1.The pressure of front and back pressure heads balances automatically through hydraulic connecting vessel, which makes front and back press forces homogeneous.The device can beat angle automatically in convenience of taking shoes. 2.pressing blocks of the same shoes shape carry out tighl wall side presssing on shoe mold. Each block has independent cylinder motion. which makes the binding of shoe edge best. 3.The lift of front and rear compacting oil cylinder s is adjustable and fit for shoes of any size. 4.Each motion of the machine has adjustable pressure function.Secondary pressure sole-pressing makes sole strongly bond with shoe cover.
