Surface Finishing Options for CNC Machined HDPE Parts

To improve the appearance and performance of your CNC machined HDPE components, we offer a variety of surface finishing services. Whether you need a clean matte surface, enhanced aesthetics, or functional part labeling, our finishing options ensure your HDPE machining parts meet both visual and application needs.

Standard finish with visible tool marks; suitable for functional prototypes and internal components.

Uses abrasive media to create a uniform matte or satin finish; also improves coating adhesion on plastic or metal surfaces.

Adds logos, text, or identification marks via silk screen or pad printing, ideal for branding or part tracking.

Removes machining marks and evens out surface texture; ideal for prototypes and parts where appearance is not critical.

Painting and powder coating provide colorful, durable, and corrosion-resistant finishes.

Deposits metal layers such as nickel or chrome on parts, improving wear resistance, conductivity, and aesthetic quality.

Produces a smooth, glossy finish; commonly applied to plastics like PC or PMMA for enhanced clarity and premium look.

Chemical treatment for ferrous metals, creating a dark, corrosion-resistant surface with minimal thickness.

Electrochemical process for aluminum that enhances corrosion and wear resistance, with options for colored finishes.

Yes. HDPE machining is easy, low-cost, and yields tough, chemically resistant parts—great for structural, outdoor, and fluid-related uses.
HDPE can tolerate moderate heat but is not ideal for high-temp environments. For better thermal resistance, consider materials like PTFE or PEEK.
HDPE is widely used in water treatment systems, food processing equipment, medical trays, packaging machinery, and electronics housings.
CNC machining HDPE offers smoother finishes, tighter tolerances, and stronger parts than 3D printing, especially for load-bearing or functional components.
Yes. Our team has extensive experience milling HDPE with tight tolerances. We'll optimize your design for best performance and manufacturability.
While rough estimates are possible, accurate pricing for plastic CNC machining needs a CAD or technical drawing.
