Problem When using an electric screwdriver to tighten bolts, the actual torque can overshoot the preset value—known as torque overshoot or over-torque. This risks stretching or breaking the bolt, degrading joint quality and increasing scrap and rework. Root-Cause Analysis All AC electric nutrunners on the market can exhibit torque overshoot; the phenomenon is not brand-...
An automatic screwdriver machine is an automation device that uses motors, position sensors, and other components to feed screws, align them with the hole, and drive them to the specified torque. It then verifies the tightening result with the help of torque testers and position sensors. According to coordinate configuration, these machines are classified into Cartesian,...

In modern automotive manufacturing—especially when assembling complex, space-critical parts such as car seats—the choice of tightening tool is decisive. Conventional inline electric screwdrivers are often too long or limited in their operating angle, making it impossible to reach recessed fasteners. This not only slows the line but also risks inconsistent joint quality. ...
In automated production lines, feeding fragile parts has long been a headache for manufacturers. Traditional vibratory bowls rely on fixed tracks to orient components, which introduces several drawbacks. When parts are forcibly guided along these rigid tracks, unavoidable friction occurs. For fragile components, this friction can range from minor surface scratches—compro...
Traditional vibratory bowls have been used for decades and feature a simple principle: continuous high-frequency vibration drives parts along circular steel rails, with optional sensors or reject stations added at the track. Because the rails must be custom-machined for every part geometry, they are neither universal nor reusable. They are therefore best suited to long-r...
In today’s production lines, finished plastic parts must be delivered to downstream equipment in a precise, repeatable order. Traditional methods—manual loading or conventional vibratory bowls—fall short: Manual placement is slow and labor-intensive. Standard vibratory bowls cause part pile-ups, inconsistent counts, and no orientation/quality screening. Special geomet...
