UPVC Floor Drain Pipe Fitting Mould: Technical Overview UPVC (Unplasticized Polyvinyl Chloride) floor drain pipe fitting moulds are specialized tools used in the injection moulding process to manufacture precise and durable drainage components for plumbing systems. These moulds are designed to produce fittings that ensure efficient water flow, leak-proof connections, and long-term performance in residential, commercial, and industrial applications. 1. Material and Design The moulds are typically made from high-grade steel (e.g., P20, H13, or stainless steel) to withstand high-pressure injection cycles and resist wear. Key design considerations include: - Cavity and Core: Precision-machined to create the internal and external geometries of the fitting, ensuring tight tolerances (e.g., ±0.02mm). - Cooling System: Integrated channels for efficient heat dissipation to reduce cycle time and prevent warping. - Ejection Mechanism: Smooth ejection of the finished part to avoid deformation. - Venting: Proper venting to eliminate air traps and ensure defect-free surfaces. 2. Key Features of the Produced Fittings The moulds manufacture UPVC floor drain fittings with the following characteristics: - Corrosion Resistance: UPVC is inherently resistant to chemicals, moisture, and microbial growth. - Smooth Interior: Minimizes friction to enhance drainage efficiency. - Standard Compliance: Meets international standards (e.g., ISO 3633, ASTM D2665) for dimensions and pressure ratings. - Modularity: Compatible with various pipe diameters (e.g., 50mm, 75mm, 110mm) and configurations (elbows, tees, couplings). 3. Manufacturing Process 1. Material Preparation: UPVC granules are dried and fed into the injection moulding machine. 2. Injection: Molten UPVC is injected into the mould cavity under high pressure (800–1,500 bar). 3. Cooling & Ejection: The part solidifies, and ejector pins release it from the mould. 4. Post-Processing: Flash removal, deburring, and quality checks (dimensional, pressure, and leak tests). 4. Applications UPVC floor drain fittings are widely used in: - Building Drainage Systems: Bathrooms, kitchens, and balconies. - Sewage Networks: Underground and vertical piping. - Stormwater Management: Roof and surface water drainage. 5. Advantages of UPVC Moulds - Durability: Steel moulds support high-volume production (100,000+ cycles). - Cost-Effectiveness: Low maintenance and long service life reduce per-unit costs. - Customization: Moulds can be tailored for specific fitting designs or regional standards. Conclusion UPVC floor drain pipe fitting moulds are critical for producing reliable, standardized drainage components. Their precision engineering ensures consistent quality, while UPVC’s material properties guarantee longevity and performance in diverse environments. The moulds’ efficiency and adaptability make them indispensable in modern plumbing infrastructure.
