U-PVC Tee with Door Pipe Fitting Mould: Description and Applications A U-PVC Tee with Door pipe fitting mould is a specialized tool used in the manufacturing of U-PVC (unplasticized polyvinyl chloride) tee fittings that incorporate an inspection or cleaning access point, commonly referred to as a "door." These fittings are widely used in plumbing, drainage, and irrigation systems due to their durability, corrosion resistance, and ease of installation. Design and Features 1. Material & Construction - The mould is typically made from high-grade steel or alloy to withstand high-pressure injection moulding processes. - Precision machining ensures smooth surfaces and accurate dimensions for consistent production of U-PVC tee fittings. 2. Tee Configuration - The mould produces a three-way (T-shaped) fitting with equal or reducing branches, allowing for fluid flow diversion in piping systems. - The "door" feature is an integrated removable panel or access point, enabling easy inspection, cleaning, or maintenance without disassembling the entire pipeline. 3. Mould Components - Core & Cavity: Forms the internal and external shapes of the tee fitting. - Ejection System: Ensures smooth removal of the finished part from the mould. - Cooling Channels: Maintain optimal temperature for efficient production cycles. Manufacturing Process 1. Injection Moulding - U-PVC resin is melted and injected into the mould under high pressure. - The mould is clamped shut until the material solidifies into the desired tee shape. 2. Demoulding & Finishing - After cooling, the mould opens, and the fitting is ejected. - Any excess material (flash) is trimmed, and the door mechanism is tested for functionality. Applications - Plumbing Systems: Used in residential and commercial drainage networks. - Sewage & Wastewater Systems: Allows easy access for blockage removal. - Industrial Pipelines: Suitable for chemical and water treatment plants due to U-PVC’s corrosion resistance. Advantages - Durability: U-PVC fittings resist chemicals, UV rays, and abrasion. - Leak-Proof Design: Precision moulding ensures tight seals. - Low Maintenance: The door feature simplifies inspections without pipe disassembly. Conclusion The U-PVC Tee with Door pipe fitting mould is essential for producing high-quality, functional fittings that enhance piping system efficiency. Its robust design, ease of maintenance, and versatility make it a preferred choice in modern plumbing and industrial applications. (Word count: ~500)
