Our neck trimming machines combine precision engineering with practical design to deliver reliable performance in demanding production environments.
High-precision cutting blades with adjustable depth control ensure consistent trimming quality. The system maintains ±0.1mm accuracy across all bottle types, ensuring perfect neck dimensions for proper sealing.
Tooling and fixtures customized for your specific bottle types and sizes. Quick-change tooling system allows fast switchovers between different bottle designs, minimizing downtime in multi-product facilities.
304 stainless steel cutting components and heavy-duty frame ensure long service life and minimal maintenance. Food-grade materials and hygienic design make it suitable for beverage and food packaging applications.
Consistent, precise neck trimming helps ensure proper cap sealing and reduces leakage issues, supporting overall product quality in beverage, chemical, and cosmetic packaging.
Every KSY neck trimming machine is tailored to your specific bottle types and production requirements. We work closely with you to design the optimal solution.
Custom cutting tools and fixtures designed for your exact bottle neck dimensions, thread patterns, and material characteristics. We analyze your bottle samples to create perfect-fitting tooling.
Adjustable mechanisms to handle various bottle sizes within your product range. Quick-change systems for facilities producing multiple bottle types on the same production line.
Choice of control systems from basic manual controls to advanced PLC systems with touchscreen interfaces, production counting, and quality monitoring features.
Customized bottle handling systems including conveyors, positioning mechanisms, and ejection systems tailored to your production line layout and bottle characteristics.
The neck trimming process follows a precise sequence to ensure consistent quality and reliable operation in plastic bottle production.
Bottles are precisely positioned in the trimming station using custom-designed fixtures that match your bottle shape and size. The positioning system ensures consistent orientation for accurate trimming.
The system identifies the excess plastic (flash) around the bottle neck. Advanced systems may include vision systems or mechanical sensors to ensure proper alignment before trimming.
Custom cutting tools remove excess plastic with precise depth control. The cutting action is carefully controlled to avoid damaging the bottle threads or creating rough edges.
After trimming, any remaining burrs are removed, and the neck area is cleaned of plastic particles. Some systems include vacuum extraction to remove trimming debris automatically.
The trimmed bottle is inspected (manually or automatically) and ejected from the machine. Advanced systems may include quality monitoring features to track trimming consistency.
