We have specialized engineers to design and manufacture automatic plants with various processes as per customers requirement.This plant consists of several processes which are made into one by our specialized design.

A single continuous powder coating process, whereby items are attached toan automated track, which subsequently travels through four separate powder coating process stages.This process delivers apre-treated and finished powder coated component at the end of the track.

Process One - Pre-treatment
Pre-treatment is a five stage process comprising of the following:
Stage 1:Is a highly Alkaline cleaner for steel alloys and zinc-coated steels
Stage 2:Cold rinsing from the main water supply.
Stage 3: Rinsing with De-mineralised water
Stage 4: silane-based multi-purpose liquid pre-paint treatment
Stage 5: Single ring rinsing with De-mineralised water

Process Two – Drying
A drying oven set at approximately 180°C complements the pre-paint treatment and rinse water process, to give an ideal substrate for powder application.

Process Three – Powder application
A combination of automatic and manual spray operations ensures that a controlled and consistent powder film build is achieved.
Aswork passes through the spray booth, controlled amounts of powder are applied by automatic Electrostatic spray guns mounted on reciprocators.Difficult areas not reached by this process are coated by an independent manual spray gun.

Process Four – Curing

After powder coating, the work pieces pass through a gas fired tunnel oven.
The deposited powder film flows then cures as the metal temperature increases to that recommended for the powder applied. During the course of this process, the particles of powder bond together to produce a continuous smooth finish.
