Applications of Wide-Mouth PET Preform Molds

• Food Packaging: Jars for sauces, spreads, nuts, and snacks (40mm+ neck diameters).

• Cosmetics & Personal Care: Creams, lotions, and balms with smooth, wide-access designs.

• Household Products: Detergents, cleaning agents, and bulk storage containers.

• Industrial Packaging: Chemical-resistant wide-neck containers for safe handling.

Key Features of LEIZHEN’s Wide-Mouth Mold Designs

1. Reinforced Thread & Seal Systems

   • Robust thread designs for secure closures, preventing leaks in viscous products.

   • Optimized sealing surfaces compatible with induction liners or tamper-evident caps.

2. Uniform Wall Thickness Distribution

   • Advanced mold flow simulation ensures even material distribution, reducing warpage and enhancing jar stability.

3. Enhanced Cooling Channel Layout

   • Strategically designed cooling systems minimize cycle times for thick-walled jars.

4. Multi-Cavity Configurations

   • Molds with 4 to 96 cavities for high-volume production, tailored to jar sizes (100ml to 5L+).

Technical Advantages in Wide-Mouth Mold Manufacturing

• Material Expertise: Use of hardened steel (H13, Stainless Steel 420) and coatings (chrome, nitriding) for wear resistance and extended lifespan.

• Precision CNC Machining: 5-axis CNC technology achieves micron-level accuracy (±0.02mm) for seamless cap compatibility.

• Hot Runner Systems: Integrated hot runners reduce material waste and ensure consistent fill rates for wide necks.

SEO Focus: High-precision wide-neck molds, CNC-machined jar preform molds.

Customization Options

• Neck Diameters: Standard sizes (38mm, 40mm, 45mm, 48mm) or fully custom specifications.

• Thread Profiles: ISO, PCO, or bespoke threading for unique cap requirements.

• Surface Finishes: Glossy, matte, or textured finishes for brand-specific aesthetics.

Quality Assurance & Compliance

• Rigorous Testing: Cycle testing (500,000+ cycles) and CMM inspections for dimensional accuracy.

• Certifications: Compliant with FDA, EU, and ISO standards for food safety and recyclability.

• Durability Guarantee: Molds withstand high-viscosity materials (e.g., peanut butter, hair masks) without degradation.
