Customer Background

Anneng Glass specializes in high-end architectural curtain wall and door-window glass tempering, serving leading domestic real estate developers and premium commercial complexes.

Lately, Anneng has faced a significant shift: more SKUs, smaller batches, and constant changeovers. Under conventional production logic, the same glass type must be processed in one dedicated run—and whenever a changeover was needed, the entire line had to halt.

"The real problem wasn't the changeover itself—it was the dead time behind it," an Anneng manager explained. "Parameters had to be reset. Then we had to wait for the furnace to stabilize at temperature. Each changeover consumed half an hour. That's where our efficiency was bleeding out."

Worse, this workflow depended entirely on skilled operators. "Parameters were adjusted by our technicians manually," the manager admitted. "Everything ran fine when they were around. When they weren't, production just waited. Our production cadence was held hostage by specific individuals."

Anneng needed a fundamentally different approach to flexible multi-product manufacturing.

 

 

Ultimate Stability, Safeguarding Every Inch.

Sateak's answer was its proprietary Intelligent Multi-Station Alternate Tempering system.

The core capability: the equipment intelligently matches tempering parameters for different glass types, enabling continuous insulating glass production with "one furnace clear, one furnace LOW-E" running entirely unattended. Glass moves through the line in continuous flow without processing interruptions.

"When Sateak's team first presented this, we were skeptical," the Anneng manager recalled. "After years of manual parameter adjustment and changeovers, being told it would be hands-free—we weren't sure."

But after Sateak ran a full on-site demo, Anneng was convinced. "They executed a live switch—clear glass to LOW-E—with parameters auto-adjusted and furnace temperature auto-matched, zero human intervention," the manager described. "Everyone watching immediately recognized: this is exactly what we needed."

 

Solutions

Results after commissioning exceeded expectations.

The numbers speak clearly: while maintaining high-quality large-format glass output, Anneng achieved over 20% production efficiency gains and 5–10% lower energy consumption, with four operator positions no longer required.

"All three pain points solved in one shot," the Anneng manager summarized. "No more changeover stops. No more furnace idle cycles. No more dependency on specific technicians. And the glass quality? It's actually better than before."

He added: "Higher efficiency, lower energy use, stable quality—this represents a real step-change in our operating cost structure."
