In response to the demand from the assembly industry for a less costly, but highly repeatable and efficient cell based torque driver, Mountz introduces the Hybrid, a revolutionary change in repeatable screw fastening technology. The patented HD Series Torque Control System is the world’s first torque control tool using both air and electric power to set and control torque. The HD’s precise pneumatic pressure sensor and patented algorithm allow for precision digital torque selection. Adjustable torque and parameter settings occur with “one touch” on the front panel or through PLC signal. A high accuracy, brushless DC motor provides repeatable torque control. The entire system sells for 70% less than conventional technology.

Companies are looking to save time by improving the efficiency of their production space and methods. They want these results in a versatile production environment equipped for fast changeover to different projects. The HD Series is technically innovative, but most important it hits a bulls eye on the key objectives customers seek in advanced fastening solutions – lower cost, ability to leverage investment over multiple products, technology that is easy to learn and use and tangible quality benefits. Lean manufacturing techniques helped to drive the Hybrid product development, which was designed in cooperation with a major electronics product maker who clearly specified their desire in a product. We simply listened and collaborated.

Complex fastening regimes with multiple screws and high-speed production can lead to miss screws and compromised quality. Get it right the first time around with batch count and line control functionality.

Problem: On fast moving assembly lines, operators can miss screws.
Solution: Screw counting capability with operator feedback signal.

Problem: Operator needs to mark every screw in order to check each one is fastened.
Solution: Screw counting function and line control capability. When all the screws are in place, the torque screwdriver sends a signal to the line and next batch arrives.

Screw Counter
A screw counter helps manufacturers detect and eliminate costly screw-fastening errors during the assembly process. Using a screw counter is like putting the eyes and ears of a quality control manager where they are needed most – right on the assembly area. Screw counters verify that all fasteners have been installed and were seated to the tools preset torque setting. These units take the control of the assembly process out of the operator’s hands.

Designed to detect cross-threading, omissions, unfinished rundowns and cycles incomplete, a screw counter ensures the assembly process is done correctly the first time. The device typically operates jointly with assembly tool like an electric or pneumatic screwdriver or some torque control systems have it built-in. The screw counter features the ability to ‘learn’ the characteristics of not only the assembly tool but also that of the application that it is being used on. This allows the screw counter to distinguish between a fastener that was properly seated and one that was either stripped or cross-threaded.
