Gachn Valve Sack Making Machine: Flexible Adaptation for Multi-Industry & Multi-Spec Production

Core Industry Pain Point: Fragmented Orders Become the Core Bottleneck of Capacity Upgrading for Small and Medium Packaging Factories

In powder industries such as cement, chemicals, grain and minerals, the order structure is rapidly shifting to a fragmented model of small batch, multi-specification and multi-material, and small and medium packaging factories are generally facing the adaptation problem of traditional bag-making equipment.Traditional bag-making machines only adapt to the single material of PP woven fabric, and have extremely poor compatibility with kraft paper, composite film and other materials; single specification change requires manual adjustment of molds and heat sealing parameters for more than 30 minutes, and the time of order change for small batches is much longer than the production time; the scrap rate of small batch startup soars to more than 5%, and frequent changes will aggravate equipment wear, increasing annual maintenance costs by 40%, which is completely unable to adapt to the flexible production needs of multi-industry and multi-batch.

Core Solution: Full-Servo Intelligent Flexible Valve Sack Making Machine

Gachn Group's full-servo intelligent flexible valve sack making machine is deeply customized for the fragmented order production needs of multiple industries. Equipped with self-developed intelligent changeover system and multi-material compatible technology, it completely solves the pain points of multi-spec flexible production from three dimensions: changeover efficiency, material adaptation and loss control.

Key Performance Advantages

Ultra-Fast Changeover, Zero-Adjustment Adaptation: Equipped with a graphic intelligent control system and modular quick-change molds, full parameter switching of bag specifications is completed in 3 minutes, which is 90% more efficient than traditional equipment. No manual adjustment by professional technicians is required, and ordinary operators can complete the operation.

Full Material Compatibility, Multi-Industry Adaptation: It can seamlessly adapt to 6 categories of mainstream packaging materials including PP woven fabric, kraft paper, aluminum-plastic composite film and non-woven fabric, with a bag width adaptation range of 300-650mm and a bag length adaptation range of 400-1000mm, covering the production needs of valve sacks in cement, chemical, grain, mineral and other industries.

Low Loss & Stability, More Cost-Effective for Small Batch Production: The scrap rate of small batch startup is stably controlled within 0.8%, which is more than 80% lower than that of traditional equipment; the core servo system adopts Schneider brand, and the whole machine has a Mean Time Between Failures (MTBF) of more than 6000 hours, which can maintain stable operation even under frequent changeover conditions.

High-Speed Mass Production, Compatible with Large and Small Orders: The stable running speed reaches 100-110 pcs/min, and the daily capacity of single specification exceeds 130,000 pcs. It can not only undertake large-volume stable orders, but also quickly respond to small-batch customized orders, realizing no waste of production capacity for large and small orders.

Intelligent Linkage, Full-Process Efficiency Improvement: It can be connected with the front-end printing machine and the back-end palletizer to realize unmanned circulation of the whole bag-making process; optional visual inspection system can automatically identify bag type deviation and edge sealing defects, and the finished product pass rate is stably ≥99.3%.

Customer Validation: Proven for Multi-Industry Flexible Production

A comprehensive packaging enterprise in Zhejiang serves more than 20 downstream customers in cement, chemical, grain and other industries, with an average of more than 80 valve sack orders of different specifications and materials per month. Previously, order delivery delays occurred frequently due to slow changeover and high scrap rate. After the introduction of Gachn's flexible valve sack making machine, the order changeover efficiency increased by 90%, the comprehensive scrap rate decreased by 78%, the monthly order acceptance volume increased by 60%, and the annual comprehensive income increased by more than 600,000 yuan. Up to now, this model has served more than 120 packaging enterprises in various domestic industries, and has been exported to 15 countries and regions including Southeast Asia, the Middle East and South America.
