Crafted through precision stamping and moulding techniques, the machine’s sturdy frame minimizes packaging errors while enhancing reliability and long-term durability under industrial use.
Intelligent Network Integration
The host machine, conveyor, sewing unit, and control panel are interconnected to support intuitive, centralized operation—reducing manual labour and boosting overall workflow efficiency.
Spill-Resistant Handling
An anti-spill mechanism effectively prevents powder leakage and bag flipping during pneumatic bag opening, promoting a cleaner, safer working environment.
Smart Production Management
Automatically tracks shift-wise, daily, and cumulative production data, enabling real-time monitoring and improved decision-making on the production line.
Simplified Maintenance
Compact, accessible components allow for easy cleaning and maintenance, minimizing downtime and extending equipment lifespan.
User-Friendly Operation
Combining manual bag placement with automated weighing, filling, and sealing, the system streamlines packaging tasks—greatly improving productivity with minimal training required.
