Manufacturing Capability
Production Equipment
Industry-leading machinery behind every Puhui pipe
Overview
Built around proven machinery
Puhui's daily output of HDPE and PVC pipe systems rests on three categories of production equipment: continuous extrusion lines for pipe, injection molding presses for fittings, and fusion stations for fabricated assemblies.
Every line is paired with in-line gauges and sampling-based testing so our QA team can monitor dimensions, wall thickness, and surface consistency before products move to packing and shipment.
Core Systems
Key Equipment Families
Four coordinated systems run from raw material into verified pipe solutions.
HDPE Extrusion
Large-scale extrusion lines support stable HDPE pipe output from smaller service diameters to heavy-wall production.
Injection Molding
Fittings production supports complete system supply and helps keep pipe-to-fitting compatibility under one source.
Fusion Welding
Butt fusion and electrofusion stations back in-house fabrication and assembly work for custom connections.
QA Test Rigs
Inspection and pressure-testing equipment helps confirm production consistency before products leave the factory.
Process Control
Measured while it is made
Laser diameter gauges, wall-thickness references, and continuity sampling track every critical dimension as the pipe moves through the line. That discipline reduces variation and keeps downstream packing more predictable.
- Continuous dimensional monitoring
- In-line defect observation
- Sampling linked directly to QA
