APEX Machinery proudly presents our PET Wide-Mouth Jar Preform Injection Molding Machine—a specialized injection molding system designed specifically for the efficient production of wide-mouth jar preforms. Wide-mouth containers, including jars for food products, cosmetics, and household items, require preforms with larger neck diameters and unique design characteristics that differ significantly from standard beverage bottle preforms . Our advanced system addresses these specialized requirements while maintaining the high productivity and consistent quality that APEX customers expect.
Wide-mouth jar preforms present unique manufacturing challenges due to their larger neck dimensions and specific material distribution requirements . Our injection molding machine incorporates advanced features to address these challenges:
Optimized for large neck diameters up to 83mm or more, accommodating a wide range of jar applications
Specialized screw and barrel designs configured specifically for PET processing with enhanced plasticizing capacity for larger shot weights
Advanced hot runner systems with individually controlled valve gates ensuring balanced filling across all cavities despite the larger flow paths required for wide-mouth preforms
Precision injection control for consistent material distribution in the critical neck and gate areas
Our wide-mouth jar preform machine is engineered for maximum flexibility to meet diverse market demands:
Multi-cavity configurations ranging from single cavity for very large jars up to multiple cavities for medium-sized wide-mouth containers
Accommodates neck diameters from 30mm to 85mm or more, covering the full spectrum of jar applications from small cosmetic containers to large food jars
Preform weights ranging from 25g to 50g or higher depending on configuration, suitable for containers from 250ml to 1000ml and beyond
Compatibility with both standard PET and rPET materials, supporting up to 100% recycled content with appropriate auxiliary systems
Wide-mouth jar preforms require exceptional precision to ensure proper thread formation and sealing performance . APEX's system incorporates precision components that guarantee quality:
High-performance plasticizing unit with specially designed PET screws featuring optimized L/D ratios for superior melt quality and homogeneity
Advanced valve gate control ensuring consistent filling and preventing defects such as short shots or flow marks
Precision temperature control throughout the hot runner system maintaining ±1°C accuracy to prevent material degradation
Robust clamping unit with sufficient tonnage to maintain mold closure under high injection pressures required for wide-mouth preforms
Efficient cooling is essential for wide-mouth preform production due to the increased material volume in the neck area. Our machine features:
Optimized cooling circuit design with spiral channels ensuring balanced heat extraction across all preform sections
Enhanced neck cooling specifically designed for the thicker cross-sections typical of wide-mouth jar preforms
Post-mold cooling options for applications requiring extended cooling to maintain dimensional stability
Temperature control accuracy within ±1°C ensuring consistent crystallization and preventing warpage
In alignment with global sustainability trends, our wide-mouth jar preform machine incorporates features that reduce energy consumption:
Servo-driven hydraulic systems with accumulators that optimize energy usage during injection cycles
High-efficiency heating elements and insulated barrel designs minimizing thermal losses
Compatibility with recycled PET (rPET) materials, supporting sustainability initiatives and circular economy goals
Reduced specific energy consumption compared to general-purpose machines through optimized machine sizing for wide-mouth applications
Built to withstand the rigors of continuous industrial production, our wide-mouth jar preform machine features:
Clamping forces from 120 to 200 tons or higher depending on configuration, ensuring consistent mold closure for large-neck applications
Generous tie-bar spacing accommodating wide-mouth molds with larger cavity dimensions
High-quality global components from renowned manufacturers ensuring long-term reliability
Durable construction designed for 24/7 operation in demanding production environments
