Glass wool mechanism in purging



Introduction of ecomaru


Ecomaru, a series of purging compound made of a resin filled with glass wool (GW), was first introduced in Japan in 2018 from the maker Nanodax (Tokyo, Japan).  Yasukawa is the first distributor appointed by Nanodax.  


Ecomaru cleans strongly and thoroughly contamination (black specks (carbides) and color) inside mold injection machines, with less waste and less odor. 


In many use cases, because of its unprecedented performance,  ecomaru is even replacing disassemble-machine-to-clean process (conditions may apply).   In such cases, the time to complete the cleaning work had decreased from two to three days to merely an hour.


We are proud of ecomaru being an upcycled product from glass wool and contributing to SDGs created by the United Nations. 


Free ecomaru samples are available to overseas markets, as well.
