Cylinder Blocks are made of gray cast-iron, ought to have desired casting and machining qualities, viz. strength, toughness, hardness and wear resistance. Air Cooled Blocks are ideal for heat dispersion, these are widely used in compressors, generators, trucks, engines, and many more.

These are mainly of two types – Air Cooled Blocks and Wet Cooled Blocks.

In order to meet with industrial quality standards, we manufacture these Blocks from sand casting The inner bores are cross honed to provide maximum smoothness to the surface, that in turn reduces friction, when this inner bore is contacted with Piston Rings.

Quality:

• A very good plateau honing and cylindrical grinding that matches the geometrical parameters.
• Stringent material along with microstructure analysis of all the batches individually.
• Complete dimensional inspection of the finished components included in the process.
• Inspection of honing angle, structure and surface roughness at random.
• Tests of profiles, tensile strength and crack detection at regular intervals in a random way.
• Manufacturing experience for the past 25 years and an expertise with single roof manufacturing outlet.
• A very wide range and suitable for up to 1500 models for worldwide tractors, Diesel Engines, Stationary Engines and industrial engines.
• Can produce Blocks in bulk as well as small quantity in our patch production unit.Product Range:
  • Phosphated Cylinder Block
  • Chromed Cylinder Block
  • Air Cooled Cylinder Block
  • Water Cooled Cylinder Block
  • Finned Cylinder Block
