Cosmetic finishes

Surface finishes can serve either a functional or aesthetic purpose. Surface finishes that serve both purposes are deemed cosmetic finishes, and are used for cosmetic parts. Producing cosmetic parts requires additional measures to minimize defects such as hang marks and scratches from tools.

Non-cosmetic

Primary machining marks will still be visible

As machined
Smooth machining
Fine machining
Electroless Nickel Plating
Anodized type III (Hardcoat)
Black oxide

Cosmetic on request

Finishes can be either cosmetic or non-cosmetic as per request

Brushed + Anodizing type II
Bead Blasted + Anodizing type II
Bead Blasted
Brushed
Nano coating

Cosmetic by default

These finishes will always serve a cosmetic function

Brushed + Electropolished
Polishing

Below are a small selection of the CNC machined parts and end-use components we produce for our customers.

Medical stainless steel parts

Features: corrosion resistance, high temperature resistance, high strength. Applications: Medical equipment, chemical containers, etc.

Drone fixed bracket parts

Drones need to minimize weight as much as possible to enhance flight efficiency, and aluminum alloy, with its low density but high strength, makes it an ideal material for fixed rotor supports.

Drone bracket parts

Drones need to minimize weight as much as possible to improve flight efficiency, and aluminum alloy, with its low density but high strength, makes it an ideal material for brackets.

Drone propeller bracket parts

The wings and rotors of drones are crucial components for generating lift and maintaining flight attitude. Aluminum alloy, due to its high strength and lightweight properties, is often used to manufacture these components.

Action camera rabbit cage parts

The low density of aluminum alloy results in an overall lightweight design for the phone cage, making it easy to carry and use for extended periods without causing excessive strain for photographers.

Intelligent robot parts

The application of aluminum alloy in robotic joints is extensive, primarily benefiting from its lightweight nature, high strength, wear resistance, and excellent processing properties.

Material Suitability

This involves choosing metallic materials that are suitable based on processing needs and product usage. For instance, aluminum alloy may be a good choice for products that require high corrosion resistance and aesthetics, but attention should be paid to its processing characteristics and potential surface issues.
