To improve the adhesive strength between metal and acrylonitrile butadiene styrene (ABS) resin, a metal surface was embossed with an irregular shape, and then we studied the bonding between different materials by insert molding. The irregular embossing of the metal surface was completed by nickel plating using micro particles of artificial diamond and aluminum oxide. Particles of various sizes were used, and the plating height was set at 1/2, 1/3, and 1/4 of the particle size. When the embossed surface was implemented on the metal surface through the particles, an undercut area was formed on the metal surface. During insert molding, the resin solidified in the undercut area, which increased the adhesive force. As the undercut size was different depending on the plating height and particle size, the adhesive strength varied, and as the particle size increased, the adhesive strength increased. The adhesion strength was higher in the plated specimens using aluminum oxide particles than those with artificial diamond particles. Moreover, the adhesive strength was better with ABS resin containing glass fiber than with pure ABS resin.

为了提高金属与丙烯腈-丁二烯-苯乙烯（ABS）树脂之间的粘合强度，将金属表面压花为不规则形状，然后通过嵌件成型研究不同材料之间的结合。金属表面的不规则压花通过使用人造金刚石和氧化铝的微粒进行镀镍来完成。使用各种尺寸的颗粒，并且将电镀高度设置为颗粒尺寸的1 / 2、1 / 3和1/4。当通过颗粒在金属表面上实施压花表面时，在金属表面上形成底切区域。在嵌件成型过程中，树脂在底切区域固化，这增加了粘合力。由于底切尺寸根据镀层高度和粒径的不同而不同，因此粘合强度会发生变化，随着粒径的增加，粘合强度增加。使用氧化铝颗粒的镀层样品的附着强度要高于使用人造金刚石颗粒的镀层样品的附着强度。而且，含玻璃纤维的ABS树脂的粘合强度比纯ABS树脂的粘合强度更好。
