In order to realize the “New 3S” with high-productivity and low environmental impact die-casting machines, we have developed the R series die-casting machines,the world's first die-casting machines equipped with an electric clamping mechanism as standard equipment.
This time, the R series has been further evolved and minor-changed to the R2 series.

Line-up

Based on the “New 3S” concept, the R2 series features many improvements that
combine high productivity with reduced environmental impact, including improved workability.

The R2 series offers 250ton, 400ton, 500ton, 650ton, and 850ton die locking force lineups.

SAVE TIME

Die locking force UP

The conventional DC350R/DC800R series has been upgraded to DC400R2/DC850R2 in terms of die locking force clamping force.

DC350R is now 400R2 with 14% higher die locking force.
DC800R is now DC850R2 with 6% higher die locking force.

Expect quality improvement in a wide variety of products, both thick and thin-walled

The die mounting relationship between DC350R and DC400R2 is the same.

Existing molds can take advantage of difference in die locking force

Existing molds can take advantage of difference in die locking force.

Lightweight pistons due to increased speed and pressure100G/10m/s

Highly controlled speed to suppress burrs. Reduces defective products.

The injection piston is made lighter and more controllable by using a two-cylinder system: a speed cylinder for speed control and an intensification cylinder for intensification control.

Injection Structure Features

• Conventional 2-cylinder system
• Meter-out speed control
• High flow rate, high response servo-hydraulic valve
• Meter-in intensification control
• V-P switching control

Reduced pressurizing time up to 9.6msec

Fluctuations in molten metal supply volume are controlled by a new intensification start control.
Shortens pressurizing time, improves safety, and stabilizes internal quality.

Reduces pressurizing time up to 9.6 msec with new intensification start control.
Speed control is added to the conventional position start control, and the pressurizing start timing changes according to the change in molten metal supply. The quality is stable even when used at high speeds or deceleration.

Improved pressurizing performance (reduced pressure boosting time)

Short-time intensification improves internal quality

The shorter intensification time, the better the internal quality, so a stable short-time intensification is important.
