Powder Coating Strengthens Industrial Parts with Durable, Eco-Friendly Finishes
Powder coating is a versatile, solvent-free finishing process that applies dry resin-based powder to metal and other substrates, producing tough, uniform, and environmentally friendly coatings. Plastonics specializes in applying powder coatings to small parts only—typically under 3 inches or 3 oz—harnessing this method’s strengths for precision and performance in industrial applications.
What Defines Industrial Powder Coating
Industrial powder coating involves several key elements:
- Electrostatic spray or other applicators deliver dry powder onto grounded substrates.
- Curing in an oven enables the powder to flow and chemically cross-link, creating a durable surface.
- The process achieves full encapsulation with thick, resilient coatings while releasing little to no VOCs
It is favored across industries requiring long-term protection and aesthetic quality.
Major Industrial Applications
Appliances
Powder coating secures durable finishes on refrigerators, ovens, washers, dryers, vending machines, and microwave panels. It endures temperature fluctuations and frequent use while resisting chips and corrosion.
Outdoor Equipment & Furniture
Equipment exposed to weather—like farm tools, bicycles, playground structures, and outdoor furniture—benefits from powder coating’s resistance to UV, moisture, and impact.
Architectural & Construction Components
Used on metal doors, fencing, railings, signage, and building panels, powder coatings provide long-lasting protection in harsh or public environments.
Automotive Parts
Used extensively for springs, clips, engine parts, and agricultural machinery, powder coatings offer chemical and weather resistance. Emerging uses include battery packs, bus bars, and chassis, enhancing fire retardance and performance.
Industrial Machinery
Metal cabinets, pipe supports, tool racks, conveyor components, and structural frames gain robust finishes that resist solvents, corrosion, and wear—a vital need in manufacturing settings .
Abradable Coatings
Used in engines, pumps, and compressors, abradable powder coatings reduce friction and enhance efficiency. Initial thick coatings wear in, then stabilize to precise tolerances.
Special Substrates
Advances permit powder coating on glass, composites, wood, and MDF using UV-curable powders, enabling clear or opaque coatings for décor, packaging, and custom industrial needs.
Advantages in Industrial Settings
Durability: Powder coatings resist scratching, chipping, chemicals, and weather—superior to conventional wet paint .
Environmental Benefits: No solvents, minimal waste, and high transfer efficiency support eco-conscious operations .
Cost Efficiency: Overspray is reclaimed, curing is quick, and maintenance is minimal—ideal for high-volume production .
Aesthetic Versatility: Unlimited color, texture, and finish options—from matte to metallic—enhance both function and form .
Consistency: The baking process ensures even thickness and minimal variation across complex or large components .
Process Overview
Surface prep remains critical: cleaning, degreasing, sandblasting, or pretreatments (chemical conversion or plasma) ensure adhesion. Next:
- Powder applied via electrostatic gun.
- Part enters curing oven (usually 160–200 °C for 10–15 minutes).
- After curing, parts cool and undergo inspection for thickness, adhesion, and finish integrity
