                    Precision machining for brass die cast products

       Brass die casting process is suitable for volume production of copper machinery parts. Those die cast copper

machinery parts can have fine surface smoothness and dimensional precision. Currently a variety of copper or brass

pipe fittings are produced by high pressure die casting process, because of their high demand. Since the melting

point of copper alloy is quite higher than that of zinc and aluminum and foundries always apply hot chamber die

casting machines for brass die casting, brass die casting mold is subject to deviation and frequently maintenance.

So commonly post precision machining is necessary for critical mating surface and connecting features of copper or

brass die cast machinery parts.

    

  We can offer both the cold chamber process and the hot chamber process. In the cold chamber process the metal

is ladled into the injection chamber for each shot. There is less exposure of the molten metal to the chamber walls

and plunger. This is very useful for aluminum and copper alloys that would easily alloy with iron at elevated

temperatures. The hot chamber process has the injection chamber which is connected to the die cavity permanently

immersed in the molten metal. The hot chamber process is used for metals of low melting point and high fluidity such

as tin and zinc.

Minimum wall thickness and draft angles for die castings are as follows:

Material                         Min. Thickness                         Min. draft angleAluminum                      0.9 mm ( .035 in )                    0.5 degreesZinc alloys                      0.6 mm ( .025 in )                    0.25 degreesCopper                           1.25 mm ( .050 in )                  0.7 degrees

The materials that Donrex offers are alloys of aluminum, copper, zinc and magnesium. Zinc castings can be made

with thinner wall thickness than aluminum due to high melt fluidity.
