Ball Point Pen Tip Cleaning
Ultrasonics has become indispensable for cleaning turned products. In fact, turned products require thorough cleaning, yet their most delicate parts such as external threads or surface plates must not be damaged in the process. One particular problem is small, deep dead holes, which cannot be treated without the combined action of ultrasonic and slow rotation. HIGHCLEAN ULTRASONIC, which has been working in this field for many years, is in the vanguard in this and many other applications
Here is a typical system that we built for cleaning turned metal findings(ballpoint pen tips): It is important to realize that ballpoint pen tips treated with this system are only 9 mm long and 0.9 mm in diameter, and they have a dead hole. They are covered with turning oil and have tiny coil-like shavings stuck inside. After cleaning, the tips are assembled with ink refill. Any oil or shaving inadvertently remaining inside the tip would prevent the ballpoint pen from writing smoothly and flawlessly, causing it to fail the final inspection test.
Only the ultrasonic cleaning process has been able to ensure 100% results. In the beginning, the process used organic solvents (Trichloroethylene, chlorothene, perchloroethylene), but now safer and environmentally-friendly aqueous detergents (Safe Kleen 4053 For Cleaning Chemical is used which is totally bio-degradable chemical. The effective action of the ultrasonic is combined with a special rotation that ensures perfect results throughout the basket.
Here is the work cycle
- ULTRASONIC cleaning in warm alkaline detergent
- RINSING in cold running water
- Rinsing with ultrasonics in warm DEMINERALIZED water
- DRYING in warm pressure-ventilated air
Productivity is quite high,around 3-5 Kg. of material every 5 minutes (60 Kg. per hour).The system can be completely automatic and requires the presence of an operator 5 minutes each 20 minutes. Energy consumption is 12-14 kW, and the cost of detergent per work cycle is very low.
