Further realized high cycle molding based on high accuracy and stability
V-LINE® injection molding machine which has received high evaluation in the fields of precision and complicated plastic molding. This series consists of superior features, such as high accuracy and stability.
The "MS Series" is Sodick's latest injection molding machine based on this excellent performance which has adopted the "eV-LINE" system integrated with the independently developed servo motor control technology in the
drive portion of the plasticization & injection units.
The drive portion of the newly developed mold clamping unit realizes further improvement of high cycle molding and productivity, and energy saving effect. Since advanced high precision and complicated plastic molded products are reguired, a wide range of application ability has been demanded for injection molding machines.
One solution is the "eV-LINE Electric Injection Molding Machine MS Series."

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
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
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.
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.
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.

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.
Molding cycle Compared to conventional machineReduced by 20%
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.
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.
No stress is applied to mold components
No position change of movable platen
MS100 mold axis deviation (Mold deformation)
In pursuit of high cycle performance and eco-performance The "eV-LINE" system integrated with the independently developed servo motor control technology has been adopted for the drive portion of the plasticization and injection units, and the drive portion of the newly developed mold-clamping unit, which realizes high cycle molding and energy savings.
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.

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.
