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
