Powder Coating

New Powder Coating Production Facility

October 2024

KEWESTA German automated tact line and conveyor

WAGNER With latest generation spray booth using electrostatic application (ESD) method. The gun control allows precise adjustment of all parameters, saved in programs to prevent setup errors. The gun is also equipped with a dual button option allowing two different application modes. This is suitable for parts with irregular geometries.

Why Powder Coating?

Unlike liquid coating application, powder coating is a dry finishing process using powdered coating material. During the process, the powder is applied to the pre-treated surface, melted, then dried and cured to form a protective-decorative coating.

Specialized for Aluminum

All equipment and technology are designed specifically for coating aluminum castings, following all quality standards for the process, which guarantees the quality of our products.

Our Process in Action

Three-Stage Powder Coating Process

Modern automated technology for perfect results

Surface Preparation

Blasting, degreasing, rinsing, passivation and drying for optimal adhesion

Coating Application

Electrostatic application (ESD) with WAGNER equipment for uniform coating

Thermal Curing

Polymerization at 180-210°C for 12-15 minutes for maximum durability

Stage 1: Chemical Preparation of Parts

🔧 Blasting

Pre-treatment with shot blasting machines for surface cleaning

🧽 Degreasing (Tank 1)

Removal of oils, grease, resins and casting residues with mild alkaline cleaning agents. Process takes 2-3 minutes with warm deionized water.

💧 Rinsing (Tanks 2-3)

Double rinsing with deionized water (15-30 microsiemens) for guaranteed removal of agents. Total time: 4 minutes.

🛡️ Passivation (Tank 4)

Application of a thin protective layer for improved adhesion and anti-corrosion protection. Time: 3 minutes.

💧 Rinsing with deionized water (Bath 5)

Rinsing with deionized water for additional protection.

🌡️ Drying

Drying at maximum 105°C to preserve the passivation layer and ensure optimal adhesion.

Stage 2: Electrostatic Application (ESD)

❄️ Cooling

Parts are cooled after drying for quality coating application

🎯 WAGNER Spray Booth

Latest generation equipment with precise control and programmable settings. Dual mode option for complex geometries.

⚡ Electrostatic Gun

Uniform distribution of powder coating through electric charge, adapted to the part configuration

Stage 3: Polymerization and Quality Control

🔥 Specialized Furnace

Temperature 180-210°C according to powder coating manufacturer guidelines. Minimum 12-15 minutes dwell time.

⏱️ Optimized Time

Time depends on the size, shape and thickness of the part - thin-walled parts require less time

❄️ Cooling and Packaging

Controlled cooling and professional packaging for protection of the finished product
