The machine is versatile in that it can work with a variety of materials including PE, PP, PVC, PA, PC, PS, and EVA, ensuring an optimal manufacturing process.

This machine offers a wide range of applications, from small containers to large hollow products, catering to different industrial needs effectively. The MP plastic blow molding machine stands out for its ability to deliver exceptional performance and precision in producing plastic products with complex shapes and sizes. Its versatility in material compatibility allows for flexibility in manufacturing various plastic items with different specifications and requirements.

Features:

a) Extruding device adopts variable frequency motor which can satisfy the requirements of rotation change of screw during blowing process. Screw with big slenderness ratio can be used to process many kinds of materials and has strong plasticizing ability, high production and low energy consumption. The barrel adopts resistance heater which is controlled by computer and heats quickly, stably and equably.

b) By installing different head in combined extrusion system between two extrusion machines, they can blow products with view strip line or double layers.

c) Mould clamping device adopts vertical compression, three pilot post, big beam arm and linear guider, cylinder spindle and double working position. Mould moves fast and stably.

d) Improved design of hydraulic oil loop. Power saving, rapid and stable.

e) Installation and maintenance of hydraulic elements are convenient. Equipped with removable and mobilizable oil tank.

f) The whole machine is controlled by computer. The hydraulic system adopts double proportional control. This machine has fault automatic alarm, reliable operation, high automation and data memory of 40 sets of moulds.

g) Three operation modes-“Manual”, “Semi Auto”, “Full Auto”, are allowed to select.

h) Safety door adopts electric and mechanical safety devices( no mould closing happens when safety door opens) which make operation safe and reliable.

i) This machine has two blowing functions of straight cutting and oblique cutting
