Hot dip galvanizing
1. surface preparation
The first step is to strip the steel to remove any oxides or contaminating agents such as grease, dirt, rust or scale and immerse the material in a flux bath to stop the oxidation process of iron or steel.
2. Galvanization
In the second stage, the material is ready for hot-dip galvanizing in the zinc bath. During immersion, the material is allowed to reject its evaporations, then slowly remove it and place it in the cooling tank.
3. Finition
At the final stage, we must remove excess zinc, inspect the material and then retouch it if necessary to meet the highest quality standards
Thermoforming
DEFINITION AND PRINCIPLE
Thermoforming is a technique of coating and protection of ferrous and non-ferrous metals. It applies to all black steel, galvanized, electro-galvanized or raw aluminum, anodized or already lacquered metal parts in ventilated cab. It consists of electrostatic deposition of powder paints that polymerize at 200°. The powder particles are charged with static electricity and are attracted to the room to be painted as if they were magnetized. This technique allows to obtain a bypassing effect as well as a very good penetration of the powder in every corner of the parts.
POLYMERIZATION
After powder coating, the pieces are placed in an oven for about 20 minutes at 200° for polymerization. It is this step that hardens the powder and thus stabilizes it. Note: Time and temperature vary according to the density and mass of the parts.
COATING CHARACTERISTIC
The technical and aesthetic performance of powder paints is excellent, particularly as regards:
- The Shock resistance
- The surface hadness
- The resistance to corrosion
- The color fastness
- Coating uniformity (no streaks or overhangs)
- The wide choice of colours (RAL colour chart= more than 160 colours available)
- Possibility of special effects such as metallic, textured or sandblasted effect……
