What is die casting? empcasting Empcasting has been serving the top brands like Mercedes Benz, Continental, Huawei from the beginning of our foundation. Beyond the quality of services, we provide we need our customers to have understanding about technical definitions of our services. Die cast aluminum is a kind of aluminum wherein metals are molted under high pressure in the mold cavities. In the die casting process, the metals are hardened and the desired shapes are produced. Aluminum  die casting can be made with the use of either hot chamber or cold chamber process. Aluminum die casting is considered as a non-expendable technique which can be repeatedly used to produce different shapes, sizes and thickness of die cast aluminum. The die casting process can produce variety of shapes with accuracy and attractiveness. What is the Importance of molds for die casting? Die casting process, includes two aspect each of which require an attention. The first is construction of molds and ...

Drum Brake written by Birhan Nega A drum brake system is a system in which a 2 parts drum is used for the brake shoes to make frictional contact with, one part of the drum brake consist of a housing of the brake shoes along with the mechanical constraints and another part of the drum is attached with the wheel hub that rotates with the wheel. The hydraulic pressure generated by the brake oil over master cylinder is transferred to the brake shoes due to which the brake shoes expands and make frictional contact with the rotating part of the drum used. Disc Brake A disc brake system is a system in which a drum of a drum brake system is replaced with a metallic circular disc which is mounted over the wheel hub and also rotates with the rotating wheel of a vehicle, Over this disc used in a disc brake system, A clamp type device called calliper is mounted, inside which brake pads are attached in such a way that the inward movement of these brake pads makes frictional contact w...

Almost all cars currently use what is called a four-stroke combustion cycle to convert gasoline into motion. Modern automotive internal combustion engines generate a huge amount of heat. It has been stated that a typical average-sized vehicle can generate enough heat to keep a 5-room house comfortably warm during zero degree weather. The Necessity of having a good Engine Cooling System contact   Writer An Engine Cooling System is a system that controls the engine temperature, is known as a cooling system. The cooling system is provided in the IC engine for the following reasons:  The temperature of the burning gases in the engine cylinder reaches up to 1500 to 2000°C, which is above the melting point of the material of the cylinder body and head of the engine. (Platinum, a metal which has one of the highest melting points, melts at 1750 °C, iron at 1530°C and aluminium at 657°C.) Therefore, if the heat is not dissipated, it would result in the failure of the cylind...

TYPES OF AUTOMATIC TRANSMISSION 1. Traditional Automatic Transmission It also is known as self-shifting transmission, n-speed transmission or torque converter automatic, this is the standard type of automatic transmission to be found in most of the cars these days. Unlike a manual gearbox, it does not use a clutch to change gears. Instead, a hydraulic fluid coupling or a torque converter does this job. It connects to the Electronic Control Unit of the engine and allows for precise control of the vehicle. It is a type of transmission that automatically changes gear ratios as the vehicle moves. The benefits of an AT center on giving drivers freedom from shifting gears manually. Other advantages include a smooth and precise engine control. Note that AT can be found in many non-MT vehicles. Automatic cars perform smoothly, but the shifting of the gears is not quick all the time, earning them the name ‘slushbox’. The impression has been changing though, thanks to some brilliant tr...
