Engine & Transmission Mounts perform their function in silence under the engine for the life of the vehicle. Their critical function goes unnoticed because they are hidden between the sub-frame of the car and the engine. The combustion noise of the engine combined with its heavy weight pose a challenge when the vehicle is running, and vibrations are further excited by severe road conditions and maneuvers such as braking and cornering. Sigma Engine and Transmission Mounts are designed to match OE standards of fit, function, performance, and materials (natural rubber, high tensile steel, aluminum die cast and polymers) to deliver the desired static and dynamic loads, isolate engine noise & vibration and dampen engine vibrations in extreme weather conditions. Sigma makes a variety of Engine & Hydraulic Mounts, including Switchable Engine Mounts, Pneumatical Switchable Hydro Mounts.
Vehicle body movements experience pitch, roll, and yaw which are usually the result of suspension reacting to turns, braking, accelerations, and road conditions. The primary load-bearing elements on a suspension system is the strut itself which is mounted on the wheel axle at the bottom and to the vehicle body on the top using a Strut Mount to avoid transfer of any vertical knocks into the body. Sigma offers a wide coverage of complete ready to install Strut Super Kit inclusive of all mounting kit components designed to fit & function precisely with the OE and OE equivalent Struts and Springs. Sigma Strut Mount Kits offer the right harmony to enhance your ride comfort by absorbing and reducing the transmission of residual wheel vibrations and noise to the vehicle body.
Suspension Rubber Bushes also referred to as Bushing is a vibration isolator made of rubber, polyurethane or other materials which serves as an interface between two parts while absorbing some of the energy produced by their interaction thus minimizing and limiting the transmission of noise and small vibrations to the vehicle. Bushings are used to absorb the effects of noise and vibration in automotive parts like shock absorber mountings, anti-roll bars, double wishbone suspensions, gear sticks etc. Rubber compound being one of the critical ingredients of Rubber Bushing is produced inhouse and tailormade in Sigma’s own Rubber Mixing Mill as per varied customer and product requirement and monitored batchwise under the strict supervision of qualified Rubber Technologists to ensure quality conforming to OE or OE equivalent standards.
