Before the industrial aluminum extrusion molding production process is actually a kind of aluminum extrusion mould customization, is much more common on the market became a conventional aluminum extrusion. Now the aluminum extrusion mould custom actually refers to the irregular cross-section profile customization. Conventional aluminum extrusion production you just need to extrusion molding, but open mold custom the early stage of the aluminium profile extrusion is there are a lot of working procedure, because the custom profile is special, only without the second. Such profiles production need to pay attention to what issues? Today we speak of one of the most need to pay attention to three questions:

The first: aluminum extrusion mould customized mould must be qualified. Open mold custom tool steel mold is the high precision level. Because the mould need high wear resistance. Need the mould rigidity, light weight, high surface finish and dimensional accuracy. Some complicated shape, aluminum profile machining difficult, need to use cold extrusion processing molding process can be easily.

Second: aluminum extrusion mould custom profile must be qualified raw materials. The current industrial aluminum extrusion materials are generally 6063 - T5 aluminum alloy, also have a plenty of 6061 aluminum alloy. But many manufacturers in order to save costs, using recycled aluminum adding in pure aluminium melting into alloy extrusion, the produced aluminum extrusion surface can't see any different, but very short service life. So the profile of the raw materials must be qualified, to guarantee the aluminum extrusion mould custom qualified!

Third: aluminum extrusion mould custom profile surface treatment must be qualified. The surface of the aluminum extrusion processing is generally anodic oxidation. Conventional anodic oxidation is generally is silvery white, but the mould of custom can be any color of RAL system. Qualified surface treatment is refers to the thickness of oxide film to amount to mark, color should be correct, even.
