UPVC Tee Pipe Fitting Mould: Design, Functionality, and Manufacturing Process A UPVC tee pipe fitting mould is a precision tool used to manufacture three-way pipe connectors, essential for branching fluid or gas flow in plumbing, irrigation, and industrial piping systems. These moulds are designed to produce durable, leak-proof fittings that meet industry standards for pressure resistance, chemical stability, and dimensional accuracy. 1. Design and Structure The mould consists of two primary components: the core and cavity. The cavity forms the outer shape of the tee fitting, while the core creates the internal bore. High-grade tool steel (e.g., P20, H13) is commonly used for its wear resistance and ability to withstand high injection pressures. The mould includes cooling channels to regulate temperature, ensuring uniform cooling and minimizing warping. Ejector pins facilitate the removal of the finished part without damage. 2. Key Features - Precision Machining: CNC milling and EDM (electrical discharge machining) ensure tight tolerances (±0.05mm) for smooth sealing surfaces. - Ventilation System: Small vents prevent air traps, reducing defects like burns or incomplete fills. - Corrosion Resistance: Chrome plating or nitriding extends mould life by preventing degradation from UPVC’s acidic byproducts during injection. 3. Manufacturing Process 1. Material Preparation: UPVC granules are dried to remove moisture. 2. Injection Molding: Molten UPVC is injected into the mould at 160–200°C under high pressure (800–1,500 bar). 3. Cooling & Ejection: The mould cools rapidly (~20–40 seconds), and ejector pins release the solidified tee fitting. 4. Post-Processing: Flash removal and deburring ensure smooth edges. 4. Quality Control Finished fittings undergo tests for: - Dimensional Accuracy: Verified with calipers and CMM (coordinate measuring machines). - Pressure Resistance: Hydrostatic testing confirms leak-proof performance. - Visual Inspection: Checks for surface defects like sink marks or flow lines. 5. Applications UPVC tee fittings are widely used in: - Potable water systems (due to non-toxicity). - Drainage networks (resistant to chemicals and abrasion). - Industrial pipelines (handling acids, alkalis, or wastewater). Conclusion A well-designed UPVC tee pipe fitting mould ensures high production efficiency, consistent quality, and long service life. Its precision engineering directly impacts the performance of the final product, making it critical for manufacturers to invest in advanced mould technology and maintenance.
