● specially designed screw & barrel for bakelite, which is made by high strength bi-metallic steel with special treatment, with the characteristic of good corrosion resistance & good abrasion resistance.
● oil cooling device in the bakelite screw & barrel ensures the precision of the temperature control.
● according to bakelite material features, the machine can exhaust while opening the mold.
● it can be converted into thermoplastic injection molding machine after replacing the screw and barrel group.
● upgraded size of the hydraulic motor improves the injection rate and achieves a better plasticization.
● specially designed heat resolution plate in the mould platens to meet the bakelite mold temperature requirements.
● two sets of mold temperature control interface, controlled by the plcwith high precision.
● using high-precision linear transducer to achieve high-precision position control. position setting precision can reach 0.1mm.
● automatic mold adjustment function can directly input locking pressure and automatically complete mold thickness adjusting by plc.
