Powder Coating Plant – Specialized for Low Voltage Switchgear Sheet Metal Enclosures

At NEC, our dedicated Powder Coating Plant is engineered specifically to meet the stringent quality and performance standards of low voltage switchgear sheet metal enclosures. We understand that surface treatment is critical in ensuring both the functional reliability and aesthetic appeal of electrical enclosures, especially in demanding industrial and infrastructure environments.

Key Capabilities

Tailored for Electrical Enclosures: Designed to handle various sizes and configurations of low voltage switchgear panels, ensuring full coverage of edges, corners, and internal surfaces.

Multi-Stage Pre-Treatment Line: Our 7-tank pre-treatment system ensures excellent surface preparation, including degreasing, phosphating, and deionized water rinsing — critical for strong powder adhesion and corrosion resistance.

Electrostatic Powder Application Booths: High-performance spray systems ensure even coating thickness and excellent edge retention, reducing the risk of rust or chipping in service.

Controlled Curing Ovens: Calibrated ovens ensure precise curing cycles for a uniform and hardened finish, with excellent electrical insulation properties.

High Durability Finishes: Coatings meet or exceed industry standards for resistance to salt spray, humidity, and chemical exposure — essential for safe and long-lasting operation in electrical environments.

Benefits for Switchgear Applications

Corrosion Resistance: Prolongs enclosure life, especially in industrial or outdoor installations.

Electrical Safety Compliance: Powder coatings used are non-conductive and meet required insulation standards.

Custom Color Options: RAL-compliant color systems for functional coding and branding.

Precision & Consistency: Critical for maintaining grounding paths and tolerances for door, gasket, and panel fittings.

Eco-Friendly Process: VOC-free coating method with recyclable overspray, aligned with modern sustainability practices.

Our in-house powder coating facility plays a crucial role in delivering safe, durable, and visually consistent sheet metal enclosures that meet the expectations of OEMs, panel builders, and electrical contractors. It supports our promise of delivering turnkey quality and reliability for every enclosure system we manufacture.
