Pulse tools increase productivity and enhance product quality through precision torque control and user comfort. Regular tool calibration ensures repeatable accuracy and adherence to international standards. A pulse tool is a power tool that must be properly calibrated and maintained. Torque testing ensures the pulse tool is operating at peak performance and can highlight any potential tooling problems before they arise perhaps due to tool wear or broken components.
Torque tools go out of calibration with use. To maintain consistent accuracy, torque tools must be checked periodically for wear or defective parts. A power or hand torque tool is a measuring tool that must be properly calibrated and maintained. Regular torque tool calibration and re-calibration guarantees the operator repeatable accuracy and adherence to international standards. Torque testing 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.
How do you measure torque? Mountz, “the Torque Tool Specialists,” has over 45 years of experience providing torque tool solutions to industries like medical, aerospace, electronics, energy, automotive and others. We are an ISO 9001 certified company and ISO 17025 accredited company.
Controlling torque is essential for companies to ensure their product’s quality, safety and reliability isn’t compromised. The failure of a three-cent fastener that isn’t properly tightened can lead to catastrophic or latent failures. Fasteners that are insufficiently torqued can vibrate loose and excessive torque can strip threaded fasteners. Torque measurement should occur in three facets of the assembly process.

Torque measurement tools, like torque analyzers and torque sensors are used prior to the assembly process. The equipment is used for tool setup or conducting tool capability studies. For tool setup, the tool crib or lab will want to set the torque tool according the torque specification required for the application. For tool capability studies, technicians need to ensure that the torque tool can provide the necessary torque and repeatability that’s required for a potential application.

Experience, Quality and Reliable
In the manufacturing and assembly world, tightening, controlling, or measuring torque fasteners is imperative for production efficiency. An inadequately torqued fastener can vibrate or work loose: conversely, if the tension is too high, the fastener can snap or strip its threads. Faced with these problems, manufacturers are realizing that precise torque control can spell the difference between a safe, reliable, and economical product and complete disaster.
Anybody who has to tighten a threaded fastener and needs to control, monitor, or measure torque needs sophisticated torque tools. If manufacturers want to save money, make their workplace safer, enhance product quality, or reduce their exposure to liability; only specialized high-quality torque tools will get the job done properly.
1. Pick the Right Torque Tool
A wide variety of torque tools are available to control or measure the torque applied to fasteners, from electric screwdrivers to large industrial torque wrenches, torque analyzers, torque sensors, pneumatic screwdrivers and torque multipliers. These tools utilize calibrated torque setting mechanisms that may be factory pre-set or user-definable. When the specified setting is reached, the tool gives a visual, audible, or tactile signal. The anticipated production output, the type of materials being joined, the amount of torque required, and the specified fasteners determine the selection of tools for a given application. Lighter materials such as wood or plastic may require only lightweight tools; likewise, heavy materials such as steel may require stronger or larger tools. If torque data must be gathered during the assembly process or quality process, tools should also have connection ports such as USB, RS-232 and other cabling connections.
2. Establish a Torque Calibration Program
Calibration is fine-tuning the torque control process in a production environment. Torque calibration should be checked periodically to determine whether torque tools are operating at their proper settings. Many tools don’t have a locking device, and users may easily change their torque settings. When this happens, the tool falls out of adjustment.
A regularly scheduled calibration program enables quality control personnel to correct divergence from proper settings, whether it’s because of normal slippage over time or because of adjustments to the tool. Begin by setting a calibration interval initially based on severity of the application and the tool manufacturer’s recommendations. If the applied torque values are out of range, cut the calibration interval in half and re-test the tools. Read the rest of this page »

In the manufacturing industry, one way to report and evaluate the process capability and process performance is through the statistical measurements, like Cpk.
Definition: Cpk = Cpk = Process Capability Index. Adjustment of Cp for the effect of non-centered distribution. Cpk measures how close you are to your target and how consistent you are to around your average performance.
Cpk measures two things: 1) how close the mean of the readings are to the center of the lower and upper spec limits (ideally, the mean of the readings must equal the center of the spec limits); and 2) how widely spread the readings are (ideally, the standard deviation of the readings should be zero). The higher the Cpk, the better is the capability of the process to meet its requirements.
In the industry, a Cpk of less than 1.66 needs a closer look. A Cpk that’s less than 1.33 needs some action to make it higher, and a Cpk of less than 1.0 means that the process is not capable of meeting its requirements.
A low Cpk means one of three things: the mean is far from the center of the specs, or the standard deviation of the readings is high (i.e., the readings are widely spread), or both conditions exist.
New Mountz Trade Show Booth Displays Industrial Quality Torque Tools Designed to Improve Productivity.
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.
The new trade show booth design, provided engineers easy access and viewing of the various Mountz products on display. This included torque analyzers, torque testers, torque sensors, torque wrenches, electric screwdrivers, pneumatic screwdrivers, torque screwdrivers, torque multipliers, assembly tools, pulse tools, screw counters, tool balancers and other torque tools.
While many exhibitors at the Assembly Technology Expo experienced a decline of up to 20% in booth attendance, Mountz saw a 50% increase in attendees visiting the new booth display and new products. Read the rest of this page »
