SCJC230×2 Double-layer Co-extrude Plastics Blow Moulding Machine
?The machine consists of frame, extruder, co-extrude die head, moulding machine, blow unit, mechanical hand, safe guards, electric, hydraulic and pneumatic systems, automatic loading machine mainly. It is suitable for producing double-layer compound blow containers made of heavy molecular weight PE.
Specifications and parameters of it are as follows:
?.Extruder:
