Insufficient drum speed: Insufficient drum speed will lead to patch phenomenon between parts and parts or between parts and drum wall, thus forming drum marks.
Improper shape of the drum: When using a thick and short drum, due to the large linear speed, it is easy to cause abrasion of the plating layer, knocking corners or knocking edges and other phenomena, thus producing drum marks.
Problems with plating solution: Improper parameters such as composition, temperature and pH value of the plating solution may also lead to roller marks.
Methods for solving barrel marks
Increase the drum speed: Under the premise of not producing other effects (such as plating wear, knocking corners or knocking edges, etc.), try to increase the drum speed, which is an effective measure to alleviate the patch between parts.
Adoption of long and thin drums: The long and thin drums have less linear speed at the same angular speed (RPM), which makes the wear of the plating layer and the phenomena of knocking corners or edges less severe, and thus is more conducive to the use of high RPMs.
Use of accompanying plating materials: The use of accompanying plating materials such as steel balls can effectively prevent the patch phenomenon between the parts and the drum wall.
Adjustment of plating solution parameters: Adjust the composition, temperature and pH value of the plating solution according to the specific situation in order to minimize the production of roller marks.
Specific operation steps and precautions
Increase the rotating speed of the drum: Increase the rotating speed of the drum gradually according to the specific situation, and at the same time, pay attention to observe the quality of the plating layer to avoid generating new quality problems.
Choose the right shape of the drum: the slender drum has less wear on the plated layer under the same rotating speed, which is suitable for high-speed plating.
Use of accompanying plating materials: choose suitable accompanying plating materials, such as steel balls, according to the size of the parts and patches, and adjust its ratio.
Adjust the parameters of plating solution: according to the composition of plating solution and process requirements, adjust its temperature, pH value and other parameters to ensure the stability of plating process.
Regular maintenance and inspection: Regularly maintain and inspect the rollers and plating equipment to ensure that they are in good working condition.
