producing wide-mouth plastic jars with screw-on caps, commonly used for food, cosmetics, pharmaceuticals, and household products. The design incorporates a robust protection system that monitors and prevents common mold damage such as cavity wear, corrosion, and thermal stress. Below we detail the key features, technical specifications, and the tangible benefits your business will gain from choosing our mold.
Key Features & Technical Specifications
- Precision Engineering: CNC-machined cavities with tolerances within ±0.01mm, ensuring perfect thread alignment and leak-proof sealing between jar and cap.
- Mold Protection System: Integrated sensors and software that detect abnormal pressure, temperature, or ejection force, automatically pausing the cycle to prevent damage and extend mold life.
- High-Quality Materials: Constructed from premium tool steel (P20, H13, or 420SS) with optional surface treatments like nitriding or DLC coating for enhanced wear resistance.
- Multi-Cavity Options: Available in single-cavity, 2-cavity, 4-cavity, or custom configurations to maximize output per cycle.
- Optimized Cooling System: Conformal cooling channels designed via CFD simulation to reduce cycle time by 15-30% and minimize warpage.
- Easy Maintenance: Quick-change insert design for fast cavity swaps and reduced downtime during production changeovers.
- Compliance with Global Standards: Manufactured under TS16969 quality management system, suitable for automotive-grade plastic parts and packaging.
