II. Standard Production Process of Jeepine Bottle Cap Full Production Line
1. Cap Compression System – Core Procedure of Bottle Cap Forming
Regarded as the "heart" of the whole production line, the Jeepine Cap Compression Machine adopts advanced compression molding technology to replace traditional injection molding for bottle cap forming. Raw materials are processed with precise temperature control and high-pressure mold compression in a closed system to complete one-time integral forming of bottle caps.
Core Advantages: Fast forming speed and high dimensional accuracy. It effectively avoids common problems of injection molding such as flash marks, sink marks and uneven internal stress, and provides a stable precision foundation for subsequent key structures like threads and sealing rings.
Application Scenarios: Suitable for plastic bottle cap molding in food & beverage, daily chemical, pharmaceutical and other industries, and supports quick replacement of molds for different cap types and specifications.
2. Cooler System – Rapid Shaping to Ensure Dimensional Stability
Newly compression-molded bottle caps are at high temperature. If directly sent to the next process, they are prone to deformation and warpage caused by thermal expansion and cold contraction. The cooler system adopts precise temperature control and cooling technology to enable fast shaping of caps through uniform cooling. It ensures stable dimensional tolerance of key parts such as threads and tamper-evident rings, and avoids material jamming and processing deviation in subsequent processes.
Optional Configuration: Independent and centralized cooling supply systems are available, which can be flexibly selected according to production line scale and workshop layout.
3. Sorting System – Posture Correction Hub for Automated Production
Cooled bottle caps are in a disorderly state. The sorting system adopts directional conveying and posture correction technology to make all bottle caps move forward in a unified direction for the next process. As a key connecting link of automated production, it effectively prevents equipment jamming and processing failure caused by incorrect cap posture, and guarantees continuous and stable operation of the whole production line.
4. SFS Slitting & Folding System – Key to Tamper-Evident Structure Forming
This is the core process for forming the tamper-evident ring of bottle caps, which directly determines the anti-tampering performance of caps and meets the mandatory safety requirements of the food & beverage industry. The system uses high-precision cutting tools to complete accurate ring slitting, and shapes the edge of the tamper-evident ring through the edge folding mechanism to form the standard anti-opening structure familiar to consumers.
5. Printing System – Brand Logo and Appearance Presentation
After basic forming, bottle caps will be printed with brand LOGO, production date, patterns and other information. The Jeepine full production line supports multiple printing processes to meet customers' diverse appearance needs:
Offset Printing System: Suitable for mass production with simple patterns, low cost and high efficiency.
Digital Printing System: Supports personalized and small-batch custom patterns with no plate making required, featuring high flexibility.
Mixed Printing System: Takes into account mass standardized production and small-batch customized demands, adapting to diversified market scenarios.
All printing processes adopt ink that meets food-contact material safety standards, ensuring clear printing effect, strong adhesion and no precipitation of harmful substances.
6. Secondary Sorting System – Posture Re-Correction After Printing
Bottle caps may have posture deviation during conveying after printing. The secondary sorting system corrects the cap posture again to ensure all caps enter the inspection link with unified posture, laying a solid foundation for high-precision visual inspection.
7. Laser Coding System – Permanent Marking for Product Traceability
To meet the demand of full-link product traceability, bottle caps need to be marked with batch number, traceability code, validity period and other information. The laser coding system adopts non-contact etching technology to permanently mark information on the cap surface, with the features of friction resistance, falling-off resistance and high definition. It fully meets the traceability and supervision requirements of food, beverage and pharmaceutical industries.
8. Online Inspection System – Full Inspection to Reject Defective Products
It is the final quality inspection link before bottle caps leave the factory and the key to ensuring product consistency. With visual inspection technology, the system conducts all-round quality detection on bottle caps and automatically removes unqualified products.
Basic Inspection Items: Dimensional deviation, thread defects, damaged tamper-evident rings, blurred printing, surface stains and impurities, etc.
Optional Configuration: Optional single-lens, dual-lens, seven-lens and multi-lens visual inspection systems, which can be selected according to cap complexity and quality standards. The multi-lens system realizes 360° dead-angle-free detection and covers more potential defects.
9. Automatic Packaging System – The Final Link of Finished Product Delivery
All qualified bottle caps after inspection are delivered to the automatic packaging system to complete full-automatic counting, cartoning, sealing and packaging. The whole process requires no manual intervention, avoids secondary pollution, and greatly improves packaging efficiency. It can be directly connected to warehousing and delivery links, realizing closed-loop automated production from raw material incoming to finished product delivery.
Optional Configuration: Independent automatic packaging system is available, which can be separately configured according to customer production capacity and packaging specifications to adapt to different warehousing and delivery scenarios.
