Difference between electrophoresis lattice frame and oil spraying of engraved round metal logo-A

Engraved Round Metal Logo’ (Engraved Round Metal Logo) electrophoretic lattice frame and oil spraying (painting) are two different surface treatment processes, the main difference is reflected in the principle of the process, the appearance of the effect, performance characteristics, application scenarios and costs. The following is a specific analysis:

1. Process principle
   Electrophoretic lattice frame (electrophoretic coating)Metal Logo
   Electrophoretic coating is a process of depositing charged paint particles on the metal surface through the action of electric field. The specific process includes:
   The metal workpiece is immersed into the electrophoretic paint tank as an electrode.
   Under the action of DC electric field, the charged resin and pigment particles migrate towards the surface of the workpiece and are deposited.
   After baking and curing, a uniform and dense coating is formed.
   Electrophoretic laths are usually used on metal surfaces to form a protective and decorative coating.
   Oil Spraying (Painting)
   Paint spraying is to spray paint evenly on the surface of the workpiece after atomisation by a spray gun, relying on the adhesion of the paint and the drying process to form a coating. The specific process includes:
   Surface pre-treatment (e.g. degreasing, descaling, sanding).
   Spraying the paint, which usually requires several coats to achieve the desired thickness.
   Natural drying or baking to cure.
   The spray painting process is flexible and applicable to a wide range of materials and shapes of workpieces.
2. Appearance effect
   Electrophoretic lattice frame Metal Logo
   Uniform coating, good coverage of edges and depressions, suitable for complex shaped workpieces.
   Smooth surface with adjustable gloss (matte, semi-gloss, high-gloss).
   Relatively limited choice of colours, but a wide range of colours can be achieved by paint mixing.
   Oil spraying (lacquering)
   Variety of appearance effects, high gloss, matte, metallic, texture effects, etc. can be achieved.
   A wide selection of colours is available, and almost any colour can be achieved by colour mixing.
   The thickness and uniformity of spraying are affected by operating techniques, and defects such as flow marks and orange peel may exist.
3. Performance characteristics
   Electrophoretic lattice frame Metal Logo
   Strong corrosion resistance: the dense electrophoretic coating can effectively isolate the metal from the external environment, suitable for outdoor or humid environments.
   Good adhesion: the coating is firmly combined with the metal substrate and is not easy to come off.
   Environmental protection: electrophoretic paint is mostly water-based, with low VOC (Volatile Organic Compounds) emission, which is in line with environmental protection requirements.
   Abrasion resistance: the coating has high hardness and good abrasion resistance.
   Oil spraying (painting)
   Highly decorative: rich appearance effects can be realised through a variety of processes.
   Weathering resistance: according to the type of paint (e.g. acrylic, polyurethane, fluorocarbon paint), there is a big difference in weathering resistance, and the weathering resistance of high-end paints is excellent.
   Repairability: local damage can be repaired by touching up the paint, but there may be colour differences.
   Abrasion resistance: depends on the type of paint and coating thickness, generally slightly worse than electrophoretic coating.Metal Logo
