Electrostatic Powder Coating Unit
At first, the aluminum profiles surface are degreased and pre-treatment implemented by sinking n particular solutions and by entering to preheating furnace they are thoroughly dried to get prepared for spray step in this step the profiles are conveyed by 150 meter automatic conveyor line vertically to spray booth and painted by the French “SAMES” full smart machines.
The top features of Alstar Industrial complex painting line are capable of controlling parameters such as dye thickness (micron) inflating pressure ampere and voltage spray intensity and spray speed automatically
Then the painted profiles are transferred to energy saving equipped curing oven and are heated in 180-200 centigrade degree.
Temperature uniformity throughout the curing oven is one of the sensitive points during this process
The sprayed paint thickness is between 60 micron to 80 micron in Alstar Complex
Some tests such as Cross cut (paint adhesion) impact test. coating thickness test salt spray test and conformity test with RAL Colored shade are the responsibilities of quality control (QC) department.
