Today, Getsaf get the Patent for the new invent on the hose process. At the moment, most of Chinese hose factory adopt the pp mandrel for producing the hose. But the mandrel is hollow. When we use this kind of hollow pp mandrel to produce the hydraulic hose, it will bring a lot of problems. 1. the hollow pp mandrel is easily be expanded under the steam high temperature. so the tolerance of inner diameter of the hose will be very big. 2. the water will be easily put into the hollow hole, when sulfur the hose under the steam, the water will easily to go out from the inner rubber. So it cuase pin hole.
Getsaf adopt the pp mandrel without any hole, it is not hollow, but solid. This invent is to protect us to make good hose without pinhole.
