In this blog, we discuss what railway castings are and why quality must be considered when buying railway castings. We also outline what to look for to ensure the castings you purchase are of the highest standard.
What are Railway Castings?
Railway castings are parts made of Iron and steel used to make railway carriages and tracks. For example, you can use these to create the wheels of a train.
You can also use them to create the tracks that trains run on. The castings are small but designed to provide trains with the grip and strength they need to operate smoothly and efficiently.
Why is Quality Important for Railway Castings?
Railway castings need to be of top quality for several reasons. They have to tolerate heavy loads. These also have to function at a very high speed. The conditions that railway castings operate in can be very stressful.
If their quality is excellent, their risk of damage is reduced. You ensure the safety and security of railway passengers when you create tracks and carriages that are made of high-quality castings.
Top Things to Consider When Buying Railway Castings in Kolkata
You need to consider the following factors if you want to buy the best railway castings from a railway castings supplier Kolkata -
1. Check for the Materials the Casting is Made from
The first thing that you need to look for when you buy a railway casting is to check the material that it is made of. You must always ensure that it is made of Iron or steel. You should also ensure that this Iron or steel is the finest there is.
2. Assess the Durability of the Casting
Once you have checked the materials the casting is made of, the next thing you should look for is its durability. Castings need to tolerate heavy use because they function in extreme conditions.
You need to see, for example, if the castings you buy can resist rust or corrosion.
3. Look for Dimension Accuracy
Dimension accuracy is yet another thing that you need to look for when you buy railway castings. These need to be of the right size and dimensions. Their surface must be smooth and free from defects.
If you buy a casting made of Iron, you should check whether it has a silvery, smooth surface. If it does, it is likely to be of excellent quality.
4. Make Sure International Standards are Followed during Manufacture
Apart from checking whether the casting dimensions are accurate, you should also find out whether the latest global manufacturing standards have been followed in their production. Castings that are made by following the latest international standards are likely to last longer and withstand wear and tear more easily.
5. Inquire About the Manufacturing Methods Used
You should also learn about the methods used to produce the iron and steel rail castings you buy. The process followed to make a casting plays a significant role in determining whether it turns out to be of high quality.
You should, for example, check whether the parting surfaces and the primary manufacturing methods are carefully chosen. Proper manufacturing techniques ensure that the castings produced are not fragile or porous.
Such techniques also ensure that the castings produced will not crack easily.
6. Find Out about Temperature, Cooling Time and Pouring Rates
Some other things you must check when looking into the quality of the railway castings you buy are the temperature at which the castings were produced and the time allowed for cooling. Molten metal, when allowed to solidify over a long period, becomes more rigid and more durable than it would otherwise.
You should also consider additional factors, such as the casting material’s permeability and pouring rates. You should also find out whether the manufacturer conducted any chemical or paint tests when creating the metal castings.
7. Determine Quality based on the Cost of the Casting
You can also determine the quality of a metal casting based on how much it costs you. The cost of these products is usually known to depend on factors such as the size of the casting and grading.
If the casting you buy is expensive, it is likely of superior quality. Low-priced castings may not be perfect.

Frequently Asked Questions
What castings are used in the railways?
Castings are used in the railway industry to create the tracks on which trains run. These can also be used as the carriages of a train.
Why is it essential to use good-quality castings in railways?
The castings that are used in the railway sector always need to be of the highest standard. Trains move at a rapid speed. The weather conditions under which trains sometimes operate can also be unpredictable.
If castings are of high quality and can function well in high-speed situations, regardless of whether the weather is bad. They can tolerate heavy loads and withstand the wear and tear that can occur when running on tracks.
Does design influence casting quality?
Design does affect the quality of a railway casting. A good design means the casting produced will not be porous and will not shrink or tear easily. A poorly designed casting is unlikely to perform well.
Is heat treatment needed during casting?
Yes, heat treatment is commonly used in casting processes. It is done to make sure that there are no impurities around the casting once it has been formed.
Are shell mould casting and sand casting the same thing?
Sand casting and shell mould casting follow the same processes. For sand casting, the mould is made using green sand. In shell mould casting, the mould is made using sand that is coated with resins.
