This process involves inspecting the materials received from suppliers to ensure they meet the required specifications and quality standards. It may include checking for any physical defects, verifying color consistency, and assessing the overall condition of the materials.

Sandblasting is a surface preparation technique used to clean and roughen the substrate before the coating application. It involves propelling abrasive materials, such as sand or grit, at high speed onto the surface to remove any rust, dirt, or old coatings. Sandblasting helps create a clean and textured surface, providing better adhesion for the subsequent coating layers.

This process involves applying a pre-treatment solution or coating to the prepared surface after sandblasting. The purpose is to enhance the corrosion resistance of the substrate by creating a protective barrier. Common pre-treatment methods include phosphating, chromatin, or applying special chemical conversion coatings.

Powder coating is a dry finishing process where a powdered pigment or resin is electrostatically applied to a grounded object. The object is then heated, causing the powder to melt and form a durable, uniform, and attractive coating. This method offers excellent coverage, adhesion, and resistance to chipping, corrosion, and fading.

After the coating process, quality inspection and testing are conducted to ensure that the coated products meet the required standards. This involves visually inspecting the coatings for any surface defects, checking the thickness of the coating using measurement tools, and conducting various tests to assess factors like adhesion, hardness, flexibility, and corrosion resistance.

Once the coatings have passed the quality inspection, they are properly packaged for shipment or storage. Packaging may involve protective measures such as wrapping, padding, or using suitable containers to prevent damage during transportation. Proper labeling and documentation are also done to ensure the traceability and identification of the coated products.
