KRD41 Small Drop Test Machine

Name: KRD41 Small Drop Test Machine
Brand: CME Technology Co., Ltd.

KRD41 series small drop tester is a swing arm type servo lifting drop test machine, which is suitable for free-fall (face, edge, and angle) tests of small consumer electronics and components. It is equipped with a height display and a sensor for height tracking, which can accurately give the product drop height. It can simulate falls in which a specimen, normally in the unpacked state, or simulate repeated falls dropped with packaging to evaluate the impact resistance or the damage caused by the fall of the product during transportation. As one of the drop test equipment suppliers, our KRD41 drop test machine complies with the international standards ISO2248, IEC68-2-27, JISC 0044, IEC 60068-2-32 and ISTA relevant standards.

TABLE OF KRD41 SMALL DROP TEST MACHINE

KRD41 drop test machine is mainly composed of an impact plate, servo motor lifting mechanism, turning worktable, guide pillar, fixture, table extension mechanism, release and unlocking mechanism, damping device, etc. The structure picture is shown in the figure below.

The working principle of the vertical drop test system can be briefly described as the lifting cylinder lifting the working table and the specimen to a certain height, and is released by the electromagnetic release mechanism. Since the work surface adopts a compressed energy storage spring during the lifting process, the work surface falls at a speed greater than the falling speed of the specimen. The specimen keeps its original state (surface, edge, and angle) and falls freely, bumps with the bottom plate, and completes the test requirements.
