Complete Surface Treatment! Which materials are suitable for different surface treatments? Which products are commonly used? (1)

1  Vacuum Plating

Vacuum electroplating is a physical deposition phenomenon. That is, argon is injected in a vacuum state, and the argon hits the target. The target is separated into molecules, which are absorbed by conductive goods to form a uniform and smooth metal like surface layer.

Advantages: high quality, high brightness and product surface protective layer

Typical applications: surface treatment of reflective coatings, consumer electronics and heat shields

Applicable materials:

1. Many materials can be vacuum plated, including metal, soft and hard plastics, composite materials, ceramics and glass. Among them, aluminum is the most commonly used for electroplating surface treatment, followed by silver and copper.

2. Natural materials are not suitable for vacuum electroplating, because the moisture of natural materials will affect the vacuum environment.

2  Pad printing

he pad printing process can print words, graphics and images on the surface of irregular objects, and is now becoming an important special printing.

Advantages: clear printing details can be achieved, even on uneven surfaces

Typical application: used for surface printing of vehicle interior, electronic consumer products and sports equipment

Applicable materials: pad printing process can be used for almost all materials, except for materials softer than silicone pad, such as PTFE.

3 Galvanized

Galvanizing process is a surface treatment technology to coat a layer of zinc on the surface of iron and steel alloy materials for aesthetic, rust prevention, etc. The zinc layer on the surface is an electrochemical protective layer, which can prevent metal corrosion. The main methods are hot galvanizing and electro galvanizing.

Advantages: perfect protective layer, the appearance largely depends on the quality of steel

Typical applications: surface treatment of buildings, bridges, vehicles and furniture

Applicable materials: as the galvanizing process depends on metallurgical combination technology, it is only suitable for surface treatment of steel and iron
