三. Production Efficiency FAQs

Q3: What’s the output advantage of 4C4H four-airbag design compared with 2C2H models?

A3:Four hot stations and four cold stations work synchronously, single operator can control all stations at the same time, and the daily output reaches 2000 pairs, which greatly improves production efficiency and is suitable for medium and large-scale shoe factories with large order volume.

四.Core Mold Feature FAQs

Q4:What is the advantage of integrated airbag cold mold structure?

A4:Equipped with four independent integrated airbags for cold forming. Only cold inner molds need to be replaced when switching shoe styles without customizing outer molds. Omni-directional air pressure wrapping makes the heel evenly stressed without indentation and wrinkling, and the shaping effect is stable.
