Products are widely used in packaging, printing, security, textiles, electronics and building materials industries. The main features of winding system: The system uses high-precision winding tributary or AC variable speed frequency modulation, with stable operation and high speed; equipped with high-power, high plating efficiency, film uniformity; each group by the computer wire feeder motor independent control, you can always tune or a separate governor, and a speed display. The main content of the design of the vacuum coating machine winding system structure reasonable design, including vacuum pumping system, the vacuum chamber, the Central Purchasing winding system, aluminum evaporation system, electrical control cabinet, console and other structures deposited design, the vacuum chamber is box-type, was calculated for each group stick winding system, and control of each group, such as a stick of motor power. Vacuum coating chamber typesetting is different in structure, economy, security, comparing various aspects of rationality and eventually come to a reasonable solution. Production process of aluminum thin film: substrate volume →vacuum pumping →heating evaporation boat →aluminum wire conveying →evaporation →cooling →thickness →flattening and rolling.
