ima08This part is a central support unit for mounting all optical, electrical, and mechanical components for the imaging plate technology in use in dentistry. In medical technology, die cast zinc has been used for many years; however, overall, this area of ​​application is less known. The support unit has an is very sophisticated in design, mold making, and casting technique. Its intelligent component design achieves high dimensional stability even at high loads. The casting reveals a complex and accurate design tool in which the high design freedom of die cast zinc is fully utilized. The tool’s technical design allows high precision in all functional dimensions and delivers the required tolerances of the castings. The customer was very pleased with the switch to zinc alloy for this part. By using zinc alloy, subsequent processing or addition by means of screws or rivets could be avoided.
