DWV Return Bend PVC 180 Degree Elbow Mold

This elbow mold is designed with a total of 4 hydraulic cylinders to provide power for the 3-step elbow ejection process. Its basic structure is shown in the figure below:

As shown in the video. The ejection process of this PVC 180 Degree Elbow Mold is divided into 3 steps.

Step 1: The hydraulic cylinder on the upper side of the movable mold pulls out the core block of the elbow

Step 2: The hydraulic cylinders on both sides of the movable mold pull the ejector plate to eject the core, elbow and rotating arm together

Step 3: The hydraulic cylinder on the rear side of the fixed mold drives the linear gear to rotate, and the swing arm rotates accordingly. Then the rotating arm moves the product out and separates it from the mold core.

Precision Engineering

Our return bend molds are crafted with cutting-edge CNC machining technology, ensuring exact dimensions and smooth finishes for PVC 180 degree elbows. This eliminates leaks and guarantees seamless integration into DWV systems.

Durabilité & Longevity

Constructed from high-grade steel with advanced heat treatment, our pvc 180 degree elbow molds withstand high-pressure injection cycles, reducing downtime and maintenance costs.

Versatile Design

Compatible with all standard PVC materials, our molds produce return elbows that meet ASTM, ISO, and NSF certifications, ideal for plumbing, HVAC, and industrial applications.

Cost-Efficiency

Optimized cooling systems and multi-cavity options maximize production output, lowering per-unit costs for high-volume orders.

The core value of the DWV PVC 180-degree return elbow lies in its U-shaped structural design, which can accurately achieve a 180-degree reversal of the pipe direction. This feature allows it to store a certain amount of liquid in the pipe, prevent sewer gas backflow, and ensure indoor air quality. In basements, equipment mezzanines or narrow pipe shafts, return elbows can replace multiple short-radius elbows, reduce connection points, and reduce the risk of leakage.

Residential Construction: Perfect for sewage lines, basement drainage, and kitchen/bathroom plumbing.

Commercial Projects: Supports large-scale HVAC systems and waste management in malls, offices, and hospitals.

Agricultural Use: Durable return elbows for irrigation channels and livestock water systems.
