CNC Machining for Polystyrene (PS) Parts
We’ve been machining polystyrene (PS) for years, making everything from prototypes to custom parts for real projects. PS can be tricky—thin walls, delicate features, and complex shapes—but we know how to handle it. With the right tools and careful CNC setups, every part comes out clean, accurate, and ready to use.
Our CNC PS parts go into electronics (like housings and insulation mounts), display and signage (transparent panels and fixtures), consumer goods (lightweight structural pieces), and educational models. From the first design optimization to the finished part, we make sure everything works as expected and stays on budget.

| Tensile Strength, Yield (MPa) | Elongation at Break | Hardness | Impact Strength | Heat Deflection | Heat Deflection Temperature | Melting Point |
|---|---|---|---|---|---|---|
| 35–55 MPa | 1–3% | R110–R120 | 10–30 J/m | 90–100°C | 80–90°C | No true melting point; softens at about100°C |

Surface Finishing Options for Polystyrene CNC Parts
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.
