Castings for the Railway Industry – What Are the Latest Trends?
Railways are being modernized: new vehicles are expected to be lighter, more energy-efficient and easier to maintain. This changes the requirements for castings. Below, we describe the most important trends in railway castings.
1. Lightweight aluminum alloys
More and more rolling stock components are made of aluminum – a lighter vehicle uses less energy and puts less load on the track. Aluminum castings are used, among other things, for housings of electrical equipment and drives, brake system components, brackets and covers.
2. Modern casting techniques
Permanent mold and die casting produce repeatable, accurate castings with a good surface finish, while CAD design and simulation shorten the launch of new parts. Short runs and spare parts for older vehicles are often made in sand molds.
3. Durability and corrosion resistance
Rail components operate in humid conditions, under varying temperatures and vibration. Choosing a corrosion-resistant alloy, inspecting the castings and applying protective coatings, such as powder coating, extend service life and reduce maintenance costs.
4. Sustainable production and recycling
Operators and rolling stock manufacturers increasingly ask about the environmental footprint of parts. Aluminum can be remelted repeatedly, and remelting uses only a small fraction of the energy needed to produce primary aluminum.
5. Custom-made parts
Rolling stock modernization and short vehicle runs are increasing demand for castings made to customer-specific documentation, including spare parts that vehicle manufacturers no longer supply.
Summary
The main trends in castings for the rail industry are lightweight aluminum alloys, repeatable casting technologies, greater durability and corrosion resistance, recycling, and made-to-order production. We make aluminum castings for the rail industry to the customer's documentation – read more on the page castings for the rail industry.
