We utilize a 100W JPT pulsed cleaning laser to efficiently remove a thin layer of rust (ranging from 0.5 to 1.5 μm) from the surface of our customers’ valves. These valves are manufactured from pig iron, a material that rapidly develops a thin gray oxide layer upon exposure to air before gradually transitioning into rust. To address this issue, we previously designed a customized ultrasonic vibratory cleaning line for the customer, which included the hanger conveyor system seen here. However, due to the high power consumption and significant water usage associated with ultrasonic cleaning, the customer decided to transition to a more efficient and eco-friendly pulsed laser cleaning solution.

Last month, the customer invited us to conduct an on-site sample cleaning test to evaluate the performance of our laser systems. We provided three options: 100W, 200W, and 300W handheld pulsed laser cleaners. After thorough testing, the 100W model was selected as the most cost-effective solution for their needs. While the 200W model offers a slight improvement in cleaning speed, the difference was not substantial enough to justify the higher cost for such thin rust layers. The 300W model, on the other hand, cleans 50% faster but comes with a price increase of over 50%, making it less economical for the customer’s current requirements.

To further enhance efficiency, we also proposed automated and semi-automated cleaning solutions that could integrate with the existing boom and pneumatic suction cup rotators on their production line. However, given the relatively low efficiency demands for cleaning outside the warehouse, the customer has postponed adopting these advanced solutions for now. That said, we remain open to future retrofitting opportunities should their production needs expand or business conditions improve.

If your operations involve similar rust removal challenges—whether for valves, machinery, or other metal components—we would be happy to assess your requirements and recommend the most suitable laser cleaning solution.
