Electric Servomotor Driven Plastic Injection Molding Machine, the Si-7 Series

The new "SYSTEM 800 SE" control system is designed to enhance information integration and convenience. Its operation unit features an 18.5-inch wide-color LCD HMI (Human-Machine Interface) with a capacitive multi-touch panel, combining a premium feel with smartphone-like operability. Its key features are reflected in four aspects: "Visibility," "Functionality," "Convenience," and "Maintainability."

• Visibility: Improved in every detail, such as making the on-screen calculator larger and easier to use, as well as enabling split-screen monitor display.
• Functionality: Equipped with various molding drive modes that enable molding similar to specialized machines.
• Convenience: Comes standard with the well-regarded meltcon®. Additionally, it features a check ring wear diagnostic function and an integrated operation management function for peripheral equipment.
• Maintainability: It is possible to record the maintenance performed on the machine itself.

The viscosity of the resin is measured and quantified using meltcon®. Based on the quantified data, wear amount is determined using a proprietary analysis process. This not only helps in identifying the optimal maintenance timing but also aids in production management.

The S-HIN screw is developed as a more versatile screw based on the performance of the SAG screw. We have improved plasticizing capability to accommodate a wider range of resins while suppressing breakup, an instability phenomenon during plasticization, and achieving plasticization stability.

• See "TOYO's Unique Plasticizing Items."

By expanding the daylight and increasing the tie-bar spacing, the flexibility for mounting molds has been enhanced. The increased space also provides more room for considering mold changeover devices, contributing to improved production efficiency.

High precision, high rigidity mold clamping mechanism

The models with increased die height and tie-bar spacing are listed above.

We provide machines that meet global safety and reliability standards.

• An electromagnetic lock switch (mechanical lock type) has been added to the operator-side safety door.
• The safety circuit has been reinforced by adding a safety relay unit and implementing power cutoff for the servo motor through the STO function of the servo amplifier.
• We enhanced the information included in the Instruction Manual.
