Plastic Pipe Elbow Injection Mold

This injection mold is designed for producing plastic pipe elbows, commonly used as water pipe connectors in plumbing, irrigation, and industrial piping systems. The mold is typically made from high-quality mold steel 718H. For high-volume production, hardened steel such as H13 with nitriding treatment is often used to extend mold life.

The mold is a horizontal, two-plate injection mold with a lifter mechanism to form the elbow's curved inner channel.

Typical equipment parameters include a clamping force of 80 tons, injection pressure of 80–150 MPa, and mold temperature control between 40–60°C, as we use PP. The mold produces a 50 mm elbow.

Application scenarios include residential water supply systems, drainage networks, agricultural irrigation, and industrial fluid transportation, where reliable, leak-free plastic elbow connections are essential.
