Introduction to metro parts fabrication
As part of urbanization, India’s metro rail network is growing at an unprecedented pace. Metro rail routes are expanding across major cities such as Delhi, Mumbai, Bengaluru, Pune, Hyderabad, and Chennai to meet evolving transportation demands. During their life span, the metro rail parts are subjected to dynamic loading, continuous vibration, and other extreme conditions. To ensure the safety of the onboard passengers, rail workers, and the operational efficiency of the trains, the metro parts fabrication requires micron-level dimensional accuracy, repeatability, strict adherence to OEM drawings, and controlled welding procedures.
Even the slightest defects and dimensional errors can severely affect the performance, alignment, and long-term durability of the metro rails. This is why choosing a reliable fabrication partner who can combine technical expertise with thorough execution is important.
Cyclotron Industries positions itself as a reliable, engineering-driven metro parts fabrication partner in Pune and across India. With an in-house facility, strong manufacturing capabilities, and skilled expertise, we cater to the specifications of metro rail suppliers and OEM contractors.

- Capability to produce both batch-wise and custom metro parts: From repetitive production runs to drawing-based custom parts, we keep consistency across every batch.
- In-house advanced fabrication infrastructure: We have an in-house facility with CNC laser cutting, precision bending machines, and controlled welding stations, which can support the manufacturer of complex metro components.
- Skilled welding & quality control procedures: We employ skilled welders and trained inspection personnel to ensure compliance with the welding procedures and quality standards.
- Detailed documentation and traceability: Critical documentation, like material traceability, inspection records, and compliance documentation, is integrated into our workflow to meet our project requirements.
Our Metro Parts Fabrication Capabilities
Metro projects demand fabrication that is accurate, repeatable, and structurally reliable. At Cyclotron Industries, our metro parts fabrication capabilities are designed to handle both heavy structural members and precision-engineered components for rolling stock and infrastructure systems.
- Materials & Grades
We use certified materials in accordance with project specifications and OEM drawings.
- Mild steel and high-tensile steel: Chosen for structural strength and load-bearing assemblies.
- Stainless steel: It is preferred to add corrosion resistance in exposed or moisture-prone environments.
- Special grade alloys: They are chosen strictly as per the metro OEM drawings and technical requirements.
At Cyclotron Industries, we maintain material traceability from the time of inspection to final dispatch. Heat numbers and certificates are recorded properly, as the metro projects do not accept any ambiguity.
2. Fabrication Processes
Our fabrication process flow is structured and controlled. Each stage is monitored to maintain dimensional accuracy and reduce distortion.
- CNC laser and plasma cutting for precise profile cutting with minimal edge deviation.
- Precision bending and forming using calibrated machines to maintain angle accuracy.
- MIG, TIG, and SAW welding executed as per approved procedures and qualified parameters.
- Machining, fit-up, and sub-assembly to ensure proper alignment before final welding.
- Surface preparation and painting for corrosion protection and finish quality.
We follow a systematic approach. Fabrication is not rushed. Each component passes through inspection checks at defined stages. This helps in delivering consistent quality in every production batch.
Through strong material control and disciplined fabrication processes, Cyclotron Industries ensures dependable metro parts fabrication for demanding urban rail projects.
Metro Train Structural Parts Fabrication
Metro train structural components make the backbone foundation of the rolling stock’s performance and safety. These metro rail parts must withstand constant dynamic loads, constant vibration, and long operating cycles without structural fatigue or dimensional deviation. At Cyclotron Industries, we carry out specialized precision fabrication of the following components:
- Underframes & structural assemblies: They are built to support the entire structural load of the coach, maintaining rigidity and alignment.
- Equipment mounting frames: These frames are designed to secure the installation of electrical appliances, braking systems, HVAC units, and auxiliary equipment.
- Load-bearing & vibration-sensitive components: These types of critical components are fabricated with controlled welding methods to reduce distortion and residual stresses.
Dimensional accuracy: Thorough dimensional accuracy is maintained by our team through calibrated fixtures, controlled fabrication practices, and strict inspections. This enables accurate integration during final assembly and reduces the need for on-site adjustments for OEMs and system integrators.

Metro Bogie & Running Gear Fabrication
The bogie and running gear assemblies on the track are constantly subjected to dynamic stress, constant vibrations, and load transfer. The decision in metro parts fabrication should be designed to ensure the structural stability, rider safety, and long operational life.
- Bogie frames & cross members: We fabricate these components with high-dimensional control to maintain axle alignment and structural rigidity.
- Brackets, stiffeners & reinforcements: They are designed to increase strength and distribute load.
- Welding fixtures for consistency: Designed to provide repeatability, reduce welding distortion, and maintain consistency batch after batch.
With controlled fabrication practices and inspection methods, we focus on minimizing residual stresses and increasing structural rigidity.

Quality Standards & Inspection for Metro Fabrication
Metro fabrication is more complex than normal fabrication work. Making even a small mistake can create a serious problem during operation. Because of that, quality control is taken very seriously at Cyclotron Industries. Quality control is not followed only at final inspection. It starts from the material selection stage itself.
Our Quality System Covers:
- Approved Welding Procedures WPS and PQR
We carry out all the welding activities in accordance with the approved WPS and PQR. Welding parameters are controlled, and the welders follow qualified procedures. This helps maintain strength and consistency across every production batch.
- Dimensional and Fit-Up Inspection
Before welding, proper fit-up inspection is done. Alignment, gap, straightness, and squareness are verified as per the drawing. After fabrication, full-dimensional inspection is carried out to ensure tolerance compliance. This reduces rework and site issues.
- Visual and NDT Testing DPT and MPI if required
Visual inspection is done at different stages of fabrication. If the project specification requires, we conduct Non-Destructive Testing including Dye Penetrant Testing (DPT) and Magnetic Particle Inspection (MPI). These tests help in identifying surface cracks or weld defects.
- Full Traceability and Inspection Documentation
Material heat numbers, inspection reports, weld records, and quality checklists are properly maintained. In metro projects, documentation is equally important as fabrication. Without proper records, approval becomes difficult.
For metro parts fabrication, safety and reliability are critical. That is why our inspection system is structured, documented, and consistent. We focus on doing the job correctly the first time, not fixing later.
Selecting the right partner for metro parts fabrication is critical. At Cyclotron Industries, we bring practical experience and process discipline to every project.
- Strong expertise in railway and metro fabrication
We understand structural load paths, welding sequence control, and dimensional sensitivity required in rolling stock and metro applications.
- Controlled welding and distortion management
Welding heat can distort structural members if not handled properly. We use planned welding sequences, fixtures, and inspection checks to maintain alignment and dimensional accuracy.
- Reliable delivery schedules
Metro projects run on tight timelines. Delays in the fabrication of components can impact assembly and commissioning. Our production planning and batch control systems are aligned to meet committed schedules.
- Suitable for Tier-1 and Tier-2 metro suppliers
We are structured to support established metro vendors, rolling stock manufacturers, and infrastructure contractors who require compliance, documentation, etc
