Metal Spraying Workshop
The Spraying Workshop is a specialized facility engineered for high-efficiency surface coating applications, combining advanced automation, precision processes, and environmental compliance. Below is a detailed breakdown of its operations and capabilities:
-
Pre-Treatment Section
The pre-treatment phase is critical for achieving optimal adhesion and surface quality.
Ultrasonic Cleaning: Components undergo ultrasonic degreasing to remove oils, dust, and contaminants from the fixture surfaces, ensuring a pristine substrate for coating.
Surface Deburring: A combination of overhead shot blasting (for large or complex-shaped fixtures) and tumble blasting (for smaller components) is employed to eliminate surface imperfections, such as burrs, sharp edges, and oxidation layers. This mechanical preparation enhances the substrate’s roughness, promoting better powder adhesion.
-
200-Meter Automated Powder Coating Line
Electrostatic Spray Deposition (ESD): Charged powder particles are uniformly applied to grounded fixtures via automated spray guns, ensuring even coverage and minimal waste.
Thermal Curing: Coated components pass through a convection curing oven at 180–200°C for 10–15 minutes, allowing the powder to melt, flow, and chemically crosslink into a durable, corrosion-resistant finish.
Powder Overspray Recovery: An integrated cyclone separation system and filter recovery unit capture and recycle unused powder, achieving >95% material utilization and reducing waste.

Environmental Compliance
VOC-Free Process: Powder coating eliminates volatile organic compounds (VOCs), aligning with green manufacturing standards.
Emission Control: Advanced filtration systems treat particulate emissions, while wastewater from pre-treatment is neutralized and purified before discharge.
