Finishing processes

Our most commonly performed finishing processes are below.

Please note that we only perform finishing on Penta-machined parts as part of our one-stop-shop service. 

Bead Blasting

Bead blasting uses fine glass or ceramic beads to create a smooth, uniform, matte surface finish on machined parts. It reduces tool marks and improves appearance without affecting part dimensions.

Brushing

Brushing gives components a directional, satin finish by running abrasive brushes over the surface. This is often used for decorative appeal while also removing small burrs or imperfections.

Plating

Plating deposits a thin layer of metal—such as nickel, zinc, or chrome—onto the part surface. It enhances corrosion resistance, wear resistance, and overall durability.

Polishing

Polishing refines the surface of a part to achieve a bright, reflective finish. This process not only improves aesthetics but can also reduce friction in functional applications.

Powder coating

Powder coating applies a dry powder that is cured under heat to form a durable, protective layer. It provides excellent resistance to wear, corrosion, and chemicals, available in a wide range of colours.

Ultrasonic cleaning

Ultrasonic cleaning uses high-frequency sound waves in a cleaning solution to remove fine particles, oil, and machining residue. It ensures components are free from contamination before use or further finishing.
