    CM-30T-SERVO

    The SEALS CM-30T-SERVO adopts a high-precision, low-reaction-force servo nut runner that delivers detailed fastening data for every screw, ensuring speed, stability, and process transparency. When fastening parameters deviate from preset values, the system provides real-time alerts and generates a complete, traceable report to support quality control and auditing. This system supports multi-step fastening actions programmed into a single job—ideal for complex tasks that conventional electric screwdrivers cannot perform. Additionally, it allows precise control of rotation angle and speed to meet specific tightening requirements. The screw jaw is custom-built based on the screw type and working environment, ensuring reliable positioning and stable operation. The lever-activated design meets ergonomic and labor-saving standards; the screwdriver automatically initiates fastening with a single press of the lever. When paired with the TA-300 torque reaction arm, the tool maintains a stable vertical alignment, improves torque accuracy, and reduces operator fatigue. This setup is especially effective for high-torque shut-off applications where consistent torque control is essential.

  • 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.

    CM-40

    The SEALS CM-40 Automatic Screw Feeder is designed for speed, stability, and convenience. It integrates high-precision jaws, a reliable automatic feeding system, and Japanese-made torque-controlled pneumatic or electric screwdrivers to significantly enhance screw fastening speed and production efficiency. The screw jaws are custom-designed based on the customer's screw type and working environment, ensuring smooth and stable operation. SEALS also provides screwdriver model recommendations tailored to your specific screw and workpiece characteristics to ensure optimal fastening results. The material hopper adopts an up-and-down pushing board design to minimize screw surface scratches and keep feeding noise to a minimum. Combined with a fiber optic control system, the feeder intelligently stops when the chute is full, saving power and further reducing noise. The air blow feeding mechanism enables the next screw to be delivered to the jaw within 0.5 seconds—often before the operator moves to the next fastening point—greatly improving cycle time. A horizontal vibration chute is available to improve feeding performance for lightweight screws, painted screws, or screws with washers. The telescope-type screwdriver delivers consistent downward force directly into the sleeve of the screw, making it particularly suitable for self-tapping screws and wood screws. For automation integration, the screw feeder can be triggered via a dry contact to blow one screw per cycle. The screwdriver can also be mounted on a cylinder to enable vertical fastening strokes in fully automated assembly systems.

    CM-40T

    The SEALS CM-40T Automatic Screw Feeder is designed based on the principles of speed, stability, and convenience. It integrates pneumatic or electric torque-controlled screwdrivers, precision-engineered jaws, and a reliable horizontal feeding mechanism to significantly improve fastening speed and overall production efficiency. The system features an ergonomic lever-activated design that allows the operator to simply press the lever, prompting the screwdriver bit to automatically push downward and complete the fastening process. This design minimizes the required press stroke, reduces operator fatigue, and enhances productivity. The jaw is engineered to avoid direct pressure on the surface of the workpiece, effectively protecting product finishes and coatings from damage. To meet the demands of automated manufacturing, the CM-40T can also be integrated into various automation platforms such as XY tables, SCARA robots, 6-axis robotic arms, or other custom automatic assembly systems. The automation-ready version supports input/output signal communication and can seamlessly interface with major control systems.

    CM-20

    The CM-20 is a push-down type automatic screw fastening machine that integrates vibratory screw alignment, air-blow screw feeding, and an electric screwdriver system. It is designed for fixed workstations and repetitive fastening applications with stable cycle time. During operation, the front sleeve comes into contact with the workpiece surface. Once downward pressure is applied and the preset stroke position is reached, the screwdriver is activated to perform the fastening process, allowing operators to achieve accurate fastening through a simple and intuitive push-down motion. Fastening completion is determined by torque feedback from the screwdriver, and the system feeds the next screw only after proper tightening is confirmed. This control mechanism effectively prevents quality issues such as stripped threads, idle rotation, or misfeeding, making the CM-20 particularly suitable for mass-production assembly lines requiring consistent fastening quality and process stability.

    CM-20M

    The CM-20M is a handheld automatic screw fastening solution that integrates vibratory screw alignment, air-blow screw feeding, and trigger-activated fastening operation. This configuration allows operators to maintain a stable cycle time even when working at mobile stations or in multi-angle fastening applications. After alignment, screws are delivered to the fastening point via air-blow feeding and positioned by a magnetic driver bit, ensuring stable alignment and improved positioning accuracy during the initial fastening stage. During operation, the operator simply pulls the trigger, causing the driver bit to advance the screw and complete the fastening process. Since this fastening method does not require the front sleeve or fixture to press against the workpiece surface, it effectively reduces the risk of scratches or surface marks. This makes the CM-20M especially suitable for cosmetic parts, painted components, anodized surfaces, or products with surface protection requirements. It should be noted that the positioning mechanism of the CM-20M relies on the driver bit’s ability to hold the screw magnetically. Therefore, only screws with magnetic properties are applicable. For non-magnetic screw materials—such as most stainless-steel screws—a push-down type fastening model without magnetic dependency is recommended to ensure stable feeding and fastening performance.
