description
Windshield serial bending furnace repeatability requires stability from the process and perfect controls of all process variables. In serial bending furnaces the nature of continuous, speedy production, and improved automation leaves less room for operator dependent process variables and automation can correct the variations. Nevertheless serial bending furnace production process stability requires perfectly optimized production set-up, perfectly adjusted furnace parameters, perfected heating element configuration, skilled and active operators, continuous process control, and careful production planning. I have recognized in my field work that serial furnace bending process quality has often room for significant improvements that can improve repeatability, quality and capacity. This training program explains the fundamentals of serial bending furnace production and takes the participants through the entire bending process cycle, from loading to unloading, explaining each stage in detail, basic and advanced actions at each stage, tips how to control geometry and size, introduces common mistakes and ways to control process variation.
