The difference between painting and plating
Author: Robby
Spraying and plating have their own advantages and disadvantages, as follows
Advantages of spraying:
Flexible and convenient operation, applicable to different environments, shapes and sizes of products.
Simple equipment, low energy consumption.
It can be used on metal, alloy, plastic, ceramic and other workpieces to improve their corrosion resistance, heat resistance, wear resistance and other properties.
Common spraying methods include gas combustion flame spraying, gas discharge thermal spraying, electric arc spraying, plasma flame spraying and so on.
Disadvantages of spraying:
Lower production efficiency.
Unstable spraying quality.
Worker labor intensity, vulnerable to paint pollution, poor labor conditions.
Advantages of electroplating:
Plated metal or other insoluble materials as the anode, the workpiece to be plated as the cathode, the cation of the plated metal in the surface of the workpiece to be plated by the reduction of the formation of the plating layer, the surface is brighter, better mirror effect.
Applicable to metal or part of the non-metallic materials, to improve its decorative, conductive, reflective, corrosion resistance and other properties.
Common plating methods are chrome plating, galvanizing, copper plating, gold plating and so on.
Disadvantages of electroplating:
Requires wastewater treatment equipment and is less environmentally friendly.
Contains heavy metals and has three waste emissions.
Larger investment in equipment.
