ometimes a small part can cause big problems in hollow glass production. The post on the blank-side hanger on an individual section (IS) machine can flex and shift over time, which can lead to misaligned plungers and container defects. “The biggest thing hollow glass producers want to do is reduce cost per tonne, that’s what they’re driven toward every day,” says Doug Stanley, Pyrotek’s Global Manager Glass Container Technology and Business Development. “Reducing glass defects and machine downtime can help improve that.” When the blanks close and pressure is
applied, deflection is caused. Pyrotek’s taper lock anti-deflection bracket, which sits atop the hanger saddle, provides an added stability compared to other brackets on the market. It holds the post in place and limits its movement, which improves bracket life and helps prevent defects. It can increase the life of the post, reduce baffle tears, blank tears, and keep traditional bushed or non-bushed brackets from wearing. In addition, the bracket can lead to a lower press pressure setting on the hangers. “The more press pressure on the glass, the more defects will result. The bracket helps keep everything in line with less friction,” Stanley says. The taper lock anti-deflection bracket is designed for certain 8.5-inch tripe glob and 6.25-inch double gob IS machines. It also is included in Pyrotek’s linkage system, which stays centered, maintains ideal closing angles, and ensures one side’s clamping force doesn’t overpower the other. “We offer a complete linkage system,
everything from the toggle shafts, the linkage itself on the blank side, the blank saddle, and the hanger,” Stanley says. “With the bracket, our linkage system has this advantage.” Pyrotek makes the brackets at its plant in Tulsa, Oklahoma, USA. Nearly 200 sections are in service, and it is conducting trials globally. “We’ve done multiple trials, and we’ve never had one returned. Everyone who has done a trial has purchased the part,” Stanley says. �
