CNC Machining & 3D Printing of Sandblasting / Polishing / Anodizing / Painting / Electroplating

Equipment & Process Scope

• Sandblasting equipment (for texture/matte effects)

• Vibratory polishing machines (for smooth surfaces)

• Anodizing lines (Type II & III, for corrosion protection)

• Powder/wet painting booths (custom color application)

• Electroplating tanks (nickel, chrome, zinc coatings)

Surface Quality & Tolerance

• Surface roughness control: Down to Ra 0.2 μm

Lead Time & Batch Flexibility

• Typical lead time: 5–12 business days (varies by finish type & batch size)

• Batch range: Single prototypes to mass production (consistent quality guaranteed)

Supported Metals

• Aluminum (ideal for anodizing, polishing)

• Stainless Steel (suitable for passivation, electroplating, sandblasting)

• Brass/Copper (excellent for polishing, electroplating)

• Titanium (compatible with anodizing, chemical passivation)

Finish Type Details

• Sandblasting: Creates matte/textured surfaces (hides minor imperfections)

• Polishing: Offers mirror, satin, or semi-gloss finishes (enhances aesthetics)

• Anodizing: Color-customizable (Type II/III) with corrosion resistance (aluminum-exclusive)

• Painting: Powder coating (durable) or wet spray (high color accuracy) in custom shades

• Electroplating: Nickel (wear-resistant), chrome (decorative), zinc (rust-proof) coatings

Q1: What finishing services do you offer for CNC and 3D printed parts?

A1: We provide a full suite of services including sandblasting, polishing, anodizing (aluminum), painting (powder/wet), and electroplating (nickel/chrome/zinc) for CNC machined metals and compatible 3D printed parts.

Q2: Can you provide color anodizing and custom painting?

A2: Yes. Anodizing offers a broad spectrum of custom colors (via Type II/III processes for aluminum), and painting includes both powder coating and wet spray in client-specified shades (Pantone/RGB matching available).

Q3: What is the typical lead time for these surface finishes?

A3: Lead times range from 5 to 12 business days, depending on the finish complexity (e.g., simple sandblasting vs. multi-step electroplating) and order batch size (prototypes vs. mass production).

Q4: Are your finishing processes compliant with industry standards?

A4: Yes. All our finishing processes meet international standards including ISO (quality management) and RoHS (environmental safety), with additional compliance for sector-specific requirements (e.g., medical device biocompatibility).

Q5: Do you support prototype and mass production finishing?

A5: Absolutely. We handle all batch sizes—from single prototypes (for design validation) to large-volume mass production—with consistent quality control to ensure every part meets the same finish standards.
