Energy-Saving Performance of Electric Injection Molding Machines

Electric injection molding machines save much more energy than hydraulic injection molding machines due to the difference in power transmission efficiency and the fact that the motor is driven only for necessary operations. Other energy-saving effects include economic and environmental improvements due to a significant reduction in hydraulic oil consumption, economic improvements due to a significant reduction in cooling water, productivity improvements due to high-cycle molding, and reduction of "wasted" shots by stabilizing molding quality.

(Note) The energy-saving effects (shown below or above) vary depending on the shape of the molded product, resin, and molding conditions used by the customer. Please consult with us about the energy-saving effects that can be expected from your injection molding machine.

UBE Machinery's Toggle Type All Electric Injection Molding Machine with Outstanding Energy Saving Performance
UF Series, HH Series

UBE Machinery's UF and HH series toggle-type all-electric injection molding machines are all-electric machines that do not require electric power to maintain the clamping force, taking advantage of the toggle-type mold clamping mechanism, and offer outstanding energy-saving performance by significantly reducing energy consumption compared to hydraulic injection molding machines.

em III Series

UBE Machinery's 2-platen electric injection molding machine, em III series has further improved the pressure holding performance of the hydraulic system to significantly reduce energy consumption during mold clamping pressurizing, holding, and decompressing, which has been a problem for 2-platen electric injection molding machines, and has achieved energy-saving performance equivalent to that of toggle-type all-electric injection molding machines.

“Eco Barrel Cover” (Option) reduces heater power consumption

“Plasticizing” and “Heater” operation processes account for a large percentage of the power consumption of a molding machine. The "Eco Barrel Cover" (Barrel Heater Heat Insulation Cover) reduces the heat dissipation from the injection molding machine barrel to the atmosphere and improves energy efficiency when the barrel temperaturerises. This functional cover is custom-made by UBE Machinery with excellent safety, durability, and energy efficiency.

• Temperature stabilization by highly insulated materials
• Heater power reduced by 20% or more
• Reduced environmental impact

DIEPREST

The precision mold open/close control operation DIEPREST reduces mold clamping force through low-pressure molding using one of the DIEPREST functions, thereby downsizing the required molding machine and reducing the machine's operating energy.

SCS Molding (Sequential Cavity Separation)

This is UBE Machinery's control technology for efficiently molding multiple product groups on a single molding machine.SCS molding realizes energy savings by consolidating molding machines and auxiliary equipment and reducing the number of machines in operation.

Ultra-high mixing, dispersion screw

Ultra-high mixing, dispersing screw with color dispersing performance equivalent to that of mixing nozzles reduces energy loss in the setup and production processes.

1. (1) Reduction of plasticizing power by lowering back pressure and shortening measuring time
2. (2) Reduction of injection filling energy loss
3. (3) Shorter setup time and energy loss by reducing the number of purging times during setup

Power regeneration system

The braking energy of the drive motor used for mold opening/closing, plasticizing, and injection during deceleration is regenerated to the molding machine power supply, thereby reducing the drive energy loss of the molding machine.

MMX Series

Equipped with "Energy-Saving Pump Control System" that contributes to carbon neutrality

UBE Machinery's MMX series servo-hydraulic injection molding machines employ UBE's unique "energy-saving pump control system," which is different from conventional servo-hydraulic machines. The MMX series achieves both reduced energy consumption and powerful continuous molding operation, thereby reducing customers' production costs and improving productivity. The hydraulic pump control system, which is driven only when operation is required, significantly reduces power consumption compared to conventional hydraulic machines, contributing to carbon neutrality.
