CNC Machining in Polystyrene Material

At Jiangzhi, we specialize in polystyrene CNC machining service using advanced PS CNC equipment. Whether you’re working on functional prototypes or custom PS parts for end-use applications, our team ensures each CNC polystyrene component is dimensionally stable, cleanly cut, and ready to perform. With deep experience in machining polystyrene, we can produce complex geometries, thin walls, and detailed internal features efficiently.

Common PS CNC parts applications include: Electronics (housings, insulation mounts). Display and signage (transparent panels, fixtures), Consumer goods (lightweight structural parts), Education and modeling (prototype structures, academic models). From design to delivery, Jiangzhi ensures your polystyrene machined parts meet both technical and budget expectations.

PS Machining Plastic Properties

Polystyrene (PS) CNC machining is valued for its clean machinability, dimensional stability, and affordability. While more brittle than some engineering plastics, PS performs well under the right fixturing and delivers reliable results for precise, lightweight components. Available in both clear (GPPS) and impact-resistant (HIPS) forms, it’s a versatile material with strong insulating properties and low water absorption—ideal for cost-effective, visually appealing parts.
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

Advantages & Disadvantages of PS CNC Machining

When considering PS CNC machining for your project, it’s important to weigh both the advantages and limitations. Understanding these characteristics helps determine if CNC polystyrene is the right fit for your application.

Surface Finishing Options for Polystyrene CNC Parts

To enhance the appearance and performance of your CNC machined polystyrene components, we provide a range of surface finishing options. Whether you require a clean finish, improved aesthetics, or custom labeling, our services ensure your CNC PS parts meet both visual and functional expectations.

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, PS machining is effective for lightweight, low-cost parts with good dimensional accuracy.

GPPS offers better clarity, while HIPS adds impact resistance. We machine both based on your needs.

Yes, with proper fixturing, we can produce intricate details and thin features in polystyrene.

Yes. We follow strict safety and ventilation protocols, especially when machining high-speed.

Absolutely. Our engineers offer DFM (Design for Machining) feedback to help optimize your part.
