Power consumption display

Visualization of power consumption promotes energy saving activity. Either integrated total power consumption from a preset point or hourly consumption can be displayed by switching. In addition, the consumed power can be displayed in the desired unit such as JP¥, US$ or emitted amount of CO2.

Optimum mold clamping is realized

Proven technology, “V-clamp” mold clamping mechanism.

Carrying the fruit of the joint development with academic sector, the mold clamping device efficiently delivers the clamping force to the mold in even distribution. The clamping mechanism can be flexibly adapted to large molds in complex structure. The large model has adopted a clamping mechanism having higher rigidity. The V-clamp mold clamping mechanism, which has been standard since the Si-IV series, effectively delivers the clamping force to the center of the mold owing to its “center press effect.” And the high rigidity and yet slim mold mounting plates, which are also time-proven, evenly distributes the clamping force over the entire mold. Well-balanced even distribution of clamping force can be maintained without applying a clamping force beyond necessity.

Easier maintenance and improved eco-efficiency

Reflecting desires from users, the Si-6 series is a practically easy machine to maintain. In addition, energy-efficiency and eco-friendliness are greatly increased.

Light weight splitable cover

The light weight and splitable cover design have eased removing or installing work of covers at the screw access area and the toggle area. This cover design facilitates maintenance work including screw maintenance work and toggle cleaning work.

These covers also secure further safety.

Totally automatic grease-lubrication system as standard

Si-280-6S and more

The Si-6S series is equipped with the totally automatic grease-lubrication system, as standard, that covers not only ball screws, toggles, tie-bars and guide bars, but also all other greasing points that were previously optional.

Widely opening safety door

The Si-6S series is equipped with the widely opening safety door, which had been adopted on the previous Si-6 series. The widely opening safety door facilitates the mold changing work without taking unreasonable attitude, contributing to reduced work time and higher safety.

High degree of serviceability and safety, essential to the machine, are provided

The fully automated lubrication control and the wide opening stroke safety door are among the features of the Si-6S series, which facilitate maintenance work and secure greater safety. These features reflect on comments and suggestions from customers who have been using our machines

Power consumption display

Visualization of power consumption promotes energy saving activity. Either integrated total power consumption from a preset point or hourly consumption can be displayed by switching. In addition, the consumed power can be displayed in the desired unit such as JP¥, US$ or emitted amount of CO2.

With standard, high pressure, high speed, large volume and small volume injection units.

To cope with injection at an increasingly high speed and high pressure, the Si-6S series have a variety of injection units from large volume to small volume, so that the Si-6S series can address the demands from each customer. The injection controlling technology, utilizing accumulated expertise, realizes high precision injection, thus contributing to high molding stability and productivity.

Wide variety of injection units

The Si-6S series has newly added K750E high speed injection unit which achieves a maximum injection speed of 250 mm/s, 138% faster than that of the standard K600E. And the models of 680-ton or larger in clamping force can accommodate a one-size larger injection unit compared with the previous series. With ‘standard,’ ‘high pressure,’ ‘high speed,’ ‘large volume,’ and ‘small volume’ injection units, the Si-6S series can cope with various needs from each customer.

Increased injection pressure

The increased rigidity of the injection unit allows higher injection pressures to be set.

And the double nozzle-touch rods structure prevents the inclination of the stationary mold mounting plate.
