B50-2L extrusion blow molding machine
Technical characteristics:
Single (double)-station, single head, fully automatic extrusion blow molding machine, with crank-arm clamping system.
Suitable for 5ML-2L PE, PP bottle, like cosmetic container, beverage container.
Suitable to connect with different automation equipment, reduce labor costs and increase production efficiency.
The die head can be changed to double-die, three-die and four-die, to produce smaller capacity hollow products with multiple specifications, increase production and reduce energy cosumption.
Also can add the liquid line function to enrich the product line.
B50-2L extrusion blow molding machine description
PLC+touch screen, making the operation easy. Automatic malfunction alarm with selfdiagnosis, making the malfunction clear at a glance. Center input die head, eliminating the knit line completely and making it easy to change the material and color.
Double linear rolling motion guider in moving, opening and closing mold, making the clamping force equally distributed, so the cut is smoother. Control the hydraulic system with imported proportional valve, ensuring the action steady, accurate and energy saving.
High speed and efficient plasticizing system, mixing well and ensuring the produce purity
