Manufacturing Technique

First, The Raw Material Coil Input, Is The Uncoiler Continuous Rewinding To Ensure Continuous Transmission Of The Coil With A Stable Inputting To Production Line. Second, Surface Cleaning And Chemical Treatment, Is To Clean And Chemical Pretreatment The Top And Bottom Faces Of The Aluminum Coil In Order To Ensure That The Paint Can Be Firmly Attached The Coil. The Third Is Painting. Each Production Line Should Have At Least Two Roller Coating Machine To Ensure Prime And Top Coats Can Be Two Layers Coated. Forth Is The Paint Layer Curing That Is The Roll Coil Which Is Finished Painted Just Now Should Be Completed Curing Before Touch The Next Roller To Avoid Mutual Adhesion And Destruction. Generally, It Has At Least Two Curing Boxes In A Production Line. Fifth, Refers To Finished Products Output. It Should Ensure The Production Line's Speed And Finished Coil Transfer Synchronization.TestingPOLYESTERItemTechinical requirementsItemTechinical requirementsThickness of coating film≥18Flexibilty≤2TGloss deviationGlossGloss≥70.Limit of error≤5%Boiling water resisitance2H No color changeHardness pf pencil≥2HColor difference△E≤2.0Adhesion≥1LeverMEK≥150 TimesProduct packaging
