Custom Moulded PVC Product
If PVC is the right material for your application, send us your drawings or samples to us. We'll deliver durable, injection moulded PVC parts to your exact specifications.
Custom PVC Injection Molding Solution
Zhongren specializes in custom moulded PVC solutions for applications that require durability, flame resistance, and chemical stability. Our expertise in PVC injection molding allows us to produce high-precision parts using both rigid and flexible PVC formulations. Injection moulded PVC is a trusted solution for challenging environments where other plastics may degrade, warp, or fail.
How Are PVC Parts Manufactured?
We utilize a range of advanced PVC plastic moulding and fabrication technologies to meet customer specifications:
- PVC Injection Moulding
- PVC Extrusion Moulding
- PVC Compression Molding
- PVC Overmolding
- Insert Molding with PVC
- PVC CNC Machining
Due to PVC’s thermal sensitivity and corrosive behavior during processing, proper temperature control and corrosion-resistant tooling are essential for optimal results.
Common Applications of Moulded PVC
Injection moulded PVC is ideal for:
- Electrical enclosures and insulation components
- Medical tubing and connectors
- Industrial seals and fittings
- Consumer products and protective cases
- Cable grommets and wire management parts
- Flame-retardant housings
Our Valued-Added Services
- Design and Engineering Support
- Material Testing and Certification
- Surface Finishing and Printing
- Assembly and Sub-Assembly
- Custom Packaging and Labeling
Advantages of PVC Injection Molding
- Excellent flame resistance and chemical stability
- Cost-effective for high-volume production
- Supports both rigid and flexible formulations
- Strong electrical insulation properties
- UV-resistant and weatherable grades available
Disadvantages of PVC Molding
- Thermal degradation if not processed correctly
- Requires corrosion-resistant molds and vents
- Limited temperature tolerance (< 60–80°C for flexible PVC)
- Less impact-resistant than some engineering plastics
FAQ of PVC Injection Molding
Is PVC suitable for injection molding precision parts?
Yes. Both rigid and flexible PVC plastic molding can achieve tight tolerances and consistent surface finishes, especially when using proper mold materials and temperature profiles.
What are common challenges in moulded PVC processing?
PVC is heat-sensitive and releases corrosive gases if overheated. Proper tooling, venting, and temperature control are essential to avoid degradation, burning, or porosity.
Can PVC be used in overmolding or insert molding applications?
Yes, especially flexible PVC. However, material compatibility and adhesion to substrates must be carefully considered during PVC overmolding or insert molding.
Do you offer food-grade or medical-grade PVC options?
Yes. We supply certified medical-grade and FDA-compliant injection moulded PVC parts for diagnostic, tubing, and packaging applications.
What’s the lead time for custom PVC molding?
Typical lead time for PVC injection moulding tooling is 2–4 weeks. Production starts after tool validation and depends on part complexity and batch size.
How does moulded PVC compare to other thermoplastics?
Moulded PVC offers excellent flame retardancy and chemical resistance but is not ideal for high-heat or high-impact use. Compared to polyethylene or ABS, it provides better insulation and rigidity for specific use cases.
