Production Line of VCM Household Appliance Plates
VCM film faced plywood (Polyvinyl-Coated Metal Steel) means to coat composite PVC thin film on the metal surface and make them combine firmly, and it is also called PVC film-faced plywood or PET/PVC filmed color galvanized steel plate. The base material can use metal thin plates of cold-rolled steel plate, hot-dip galvanized steel plate, electro-galvanized steel plate, aluminum plate, stainless steel plate, and Ti-Zn plate etc.. VCM has beautiful appearance and excellent processability, surface decorativeness, corrosion resistance and scratch resistance, and can realize different effects from low light to high light, and meanwhile, it is fitted with beautiful patterns and jewelry twinkling effect. Besides, on the basis that the surface film of film faced plywood has features of special processing of printing etc., VCM can show different effects of multiple colors and touch textures. At present, it has been widely applied to household products of refrigerators and washing machines etc..

II. Main Characteristics of Unit
1.The application of undertint patterns and varnish (finishing varnish) on the existing color base makes the plate appear luxury and bright, and the unit is characterized in bright colors, prominent arrangement, good visual effect and flashing function.
2.The color-coated steel plate itself has good mechanical performance and machine-shaping performance, and with beautiful modeling design, it can be used in decorative situations of package box, and achieves the aim of beautifying the commodities and improving the commodity competitiveness.
3.The selection of base material for color-coated printed steel plates is very strict, the electro-galvanized sheet or cold-rolled sheet and galvanized sheet (small spangles or no spangle) can be used. The plates are better to be subject to finishing treatment, and the straightness of the base material surface has high requirement.
III. Production Process Flow:
Hand-feeding → uncoiler unit → shear → sewing machine → front looper → alkaline washing unit → water washing unit → hot-air blowing device → chemical roller-coating machine → chemical-coating drying furnace → prime-coat roller-coating machine → prime-coat curing furnace → air cooling → water cooling → drying → top-coating roller-coating machine →top-coating curing furnace → air cooling → water cooling → drying → printing machine unit (preserved location) → over-coat roller coating machine → over-coat curing furnace → hot film laminating machine → over-coat (laminated film) forced cooling room → drying → cold film laminating machine → rear looper → shear servo coiler unit → hand unloading
