PVC in CNC Machining
Polyvinyl Chloride (PVC) is widely used in CNC machining due to its excellent mechanical properties, chemical resistance, and affordability. PVC’s durability and ease of machining make it suitable for various industries. Its high strength-to-weight ratio, low moisture absorption, and resistance to environmental degradation make it an ideal material for producing custom CNC machined parts. PVC is available in various grades, with PVC Grey being a popular choice for many applications due to its balanced properties and consistent performance.

Surface Finishing Options for PVC
RapidDirect provides a wide range of surface finishing options for PVC, enhancing your components’ aesthetic and functional properties. Our variety of finishing techniques ensures that your PVC machined parts meet the specific requirements of your application.
As machined
PVC parts often come out of machining with a smooth, clean finish that’s good to go without extra work.
Sand Blasting
A light sand blast can give PVC a nice matte look, perfect for a uniform, non-reflective surface—just keep it gentle to avoid wear.
Teflon Coating
Adding a Teflon layer gives PVC low-friction, non-stick properties, which is great for parts that slide or handle wear.
Painting
PVC takes well to paint with the right prep, making it easy to add color or a protective layer where needed.
Powder Coating
Though not as common, powder coating can add a durable, attractive finish if the PVC surface is carefully prepared.
Pros and Cons of
PVC CNC Machining
PVC CNC machining offers a range of benefits and some limitations, making it essential to understand these aspects when planning your project.
