Foundry Shop

There is well-equipped and modernized foundry running in HMT. There are 3  electric furnaces working in the foundry. All the requirements of tractor division and machine tool division are fulfilled by this foundry. Casting is the final product of the foundry. Liquid metal is poured into mould and the molten metal takes the shape of the cavity.

Crank Case

It is made of cast iron.

Other parts of the engine are directly or indirectly attached to it.

It is equipped with holes, by which the engine may be firmly anchored to its foundation.

Cylinder

A cylinder is the central working part of a reciprocating engine.

Cylinders are made of high-grade grey cast iron.

It act as combustion chamber for the engine.

Piston & Connecting Rod

Piston of an engine move back and forth in the cylinder owing to the explosion of the fuel mixture.

Piston is surrounded by piston rings which prevent the friction losses.

Connecting rod connects the piston and crank shaft

Engine Testing

After assembly, engine is brought to engine testing section. In this section practical checking of engine is done on engine and water

supply is connected to it, then the engine is started with the external DC supply.

After this, the proper operating of valves is done, the engine is kept running for two hrs.

During running the load is also varied and various properties like lubricating oil pressure, load capacity, fuel consumption etc is checked.
