SD40E Clamp Features
Running round-the-clock at high speeds, the long-term reliability of the
SD40E is ensured by Sumitomo's field proven double-toggle clamp design.
For clamping, the SD40E features a Sumitomo-built, direct-drive, digitally
controlled AC servo motor. Full closed-loop control of mold open/close
position and speed, plus monitoring by precise optical encoders, ensure
maximum mold protection and consistent molding cycles.
Three-stage mold open/close speed control can be used to tailor machine
operation to specific mold requirements. Excellent clamp force linearity,
from low to high tonnage, enables optimum setting of clamp force. And
selectable auto-ramping modes can be used to optimize clamp open and
close profiles for fast cycling with shock-free movement.
Other specialized disc molding features of the SD40E include a
temperature-controlled platen and a gate cut mechanism in the moving
platen. These features, combined with the precision injection features,
help ensure uniform replication over the entire data area, extremely low
birefringence, and excellent dimensional characteristics with low tilt angles.
