Graco InvisiPac HM25c Tank-Free Hot Melt Dispensing System - Configurable

InvisiPac HM25c Tank-Free Hot Melt System for End-of-Line Packaging

The Graco InvisiPac HM25c is a tank-free hot melt dispensing system engineered for easy installation at end-of-line packaging operations that require higher throughput and expanded dispense capability. Delivering up to 25 lb/hr (11.3 kg/hr) of hot melt adhesive and supporting four to eight dispense channels, the HM25c is well suited for mid- to high-volume case and carton sealing where consistent adhesive flow and system flexibility are critical.

Using Tank-Free™ melt-on-demand technology and a first-in, first-out (FIFO) melt process, the HM25c supplies hot melt adhesive as needed to help reduce waste and minimize adhesive charring and thermal shock. The system reaches operating temperature in approximately 10 minutes and features a patented self-learning feed algorithm that automatically delivers adhesive pellets to the melter without operator intervention. Advanced control options, including pattern control and robust reporting capabilities, provide visibility into system performance to support improved efficiency, reduced downtime, and increased productivity on the packaging line.

HM25c Hot Melt Adhesive System Benefits

• Higher Throughput for End-of-Line Packaging: Delivers up to 25 lb/hr (11.3 kg/hr) of hot melt adhesive to support mid- to high-volume case and carton sealing operations.
• Melt-On-Demand Tank-Free Technology: Supplies adhesive only as needed to help reduce waste while minimizing adhesive charring and thermal shock common in traditional hot melt adhesive systems.
• Expanded Multi-Channel Capability: Supports four to eight dispense channels, allowing a single hot melt dispensing system to serve multiple applicators or packaging stations.
• Fast Startup for Increased Uptime: Reaches operating temperature in approximately 10 minutes, helping packaging lines return to production quickly.
• Automated Self-Learning Feed System: Uses a patented feed algorithm to automatically deliver adhesive pellets to the melter without operator intervention, improving consistency and reducing manual handling.
• Advanced Pattern Control Options: Enables conversion from solid bead to stitched bead patterns at the push of a button to support material savings and application flexibility.
• Performance Visibility and Reporting: Provides robust reporting capabilities to help identify opportunities to improve efficiency, reduce downtime, and increase overall packaging line productivity.
