The dedicated injection unit of "No check-ring" system delivers stable shot-to-shot volume and weight
Silicone rubber is widely used in medical, automotive, aerospace, electrical,and industrial applications, because of its unique characteristics in flexibility over wide rage of temperature, high resistance to compression set, a wide range of viscosity, and higher resistance to chemicals. Recently, there are increasing needs for LSR molding. As a result, the needs require better performance in injection molding machines to meet more complex shape and higher accuracy LSR parts.
Sodick Plustech offers a dedicated design for LSR machines with the V-LINE Plunger system,"SIL-PRO" series. Through the experience with ultra-precision thermoplastic injection molding machines, SIL-PRO series provide outstanding performance on your LSR molding needs
Sodick Plustech LSR Injection Molding MachineV-LINE "Plunger" Injection System
Dedicated & Optimum Design for Liquid Injection Molding --(e.g.) 2.00 cP super low viscosity material to Gumstock material handling capability
No Short Shots, No Over-packing - Flashless Molding -- (e.g.) 5,000 shot for cold deck 2-cavity o-ring shows zero (0) minimum cushion deviation
An exceptional injection accel & decel resolution -- (e.g.) Velocity profile in a increment of 0.1mm/sec (0.004"/sec)
Minimizing weight and size deviation -- (e.g.) Least weight deviation for 50 intentional short shot showing stdev. of 0.0019
|V-LINE PLUNGER SYSTEM||CONVENTIONAL SCREW SYSTEM|
|While metering by small diameter transfer screw, screw position is stationary, so that it will provide very stable material density.||Screw is reciprocating while metering. Material feeding pressure from pump apply from screw to nozzle.|
|The V-Line Plunger System is equipped with a patented backflow prevention, which is mechanically engineered to shut off the material feeding pressure before injection (EXACT DOSING system). The V-Line Plunger system is built to provide an exceptional low speed low pressure injection control.||In the conventional reciprocating screw system, it is extremely difficult to control low viscosity material shot size. The "Check Ring" is at open position when metering is finished. The material leakage at injection is evident due to the feeding pressure from screw side. (Pressure has to be compensated to close the check ring).|
Thermoplastic machines provide ultra-precision repeatability, superior advanced polymer process performance, and push-to-the-limit thin wall molding processing.
Micro molding machines offer a true micro molding approach to meet today's most demanding "Miniaturization" applications. The Two-Stage Plunger injection system delivers exact dosages.
A wide range of vertical clamping machines supports today's challenging insert molding needs. Sodick Plustech is a leader of precision vertical injection molding machine manufacturer
