Chengdu Hangfa Hydraulic Engineering Co., Ltd was founded in 2002, which is one of the earliest enterprises in Southwest China to engage in the R&D and manufacturing of hydraulic presses, hydraulic systems and non-standard electromechanical equipment. So far, the company has supplied more than 5000 sets of hydraulic equipment to the market. The company developed and manufactured the first domestic “lithium belt extruder”, involved in the manufacture of long-lasting lithium batteries, breaking the monopoly of foreign equipment. ADF's lithium belt extruder has been widely praised since its launch, and has been updated to the eighth generation, which can produce lithium belts with a maximum width of 600mm and a maximum thickness of 0.005mm, and has realized a 90% market share in China.
