Abstract

The invention relates to the technical field of metal material machining, in particular to a bimetal forming method and a product thereof. The bimetal forming method comprises the steps that an outerframe blank part of the product is manufactured out through CNC machining of the first time; the outer frame blank part of the product is placed in a mold, and then an inner component of the product is formed through die casting; the outer side face of the outer frame blank part is machined through CNC machining of the second time; and the outer frame blank part of the product is made of a first metal material, and the inner component of the product is made of a second metal material. Compared with the prior art, in the bimetal forming method, through CNC machining of two times, forming machining of the inner component and the outer structure of the product is completed in sequence, and the situation that shrinkage depression and air holes happen to the surface of the obtained product is greatly reduced; and the work hours are shorter than the work hours consumed by CNC forming of only one time.

Description

【Technical field】 [0001] The invention relates to the technical field of metal material processing, in particular to a bimetal forming method and its products. 【Background technique】 [0002] In recent years, electronic product-related industries represented by smart terminals have developed rapidly. The appearance innovation of smart terminals has attracted people's attention, and the trend of metallization and thinning of products is becoming more and more popular. Metal casings have obvious advantages over plastic casings in terms of casing thickness, heat dissipation performance, and recyclability. Therefore, the molding process of metal casings has become a key research direction in the industry. [0003] Bimetal forming is an emerging research direction, that is, the outer frame and inner parts of the product are formed by composite die-casting of different metals. Such products can combine the performance advantages of different metals. [0004] The CNC machining o...
