Sand Casting Railway Parts

Product Overview

We produce railway components using advanced coated sand casting technology, combining material excellence and engineering precision:

--Materials: High-strength cast steel, ductile iron (e.g., QT450-10, QT500-7), and alloy steels compliant with international railway standards (e.g., EN, ASTM).

--Process: Coated sand casting ensures dimensional accuracy (CT8-CT9), smooth surface finishes, and complex geometries with minimal post-casting machining.

--Welding Certification: Certified welding processes (e.g., ISO 3834, EN 15085) for component assembly and repair, ensuring structural integrity.

Key Product Categories

1.Bogie Components: Side frames, bolsters, axle boxes, and brake beams.

2.Coupling Systems: Draft gears, coupler bodies, and yoke castings.

3.Track and Infrastructure Parts: Rail brackets, sleepers (ties) inserts, and switch components.

4.Braking Systems: Brake discs, caliper housings, and valve bodies.

5.Customized Solutions: Prototype development and OEM-specific designs.

Quality Control

Material Testing:

--Spectrochemical analysis to verify material composition.

--Mechanical properties testing (tensile strength, impact toughness).

Dimensional Inspection:

--CMM (Coordinate Measuring Machine) for critical dimensions.

--Compliance with ISO 8062 (CT8-CT9 tolerances).

Non-Destructive Testing (NDT):

--Magnetic particle inspection (MPI) for surface defects.

--Ultrasonic testing (UT) for internal integrity.

Welding Quality:

--Certified welders and procedures (EN 15085/ISO 3834).

--Weld seam inspection via X-ray or dye penetrant testing.

Performance Validation:

--Fatigue testing.

--Salt spray testing for corrosion resistance.
