LIQUID SILICONE & RUBBER (Sil-Pro
series)
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.

V-LINE Plunger System
| V-LINE Plunger System |
 |
| The V-Line system is equipped with our patented back-flow prevention, which is
mechanically engineered to shut off the material feeding pressure before
injection. Our V-LINE Plunger system is built to provide an exceptional
low-speed/low pressure control (0.004"/sec injection speed) using our linear
motor technology.
|
| Conventional IN-LINE Screw System |
 |
 |
| 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). The "shut-off nozzle" is required because there is constant
feeding pressure from screw to nozzle.

LINEAR MOTOR TECHNOLOGY
Sodick Plustech develops the injection valve using Linear Motor technology as a
drive. By using a linear motor to control the spool of injection valve, the
step response becomes 10 times faster than that of conventional servo valve
(3msec). As a result, V-LINE Plunger achieves excellent injection control
including acceleration and deceleration of the injection speed, vp switch-over
position stability, and linearity of molding profile.
