High Speed Injection Moulding Machine
Dakumar 5H injection molding machine is developed based on our decade’s experience of offering customer injection molding service. Combine customer's feedback and many good contributory suggestions, our designer do all-around improvement of the machine design.
Dakumar 5H injection molding machine bring in advanced German technology, it is a new type hydrid injection machine, especially suitable for thinwall product. 5H means: High speed, High stability, High injection precision, High energy saving, High safety.
Dakumar 5H injection molding machine R&D
A. Injection fuel tank with single-cylinder injection, injection cylinders and the screw are at a straight line, without the problem of double cylinder synchronizing. At the same time, reducing the part quality, leads to the fast response of changing injection speed. With the MOOG servo valve control, it is more suitable for fast and accurate shot.
B. The high response ACC accumulator Design, the largest injection speed can reach 400MM/SEC to shorten the injection time to meet the diverse product requirements.
C. Melt by the servo direct drive motor, precise metering, energy saving and the formation of multi-loop control to save the molding time.
A. Mold plate by the finite element analysis, its feature of high rigidity and little deformation can protect mold and suitable for the institutional needs of the high rate of fire
B. Moving platen supported by rollers to reduce the friction coefficient and effectively reduce the resistance of mold opening and closing platen and increase the parallel of platen. Also protect the large column, mold and enhance its life.
C. Toggle designed through special software to the optima, to be rapid and stable
D. Increase the spacing of the mold platen, increase Min.& Max. Mould Thickness
E. The extra large column nut is designed with flexibility to reduce the shear force which the large column suffered , and enhance the life
A. High response servo-hydraulic system, compared with traditional standard pumps or variable displacement pump system, servo-hydraulic system combines the fast stepless speed regulation characteristics of servo motor and the hydraulic pump’s feature that independently regulate the hydromantic which leading precision energy-saving, energy saving up to 80% .
B. High-precision, high response of the PID algorithm module make the system pressure very stable. The pressure fluctuation is less than 0.5bar, and with high repeatability precision. Servo motor only needs 20/s from rest to reach the rated speed. Pressure and flow velocity response is only 0.03s or so, not only can significantly improve repeatability precision, and the open mold position accuracy can reach 0.5mm, ensure that the mold performs better with robot
To increase the pump’s output quantity by increasing the motor speed and improve the machine’s operation speed.
C. Short molding cycle and more efficient. As a result of a servo motor, the start and stop of each action need less time, and the cancel the proportional valve, so that reduce the hydraulic leakage.
D. Soft-start mode, will not impact on the power grid to avoid contamination.
E. Servo-hydraulic system with high efficiency can effectively prevent the oil temperature rise, warming to reduce, thereby reducing the replacement rate of hydraulic oil.
F. Servo motor and gear pump of the power system because of its nature, low noise, and improve the working environment.
G. By-pass returning oil filter, clean the impurities of the hydraulic oil to ensure the service life of hydraulic components.
H. Multi-loop hydraulic system, multiple actions proceed simultaneously, shorten production cycles, improve production efficiency.
I. Multi-stage pressure control, more precise measurement of melt.
J. Selection of imported oil seals, to ensure no fuel tank leakage, and more stable.
Assorting different configurations according to customer demand for the product, to enhance cost-effective
