Surface Finishing & Coating Options
Explore our full range of metal, plastic, and mold surface finishes to enhance durability, appearance, and performance. From precision polishing to protective coatings, we deliver finishes tailored to your application and production requirements.
As Machined
Machined parts delivered with visible tool marks, ideal for functional prototypes.
Sand Blasting
Matte finish with uniform texture, removes sharp edges and light defects.
Tumbling
Smooths edges and polishes surfaces, ideal for small parts in batches.
Electropolish
Electrochemical polishing that brightens and smooths metal surfaces.
Heat Treatment
Improves hardness, strength, or ductility through controlled heating and cooling.
Black Oxide
Adds a black coating to steel for mild corrosion resistance and reduced glare.
Anodizing
Durable oxide layer on aluminum with optional color for corrosion protection.
Alodine
Chromate conversion coating for aluminum to resist corrosion and improve paint adhesion.
Teflon Coating
Non-stick, low-friction coating with excellent chemical resistance.
Electroless Plating
Uniform nickel-phosphorus coating without electricity, resists wear and corrosion.
Electroplating
Adds a thin metal layer for improved appearance and wear resistance.
Painting
Protective and decorative color coating for metals and plastics.
Powder Coating
Durable, chip-resistant coating for a uniform colored finish.
Electrophoresis
Even thin coating for corrosion resistance and decorative appeal.
Brushed Finish
Linear texture for decorative or functional purposes.
SPI & MT Finish
Mold polishing or texturing to meet SPI/MT standards for injection molding, for consistent part appearance and ejection
Not sure which finish to choose?
Different materials and operating environments require different surface finishing processes. Whether you need enhanced corrosion resistance, improved aesthetics, or compliance with industry standards, our engineers can recommend the right solution. Just share your material, application, and appearance requirements, and we’ll match you with the best option.
Surface Finishes - FAQs
How do I choose the right surface finish for my part?
Selection depends on the part’s base material, functional requirements, and appearance goals. For example, anodizing works best for aluminum to improve corrosion resistance, while powder coating is better for durable colored finishes on metals and plastics.
Which finishes are available for plastics?
Painting, powder coating, and certain textured finishes (e.g., SPI & MT) are compatible with plastics. Most plating and anodizing processes are for metals only.
Are all finishes suitable for functional prototypes?
Not necessarily. For prototypes where lead time is critical, simpler finishes like as-machined or sand blasting are faster. Coatings requiring curing, plating baths, or multi-step masking may extend turnaround time.
Can I apply multiple finishes on the same part?
Yes, in many cases. For example, a machined aluminum part can be anodized and then laser-engraved, or plated and then painted. The sequence must be planned during production to avoid damage to prior finishes.
Do surface finishes affect dimensional accuracy?
Yes. Coatings like powder coating or plating add thickness (typically 10–50 μm) which can impact tight tolerances. Machining allowances may be required before finishing.
Are the finishes compliant with RoHS or REACH standards?
Most of our standard finishes can be provided in RoHS/REACH-compliant versions. If you need certifications such as FDA, NSF, or biocompatibility, inform our engineers during quoting.
How durable are the finishes for outdoor use?
Finishes like anodizing, powder coating, and certain electroless nickel coatings offer strong resistance to UV, moisture, and corrosion, making them suitable for outdoor or marine applications. Paint without proper sealing may degrade faster outdoors.
Can you color match finishes to a specific requirement?
Yes. We can match colors using RAL or Pantone standards for painting, powder coating, and anodizing (within achievable limits). Custom colors may require additional lead time.
How do I maintain parts with surface finishes?
Use mild detergents and avoid abrasive cleaning tools. For anodized or coated parts, avoid acidic or alkaline cleaners that could damage the finish.
What’s the typical lead time for finishing?
Basic finishes like sand blasting or as-machined can be done within 1–2 days. Coatings like anodizing, plating, or powder coating may require 3–7 days depending on batch size and complexity.
