  • CM-300→Three-Axis Automatic Pin Insertion Machine – Woodworking Application - model:CM-300
Three-axis Automatic Peg Pin Insertion Machine
    CM-300→Three-Axis Automatic Pin Insertion Machine – Woodworking Application

    In this application, the processed material consists of long wooden workpieces commonly found in the woodworking industry. To enhance production efficiency and machining precision, the customer implemented SEALS customized automation equipment for system upgrading.


  • CM-30→Refrigerator & Appliance Assembly Application - model:CM-30
Automatic Screw Feeder with telescope screwdriver set
    CM-30→Refrigerator & Appliance Assembly Application

    In refrigerator assembly lines, fastening screws vertically on side panels is often labor-intensive and error-prone. The CM-30 Automatic Screwdriver, with its 90-degree press-down design and auto-feeding system, allows operators to complete fastening quickly and accurately with a simple downward press — boosting efficiency and reducing physical strain.


  • TRPC-A3→Low-error assembly processes - model:TRPC-650A3
    TRPC-A3→Low-error assembly processes

    The TRPC series combines two major components: ➤A3 Torque Arm (350A3 / 650A3 / 900A3) – Available in three lengths to suit different workspace and workpiece sizes ➤CL-A3 Digital Management System – Offers touch-screen guidance, task control, and real-time torque monitoringTogether, they form the TRPC-350A3 / 650A3 / 900A3 models, differentiated by torque arm length and coverage area.


  • CM-200→Eyeglass Hinge Screw Fastening - model:CM-200
Automatic Screw Feeder for Eyeglass Frames
    CM-200→Eyeglass Hinge Screw Fastening

    The CM-200 is specially designed for the screw fastening process at the hinge joints of eyeglass frames. Traditionally, this process required manual operation due to the small screw size and irregular frame structure, often leading to issues such as misaligned screws, over-tightening, or frame scratches, which affected quality consistency. By integrating a dual-axis screwdriving mechanism with an automatic index table and gripper system, the CM-200 enables precise positioning and simultaneous fastening of dual screws. This significantly reduces cycle time per unit while minimizing operator skill dependency—making it ideal for high-volume eyeglass frame production lines.This system has been successfully implemented by OEM factories and private label eyeglass brands, helping them optimize manpower allocation, increase production efficiency, and achieve consistent product quality with a high yield and low defect rate.


  • CM-500→Gas Meter Top & Bottom Cover - model:CM-500
Automatic Screw Feeder for Gas Meter Top & Bottom Cover
    CM-500→Gas Meter Top & Bottom Cover

    Designed to address the precise and repetitive demands of gas meter cover assembly, the CM-500 offers an efficient and reliable automatic fastening solution.Equipped with five servo-controlled screwdrivers, the machine fastens five screws simultaneously, making it ideal for securing gas meter top covers to their bases. The integrated automatic screw feeder eliminates the need for manual screw placement, saving time and ensuring consistent quality across each unit.Customizable jigs allow for quick adaptation to different gas meter sizes, while a built-in light curtain sensor enhances operator safety. Whether you’re handling small batch runs or large-scale production, the CM-500 is built to deliver consistent, professional results.


  • SB / HSB Series → Line Organization and Labor-Saving Applications - model:SB / HSB Series
Tool Suspension for Assembly Line Applications
    SB / HSB Series → Line Organization and Labor-Saving Applications

    In conventional production lines, tools are often placed on workbenches or floors, occupying valuable workspace and creating clutter. Operators must repeatedly bend or lift to access tools, leading to muscle fatigue and even occupational injuries. Additionally, accidental tool drops not only increase the risk of damage but also compromise operational safety.With the SEALS SB / HSB Spring Balancer Series, tools can be suspended at the optimal height in a “weightless state,” allowing effortless and smooth operation. The built-in safety wire prevents tool drops, keeping the workspace neat and organized while enhancing safety. Covering a full load range of 0.3–120 kg, the series accommodates a wide variety of tools—from electric screwdrivers, glue guns, and drills to spot welders and heavy polishing machines—making it especially suitable for assembly lines and heavy-duty applications.


  • TAB / THB Series → Hose Management & Air Supply Integration - model:TAB / THB Series
Hose Management Application
    TAB / THB Series → Hose Management & Air Supply Integration

    《Case Description》 The TAB / THB Series Hose Balancers are mainly applied in production lines for the suspension and air supply management of pneumatic tools. The TAB Series (hose inner diameter 6.5 mm) is suitable for small pneumatic tools such as screwdrivers, cutters, and light pneumatic fixtures. The THB Series (hose inner diameter 8 mm) is designed for high air consumption tools such as impact wrenches, grinders, and riveters.Traditional pneumatic tools often suffer from messy hoses on the ground, which affect both efficiency and safety. By using hose balancers, hoses are suspended overhead, preventing tripping hazards, accidental pulling, or unstable air supply. The smooth retraction and adjustable tension allow operators to freely control their pneumatic tools, achieving an organized production line and higher efficiency.


  • CM-A1 ~ A4 → Automatic Nipple Feeder – Bicycle Rim Assembly Line - Model: CM-A1 ~ A4 Series
Application: Bicycle Rim Assembly
    CM-A1 ~ A4 → Automatic Nipple Feeder – Bicycle Rim Assembly Line

    《Case Description》 In bicycle rim assembly lines, traditional manual methods require workers to repeatedly pick up G12–G15 nipples and fasten them one by one. This process is not only time-consuming but also prone to issues such as dropped parts, mismatched sizes, and inconsistent quality. These challenges become more pronounced in high-volume production, often creating efficiency bottlenecks and increasing rework rates.The SEALS CM-A1 ~ A4 Automatic Nipple Feeder for bicycle rims automatically delivers nipples precisely to the screwdriver tip. Operators only need to align the hole and push lightly to complete fastening. This design effectively shortens cycle times, enhances overall line stability, and reduces quality variations caused by operator skill differences. Actual application results show that production efficiency improves by more than 30%, training time for new staff is cut in half, and defect rates are significantly reduced. This helps production lines respond quickly to market demand while achieving the dual goals of high efficiency and high quality.
