Our focus will always be towards the future. The technology in the automobile industry is constantly evolving and the bright minds at Sankar are at the forefront.
Sankar with the help of CAD is able to create the models of the gaskets as well as the tools that are required to produce the gaskets. With CAD we are able to significantly improve our overall development speed as well as quality since the tools are developed based on the drawings.
In order to avoid the escaping gas from an engine affecting overall performance during operation, the proper pre-stressing force of the bolts and the gasket design are taken into account to enhance the efficiency of the sealing of the gasket.Finite element analysis (FEA) is a computerized method for predicting how a product reacts to real-world forces, vibration, heat, fluid flow, and other physical effects.
The Fuji Film Analyzer use to measure the pressure distribution pattern to conforming the static sealing requirements. For this we use a unique material and it is sandwiched between the engine part and the gasket and the exact bolt force is given to see how well the gasket seals. Providing a good seal is the primary responsibility and at the appropriate load, the gasket should provide the best seal possible.
At Sankar’s Research and Development Center, we have a fully-fledged Deep Thermal Shock Testing facility. Its main purpose is to accelerate durability testing of engines and engine critical components such a cylinder head gaskets deep thermal shock test will be conducted in the temperature ranging from -30°C to 110°C. The advantage of this being that we can help customers by testing their engines at our facility and make sure that it performs according to the specifications.
Engines vary combustion parameters to achieve different purposes such as efficiency, speed, power, and peak pressure occurs in every cycle, as such when running at maximum speed or torque there is a slight lift in the upper half of the engine, the cylinder head lifts from the engine block thus hammering the gasket between, leading to gasket failure, to resolve this cylinder head lift measurement analysis experiment will be carried out in development stage.
A unique and patented system developed in-house at Sankar. The Bolt Force Measurement System is used to measure and record the change in bolt forces which is experienced during static, dynamic testing, and pulsate testing. This is very helpful for our customers as well as us since we can develop gaskets with more performance and precision possible by our competitors providing Sankar a unique advantage.
In multi-cylinder engines temperature varies from cylinder to cylinder. The temperature difference may lead to elongation of the differential bolts.To analyzethis change of temperature, this particular experiment will be carried out during the engine development phase.
Most of today’s gaskets have contours. These help in providing better sealing properties. For testing whether the contours in the gaskets are conforming to the specifications specified by the customer, we have high precision contour measurement devices.
With the high precision measurement, we are able to pin point even the slightest variations in the contours quickly and the make the necessary modifications during the development phase.
This instrument is used to critically assess the pressure inside the bore to make sure that the pressure is well within the specifications. This also helps confirm that the gasket is performing according to what the customer requires.
The material that we receive and the gasket that we manufacture have specific standards that they have to adhere to. One specific standard is surface roughness. This affects the overall compatibility of the gasket with the components it is intended to seal.
