Horizontal Plastic Injection Mould Machine
Characteristics of Injection Unit
Optimum designed screw with large L/D ratio enjoys features of wide application, good plasticization and high efficiency.
Oil cylinder base moves on the foundation, the structure is individualistic. The injection device is connected with union stem of front mould plate by ball, regulated easily and reliably.

The thin-walled products demand, combined with the high-speed thin wall injection machine design the development of new technology, the machine series storage stability, its unique injection system, hydraulic system, computer control system, locking system with high strength and wear resistance, fast, so that the properties of high speed, fully meet the requirements for high voltage. The empty short cycle time (2.6 seconds -3.6 seconds) injection of high pressure (up to 240MPA) injection speed (up to 600MM/S),fully qualified for the production of thin-walled products,especially suitable for the production of thin wall (0.4MM)tableware and other containers.
A new circuit of electric control system, multiple sets ofproportional control, computer controller dedicated, shorten the whole machine cycle time.
The injection unit accumulator, the basic injection 5 times faster, especially suitable for the production of thin-walled products.
Proportional valve control installation precision mold parts,reduce the template reaction time, improve the productioncycle efficiency, and to fine protective effect on mold.
High wear resistance and high lubricity sleeve shaft lockingconnecting rod structure to ensure the service life
Injection molding machine, injection molding machine or injection machine. It is the main forming equipment plastic products, thermoplastic or thermosetting plastics using plastic molding into various shapes. Divided into vertical, horizontal, all electric. The function of heating plastic injection, high voltage is applied to the molten plastic, so that the injection and full of mold cavity
