Tie Plate production process

Raw material preparation
Material selection: Select high-strength, wear-resistant, corrosion-resistant materials as raw materials, such as cast steel, cast iron or special alloys.
Inspection: Quality inspection of raw materials to ensure that they meet production requirements.
Cutting and cutting
Cutting: According to the design drawings and specifications, the use of standard tools or machine equipment to cut raw materials.
Cutting: Using sawing machine, shearing machine and other equipment to precisely cut raw materials to ensure the dimensional accuracy of the plate.
Forming and processing
Forming: The cutting raw materials are processed into the preliminary shape of the pad by bending, stamping and other processes.
Processing: Further processing of the preliminary formed pad, such as punching, grooving, etc., to meet specific design requirements.
Welding and assembly
Welding: If necessary, the various parts of the pad are welded to ensure its structural integrity and stability.
Assembly: The welded pad is assembled with other track structure components (such as fasteners, bolts, etc.) for subsequent testing and inspection.
Surface treatment and protection
Grinding: Use a polishing machine or grinding wheel and other equipment to polish the plate to remove burrs and dirt on the surface.
Rust removal: The use of appropriate rust removal methods (such as sandblasting, pickling, etc.) to remove the rust and oxide layer on the surface of the plate.
Spraying: Surface treatment such as electrostatic spraying or hot dip galvanizing is carried out on the gasket to improve its weather resistance and service life.
Inspection and testing
Quality inspection: Quality inspection of the produced pad, including dimensional accuracy, mechanical properties, weather resistance and other aspects of the test.
Performance testing: Gravity tests or other performance tests are performed on the pads to ensure that they can withstand train loads and meet design requirements.
