Designed for the Most Difficult
During NPE2018, we will be introducing the OPM250, Metal 3D Printer along with four new injection molding machines models: the MS100 New Electric Horizontal Molding Machine, the LP20VRE Micro Vertical Molding Machine, the GL60A Horizontal Molding Machine, and the GL30A-LP Micro Horizontal Molding Machine. Sodick will demonstrate their ultra-precision molding capabilities, advanced molding controls and monitoring systems, along with their new IoT solutions. Click here for our location.
OPM250L – Metal 3D Printer with High Speed Machining
Metal 3D Printer, OPM250
The OPM250, Metal 3D Printer, is a single process machine which combines laser metal sintering and high speed milling within the same workspace, allowing users to create finished 3D printed molds within a single machine. Sodick’s additive technology improves mold cooling channels and cycle times and streamlines mold design, significantly reducing the number of components necessary to create a complete mold, resulting in operational savings.
MS100 – a new 100-ton Electric Injection Molding Machine
MS100 New Electric Horizontal Molding Machine
The MS100 is a new 100-ton Electric Injection Molding Machine. The machines new toggle design clamping mechanism contributes to faster cycle time and energy savings. This model is Sodick’s first Electric Molding Machine. During the show, the MS100 will demonstrating a conformal cooling mold made by OPM250, and automated by Star Automation. The molded part is a printer ink cartridge housing, the demo will enable visitors to learn about the benefits of 3D cooling channels that reach closer to the surface of the mold – providing more even cooling, reducing deformation, and shortening cycle times.
Back Flow Prevention
V-LINE ® Two-Stage Injection System eliminates the check ring. Prior to injection, the plasticizing screw is indexed forward creating a positive shut-off (EXACT DOSING). This action prevents any opportunity for back flow of molten material back into the melt.
V-Line Positive Shut-off
Each pellet goes through the same thermal exposure by stationary screw rotation. Processing material is not affected by injection.
Conventional System
Check ring’s close timing occurs at injection (inconsistent). Screw tips are a source of frictional heat, material hang-ups, intermittent malfunctioning.

Injection
The V-LINE injection is controlled by a closed loop system which monitors actual speed vs. set speed and maximum melt pressure. A linear encoder detects plunger position and a pressure sensor monitors injection pressure. User selectable limits can be easily input on the process monitor screen. Once the exact amount of material is transferred into the injection chamber, the injection plunger is retracted via the melt pressure and is returned to a set position. This design eliminates the need for a check valve, which is a primary source of material degradation and shot volume inconsistency. The exceptional speed of the controller provides real time response during injection and records the melt cushion in 0.001″ for accurate process stabilization.
V-Line Decompression
V-LINE® decompression function is very effective since the dosed material is encapsulated in the plunger chamber like a hypodermic syringe.
V-Line Plunger Injection
V-LINE® Plunger Injection is very reliable due to high response, low mass and low inertia mechanism.
Conventional System
Check ring’s close timing occurs at injection (inconsistent). Screw tips are a source of frictional heat, material hang-ups, intermittent malfunctioning.
Conventional System
There is always speed and pressure loss at injection because of leaked material. While leaking, the metered material is exposed to high shear heat which generates degradation and gas.
