V-LINE®

Plasticization & injection units which realize stable and high accuracy molding

Accurate injection performance with high repeatability was realized by the in-house developed servo motor control technology to the V-LINE® method. It consists of a plasticization unit that only performs plasticization, and an injection unit that performs measurement and injection.
The improved accuracy of each position by controlling the measurement and injection position information by a closed loop, realizes high precision repeated stability of the plasticization, measurement and injection.

V-LINE® Injection Method

V-LINE®

Screw only performs plasticization
Constant heat history of resin during plasticization
Sequentially controls each process of plasticization and injection
Also controls behavior of the resin
No portion slides or shears the resin
No excessive shearing heat or over shearing applied to resin

V-LINE® Molding Process

  • Measurement
  • Backflow prevention
  • Suck back
  • Injection
  • Hold pressure

The V-LINE® realizes "3 stabilities,"

(1) melting condition of resin, (2) density of weighed resin, and (3) actual filling volume by independently controlling the entire process of the plasticization and injection.

Three stabilities
  • Easy to maintain a stable molding condition, which makes it easier to specify the cause of poor molding
  • Improves the process capability of the molding, which makes it easier to identify good conditions and poor conditions

Excellent Repeatability of Injection Process (Waveform)

The figure on the right shows a 30-shot overlapping waveform of the injection speed and injection pressure of the electric MS100. The waveform indicates high repeatability with less variation width.

MS100(P28S28)

Abundant plasticization and injection units standardly equipped with wear resistance and anti-corrosion performance

The MS Series allows for the selection of a screw diameter and plunger diameter suitable for the injection volume of molded products, and the plasticization and injection units in consideration of the speed and pressure, so that the machine can respond to a wide range of molded products.

Clamping Unit

Newly developed clamping unit in pursuit of high cycle, high accuracy and uniformity

A new clamping unit which reduces the mold opening/closing cycle was developed to promote electrification of the clamping operation by adopting the unique servo motor drive technology.
This also improves energy savings and noise reduction, as well as contributes to high cycling.
Also, the movable platen is supported by a linear guide to ensure a molding environment which suppresses variations.

Excellent Uniform Mold Clamping Force

The figure on the right shows the pressure sensitivity results, where pressure sensitive paper was inserted between the platens and test block to confirm the distribution of the mold clamping force when the mold is clamped in the MS100.
Excellent uniformity of the mold clamping force equivalent to a conventional machine could also be confirmed in the "MS Series Machine" which adopted the toggle method.

Merit

  • Strong contact in the center of the mold reduces the occurrence of burrs

High Accuracy Mold Open/Close Operation

The figure on the right shows the measurement results of the variation in parallelness, when the mold clamping - pressure release - mold opening is completed, where measurements were performed by a displacement detection sensor and measurement tool attached to the fixed platen and movable platen of the MS100.
Only a slight variation of the paralleness could be confirmed in the "MS Series Machine" which adopted the toggle method.

Merit

  • No stress is applied to mold components
  • No position change of movable platen

Utility

From manufacturing to maintenance. In pursuit of ease of use for all needs

The newly developed operation panel only for the "MS Series" is equipped with selector type switches.
Each unit operates by changing the switch in the direction to be moved, which provides a more intuitive and simple operation.
The adoption of the independently developed advanced control and communication system improved the high speed digital processing ability.

Realized Intuitive Operation

The newly developed operation panel only for the "MS Series" is equipped with selector type switchesEach unit operates by changing the switch in the direction to be moved, which provides a more intuitive and simple operation.
In order to avoid complicated operation of the switches on the operation panel, a new soft keyboard which displays the input values on a screen was developed.

Improved Productivity by Visualization of Molding Cycle

The adoption of a cycle time chart screen which enables the overall molding cycle to be checked at once, realized visualization of the cycle.
Accordingly, a molding operation that can be shortened can now be visualized at once, which reduces time loss. The cycle setting of each process operation can be customized easily, which contributes to time reduction of the molding cycle, and improves productivity.

Cycle chart screen

Substantial Support Functions

The operation method of the molding machine, error contents of the molding machine, and troubleshooting can now be checked in front of the molding machine with the newly added various sensors and maintenance screen, etc.
As a Help function, the operation manual can be displayed so that quick action can be taken when molding trouble occurs.
