PS in CNC Machining
Polystyrene (PS) is a versatile thermoplastic known for its ease of machining, making it a popular choice in various industries. Its unique properties, such as excellent dimensional stability, low moisture absorption, and good electrical insulation, make it ideal for various CNC machining applications. PS is especially valued for its ability to be molded into complex shapes with fine detail, allowing for the creation of precise components. The material’s cost-effectiveness and availability in transparent forms further enhance its utility, enabling the production of clear parts where visibility is required.

As machined
S surfaces are often smooth and ready to use directly from machining, suitable for many applications without extra finishing.
Sand Blasting
Light sand blasting can add a subtle matte texture to PS, though it’s best applied carefully to avoid compromising the material’s brittleness.
Painting
Painting works well on PS with proper surface preparation, making it a good choice for adding color or protective layers.
