Rigid/Unplasticized PVC
Rigid or unplasticized PVC (uPVC) is a type of PVC that does not contain plasticizers, making it stiffer and more durable than flexible variants. It is commonly used in construction materials like window frames and pipes due to its strength and resistance to environmental factors.
Rigid/Unplasticized PVC Properties
| Property | Value |
|---|---|
| Density | 1.4 g/cm³ |
| Tensile Strength | 50-70 MPa |
| Flexural Modulus | 2,400-3,000 MPa |
| Impact Resistance | High |
| Chemical Resistance | Excellent |
| Thermal Conductivity | 0.14 W/m·K |
| UV Resistance | Good |
| Insulating Properties | Good |
PVC Finishes
Achieving the right surface finish is crucial in the machining process. Various finishing techniques can be applied to machined PVC parts to improve their appearance and functionality. Common finishes include sanding, polishing, and coating with UV-resistant materials. These techniques not only improve aesthetics but also contribute to the durability of the final product.
Design Guidelines: How to Save Money When You Machine PVC
- Simplify Designs: Avoid overly complex shapes that require extensive machining time.
- Optimize Tool Paths: Efficient tool paths minimize machining time and wear on cutting tools.
- Select Standard Sizes: Use standard sizes for sheets and components to reduce waste.
- Choose the Right Thickness: Design parts with appropriate thickness to balance strength and material usage.
Implementing these strategies can lead to significant savings in both time and material costs during the machining process.
Benefits of Machining PVC
- Versatility: PVC can be machined into a wide variety of shapes and sizes, making it suitable for numerous applications across different industries.
- Durability: Machined PVC parts are resistant to corrosion, chemicals, and UV light, ensuring long-lasting performance.
- Cost-Effectiveness: Compared to metals and other materials, PVC is often more affordable to machine, reducing overall production costs.
- Excellent Mechanical Properties: With high impact resistance and tensile strength, machined PVC components can withstand significant stress and strain.
- Insulating Properties: PVC provides good electrical insulation, making it ideal for electrical applications.
Disadvantages of Machining PVC
- Heat Sensitivity: During machining, excessive heat can cause the material to warp or melt if not managed properly.
- Limited High-Temperature Resistance: While durable at room temperature, PVC may degrade at elevated temperatures.
- Surface Finish Challenges: Achieving a high-quality surface finish can require additional processing steps due to the nature of the material.
- Environmental Concerns: Although PVC is one of the greenest plastics available, its production and disposal can raise environmental issues that need consideration.

FAQs on Machining PVC | PVC Cutting Techniques, Precision Machining
Plastic machining techniques like milling, turning, and drilling are well-suited for engineering plastics due to their adaptability. CNC machining PVC and other polymers are effective when the material properties are considered, such as thermal expansion and machinability. Using the right coolant and material selection is crucial to produce high-quality plastic parts and components.
Machining PVC plastic is generally safe when proper precautions are taken, such as using appropriate coolants to manage heat and guide to PVC-specific methods. We recommend focusing on the properties of PVC to avoid overheating or deformation and achieve the best PVC machinability. Plasticized PVC requires careful handling to maintain its structural integrity during plastic machining.
PVC’s health risks arise mainly from improper handling, as machining PVC can release harmful fumes if overheated. Understanding the material properties and following a guide to PVC ensures safe practices. For optimal safety, avoid machining processes that compromise the machinability of PVC plastic or the surrounding environment.
