Electric Servo Drive Injection Molding Machine

J-AD Series, this next generation of compact and medium size injection molding machines from JSW continues to lead the injection molding machine industry. The J-AD ADvanced Series of machines offers even greater high-speed performance and increased precision, made possible by the industry's highest-speed* servo control circuit. This advanced technology, unique to JSW, has been accumulated over many years and results in injection molding expertise that is the envy of the industry. Faster and more accurate, the J-AD Series achieves the highest levels of productivity and reliability.

*As of 2004

  Promotion of product quality

  1. Incorporating a servo control circuit that boasts the industry's highest speed of 62 micro seconds Use of a high-speed servo control circuit in theJ-AD Series reduces scanning time to 1/16th of conventional controls and achieves an outstanding 62 micro seconds of scan time. It promotes product quality through a reduction in performance variation, such as holding transfer pressures.
  2. The resolution of the load cell amplifier for the injection pressure has been intensified five fold for more accurate back pressure control which helps insure stabilized precision molding.

  Remarkably improved operability and visibility

  1. A vertically arranged large 15 inch TFT color LCD screen. The controller rotates to provide the operator with a clear view of molding parameters.
  2. An illustration of the machine, in conjunction with operation mode keys and a touch screen, insures easy operation.
  3. Languages are selectable from Japanese, Chinese and English. Other languages(Korean, Spanish and French)are optional.
  4. Storage of molding conditions: 120 conditions can be stored in internal memory and 1,000 conditions stored in external USB memory.

  Improvements made for stepped-up productivity with larger molds

  1. The high-rigidity clamping unit enables the use of wider platens and achieves high-precision stabilized molding.
  2. Platen Parallelism and mold positioning accuracy is achieved by using a high efficiency platen support mechanism, with extra long platen guides.
  3. JSW's original 5-joint, internally folding toggle mechanism attains improved faster cycle molding.
  4. The stationary platen and the movable platen, consist of a box construction with reduced weight and increased rigidity, exerts a clamping force evenly distributed over the mold surface.
  5. The pre-tensioned tie bars promote durability and decrease vibration during the mold open/close action.
  6. The JSW injection compression molding feature enables the mold position to be controlled to accuracies over 10 times that of direct pressure molding. (Pat. # 1744469)

  High-speed quick-response injection

  1. High-speed quick-response injection with increased injection power.
    A JSW's original quick servo control circuit combined with a servo drive unit has achieved high-speed quick-response performance. Detail
  2. JSW's original injection control
    • IWCS control (Injection Weight and Cushion Stability) Detail

    IWCS control (Injection Weight and Cushion Stability)

    A patented control that stabilizes the density of the molten resin stored at the tip of the screw on every shot. This technology can minimize the variance in product weight. (Pat. # 3529771)

    • Electric-driven Soft Pack Servo Control Detail

    Electric-driven Soft Pack Servo Control

    The JSW patented control technology enables filling under optimum pressure while suppressing pressure peaks before holding pressure transfer during the injection process.
    This will prevent over-packing in thin-walled molding. (Pat. #. 1755568)

    Effect of Soft Pack Servo Control

    • Reduction of stress in molding
    • Elimination of flashes
    • Lessening variation in product weight
    • Lowering the clamping force (low-pressure molding)
    • Prevent mold damage
    • APC(Advanced Pressure Control) Detail

    APC (Advanced Pressure Control)

    The JSW patented control technology that holds down both over and under shooting in pressure control, during the injection process, enables higher-dimensional follow-up and response to the set pressure. (Pat. # 3168289)

    • Predicted control of metering Detail

    Predicted control of metering

    A control that smoothly stops the screw rotation and the back pressure, during the metering process, by predicting the metering beforehand. It decelerates the screw speed to an optimum value and decreases the screw back pressure smoothly.

    • Before-holding pressure deceleration control Detail
  3. Before-holding pressure deceleration control

    A control that decelerates the injection speed to optimum by predicting the holding pressure transfer position beforehand. During injection the inertial force the internal force is held down which is unique to electric servo drive injection molding machines.
    The control promotes stability of the holding pressure transfer pressure.

  Adapted for diversified lines of products on application

  1. A wide selection of injection modules and screws
  2. A wide selection of screws.
    Meeting versatile user needs, based upon the technology and provisions that JSW has accumulated over many years in the manufacture of plastic extruders that boast an impressive share of the world market.

  An advanced centralized monitoring system and a remote management system

  1. NET100 system and LINK10 system (Option)
    JSW network systems perform quality control and production control of injection molding machines and enables data to be exchanged with machines that are connected with in-shop LAN network. Up to 100 machines can be linked together on the NET100 system and up to 10 machines on the LINK10 system.
  2. Remote management system (Option)
    If you are in an Internet environment, you can monitor the machine condition, display the controller screens and change the controller settings from anywhere in the world via the NET100 system or the LINK10 system. Machines in a faraway overseas factory can be monitored over the Internet, which helps promote business efficiency.
