4-axis parallel injection compression control
High precision light-guiding plate thickness control
The 4-axis parallel injection compression control enables to homogenize the thickness of and reduce distortions like warping on molded thin light-guiding plates, by detecting the mold opening amount directly with the mold position sensors installed at four corners of mold and controlling four tie bars with the feedback control, coupled with our original feedforward compensation, of high-response hydraulic servo valves.

Deviation of thickness on prototype PMMA light-guiding plate (equivalent to 40")
Resin, mold and molding conditions e.g. can change the Deviation of thickness.
