Pre-Treatment System:
Pre-treatment is required to pre condition a surface to be
painted so it accepts a paint film which looks attractive,
adheres well, lasts long and protect what's underneath.
A Pre-treatment system is decided according to the component
to be powder coated. For ferrous metals, Phosphate coating
prior to painting is suitable and for non-ferrous substrates
like aluminum, chromate coating offers the most appropriate
pre-conditioning.
Since the most correct and economical pre- treatment method
may vary widely case to case, please consult us on the most
optimum solution.
We manufacture and undertake installation of complete metal
treatment system according to your requirement.
Air Compressor :
An air compressor is required to deliver continuous compressed
air to the process. The compressor must deliver oil and moisture
free air.
Oil and Moisture Separator / Air Dryer:
An oil and moisture separator or Air Dryer required to remove
contaminants from compressed air before feeding it to the
process.
Powder Spray Equipment :
An electrostatic powder spray gun is required to spray and
charge the powder to the component.
Powder Spray Cum Recovery Booth :
The component to be powder coated is first hanged in the powder
spray booth and then coated by a powder coating equipment.
Over-sprayed powder is collected by Spray Booth for subsequent
reuse. A good powder recovery system can re-collect over sprayed
powder up-to 98%. The recovery system may be:
(1) Filter Cartridge type- Suitable for one or two powder
colors.
(2) Cyclone Type – Suitable for frequent color change.
Powder Curing Oven:
An oven is required for curing of powder. This may be electrical
or oil fired or gas fired. 180?C to 225?C temperature is required
for powder curing according to powder quality.
Conveyor / Monorail:
For moving the work-piece from pre-treatment tanks to spray
booth and from spray booth to the oven, a conveyor or monorail
is required. For a batch type coating unit, conveyor is not
required.
