Production-side Issues

The traditional model relies heavily on manual labor, leading to unstable precision in processes such as cutting and corner assembling (errors exceeding ±0.5mm), with a rework rate as high as 15%. There is no automated connection for material flow, resulting in chaotic production cycles and an equipment utilization rate of only 65%.

Other Bottlenecks:

Order response lag: Production line changeover takes 4–6 hours, making it unable to adapt to high-end customized orders. Long delivery cycles have led to a decline in customer satisfaction.
Talent shortage: A 30% shortage of skilled technicians and intelligent operation & maintenance personnel has resulted in idle production capacity coexisting with order backlogs.
Environmental pressure: Emissions from traditional processes struggle to meet standards. In 2023, the number of enterprises failing environmental compliance increased by 20%, further compressing production capacity.
02.
