II. Key Advantages
-
Hydraulic Efficiency: The precise 65° angle minimizes water impact and backflow pressure, increasing flow capacity by approximately 15-20% compared to standard sharp angles.
-
Anti-Clogging Design: The smooth, gradual curve allows leaves and small debris to pass through more easily, reducing maintenance frequency.
-
Versatile Application: Suitable for both pressure and non-pressure drainage systems in residential, commercial, and agricultural settings.

IV. Production Process
-
Raw Material Inspection: Only high-grade PVC resin with stabilizers and impact modifiers is used to ensure whiteness and toughness.
-
Injection Molding: Fully automated CNC injection molding machines ensure precise temperature control and consistent material distribution, eliminating internal stresses.
-
Precision Tooling: Molds are machined with high accuracy to guarantee the exact 65° geometry and smooth internal surfaces.
-
Cooling & Calibration: A multi-stage vacuum calibration system ensures perfect roundness and socket depth for leak-proof joints.
V. Quality Control
Every batch of Mo Ding 65° Diverter undergoes rigorous testing to meet international quality standards.
| Test Item | Standard & Procedure |
|---|---|
| Visual Inspection | 100% inspection for surface defects, bubbles, cracks, or discoloration. |
| Dimensional Check | Verification of socket diameter, wall thickness, and 65° angle using go/no-go gauges. |
| Drop Weight Impact | Samples are subjected to impact tests at 0°C or 23°C to ensure toughness (per ISO 3127). |
| Vicat Softening Temp | Tested to ensure heat resistance meets standard requirements (≥ 75°C typically). |
| Leak Tightness | Assembled systems are pressure-tested to verify joint integrity under hydraulic pressure. |
VI. Packaging & Logistics
-
Protective Packaging: Individual sockets are covered with dust-proof film. Products are packed in heavy-duty polypropylene bags or export-standard cartons with internal partitions to prevent transit damage.
-
Traceability: Each package is labeled with the Mo Ding logo, product specifications (e.g., “PVC-U 110mm 65° Elbow”), quantity, production date, and batch number for full traceability.
VII. Applications
-
Building Drainage: Used in soil and waste discharge systems (WCs, sinks) where a change in direction is required with minimal flow resistance.
-
Rainwater Harvesting: Connects horizontal gutters to vertical downspouts efficiently.
-
Ventilation Ducts: Suitable for low-pressure air or fume extraction systems due to its smooth bore.
-
Agricultural Drainage: For field drainage and irrigation pipeline networks.
