New control unit SYSTEM 500

• >> Pursuing greater quality and consistency in molded products
• ・High-speed, highly accurate injection motion control
  Built-in high-performance CPU delivers the fastest class control speed (Five times that of conventional systems *) in the industry, greatly decreasing variations at“change points”, such as the injection/holding pressure switching position, time and pressure, to improve the quality of molded products.
  *: Comparisons with a controller of Si-IV series 2009 model.

• ・Built-in high-performance digital load cell
  A high-performance digital load cell and low-friction guide mechanism improves the plastication pressure resolution and enables high-precision plasticity measurement.

• >> Digitized molding technology and expertise
• ・V-mode injection control (Adjustable response function)
  In addition to multi-step speed control and speed slope control, an automatic acceleration control function is provided for injection and for mold opening and closing.
  With the V mode (acceleration and deceleration mode) added, conventionally complicated parameter settings are easy to make. (Three modes available for injection and mold opening/closing settings)

• ・Just Pack control (High-precision holding pressure control)
  By providing precise holding process control right up to completion of the first injection process, smoother melt filling can be achieved compared with conventional control. This control suppresses burrs and minimizes the residual stress that causes warping of moldings.

• ・Molding navigation function (Molding condition input support and diagnosis function)
  This navigation function guides an operator step-by-step along the setting process of basic molding parameters based on the basic setting principle. This function is helpful for novice operators to learn the settings and for old pro alike operators to recall the basic setting method.

Newly designed injection unit

• ・For thin wall and high-precision molding
  The addition of “high-pressure” specs results in a completely new lineup of injection units

Inherited technology

• ・Developed through academic-industrial cooperation The "V-Clamp" for optimal mold clamping.
• ・The SRC-II metering system ensures uniform metering density.
• ・The SRC-III metering system prevents melt backflow.

Complies with global safety standards

• ・Japan(K1001:The Japan Society of Industrial Machinery Manufacturers)/China(GB22530: National Standard)/Europe(CE Mark)/North America(ANSI/SPI)/South Korea(KC Mark)
  Safety specifications are available to meet the safety standards for each country.

TOYO's Built‐in Servo System BD100 / GD620

Built‐in Servo System

The BD and GD series injection units employ TOYO's BUILT-IN SERVO SYSTEM that directly connects the injection ball screw and servomotor, minimizes transmission energy loss by simplifying the mechanism structure, and achieves high torque from a compact motor by eliminating wasted inertia.
Designed with an emphasis on high acceleration and deceleration performance, on top of increased injection speed, this BUILT-IN SERVO SYSTEM demonstrates its effect in molding, for example, super-small capacity, small, precision parts, such as those represented by the fine pitch connector, and light guides for the LCD displays for monitors and mobile PCs when using medium and large injection molding machines.

Twice The Acceleration Performance

The adoption of a BUILT-IN SERVO SYSTEM enabled 10G acceleration* to be achieved, about twice that of a conventional high-speed unit, as well as improving maximum injection pressure by 17% (*) compared with the same conventional model. In addition, a high 800 mm/s* maximum injection speed was also realized.

New High-Speed, High-Precision Control System

These injection units incorporate a high response control system that enables high acceleration and deceleration motion control. Compared with conventional control system, communication speed is increased tenfold while scan time is cut in half, allowing the status of the servomotor to be monitored closer to real time.
The volume of communication information that can be transmitted has been increased dramatically, making it now possible to change parameters even while the machine is in operation.
