In this video, we walk you through the operation of the YT-133C heat setter, an energy-efficient upper shoe heat setting machine used in footwear manufacturing. You'll see how it smooths wrinkles and shapes shoe uppers after lasting, using advanced German technology for high efficiency and eco-friendly performance. We demonstrate its vacuum shaping system, steam spraying process, and energy-saving features that reduce power consumption by over 70% compared to traditional methods.
