Description

Crucible type vacuum metalizing machine
Application:
gold or silver coating. Also used for PET plastic film
 
Foreword:
Vacuum chamber: rectangle or round chamber type    
Application: gold or silver wire coating     
Performance: faster, higher ,efficient, much stable      
Advantage: better uniformity, no sputtering ,no pin hole, better fastness of coating          film layer.
Control system: SIEMENS structure, PLC control, higher accuracy AC variable frequency consistent tension winding system
Vacuum system: equip big power pump group and Polycold, suitable for any environment.
Induction heating type evaporating source is applied to coat Al film with winding vacuum metalizing machine. put the crucible of Al ingot into the central of wire coil(not touch),connect high frequency inside the wire coil, make Al ingot produce current and heat it temperature until evaporating. induction coil is made of copper pipe and filled with cooling water. in order to make film layer much uniformity, each power of crucible coil could be controlled separately ,this equipment its evaporating rate is *0 times bigger than evaporating boat.
evaporating source: high frequency induction heating, graphite crucible induction heating, avoid traditional thickness, make sure least pin hole, winding speed up to ***1m/s, totally meet market requirement.
High quality core parts:1, GERMANY  Leybold pump 2, Imported SKF bearing 3, High quality Polycold system  4, Main and sub roller cooling system
Feature:
1. All kinds of crucible coil can be adjusted separately in order to distribute vacuum coating film uniformly.
2. Evaporation speed is fast, so film and wire deviation, wire stuck and block wire fault would not exist. And the filigree yields of thickness distribute evenly to avoid burning of plastic. The quality of coating is more excellent, the phenomenon of the pin hole is less.
3. The evaporation rate of induction-heating roller coating machine is large. It is about *0 times larger than resistance heat source of evaporation boat.
4. In contrast with resistance heating coating, the distinguishing feature of vacuum metallizer equipment is that aluminum block could be enough dissolution and degassing, then form into the stable molten pool and eliminate the sudden sputtering of big droplet.
5. Evaporation source is filled with charge materials. The operation is simple and the temperature is easy to control. The source has much less strict requirements for purity aluminum ingots
