我厂制造各种冲裁模(其单边间隙从0.01mm～0.025mm)为了保证凸模与凹模(或凸凹模)之间间隙均匀分布,多年来我们一直采用镀铜的工艺方法。是采用焦磷酸盐镀铜的工艺方法。该工艺方法与以往氰化镀铜或硫酸铜镀铜相比具有以下优点: 1.属于无毒镀铜 2.镀铜速度快:单面O.03毫米—0.05毫 米/小时, 3.镀层均匀 4.镀层厚时也不会产生毛刺 I plant a variety of blanking die (the unilateral clearance from 0.01mm ~ 0.025mm) In order to ensure the punch and die (or punch) the gap between the uniform distribution, over the years we have been using copper technology. Is the use of pyrophosphate copper process. Compared with the previous cyanide copper or copper sulfate copper plating, the process has the following advantages: 1. belongs to non-toxic copper plating 2. copper plating speed: single side O.03 mm -0.05 mm / hour, 3. uniform coating 4. When the coating thickness will not produce burrs
