Built for high production environments, the Mountz air screwdriver tools provide durability, power and speed for assembly and manufacturing applications at an affordable price. Designed for safe operation and increase comfort for operators, the air screwdrivers provide lower noise decibels than comparative pneumatic screwdrivers as well as minimal vibration and low torque reaction on the operator.
The Mountz rugged pneumatic screwdriver increases productivity and enhances product quality through precision torque control and user comfort. Featuring a patented clutch design, the assembly air tools deliver reliable accuracy with repeatable torque control. The clutch mechanism shuts off the air supply when the preset torque setting is achieved, preventing over-torque conditions from occurring.
A heater manufacturing company was experiencing improper torque control, which was costing them money in rework time and product being damaged by the assembly tools that they were using on the production floor. The heater manufacturer assembles floorboard heaters and in-wall bathroom heaters for residential construction. A deformation with the coated sheet metal used to house the heating element in the floorboard unit occurred during the fastening process.
The production manager started a root cause analysis program to eliminate this costly production problem. They started to test the process and determine what was causing the issue. Using a torque analyzer system they did some destructive testing. They wanted to first determine “at what torque value” that was applied during the fastening process would cause the deformation in the product’s coated sheet metal.
Once the proper torque value was determined for the product, they next examined the pneumatic tools being used in the assembly process. The pneumatic torque screwdrivers were set once every six months or at the time of purchase at a preset torque value. This torque value, however, was derived from a chart supplied by the fastener manufacturer, which was at 80% of the fastener yield value. The torque value did not account for the material the fastener was clamping together, which was causing product deformation, paint chipping, increased rework, and decreased their productivity.
Regular torque tool calibration and re-calibration guarantees the operator repeatable accuracy and adherence to international standards. Calibration also ensures torque equipment is operating to peak performance and can highlight potential tooling problems before they arise perhaps due to tool wear or broken components. Torque calibration equipment can be found in many industry sectors such as:
Research & Development
As technology moves ever forward, with the implementation of new materials, processes and assembly techniques there is a demand for accurate torque application. The accurate calibration of torque tools is a vital part of this process.
Inspection & Quality Control
The accurate and repeatable application of torque is fundamental in any quality control process in order to save time and money. Torque equipment calibrated regularly and accurately can and will allow you to reach these goals:
Torque tools calibrated correctly can provide repeatable accuracy saving time, money, materials and labor. Regularly calibrated and certified torque tools, reduce the risk of products failing in service, saving money from warranty and re-work costs.
Engineers involved in servicing may have to apply various and accurate torque settings to a range of components. Accurate calibration of these tools is vital in achieving accurate torque applications.
Mountz unveiled its new trade show booth at the Assembly Technology Expo at the end of September in Chicago. Mountz showcased several new products during the event including FlexPower pulse tools,PosiControl Torque Arms and brushless electric screwdrivers. Engineers that visited the Mountz booth were able to get a preview of our new battery torque screwdrivers with torque up to 30 N.m., which will be released in November.
