Web Coater (rolling coater)
High Vacuum Web Coater is specially designed equipment for coating aluminium films or oxidant compound films or other metallic films on rolls of any polyester membranes. It can be also equipped with both wire-feeding system, melting pot or sputtering metallization function as per customers specific requirements to realize specific coating results.
This machine is extensively used for the production of metallic packing materials for food industry, decorative or packing material, electrochemical aluminium material, various labels, sticks and trade marks as well as all kind of reflective material, heat preservation or heat insulation materials and electric material.
Using this equipment, the metal film can be coated by evaporation, DC or MF magnetron sputtering on the surface of plastic, cloth and metal sheet, etc. It can be equipped with both evaporation and sputtering functi*** with efficient vacuum pumps group coupled with.
Its advantages as following:
1, This machine equipped with a set of compound vacuum group with advantages of fast pumping speed, super-exhaustion and high vacuum state by PLC digital control over complete operation, such as pre-heating, pumping speed, pump cooling and problem alarm, etc.
2, The driving setting of double roller for the substrates in this machine adopts vector frequency conversion control system with highly resolve coder to insure, during winding operation, the stability of rolling speed and to eliminate the unf***orable influence caused by voltage fluctuation or loading.
3, The tensile force controller of the substrates is using MITSUBISHI product of close-up digital tension-inspection system, coupled with tension sensor to realize the c***tant tension of release winding in the course of coating operation. It is adaptable for thin, narrow or stretched materials to take vector frequency conversion motor control over release and wind-up rolling and the auxiliary tension tow roller at the side of wind-up roller driven by an independent motor guarantees the high precision of tensile force control.
4, A tracing device equipped on wind-up roller can adjust rolling position as per changes of rolling diameter to maintain c***tant rolling distance.
5, The electric leveling rollers installed at both release and wind-up rollers in substrate rolling system can realize outside angle control and perform leveling effects control as per necessity in the course of coating operation.
6, With effective cryo-freezing/heating device equipped on the main double rollers that may freeze the surface of the rollers to the minus 15 degree centigrade in the course of coating operation, can cool substrates and can make rollers recover normal temperature by heating system after coating operation finished.
7, The chamber of this machine with connecting port for chiller, is ***ailable to install deep chiller system for coating paper.
