V-LINE Two-Stage Plunger System
Sodick Plustech eliminated the check ring and all of its associated flaws to bring the ultra-precision injection molding machines
Most important roles of Injection Molding Machines are:
Constant plasticizing heat profile, Constant material viscosity Constant filling volume in Constant time Constant holding pressure in Constant timeDesigned on three principles, the Sodick Plustech achieves perfect harmony of critical plasticizing, and injection functions. These principles are the cornerstone of the V-LINE Two-Stage Plunger design. By satisfying these principles the Sodick Plustech machines became a value added solution.
Plasticizing
The Sodick Plustech utilizes a two-stage "V-LINE" method for plasticizing and injection. These proven concepts allow for consistent shot volumes and melt densities unmatched with standard designs. Unlike conventional in-line reciprocating screw system, the V-LINE plasticizing screw remains stationary during material transfer minimizing axial wear and ensuring each pellet sees the same heat profile.
Back Flow Prevention
Sodick Plustech 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 backflow of molten material back into the melt stream.
Injection
The "V-LINE" injection is controlled by a closed loop system comparing actual speed to set speed and maximum melt 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 that is retracted via the melt is maintained to a set position. This design eliminates the need for a check valve, a primary source of material degradation and shot volume inconsistency.
Hybrid Direct Clamping System
Sodick Plustech provides Ultra-Precision Hybrid Clamping System, using both electric servomotor and hydraulic clamping cylinder as drives. This proven hybrid system uses a central servomotor and ball screw for mold opening and closing. After clamping locks engage the central ram, a central hydraulic "pancake" cylinder generates direct clamping pressure.
Control System
Sodick Plustech machines are incorporates with proprietary Machine Control Derived from CNC, EDM Machine Tool Experience technology. Sodick Plustech offers the highest level of precision position, speed and pressure control necessary for ultra-precise, repeatable molding.
