During the plating degreasing process, it is important to properly clean grease and dirt from the workpiece, especially from inside the blind holes, as this ensures uniformity, adhesion and overall quality of the plated layer. Here are some suggestions for cleaning blind holes in plated parts:
1. Selection of suitable cleaning agent: Use electroplating degreasing powder designed for pre-treatment use, such as Bigely steel electrolytic degreasing powder BC-1105, which can emulsify and disperse grease and remove dirt well.
2. Application of ultrasonic cleaning technology: through the use of ultrasonic equipment in the cleaning tank, the cleaning solution can be made to penetrate deep into the interior of the blind holes, and the cavitation effect produced by the ultrasonic waves helps to loosen and remove the dirt inside the holes.
3. Adjusting the cleaning temperature: Increasing the temperature of the cleaning solution helps to improve the cleaning effect. However, the temperature should not be too high, so as not to affect the material of the workpiece or create a safety risk.
4. Use of high-pressure jets: High-pressure jets can powerfully inject cleaning fluid into the interior of blind holes to assist in the removal of grease and other stubborn dirt.
5. Mechanical methods to assist chemical cleaning: before chemical cleaning, you can try to remove large surface particles of stains by mechanical means such as manual brushing, air blowing, etc., in order to reduce the burden of chemical cleaning.
To summarize, ensuring that the cleaning inside the blind holes before plating is thorough and in place is a prerequisite for obtaining good quality plating. Different materials and structures may require the use of different plating degreasing powders, if you want to achieve good plating results, you can consult with Bigely engineers to get the appropriate technical solutions.
