Annealing Lehrs

RōBEX knows glassmaking and has decades of experience in helping maintain production lines. Our deep understanding and skills are something the industry counts on. As production partners, we know what it takes to produce high quality bottles, containers, packaging and more.


Fluctuating lehr temperatures can destroy quality end product. One solution is the proprietary RōBEX Mastermind™ 2000 ATC (patent pending) which controls lehr temperatures to within plus or minus 20º F. Typical result: optimized post-production spray operations, immediate productivity gains and a typical ROI of less than 90 days.


Lehr Services

RōBEX has tremendous experience and expertise in the glass production process. We know maintaining optimum lehr output is an ongoing challenge. Our customer-partners count on us for repairs, maintenance, upgrades of older generation controls and complete rebuilds.



Updating legacy controls results in notable production gains. RōBEX often installs and programs advanced PLC controls with user-friendly HMI screens, ATC units and can train staff.  We work with both off-the-shelf controls or can fabricate/install customer-designed controls.


External and internal audits and production consultation often lead to performance and control upgrades. As part of our comprehensive service, RōBEX offers on-site training and annealing setup assistance. 


RōBEX is the best choice for rebuilds of any annealing lehr. Our decades of experience, understanding and expertise assures a timely professional rebuild. We also install replacement belts, calibrate burners and more. 


RōBEX offers periodic maintenance, urgent repair, surface treatment installation, conveyor maintenance and upgrades. When critical components fail, RōBEX can respond with in-plant service and/or replacement parts. For parts needs, call 419-270-0770 or email
