Frequently Asked Questions
What is powder coating?
Powder coating is a dry finishing process that uses electrostatically charged powder applied to metal parts, then cured under heat to create a uniform, durable finish. It’s ideal for protective and decorative applications.
What materials can you powder coat?
We powder coat a wide range of conductive materials, including aluminum, steel, stainless steel, galvanized steel, and select pre-treated alloys. Non-metallic parts are not compatible.
What colors and finishes are available?
We offer thousands of color options, including RAL and custom-matched shades, with gloss, matte, satin, textured, metallic, and specialty finishes like hammertone and wrinkle.
What industries do you serve with powder coating?
DMF serves aerospace, defense, architecture, commercial, electronics, energy, and OEM manufacturing with finishes that meet industry-specific standards like AAMA 2603/2604/2605.
Can powder coating be applied over anodized or chem film-treated parts?
Yes. Powder coating can be successfully applied over anodized or chromate-converted (chem film) surfaces when properly cleaned and prepped.
What sizes or dimensions can you handle?
We can accommodate large parts up to approximately 96″ L x 60″ H x 36″ W in our curing ovens. Contact us for irregular or oversized part configurations.
Is powder coating suitable for outdoor use?
Absolutely. We offer UV-stable and weather-resistant powder formulations that provide excellent protection against sun, moisture, and extreme temperatures.
How long does powder coating last?
Properly applied powder coating can last 10–20+ years depending on environmental exposure, substrate prep, and coating selection.
What is the typical turnaround time?
Most orders are completed in 5–7 business days, depending on part complexity, masking, and volume. Expedite service is available for urgent requests. Contact us to confirm feasibility based on part complexity and volume.
Can you mask off threads or contact points?
Yes. We offer professional selective masking for threaded holes, grounding surfaces, and tight-tolerance features.
What surface preparation do you provide before coating?
We use a multi-step pre-treatment process, including degreasing, blasting, and chemical etching or conversion coatings to ensure maximum adhesion and corrosion protection.
How thick is the powder coat?
Typical film thickness ranges from 2.0 to 4.0 mils (50–100 microns), depending on part geometry and application needs.
Can you handle production volumes or prototypes?
Yes. We support small-batch prototypes, high-volume runs, and custom color testing for design validation.
Do you meet quality standards or offer certifications?
All coatings are processed under ISO 9001:2015 certification. We also meet AAMA 2603/2604/2605 and can provide CoCs, batch test reports, and PPAPs upon request.
Is powder coating environmentally friendly?
Yes. Powder coating emits no VOCs or solvents, generates minimal waste, and overspray is often recyclable—making it a sustainable alternative to wet painting.
Can powder coating be combined with other DMF services?
Definitely. We integrate powder coating with laser engraving, screen printing, anodizing, and chem film for complete finishing solutions.
What’s the difference between powder coating and painting?
Powder coating offers better durability, chemical resistance, and finish consistency compared to liquid painting, with no drips, runs, or solvents.
Do you offer custom textures or metallic effects?
Yes. We provide textured, wrinkle, hammertone, and metallic-effect powders—ideal for visual branding, grip, or surface concealment.
Will powder coating affect part dimensions?
While minimal, powder coating adds thickness. Tight tolerances should be discussed before coating so we can accommodate design offsets or masking.
Can you match my existing finish or color?
Yes. We offer custom color matching for corporate colors, existing equipment, or finish replication—based on sample or code.
