非标螺栓的表面处理种类:

表面处理即是通过一定的方法在工件表面形成覆盖层的过程,其目的是赋以制品表面美观、防腐蚀的效果,进行的表面处理方法都归结于以下几种方法:

1、电镀:将接受电镀的部件浸于含有被沉积金属化合物的水溶液中,以电流通过镀液,使电镀金属析出并沉积在部件上。一般电镀有镀锌、铜、镍、铬、铜镍合金等,

有时把煮黑(发蓝)、磷化等也包括其中。

2、热浸镀锌:通过将碳钢部件浸没温度约为510℃的溶化锌的镀槽内完成。其结果是钢件表面上的铁锌合金渐渐变成产品外表面上的钝化锌。热浸镀铝是一个类似的过程。

3、机械镀:通过镀层金属的微粒来冲击产品表面,并将涂层冷焊到产品的表面上。


冷锻机我们目前包括一模二冲、二模二冲、二模三冲、二模四冲、三模三冲、开合模等,使各类螺钉产品,如木工螺丝,自攻螺丝,纤维板钉,干壁螺丝、各类铆钉、车轴件等,从简单类型到各种结构复杂的类型——可以用冷镦机形成头部和柄。
