Automatic Screw Feeder with telescope screwdriver set

CM-30

SEALS Automatic Screw Feeder, CM-30, could keep the low noise and less scratch of screw surface in material hopper due to its up-and-down pushing board design. With Fiber Optic control, it also reduce noisy and saving power while it is full in chute. By the air blow feeding system, you can get the next screw within 0.5 second in jaw before you move to the next fasten position. No need to pick screw, no need to put screw into drive bit and prevent rust due to hand sweating. Meanwhile, the telescope type screwdriver set deliver the downward force into the sleeve of screw. It is quite essential for self tapping screw and wood screw. For automation integration, the screw feeder can be control to air blowing one screw by giving a dry contact. And, the screwdriver also can be installed into a cylinder for fastening stroke action in fully automation assembly line.
Automatic Screw Feeder with servo nut runner

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.
Automatic Screw Feeder with Lever-Activating Design

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.
Vibration Bowl Type Automatic Screw Feeder for Two Screwdriver Sets

CM-502

The SEALS CM-502 Vibration Bowl Type Automatic Screw Feeder is designed for speed, stability, and convenience. It combines a high-performance vibration bowl feeder, precision-engineered screw jaws, and pneumatic or electric torque screwdrivers to significantly enhance production efficiency. A single screw feeder unit is capable of supplying screws independently to two separate screwdriver sets. Each channel operates with its own control system, allowing two operators to work simultaneously at different speeds. This flexible design supports up to 45 screws per minute per channel, effectively reducing labor time and unit cost. The vibration bowl is compatible with screw sizes ranging from M1.0 to M8 and screw lengths up to 30 mm, making it suitable for a wide variety of fastening applications. Compared to sword-type feeders, the vibration bowl offers a larger screw capacity and more stable feeding. With a simplified mechanical structure, the CM-502 is easy to maintain, reducing downtime and ensuring long-term operational stability.
VGA, DVI Card Automatic Screw Feeder

CM-B1

The SEALS CM-B1 Automatic Screw Feeder is specially designed for fastening hexagonal standoff screws onto VGA, DVI, and other computer interface cards. Built for speed, stability, and convenience, the system integrates precision-engineered jaws, a high-efficiency feeding unit, and pneumatic/electric torque-controlled screwdrivers to ensure fast, accurate, and consistent fastening. Equipped with an auto bit-pushing function, the CM-B1 supports horizontal screw fastening, making it ideal for inline applications on conveyor belt assembly lines. This feature allows screw fastening to be done directly in-line rather than offline, significantly reducing handling time and increasing throughput. To accommodate the narrow spaces near connectors, the screw jaws are designed extra-thin to avoid interference with VGA, DVI, or similar connector structures, while still securely aligning with the screw holes for precise fastening.
Programmable VGA, DVI Card Automatic Screw Feeder Machine

CM-40AUT

The SEALS CM-40AUT is a professional, programmable automatic screw feeder specifically engineered for assembling VGA, DVI, and other interface cards. Designed to handle two or four standoff screws per board, it offers a teachable positioning system, allowing operators to store up to 200 sets of fastening positions—ideal for high-mix, low-volume production environments. To accommodate narrow screw locations near VGA and DVI connectors, CM-40AUT adopts extra-thin jaws that ensure accurate alignment without interference. Similar to other SEALS models such as CM-30T, CM-40T, and CM-B1, the CM-40AUT features an ergonomic auto bit-pushing mechanism, which enables smooth horizontal fastening without requiring operators to manually press or hold the PCB—making it especially suitable for use on conveyor belt systems. For integration into fully automated production lines, both CM-40AUT and CM-B1 models can be incorporated with XY tables, SCARA robots, 6-axis robots, or other customized auto assembly equipment. The automation versions also support I/O signal communication, allowing seamless control and feedback with central control systems.
