SG-3000-1DD is designed by means having solved many problems and difficult basis on decade experience, such as: Polluted glass by excessive adhesive, asymmetrical heating, low production but high energy consume etc. It is equipped with multilayer vacuum beds, and each bed is able to put double units so that the production capacity is double times than normal oven. This is a unique design of SG-3000-1DD.

SG-3000-1DD has the characteristic of short time for heating up and cooling down, even temperature, low costs and low power consume.
