Redefining IG production

The 4SG cohesive bond high-speed (CBHS) line is Erdman Automation’s latest breakthrough in insulating glass production—a next-generation thermoplastic spacer system engineered for the window and door manufacturing market. Built on more than 30 years of machinery expertise out of Princeton, Minnesota, the CBHS line represents a fundamental rethinking of how spacer is applied in 4SG production. Rather than a single-sided application, the system uses a dual application design that bonds the spacer to both lites simultaneously, a process innovation that changes the performance equation across the board. 

Speed, strength, and spacer simplicity 

The CBHS line’s dual application approach delivers stronger adhesion, greater design flexibility and dramatically faster handling. Cycle times are reduced by more than 15 seconds per unit, with the line hitting performance targets of 25 to 28 seconds, approximately 40% faster than traditional systems. Operating with just three direct operators, the line increases throughput without adding headcount. The cohesive bond design also unlocks best-in-class thermal performance, reduces visible spacer width for a larger daylight opening, and accelerates triple and thin triple glass production. 

The throughput answer for manufacturers 

For manufacturers, the CBHS line directly addresses the twin pressures of labor constraints and production volume. By achieving 40% faster cycle times with a lean three-operator crew, facilities can scale output without scaling their workforce. The improved bond strength and reduced spacer visibility also help manufacturers meet rising market demands for both performance and aesthetics—offering the possibility of less material use while delivering a superior product. For companies producing triple-pane units, the speed gains are especially significant, making a historically slower format far more commercially viable.
