Coating process
1. Degreasing / Drying
It is necessary to remove the soil from the parts as treating material which may have some oils while processing. rust prevention oil for protecting the rust before GEOMET®720LS
2. Shot Blasting
The purpose of blasting is to expose fresh metal surface oy femora inorganic so, rust, and scale from the surface of the part by mechanical force. To cos enough sacrificial protection it is necessary to get good contact between zinc and steel surface, for example, the scale could interfere to flow of the electric current.
There are various types of blasting machines used for different types of products.
Hanger type shot blasting
Tumble Type Shot blasting
Table Type Shotblasting
Sandblasting
3. Coating And Curing
The purpose of this process is to apply enough zinc and aluminium flake paint on the parts surface with uniformity.
The processes are largely classified into the following types:
A. Spray method
This coating method is ideal for parts that must maintain a good appearance. Suspend the parts from a hanger and perform electrostatic coating and then bake them in the oven. The standard specification is one coat and one bake.
Basket Spray
In this process chemical is sprayed in a continuously rotating basket.
B. Dipspin Method
Application to bulk quantity(dip-spin ) is carried out in baskets which allow eliminating the excess liquid on the surface of the parts and improving the distribution of the coating
Single Basket Coating Machine
In this process chemical is sprayed under the pressure of atomizing air. It can be carried with pneumatic air guns or electrostatic equipment
3 Basket Robotic Coater
In this process chemical is sprayed in continuously rotating basket.

4. Curing Process
Geomet® film is formed by heat up the metal surface coated with Geomet®. The curing process of Geomet® is consisted with 2 stages. Vaporising water and organic solvent and following film form reaction.
5.Final Inspection
In this stage 100% inspection takes places for coating defects. The approved material is packaged and dispatched.
6. Testing Facilities
Salt spray testing is a laboratory simulation of a corrosive saline environment. It is used as an accelerated means of testing the ability of surface coatings to withstand atmospheric corrosion. Also known as salt fog testing,
