Recently, a customer in Shanghai installed a black protective door on the equipment. Why did the customer not choose a bright color but use a black door curtain? See below for details.

    1. Why do customers choose black rapid doors?

      Because the equipment is installed on a visual inspection equipment, the entire inspection process is very strict and does not allow any light to enter. It is required to be completely sealed and opaque.

      2. Is there any special use?

     The black fast rolling shutter door is opaque. The black curtain will absorb the light source. Any external light source shining on the black curtain will not be able to enter the room. It has good sealing isolation, light blocking and light protection properties.

      The black protective fast door has high opening and closing frequency, fast lifting speed, and multiple compatibility ports, which can meet the needs of continuous processing and testing of the equipment for 12 to 24 hours. The internal and external contact time is short, which does not affect the quality of the product itself. It can also be designed to be opened and closed in a linked manner.
