Surface Finishing Services

KaiSpeed delivers production-grade cosmetics and protection—enhancing appearance, corrosion/wear resistance, and longevity for machined, sheet metal, molded, and 3D-printed parts.

  • Precision finishes that boost durability & performance

  • Expertise across metals & plastics (e.g., anodizing Type II/III, chromate conversion, passivation, electropolish, zinc/nickel/EN plating, black oxide, powder coat/paint, bead-blast/brush/polish, SPI/VDI/Mold-Tech textures, laser/pad print)

  • Fast, efficient, high-quality delivery with RoHS/REACH documentation on request

As-machined

Parts come straight off the CNC—deburr and edge break only—leaving visible tool paths for a fast, cost-effective finish (typ. ~Ra 3.2 µm)

Smooth / Fine Machining

Optimized tooling, feeds, and coolant to reduce tool marks. Commonly ~Ra 1.6 µm; with fine passes, ~Ra 0.8 µm is often achievable. Lower Ra may require polishing or grinding.

Polishing

Multi-step mechanical finishing that reduces roughness and delivers a uniform high-gloss metal surface (often ~Ra 0.8–0.2 µm); may remove slight material, so mask critical fits.

Brushing

Abrasive belts/brushes create a unidirectional satin look. Pair with passivation or coating to improve corrosion resistance.

Bead Blasting

Uniform matte texture that softens tool marks. Suitable for aluminum, stainless steel, steel, brass (plastics case-by-case).

Anodizing (Aluminum)

An electrochemical oxide layer that boosts corrosion resistance and surface hardness, with optional dyed colors for cosmetic appeal.

Powder Coating

Electrostatically applied dry powder, then cured. Tough, color-rich finish with excellent wear and corrosion resistance. Thicker film—factor into tolerances.

Black Oxide (Steel)

Conversion layer that reduces glare and offers light corrosion protection; typically used with oil/wax topcoat.

Electroless Nickel Plating

Autocatalytic nickel deposit—very uniform thickness (great for complex shapes/bores), improves wear and corrosion performance and appearance.

Chem-Film / Alodine

Thin conversion coating that provides corrosion resistance, maintains electrical conductivity, and works as a paint base. Common colors: clear or gold.

Electroplating

(Zn / Ni / Cr, etc.) Enhanced corrosion protection, hardness, and cosmetics. Specify plating type, thickness, and appearance class; copper strike/activation may be used on certain substrates.

Passivation

Removes free iron to restore/enhance stainless corrosion resistance. Recommended after machining and blasting.

Mold & Part Finishes / Post-Processing

Mold Surface Standards

  • SPI A-1 ~ D-3 – From high-polish (diamond) to stone finishes.

  • VDI 3400 – EDM-based matte textures (fine → coarse).

  • Mold-Texture (Mold-Tech-style) – Patterns, grains, swirls (specify code or sample).

Part Finishing & Value-Adds

  • As-molded or bead-blast/brush, paint, dye (where applicable)

  • Laser marking / engraving, pad/silk printing, decals

  • Threaded insert installation (UN/metric), ultrasonic welding, solvent bonding

  • Light assembly and custom packaging/labeling to spec

  • Color: Pantone/RAL color-match; gloss/matte/satin

FAQs

Nearly any machined, molded, or 3D-printed part—from brackets and enclosures to medical, aerospace, and consumer components. We can minimize or remove handling marks and gate/flash remnants as required.

Yes—our engineers help select finishes, define masking plans, and validate cosmetics. You’ll get DFM guidance before we run parts.

Send your spec. We routinely source specialty coatings and can recommend equivalent processes if the exact spec isn’t available.

It depends on material + environment + cosmetics. Example: outdoor aluminum → Type II/III anodize or powder coat; stainless for sanitary/medical → electropolish; steel for paint base → phosphate. We’ll recommend options with pros/cons and samples.

Standard finishes are quick; specialty textures/platings take longer. We color-match Pantone/RAL and can share chips for approval.

RoHS/REACH statements available; material certs and CoC on request.
