[0002] The hand mold base is a component of equipment commonly used in the manufacture of disposable gloves. It is usually made of metal such as manganese steel or carbon steel, with a certain weight and good appearance. The design and manufacture of the hand mold base needs to consider its use environment and functional requirements. Therefore, different hand mold bases may have different designs and characteristics. The rocker arm is a mechanical component consisting of an arm and a rotating shaft, which is used to transmit power or control the direction of movement, converting rotary motion into linear motion, or converting linear motion into rotary motion.
