Metal Finishing Services
Protect your metal parts from corrosion, wear, and weather with expert finishing solutions.
Light Metals Coloring (LMC) delivers precision-engineered metal finishing services tailored to your industry’s toughest demands.
Why Metal Finishing Matters
Metal finishing is the critical final step that protects components from corrosion and wear while enhancing functionality and aesthetics. Without it, even the most advanced metal parts would degrade quickly. Whether it’s improving torque tolerance or enabling paint adhesion, finishing ensures your parts perform reliably—and look great doing it.
Key Benefits of Metal Finishing
- Corrosion & Wear Resistance - Shields metal parts from rust, chemical exposure, and mechanical damage to significantly extend their lifespan.
- Enhanced Performance - Improves key surface properties like hardness, lubricity, and electrical conductivity or insulation—crucial for high-performance applications.
- Better Adhesion for Coatings - Prepares surfaces for superior bonding of paints, adhesives, or secondary coatings—resulting in longer-lasting finishes.
- Improved Appearance - Achieve clean, reflective, colored, or branded finishes for both aesthetic and commercial value.
Our Metal Finishing Services & Capabilities
At Light Metals Coloring (LMC), we provide a full spectrum of metal finishing processes designed to meet a wide range of material, industry, and performance requirements. Whether you need precise corrosion resistance or standout appearance, we tailor our services to your specs.
Anodizing (Aluminum Finishing)
Anodizing is an electrochemical process that thickens the natural oxide layer on aluminum. It enhances corrosion and wear resistance, allows for vibrant coloring, and creates a sleek, metallic aesthetic. Ideal for aerospace, electronics, and consumer products.
Manganese Phosphating (Steel Finishing)
This conversion coating is primarily used on steel to protect against corrosion and improve wear resistance. Often paired with abrasive blasting, it also provides excellent lubricity and a reliable base for oil, paint, or dry film lubricant coatings.
Other Finishing Services
Beyond anodizing and phosphating, Light Metals Coloring offers a variety of other finishing services. These include laser engraving, paint infill, powder and dry lubricant coatings, and more. We strive to design custom solutions to meet our clients’ needs and are always expanding our service offerings to provide state-of-the-art finishing processes.
Additional Finishing Services
- Dry Film Lubricant & Powder Coatings – Our friction-reducing coatings extend part life and performance in extreme environments where traditional lubricants fail.
- Laser Engraving & Paint Fill – Add permanent, high-contrast markings for traceability or branding.
- Passivation – Our passivation process removes surface contaminants to boost corrosion resistance and meet rigorous industry standards.
- Precision Masking - We protect critical surfaces during finishing with custom masking solutions that ensure function, fit, and visual quality.
- Abrasive Blasting - Abrasive blasting preps metal surfaces by removing rust and contaminants, ensuring better coating adhesion and finish uniformity.
