What is the light alloy die casting

   Light alloy refers to the alloy for density less than 5 grams / cubic centimeter. Usually is alloy of aluminum, magnesium, sodium, potassium, calcium, strontium, barium, etc..
   Light alloy strength and stiffness less than structural steel. But their density is small, specific strength (strength / density) and specific stiffness (elasticity modulus/ density) is relatively large, similar to the structural steel even high strength steel, so the light alloys are widely used in aerospace field, in order to reduce the weight of the aircraft, to improve the carrying capacity and speed.
   Light alloy die casting: molten alloy into the mold cavity and applied pressure, the liquid alloy solidification in the mould cavity, the formation castings.

Why die casting mold making will generate the stripe

    The reason of die casting mold making forming the stripe:
    At the front end of the liquid metal temperature is too low, meet incomplete fusion, a mark.
    The improvement of method:
    Check the wall thickness whether too thin (design and manufacturing), the thin area should be directly filling.
    Check the shape whether easy to filling; distance is too far, enclosed area (such as fin, convex), blocked the area, fillet region is too small and so are not easily filling. And pay attention to whether there is a rib point or cold spots.
    Shorten the filling time.
    Change the filling way of die casting mold making.
    Increase mold temperature
    Raise the temperature of molten metal.
    Check the composition of the alloy.
    Increasing the exhaust passage or add vacuum device, reduce the filling resistance.

What is the metal stamping

     Metal stamping is the use of punch and die stamping iron, aluminum, copper and other metal sheet, so that its deformation or fracture, with a certain shape and size.

     Hardware stamping is sometimes called sheet forming, but slightly different. The so-called plate forming refers to the plate, thin wall tube, thin material as raw material. Method of forming of plastic processing is called sheet metal forming, at this time, the deformation of the plate thickness is generally not considered emphatically.

     The ramming profession is the an extremely wide range of industries involved in the field, deep into all aspects of the manufacturing sector. The metal stamping parts supplier development should be attributed to the development of the automotive, aircraft and appliances daily necessities.
