Stacking doors 
 Accumulation of doors, also known as "soft curtain accumulation of doors" and "rapid accumulation of doors" 
 Aust door automatic doors with soft door curtain accumulation of heat, cold, insects, wind, dust, noise, fire, anti-odor lighting and many other features, and is widely used in food, chemical, textile, refrigeration, electronics , printing, supermarket refrigeration assembly, precision machinery, logistics, warehousing and other places, for the logistics channel, large hole, and so require a higher wind outside the door. Performance can be improved to meet the logistics and clean place, and save energy, improve air-conditioning effect, high-speed automatic shut down and improve the role of efficiency advantages. 
 Quick On: accumulation of stacked open and close, open the speed of 0.8-1.4m / s; closing speed of 0.5-1.0m / s. 
 Thermal energy: the door opening and closing function of the rapid increase in temperature in summer and winter insulation effect, reducing energy loss, and saving energy. 
 Seal cut off: the bottom of the PVC fabric with a flexible gas seal, which can be used with a variety of sophisticated combination of uneven ground, up to ten thousand standard, post-specific double brush seals increased by a better seal. Unique sealing system, efficient sealing method, the maximum block the movement of hot and cold wind, to prevent external dust and insects to enter and effectively cut off from the smell, the noise transmission. 
 Safety performance: frames and door box is made of high-quality 2.0-2.5mm thick cold rolled plate steel, high-quality baking, painting Process; 2.0-2.5mm or 3.5mm thick stainless steel high-strength 6063 aluminum alloy column chemical oxidation. 
 Power system: mainly brakes, motors, gear machine. 
 Control system: PLC and Inverter technology.
