One, the size of the pleated shield when unfolded is equal to twice the height of the pleat. Two, the distance between the guide surface of the mechanical equipment and the accordion shield is at least 6 mm and 15 mm. Three, standard pleat heights: 20mm, 25mm, 30mm, 40mm, 45mm, 50mm, 55mm. Four, the compressed pleat thickness is 6mm. Additionally, the surface of the accordion shield is smooth and aesthetically pleasing, adding infinite color to the overall design of the machine tool. It not only provides practical protection for your machine tool but also enhances its visual appeal, thereby increasing the overall value of the machine tool. Its sliding properties on the track can be improved by using special sliders. If there is a significant acceleration acting on the shield, a synchronizing device can be used to ensure a uniform stretching of the shield.
