There were concerns such as 'scale buildup, narrowing of the cooling pipes, and poor cooling efficiency' and 'the need for regular cleaning, which is labor-intensive.' Therefore, we removed the calcium carbonate that had adhered inside the pipes using 'Control MF-2.' After that, by using the scale prevention agent 'Control PSV,' we suppressed the occurrence of scale. As a result, we were able to remove the scale without removing the pipes, and the use of the scale prevention agent significantly reduced the frequency of subsequent cleanings. [Case Overview] ■ Concerns - Scale buildup, narrowing of the cooling pipes, and poor cooling efficiency - The need for regular cleaning, which is labor-intensive *For more details, please refer to the PDF document or feel free to contact us.

Cleaner Systems with Control QA-2 During metal processing with water-soluble lubricants, metal soap waste is inevitably generated. Over time, this waste builds up inside machines and piping, causing contamination. Such deposits can reduce product quality, increase downtime, and shorten the lifespan of both tools and lubricants. With Control QA-2, maintenance becomes simple and effective. By adding it to the lubricant tank and circulating for 24 hours, accumulated waste in tanks and piping is dissolved and removed. The used solution can be disposed of directly as waste—no complicated procedures are required. Compared with conventional water or caustic cleaning, Control QA-2 delivers a far higher removal rate, helping manufacturers maintain cleaner systems, longer lubricant life, and more stable production. Case Summary Issues Metal soap waste generated during metal processing with water-soluble lubricants accumulates in machines and piping. This buildup leads to lower product quality and reduces the service life of tools and lubricants. For more details, please see the PDF or contact us for further information.
