We would like to introduce a case study on the use of "Asaclean," which blocks oxygen and suppresses thermal degradation due to its excellent thermal stability. Inside the resin molding machine that is stopped, the residual resin deteriorates due to residual heat and oxygen in the air. As a result, problems such as foreign matter contamination during startup are more likely to occur. By sealing the machine with Asaclean, which has excellent thermal stability, it is possible to eliminate this potential issue. [Customer Feedback] ■ During machine downtime, we perform cleaning with Asaclean "U," sealing with "IMX," and cleaning again with "UF2." The startup after holidays has been completed in less than half the time compared to before, and we are grateful for that. ■ We conduct regular cleaning every two weeks with Asaclean "newEX" and "newUP," and seal during long-term shutdowns (during holidays) with "newUP," reducing defects from 3% to 0.3% after the shutdown. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study on the use of "Asaclean," which serves as a savior in reviving high-productivity molding sites. When resin molding machines operate for extended periods, the resin that accumulates inside the machine deteriorates, and if it contaminates the molded products, it results in foreign matter defects. This not only significantly impacts yield but also requires disassembly and cleaning, which halts production and leads to substantial opportunity losses. Our product effectively removes foreign matter with its powerful cleaning ability, fundamentally solving the issue of foreign matter generation. Therefore, it resets the interior of the molding machine to a clean state without the need for cumbersome and time-consuming disassembly and cleaning. [Customer Feedback] ■ Previously, changing colors, especially cleaning Cyanine Blue, required about 10 tons of LD, HD, and others, taking nearly 35 hours. However, with Asaclean, cleaning can be done with 300kg to 400kg of usage in about 8 hours, significantly reducing raw material loss and time. *For more details, please download the PDF or feel free to contact us.
