Cap size: ø90.7 X 93 X 25mm Cap weight: 36gm Material: HDPE Mold: 4 cavities The thread part of this cap is designed with thread rotation off, and the motor device is used to drive the gear to rotate. The cap must be designed with a stop device to prevent the product from following the rotation when the thread rotates, resulting in the scratch of the cap thread. After the thread part of the cap is separated, use the ejector plate to eject. Compared with thread strength and thread rotation, thread rotation is more difficult to make, which requires high-precision processing equipment, high installation accuracy and accurate positioning between plates, otherwise it is easy to cause the problem of parts stuck and motor or oil cylinder not moving.
