We have specialized engineers to design and manufactureautomatic plantswith various processes as per customers requirement.Thisplant consistsof several processes which are made into one by ourspecialized design.
asingle continuous powder coating process, whereby items areattached toan automated track, which subsequently travels through fourseparatepowder coating process stages.This process delivers apre-treated andfinished 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 thepre-painttreatment and rinse water process, to give an ideal substratefor powderapplication.
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 powderareapplied by automatic Electro-static spray guns mounted onreciprocators.Difficult areas not reached by this process are coated byanindependent manual spray operation.

Process Four – Curing
After
powder coating, the work pieces pass through a gas fired tunnel oven.
Thedeposited powder film flows then cures as the metaltemperatureincreases to that recommended for the powder applied. Duringthe courseof this process, the particles of powder bond together toproduce acontinuous smooth finish.
