Elastic Rail Clips

Receipt of Purchase Order

Upon receiving the purchase order, it is reviewed and analysed to ensure alignment with project requirements.

Material Management

Drawings are thoroughly reviewed and cross-checked for any discrepancies, which are resolved with client approval. The Bill of Materials (BOM) is then prepared to initiate the procurement process.

Raw Material Procurement

Raw materials are procured based on indent records, ensuring adherence to required specifications and quality standards.

Raw Material Inspection

Raw materials are inspected at the supplier's premises by RITES. Upon receipt, they undergo further in-house quality checks to validate compliance with standards.

Production Planning

Job cards are generated to outline the production schedule and allocate resources efficiently.

Fabrication Process

Our fabrication process includes several operations:

• Cutting: Performed using hydraulic shearing machines or oxy-fuel cutting to achieve precise results.
• Punching: Utilises a punch press to create holes via shearing.
• Drilling: A rotary cutting process to bore holes in solid materials.
• Stamping: Sheet-metal forming process that involves punching, embossing, and coining.
• Fitting: Joining multiple materials of different sections and sizes.
• Welding: A high-temperature process to fuse metals, forming strong joints.
• Finishing: Removing weld spatters, grinding rough edges, and completing the materials in their black stage.

In-process Inspection

Throughout the fabrication process, operations such as cutting, punching, drilling, stamping, fitting, and welding are inspected to ensure quality.

Mass Production

Once the initial phases pass inspection, mass production begins to meet project demands.

Surface Treatment

The transition from raw to finished products involves the following surface treatment steps:

• Pickling in Caustic Soda Solution: Removes impurities and scales from the surface.
• Rinsing in Water House: Removes residual caustic solution.
• Pickling in Acid Tank: Further cleaning and preparation for galvanization.
• Rinsing in Water Tank: Neutralises any remaining acid.
• Pre-fluxing: Applies flux to aid zinc adhesion.
• Drying in Hot Chamber: Prepares materials for galvanization by removing moisture.
• Hot Dip Galvanization in Zinc Bath: Ensures uniform zinc coating on the surface.
• Cooling in a Quenching Tank of Running Water: Cools the galvanised materials.
• Cooling in Quenching Tank of DI-Chromate Water: Enhances corrosion resistance and surface finish.
• Finishing: Inspects and trims the materials before roll forming.

Quality Control

Visual and coating inspections are conducted to ensure the finished materials meet the required standards.

Final Inspection and Dispatch

After passing all quality checks, the finished materials undergo a final inspection before being dispatched to the customer, ensuring compliance with project requirements.
