CRL Glass Machinery Continues to Strengthen its Product Line with the New Upgraded HMCST2 Hot Melt Clamp Sealing Table

Hands-Free Pneumatically Operated Clamp Table Safely Facilitates the Sealing of Insulating Glass Units

LOS ANGELES, CA - JULY 11, 2016 - C.R. Laurence’s Machinery Division (formerly Sommer & Maca) has been a leading manufacturer of glass tools, machinery, and equipment for almost a century. The division is proud to introduce its upgraded HMCST2 Hot Melt Clamp Sealing Table, which is designed to help door and window fabricators safely and efficiently seal insulating glass (IG) units.

The new HMCST2 features heavy-duty tubular steel construction and an 84" x 84" ball caster table with a pair of padded clamping rails. The table’s 2" diameter ball casters are spaced 6" apart from each other. The clamping rails are operated using a pneumatic foot pedal. This new feature frees up the glazier’s hands for positioning of the IG units while holding an edge sealant gun.

To use, the operator simply positions the IG package (glass and spacer) on top of the ball caster table with one edge beneath the padded clamping rails. The foot pedal is then depressed to activate the hands-free clamping mechanism, which secures the glass and spacer along one edge for sealant application. The IG system is then rotated and re-clamped to seal each side. The HMCST2 requires a compressed air supply capable of delivering 1 CFM @ 50 psi.

“CRL continues to build on our long history of machinery manufacturing expertise and quality, American-made products,” said John Czopek, brand manager of CRL Glass Machinery. “As glass technology and capabilities evolve, so too must our ability to provide solutions for common production and manufacturing issues. Our upgraded, hands-free HMCST2 unit is an example of delivering such a solution.”
