  • Magnetic Type Automatic Screw Feeding Machine
    Magnetic Type Automatic Screw Feeding Machine
    CM-30M

    The SEALS CM-30M Magnetic-Type Automatic Screw Feeder is designed to provide high efficiency and precision in handheld screw fastening applications. Utilizing a push-pull jaw mechanism and a magnetically driven bit, the screw is instantly ejected and securely held at the tip, fully exposed for quick and accurate alignment with the screw hole. This design is especially ideal for challenging environments where traditional jaws cannot reach—such as deep holes, wiring areas, curved surfaces, or tight spaces near walls—enabling precise fastening even under constrained conditions. The electric screwdriver set features a lever-activated, brushless torque control design, offering high precision, easy torque adjustment, and long-term durability. Without carbon brushes, the driver remains cool during extended use and provides a more comfortable experience for the operator. The screw feeding unit is built to be rugged and durable, with a simple and compact structure that allows for quick installation and easy adjustment. Most importantly, setup can be completed by a single operator with minimal effort.


  • Torque Linear Arm ( 182-561mm working radius)
    Torque Linear Arm ( 182-561mm working radius)
    TA-300S

    Seals Torque Reaction Arm is designed to avoid repetitive work and excessive use of arm injuries in daily work. We provide Torque Reaction Arm to improve the ergonomic manufacturing process to eliminate instant torque and weight loads After clamping the screwdriver, the Torque Reaction Arm can be operated back and forth, left and right, up and down, and can rotate freely at 360°. It can always support the screwdriver. The maximum working diameter is 1122mm. Various screw locking operations can be carried out within the range to reduce work The failure rate ensures that the screwdriver locks the screws at a vertical angle, improves the quality of screw locking, and reduces product quality problems such as operator errors and defective locking screws. This Torque Reaction Arm can effectively reduce the space requirement of the workplace. With the help of the spring lifting force of the Spring Balancer, the suspended arm frame is in a weightless state, which reduces the labor status of personnel, improves labor production efficiency, and creates a safe and efficient working environment. It can be directly fixed on the work surface (recommended) and a C-shaped table clamp is provided, two installation methods.
