pressure die casting aluminium alloys.Improve the precision of aluminum alloy die casting

　　Now the aluminum alloy die-casting more and more precision, but the high-precision die-casting is not so good to do, although the casting performance of the die-casting aluminum alloy is very good, can die casting a variety of more precise die-casting, but in order to really achieve high precision, or need to carry out a variety of post-processing, cnc is to improve the dimensional accuracy of aluminum alloy die-casting parts must be selected processing technology.

　　When aluminum alloy die casting is engaged in cnc processing, due to the particularity of the material and process, several points need to be paid attention to, if we do not notice, then the aluminum alloy die casting is damaged. One is the control of the feed amount, which needs to be controlled as small as possible; The second is to choose the right cutting fluid; The third is to minimize the damage to the dense layer, the surface of the aluminum alloy die casting is a thin dense layer, the thickness is about 1 mm, and the dense layer below is a loose porous organizational structure, like bread.

　　Die casting mold factory production of die casting mold is a necessary tool for die casting production, die casting molding is the use of die casting mold to complete, can be called the mother of die casting, the production of die casting mold requires considerable experience and technology, so die casting mold factory fees are often relatively high, so now many die casting factory began to establish their own mold room, their own production of die casting mold.

　　These die casting plants through many years of "self-production and self-marketing", has not lost to die casting mold factory production experience and technology, and because it is customized, die casting mold any problems can be timely feedback, die casting mold makers can clearly know their own problems where? Can better correct their own mistakes, help their own production more in line with their own special die casting mold, in the eyes of those who do customized products, this is more secure than buying die casting mold from die casting mold factory.
