Benefits of Investment Casting for the Railway 

High Precision

Investment casting allows for the production of intricate and complex components with great precision.

This is particularly important in the railway industry,

where the safety and reliability of components are critical to the operation of trains.

The precision afforded by investment casting ensures that components meet exacting standards,

reducing the risk of failures or malfunctions.


Investment casting is a cost-effective manufacturing process, 

particularly for small to medium-sized production runs. 

It allows for the production of complex components in a single piece, 

eliminating the need for secondary machining, reducing lead times and lowering costs.


Investment casting can be used to produce a wide range of components in various materials,

including steel, bronze, aluminum, and iron. 

This versatility allows for the production of components that are tailored to the needs of the railway industry, 

ensuring that they meet the required strength, durability and corrosion resistance standards.

High-Quality Surface Finish

Investment casting produces components with superior surface finish, 

with the ability to achieve tolerances of +/- 0.1mm. 

This high-quality finish is important in the railway industry,

where it is critical to maintain low friction between moving parts to reduce wear and tear and prevent damage.

Investment casting is used in a variety of applications in the railway industry

Bogie Components

Bogies are a key component of trains, 

responsible for supporting the weight of the train and providing stability and steering. 

Brake Components

Brakes are an essential safety feature of rail vehicles, 

and investment casting is used to produce a range of brake components, 

including brake levers, brake blocks, and brake shoes. 

Investment casting ensures that these components meet exacting standards for strength, durability, and heat resistance.


Couplers are used to connect rail vehicles together, allowing them to be moved together as a single unit.

Gearbox Components

Gearboxes are critical components of rail vehicles, responsible for transmitting power from the engine to the wheels.
