Introducing the World's First 4,000-ton Electric Injection Molding Machine!

The industry's first ultra-large electric injection molding machine featuring the world's highest clamping force of 4,000 metric tons is now part of our standard lineup.

  We are now launching a two-platen, ultra-large electric injection molding machine with a clamping force of 4,000 tons.

  With the rapid global shift toward electric vehicles, there is an increasing demand for lighter components to extend driving range. Target products for the 4,000-ton class clamping force include exterior parts such as bumpers and tailgates, as well as the conversion of electric vehicle battery cases to plastic. Demand is growing from automobile-related manufacturers both in Japan and overseas. In the United States, molding machines of this class are widely used in agricultural/ industrial machinery, general merchandise, and home appliance industries, apart from the automotive industry.

Currently, hydraulic systems (which use hydraulic pressure as the drive source) are the mainstream in the 4,000-ton injection molding machine market, but hydraulic systems have the following issues:

  Therefore, in order to solve these issues with hydraulic systems, we have adopted an electric system, which allows us to achieve high productivity, energy efficiency, and high quality, and differentiates us from other companies with our unique long-life, robust design.

• Model name: J4000F-22000H
• Clamping force: 4000 metric tons (4,400 US tons)

• Maximum injection volume: 22,000cm³
  ⇒ Approx. 18.6 kg in PP equivalent

[Improved productivity]

• The industry's fastest dry cycle improves productivity by 10% compared to the latest hydraulic systems.

➡ Electric servo motor drive and our own unique mechanism

• Because it is an electric type, there is little variation and the short start-up time, improving the operating rate.

[Energy saving and reduced running costs]

• Compared to hydraulic systems, power consumption is reduced by 15-20%, cooling water consumption is reduced by 50%, and hydraulic oil consumption is reduced by 70%.

➡ Annual CO₂emissions reduced by 15-20%　
*Compared to hydraulic systems

➡ Annual running costs can be reduced by more than 20%

[Space saving]

• The shortest machine length in the industry: 17.4m

➡ 12% shorter than other companies' latest hydraulic systems

[Long life and robust design]

• Inheriting the design philosophy that we have cultivated over many years, ensures long-term reliable operation.

① High rigidity mold platen

⇒Like a car bumper, it is short vertically and long horizontally (which is disadvantageous for molding machines)
The mold also has sufficient rigidity to prevent molding defects in the molded product.

② High-performance movable platen support mechanism

⇒Large-diameter, wide support rollers maintain platen precision over extended periods.
*Our proprietary technology

③ High rigidity clamping bed

⇒The ladder frame structure keeps the bed level for a long life machine.
