Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, and die.

An aluminum alloy is a composition consisting mainly of aluminum to which other elements have been added. The alloy is made by mixing together the elements when aluminum is molten (liquid), which cools to form a homogeneous solid solution. The other elements may make up as much as 15 percent of the alloy by mass.

A balance bike, run bike or no pedal bike or dandy horse is a training bicycle that helps children learn balance and steering. It has no foot pedals, no drivetrain, no chain, no gears, no gear shifters, no derailleurs, and no freewheel. Balance bikes have been made out of both metal and wood. It can be a normal bicycle with pedals and related parts removed, or it can be purpose-built (especially for very small children, for whom normal bicycles are generally not available).

A Nissan clutch disc is part of the device on a car or truck that is designed to disconnect the motor from the transmission when the clutch is pushed. Because a huge amount of heat is generated when your vehicle's Nissan clutch disc is pressed into the pressure plate, the frictional surface wears off and the clutch has to be replaced.

In a VW, the flywheel is attached to the rear end of the engine crankshaft engine, and the Vw clutch plate is connected to the transmission by way of the splined shaft that protrudes from the rear end of the transmission.
