Bakelite Injection Molding Machine 228B Send Enquiry

1.    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.

2.    Oil cooling device in the Bakelite screw & barrel ensures the precision of the temperature control.

3.    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.

4.    Upgraded size of the hydraulic motor improves the injection rate and achieves a better plasticization.

5.    Specially designed heat resolution plate in the mould platens to meet the Bakelite mold temperature requirements.

6.    Two sets of mold temperature control interface, controlled by the PLCwith high precision.

7.    Using high-precision linear transducer to achieve high-precision position control. Position setting precision can reach 0.1mm.

8.    Automatic mold adjustment function can directly input locking pressure and automatically complete mold thickness adjusting by PLC
