Type1 One big cylinder from top moving down, multi-layer, multi cavity flash mould Press, Products with less density consistency leading to less stable performance, more noise and shorter life.

Type2 One big cylinder from bottom moving up, one big multi cavity mould, product’s SG consistency is better than Type1, but not ideal for optimal performance, noise and wear. 99% of so-called “Positive” in China use it. 

Type3 OEM Style Real Positive Technology. Four cylinder from bottom moving up, each cylinder works against one cavity, ensuring product’s SG very consistent for having optimal superior performance, noise free and long pad life. Friction One products are made by this technology.
