Manufacturing Process

We follow a precision-controlled casting process to ensure dimensional accuracy, high strength, and long-term reliability for railway applications:

  • High-Precision Molding: Ensures uniform cavity shapes and consistent quality for heavy-duty components.

  • Controlled Pouring: Minimizes shrinkage, porosity, and turbulence defects for structural integrity.

  • Heat Treatment: Enhances hardness, grain structure, and mechanical properties to withstand high loads.

  • CNC Machining: Delivers tight tolerances and smooth surfaces for precise fitting and performance.

  • Final Inspection: Dimensional and visual checks to ensure zero-defect output and dependable railway operation.

Testing & Compliance

We adhere to strict quality protocols to ensure every railway casting meets international safety and performance standards:

  • Hydrostatic Testing: Validates pressure integrity under operational loads.

  • Air Leak Testing: Ensures no internal porosity or gas escape.

  • Dye Penetrant Testing (DP): Detects surface cracks or defects.

  • Dimensional Inspection: Confirms components meet precise design tolerances.

  • Mechanical Property Checks: Verifies hardness, tensile strength, impact resistance, and durability for reliable railway operation.
