10 Years Manufacturer Precision Casting Wax to Frankfurt Manufacturers Detail:
Precision Casting Wax mainly is used for precision mechanical process with zero allowance or very limited allowance. We can not adopt general casting technique, but can only adopt zero allowance casting or precision casting. Because of the product’s structure is very delicate and complex especially in bejeweled with golden and silver, such as diamond ring, brooch, earring etc.
The characteristics of precision casting wax are: good coating property, no denaturalization to be heated, good flow ability, good thermal stability, and well surface finish.

Mercedes Benz introduced its Camtronic variable valve lift system on the M270, used on the C class series four cylinder engine in 2012. Called Camtronic, its main purpose is not to increase power, but to increase fuel efficiency. At light or part load, the Camtronic switches to a low lift cam profile to limit the amount of air intake, and at the same time the throttle butterfly can remain wide open, and reduce pumping loss. This is similar to BMW’s Valvetronic system that uses an electric motor, and is discussed elsewhere in this series. But, the Camtronic is a 2 stage system, rather than continuously variable. The mechanism of Camtronic is pretty simple. The intake camshaft is served with a conventional variable cam phasing actuator at the end of it, as well as the Camtronic variable valve lift electric actuator normally mounted at the top of the head.
The camshaft itself consists of an inner spline carrier shaft, and 2 hollow cam lobe pieces, each serving 2 adjacent cylinders. Mercedes Benz engineers refer to these as cam-pieces, of which the first controls the intake valves of cylinders 1 and 2, and the second those of cylinders 3 and 4. Each cam has 2 cam lift profiles, or low and high lift. The cam profile that is engaged depends on the …
