Precision is everything in manufacturing, and that is doubly true for medical devices. Accurate testing and diagnostics depend on every fastener and joint being tightly connected, signals passing through at exactly the right wavelength without interference, and encountering exactly the right resistance. The need for exacting precision is why a Fortune 500 Healthcare Equipment Manufacturer has long depended on the accuracy of Mountz Torque tools, using a wide range of E-DRIV BF-Series electric screwdrivers in the medical device manufacturing process. When the company was ramping up production for a new ultrasound instrument, Roberto Vargas—sales manager at Mountz—helped them evaluate tools to create an optimal assembly environment for this very delicate and precise equipment.
Torque Needs in the Medical Device Manufacturing Process
Building the new ultrasound device required meeting different torque requirements and a variety of speeds, angles, and fastener and component stress/strain tolerances. To Vargas, it was clear that while the medical device manufacturer’s existing line-up of Mountz assembly drivers were outstanding tools for individual fastening, the manufacturer needed a flexible, all-in-one solution that could handle the different requirements. This would not only improve the efficiency of the medical device manufacturing process but also improve quality assurance at every step.
“The pressure to deliver quality is constantly increasing. Companies are looking for solutions that can better ensure the quality of their manufacturing processes. When it comes to torque, controllers offer a valuable benefit.”
– Roberto Vargas, Mountz Sales Manager
The solution? A single tool and controller with built-in functionality that can handle all the torque assembly needs. Vargas recommended an SDC controller that would enable them to use a single driver to control all their torque needs during the medical device manufacturing process. After a demonstration of how this programmable instrument could account for all the various torque factors that needed to be carefully controlled with a single driver, the company was understandably excited about the possibilities. Torque, speed, and angle could be managed with a single torque driver. A soft start and soft stop feature would also help to reduce the risk of cross-threading and over-tightening during assembly.
Consolidation Improves the Efficiency of Medical Device Assembly
The controller provides both precision and efficiency in a single device. The company decided to implement controllers across the production line for the new ultrasound device. While individually these controllers were more expensive than the company’s previous drivers, a single controller could do the work of multiple drivers, allowing for a reduction of overall costs and a significant reduction in both the time and money needed for maintenance and calibration of drivers. Implementing controllers also improved efficiency across the assembly line and in the medical device manufacturing process in general. The end result was greater efficiency of production and enhanced product quality.
The company would go on to upgrade to the MD-Series, a newer Mountz model which offers more options, an improved and more intuitive interface, and greater precision. The company still uses E-Drive electric screwdrivers in a number of other medical device manufacturing processes, but for their most delicate projects, the greater control offered by the MD-series controller is key. Simultaneously improving manufacturing speed and quality is a winning combination, and any assembly line can benefit from applying the following ideas:
- Consider the different torque applications your assembly line requires to determine if they are best fulfilled by a tool dedicated to each or by a controller that enables a single tool to fulfill them all.
- Assess whether or not there are multiple variables like torque, speed, and angle that require careful control.
- Review the number of interruptions to workflow and rejected assemblies to determine if cross threading is an issue and consider a tool with soft start/stop options to remedy it.
Precision torque control is vital in the medical device manufacturing process and in all assembly lines. Electric screwdrivers offer the precision that is needed to tighten fasteners in the most delicate of applications, and DC control tools combine precision and unsurpassed control over every aspect of the fastening process. It is a solution fit for even the most complex assemblies, offering more efficient production, oversight, and quality control.
