Release Time: 2025-10-16
For any concrete plant, the mixing arm is the heart of uniform, efficient batching. Ma’anshan Haitian Heavy Industry Technology Development Co., Ltd. (Haitian Casting) leverages years of expertise in wear-resistant castings and intelligent manufacturing to deliver premium ZG310-450 mixing arms trusted by leading domestic and international equipment manufacturers.


ZG310-450 Material: Superior Wear Resistance and Longevity

Haitian Casting selects ZG310-450 high-chromium alloy cast iron and applies precision quenching and tempering. This yields:

  • Exceptional hardness: Achieving HRC 57–62 for outstanding surface wear resistance.

  • High toughness: Tempering eliminates stresses to ensure dense internal structure and excellent impact performance.

  • Extended service life: Exceeds 13,000 operating hours under standard batching conditions, dramatically reducing maintenance downtime.


Precision Design and Smart Manufacturing

Haitian’s advanced production technologies guarantee consistent quality and rapid delivery:

  1. DISA Automated Casting Line A Danish DISA vertical molding line with integrated core-setting ensures dimensional accuracy up to CT8 tolerance.

  2. MES Digital Production Management Real-time tracking of pouring temperatures and heat-treatment curves optimizes scheduling and shortens lead times.

  3. Robotic Finishing and CMM Inspection Robotic grinding followed by manual touch-up, then full-size verification by 3-axis coordinate measuring machines holds assembly interfaces within 1.5–3 mm.


Rigorous Quality Control: 100% Inspected

  • Chemical analysis: Spectrometer testing on every melt to maintain stable Cr, C, Mn composition.

  • Mechanical testing: Hardness, tensile, and impact tests meet or exceed national standards.

  • Dimensional checks: First article and trial mold parts undergo complete inspection; in-process samples are checked daily.
