20,000 m² Heavy Precast Infrastructure Equipment Manufacturing Base
Established in 2011 in Qingzhou, Shandong Province, Heliyuan Heavy Machinery is a dedicated direct manufacturer of heavy-duty concrete pipe machines, precision steel molds, and infrastructure formwork systems exported to 45+ nations.
Factory Tooling & Quality Infrastructure
We invest in heavy machine tools, laser cutting lines, and heat treatment furnaces to guarantee structural integrity under extreme dynamic vibration.
20,000W Heavy Plate Fiber Laser Cutting
High-power laser systems ensure sub-millimeter seam accuracy for Q235B and Q345B heavy steel plates without micro-cracking or thermal distortion.
8-Meter Horizontal CNC Lathes
Heavy-duty extra-long lathe turning guarantees absolute coaxiality for suspension roller shafts and drive rings, keeping operational runout under 0.05mm.
600°C Thermal Stress-Relief Furnace
Every large pipe mold and machine chassis undergoes full-furnace electric heat treatment to eliminate 100% of residual welding stress, preventing long-term warping.
72-Hour Full-Load Continuous Testing
Before export dispatch, each concrete pipe machine runs unbroken for 72 hours under mechanical load with vibration frequency and bearing thermal logging.
Schedule a Guided Qingzhou Heavy Machinery Factory Tour
We warmly invite municipal contractors, precast plant owners, and civil engineering delegations worldwide to inspect our production lines, witness 72h live trial runs, and examine raw steel certifications in person.
