When the manual hole puncher DJP18012 was first put into the market in 2011, it is quickly spread in the sign making field. Chinese Sign makers found an ideal tool to instead of electric drills to make holes on stainless steel/aluminum/galvanized metal tape. It gets popular in sign makers soon.
Lacking of brand protect awareness, we didn’t apply for patent for the hole puncher. Soon many kinds of imitations of our manual hole punchers were seen in the market. With similar shapes but bad quality, the imitations gradually ruined the market. We decided to make a new type manual hole puncher in 2016. After 2 years test & hard working, our new model hole puncher DJP18050 was put into mass production in 2018.
