Hydraulic Die-casting Machine：The BD-V7EX Series

"By adopting proprietary hydraulic technology, the THRV System, we have improved high-speed acceleration performance compared to conventional models.
The shorter filling time allows molten metal to fill the mold cavity before solidifying on the mold surface, effectively minimizing flow lines, as evidenced by the improved appearance of the cast products.
※THRV System：TOYO High Response Valve System

Effect: Reduction of defects in thin-wall sections

High-speed filling allows molten metal to reach thin-walled sections before solidification, preventing issues such as insufficient melt flow and cold wrinkles.

Effect: Dispersion and Refinement of Porosity

The molten metal passing through the gate becomes atomized by the rapid acceleration of injection, which improves die-casting quality by finely dispersing air bubbles that can cause casting porosities.

Comparison of castings appearance

Shorter filling times allow the molten metal to fill before it solidifies on the surface of the die, thereby reducing the cold wrinkles.

The SYSTEM700EX has been developed from four perspectives - visibility, functionality, maintainability and convenience - to reflect user feedback and improve functionality as a goal.

Our proprietary injection control system allows selection between meter-in and meter-out modes.

Laminar Flow Die-casting

Deceleration effect (High speed: 4.0 m/s)

The tie-bar pull-out device on the stationary die plate side adopts a nut splitting system. This significantly reduces the operating time compared to the conventional nut rotation system, enabling smoother setup changes.

By controlling the pump rotation with a servo motor, energy efficiency is improved, reducing running costs.

The high-precision, high-rigidity die clamping mechanism, which accommodates dies for one rank larger machine, minimizes deflection. By optimizing the stationary and movable die plates' shapes, it effectively reduces burr formation.

High precision, high rigidity die clamping mechanism accommodates the dies for one class larger machine.

• A high-precision, high-rigidity clamping device with increased rigidity thanks to a guide bar mechanism.
• The center press mechanism minimizes deflection at the die mounting area.
• By further lowering the lower injection position, it is possible to accommodate one class larger dies.

Ideally-configurated stationary and movable die plates reduce their deflection.

• Assisted with CAE analysis, optimally designed die plates minimize their deflection.
• By generating uniform clamping force over the mold parting surface, optimal casting is achieved.
• It minimizes deflection and effectively reduces burr formation.
