Machine Features:

The screw adopts high potency melt to make sure the material well mixed.

Adopt frequency control of motor system to reduce the power consumption.

Adopt horizontal movement frame to improve stability and speed.

The oil cylinder is in the center of the mold board, uniform stress for quality products and increase life time.

High stench guild rod controller the mold open and clamp, to enhance the steadily and high efficiency.

The extrusion head use spreader or screw type to well mixed the thickness and easy to change different color.

Advanced design to eliminate the melt material degrade in the runner, to avoid the perform draw-down and the welding line.

The precise time control system assured good quality, suitable weight and reduces production cycle.

Freely to move the extrusion foundation backward or forward to make the exchange of  the mold easy.

Multi-function bottom blowing type for shaped products.

The mechanical arm can take out the product automatically.


Double stations and linear guide movement, high intensity stainless steel mould platens, driven by hydraulic pressure, designed and analyzed by finite element aided software, ensure big clamping force, no expansion of mold.
High span central supporting mould platens make the movement stable and less wearing; central clamping with large mold open stroke ensures the even clamping force and keeps the mold platens in deformable.
Specially designed screw with high L/D ratio insures good plasticizing and stable extrusion; high precision and no part line die head guarantees customers’ top-quality requirement.
Multi-screw & multi-die head can be adopted to improve the quality of the product and lower down the cost of material.
Famous brand of vector inverter in high pulling torque, complied with special extrusion hardened reducer, can operate in stable, durable, and low noise state.
All hydraulic parts are from Yuken (Japan) . Pressure & proportional control are set by PLC, which ensures the stable operation ; Mold movement is controlled by special speed limited valves, ensuring precise position and non-striking.
Parts of pneumatic system are imported from FESTO (Germany), SMC (Japan), etc, which are top brands in the world. These make sure the operation of machine reliably and accurately; the air circulation is large while the leakage is very small.
High speed Siemens (Germany) PLC with multiple language touch screen, easy-access menu display, is easy to control and operate.
Schneider (France) touchless sensors and switches are adopted, which are dependable and in low heat, & prolonged life.
Multiple-way PID controlled temperature heating is precise and stable. . Parison controller is optional to reach high quality products and reduce cost.
Fully automatic operation can be achieved by optional equipments like auto-deflashing, rotary trimming device, or separated rotary trimming equipment
