Design and manufacturing of required screw torque
Positioning of lens on imaging LSI (CCD, CMOS sensor) of digital camera devises becomes tighter according to downsizing the devises. A few micro-meters or tighter positioning by mechanism of screw adjustment between a male screw of lens frame (inner) and a female (outer) screw of housing is required in recent cameras.
We have lot of experience of the design process and the mold-making to fabricate precision female screws with stable torque that realized by multi-cavity unscrew molding. Design and manufacturing the lens housings/holders with the female screw that fit to customer supplied male screws with optimum tolerance for suitable and uniformed screwing torque is available.
