Foxnum all electric injection molding machine
The kernel technique for Foxnum all electric injection molding machine is the controller, servo drives and servo motors. Foxnum technology has spent so many years on developing this unique technology. Right now Foxnum technology can integrate different size’s motors in different tons of injection molding machine to meet customers’ various demands. Whole series of all electric injection molding machines are from 50 tons to 350 tons. (450 tons will be ready within end of 2013) Foxnum technology can offer high stability, high precision, high injection speed, and high injection pressure model to help users on all kinds of plastic injection productions.
Foxnum all-electric injection molding machine adopts high-powered and high-efficiency servo motor. Because this machine is run by the servo motors, and servo motor only requires power when in operation. Traditional model of hydraulic injection molding machine has to run nonstop, 24 hrs, and 365 days. That’s why the all electric injection molding machine can save more energy than the traditional hydraulic one. This new-generation machine also does not need extra electricity for cooling water(hydraulic oil cooling), nor the consumption of hydraulic oil. All-electric injection molding machine can save 50%~70% than hydraulic injection molding machine.
Foxnum all-electric injection molding machine is a high speed machine, therefore the production capacity can be increased more than 20%. With such great performance on precision control and energy saving, Foxnum all-electric injection molding machine is your best helper on reducing production costs.
All axes of Foxnum all-electric injection molding machine are run by high-efficiency servo motors. Multi-axis of this machine can be executed synchronously. When cooling is finished, this machine can start to open mold and eject in no time. Perfect and smooth processing steps can help to reduce product cycle time. With a low-impedance, low inertia innovative design motor, Foxnum all-electric injection molding machine can speed up the injection speed up to 350mm, V/P switch accuracy can reach 0.01mm, this machine can absolutely provide a variety of plastic products manufacturing.
After passing noise test, we know that Foxnum all-electric injection molding machine has very small running sound. Unlike traditional hydraulic injection molding machine, Foxnum all-electric injection molding machine does not have to continue to run all the time to drive hydraulic unit. It was run by servo motors, so the vibration and sound will be much smaller. The machine runs quiet, low-decibel, and can reduce noise pollution to protect factory operators from hearing damage. The most important of all is that all-electric injection molding machine can save soundproofing cost in the workshop.
This machine does not have oil spilling or oil pollution problem. It can make workshop clean to meet 6S demand. Easy maintenance, especially for clean room.
When the plastic materials were injected into the mold cavity, there will have a strong power to expand the mold, therefore the clamping unit must provide sufficient clamping force to hold on the mold. Foxnum all-electric injection molding machine is a toggle type machine. It has larger tie-bar and toggle size, so the mechanical life will be much longer. It can also lock the platen firmly. Open/close mold positioning accuracy is smaller than 0.01mm. According to finite element stress analysis, we make the best design of high rigidity and low deformation platen and bed platform, it can offer high precision clamping force.
Because the characteristics of injection molding machine are totally different from CNC machine tools, universal motors cannot be applied well on the injection machine. We Foxnum Technology have developed a dedicated high-powered servo drive and servo motor specifically for all electric injection molding machine. For the injection axis, we use of low inertia and high torque motor. For feeding axis, we use of low speed and high torque motor. For eject axis, we use high speed with brake motor. For clamping axis, we use high speed and overloading motor. Our servo drive is from 3kw to 55kw. We can also do different configuration of servo drives and motors to meet customers’ different requests. On the servo motors, we choose built-in magnet structure to make this motor have strong rigidity and have longer life. (Other suppliers only use surface magnet mounting method) Special air tunnel design let the motor have better heat dissipation and smaller temperature rise. The most powerful thing is that we can also provide three times over-loading motor design and three times linear torque design to make it have stronger power.
In addition, we choose the best German-made mechanical encoder to be our ABS motor response device. It is different from other makers’ encoder. Our mechanical encoder does not need batteries to memorize the position. It has precise feedback, and can be up to 2 million high-resolution per revolution, its precision numerical computation can be up to 0.1μm.
