Investment Casting for Locomotives, Metro Systems, and Railway Applications
Durable, Safety-Critical Castings for Rail Couplings, OHE Fittings, and Wagon Components
Railway applications demand dimensional stability under vibration, cyclic loading, and decades of service. Investment casting ? also known as lost wax casting ? delivers exactly the consistency rail requires.
Pahwa MetalTech supplies precision castings for locomotive systems, metro rolling stock, overhead line equipment, and freight wagons ? parts that meet tight tolerances and are traceable to railway quality standards.
Tin bronze, high-tensile brass, and stainless steel are the core alloys for railway castings ? chosen for load-bearing performance, resistance to wear and fretting, and suitability for traction and OHE service.
