About Cylinder Head Gasket
We have made it our goal to manufacture high quality gaskets, deliver our products on time, and provide exceptional customer service. We are dedicated to customers in all Automobile, Marine, Earthmoving & Other industrial sectors needing standard & custom gaskets of superior workmanship. With die cutting, slitting, water jet cutting, VMC Cutting and some times manual cutting capabilities, Dev precision Engineers works with a variety of metals & other Composite materials to meet all of customers needs. We have high production rates as well as Smaller Quantiy, a short production cycle and reduction in product finishing time.
A head gasket sits between the engine block and cylinder heads and is a vital part of internal combustion engines. The gasket must perfectly fit the contours of the cylinders, the engine block and the cylinder head to ensure the engine’s efficiency and safety. Head gaskets are essential components because they prevent fuel, heat, and exhaust from escaping the combustion chamber and threatening other engine components. They also prevent inefficiencies in the combustion process, but most engineers and consumers think of efficiency as secondary to safety in an explosive reaction. If head gaskets fail, heat from the reaction can degrade other engine parts. Coolant and oil can enter the combustion chamber and mix with fuel. If these or other problems persist after a gasket fails, it can cause catastrophic engine failure. As the most critical sealing application in any engine, head gaskets are imperative to insure your motor runs correctly.
About Cylinder Liners
Cylinder Liners are made of gray cast-iron, ought to have desired casting and machining qualities, viz. strength, toughness, hardness and wear resistance.
These are mainly of two types – Dry liner and Wet liner.
The liners are ‘cast-in fit’, force (press) fit or slip fit.
The interference between its outer diameter and bore-hole walls depends on fit-type from 0.050 to 0.075 mm. These are available in wide range suitable for light, medium and heavy duty application.
In order to meet with industrial quality standards, we manufacture these liners from sand casting and centrifugal casting, which enables us to maintain the uniform hardness all over. Apart from this, we also keep into consideration various factors including distortion-less bore and low thermal expansion to meet with the requirements of our clients. These liners are available in semi finished as well as full finished sizes. Cross honing is done on the full finished products to make the inner bore distortion-less. 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.
WET CYLINDER LINERS manufactured by the “CENTRIFUGAL CAST PROCESS” is acknowledged to be the best method. It possesses the bearing metal qualities that cause skin healing after abrasion and a structure that is readily wetted by oil and retains an oil film. Corrosion resistance is further improved by adding Chromium in the metal.
We also accept the customized orders of our clients and manufacture these products in accordance with the samples and drawings with the given material & coating.
Quality:
- Centrifugally cast cylinder liners of actual quality along with precise machining.
- A very good plateau honing and cylindrical grinding that matches the geometrical parameters.
- Manufactured with chromium and nickel elements maintaining the BS4K6 material standard.
- 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 a 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 cars, trucks, tractors and industrial engines.
- Can produce liners in bulk as well as small quantity in our patch production unit.
Process:
In the centrifugal casting process, the molten metal is poured into a metal mould or die which is revolving at a high speed. The centrifugal force causes the metal to distribute itself evenly around the die. The resulting casting are of much finer grain and free from blow holes or porosity. A further important advantage is that the impurities, being lighter than the iron, are forced centrifugally to the bore surface from which they are removed by machining.
- The centrifugal casted liners are 10% heavier than sand casted liners, because they are close grained, & hence more durable
- They increase the life span of engines by 25% to 30%
- These liners have less wear along with scuff resistance for a longer period
- They can give better life to your vehicles with molly hard rings and molly hard liners.

It also combines favorable antifriction properties with good load-carrying capacities and will conform to slight shaft misalignments.
Typical uses:
- General purpose bushings
- Bearings
- Washers
- Non-pressure applications
- High speed – light load bushings
- Mild acid applications
- Bearings and bushings with machinability and anti-seizing properties
- High speed – heavy pressure bushings
- Bridge parts
- Bearing plates
- Low friction – moderate pressure bushings
- Railroad applications
