[Case Study] Introduction of NR-1100 Reduces In-Process Defects by Up to 90%

Introduction of NR-1100 reduces in-process defects by up to 90%! A case that also achieved stable quality.

We would like to introduce a case study of a customer who implemented the "NR Series." The company manufactures approximately 2,000 types of injection-molded products, primarily focusing on lighting fixture components for automobiles and ships, using 40 injection molding machines. They faced challenges such as "process defects occurring for several minutes to over ten minutes during mold changes." To address this, they tested multiple models that allow for the cleaning of water pipes without disassembling the molds. They decided to implement the "NR-1100," which demonstrates high cleaning capability using only water and air, without chemicals, and excels in environmental adaptability. As a result, they successfully transitioned from "reactive maintenance," which addresses issues after they occur, to "preventive maintenance," which involves regularly cleaning the water pipes. This change led to a reduction of process defects after mold changes by up to 90%. [Problems] - There were many process defects during startup due to dirt in the cooling water pipes of the molds. - Disassembling and reassembling the molds took time, preventing thorough cleaning of many molds. - The disassembly and reassembly of molds placed a heavy burden on workers, leading to a "reactive maintenance" approach where cleaning was done only after problems occurred. *For more details, please refer to the PDF document or feel free to contact us.*
