The Importance of Calibration

Keeping your force or torque measuring instruments properly calibrated is critical to ensuring the quality of your manufactured material, component, or assembly. Although such instruments in many cases do not drift out of their accuracy specifications for lengthy periods of time, calibration is recommended at least once per year to ensure accuracy. In cases of heavy use, more frequent calibrations or verifications can be appropriate.

At Mark-10, we have a fully equipped climate-controlled calibration laboratory. With our US and European service centers, we provide quick turnaround. When gauges and sensors are sent back to our main US facility, we provide a NIST-traceable certificate of calibration. We can also provide a certificate of calibration with data which lists 10 data points in each direction (tension/compression or clockwise/counter-clockwise). As found/as left data can also be supplied upon request.

For customers requiring certificates of calibration to the ISO 17025 standard, we can provide such calibrations via a partner laboratory, as well as through many of our distributors. If sending an instrument to us, please request an RMA number before doing so, and include a printed copy of our RMA form in the box.

Growth in the Sustainable Packaging Market

As consumers become more environmentally conscious the demand for sustainable packaging is expected to grow. A new report from Smithers Pira forecasts that the market will reach $244 billion by 2018 with large growth in paper packaging, followed by metal, glass, and plastic.

In addition to consumers, governments are also calling on manufacturers to become sustainable concepts to reduce, reuse, and recycle. Companies like Unilever are already making this move with the launch of its Dove Body Wash bottles, which will contain at least 15% less plastic. The bottle will use MuCell Technology for Extrusion Blow Molding and uses gas injection to create gas bubbles in the middle layer of the plastic bottle which will reduce the density of the bottle and thus the amount of plastic required.

To help packaging companies ensure that their sustainable packaging still holds up to regulations and consumer expectations, Mark-10 offers a full range of force and torque measurement products. Configure a system to address applications such as cap opening force, cap torque, top load, peel, burst, compression, and many others.

New FDA Proposal to Expedite Approval Process for Medical Devices

At Mark-10 we’re always closely watching medical device trends and recently the FDA has proposed a new program to help speed up the approval process for devices that treat or diagnose patients with serious conditions whose needs aren’t met by current technology.

The new program would have more interactive engagement with FDA staff and unlike other existing programs, this one focuses on reducing the time associated with product development and not just reducing the time to market.

According to the FDA, to be eligible for participation, a medical device must:

“Be intended to treat or diagnose a life-threatening or irreversibly-debilitation disease or condition, represent one of the following:

1.       No approved alternative treatment/diagnostic exists, or

2.       A breakthrough technology that provides a clinically meaningful advantage over existing technology, or

3.       Offers a significant, clinically meaningful advantage over existing approved alternatives, or

4.       Availability is in the patient’s best interest

And have an acceptable data development plan that has been approved by the FDA.”

At Mark-10, we’re happy to play a helping role for medical device manufacturers to meet their quality objectives. Our line of force and torque measurement systems may be used for numerous applications, including fastener torque, needle sharpness, catheter torque, tube terminal pull tests, peel testing, tensile testing, and more.

Manual vs. Motorized Test Stands

At Mark-10, we offer a range of force and torque measurement test stands to suit a variety of applications, including manual and motorized options.

Our manual test stands allow users to reduce variability inherent in hand testing by properly aligning a force gauge and grips or fixtures.  Manual test stands are an ideal option for budget-minded applications that require a bit more consistency than hand operated tension or compression force measurements.

For the most consistency between tests, a motorized test stand’s programmable speed is an ideal solution. Such stands can also be fitted with an internal scale for displacement measurement, be controlled by a PC, and perform a number of automated functions, thereby increasing testing efficiency and throughput. Our motorized stands can perform a wide range of compression and tension test applications. When fitted with an appropriate force gauge, output of force vs. time or force vs. distance via USB is possible.

Manual and motorized test stands are available in several force ranges up to 1,500 lbF (6.7 kN). We supply an extensive selection of grips and fixtures, serving the medical device, automotive, packaging, and many other industries. To learn more about each of our manual and motorized test stands use our test stand comparison chart to find the one that works best for your applications.

Nordic Ultratune Case Study: Measuring Flex Force

Nordic Ultratune, a cross-country ski dealer and service center located in Winthrop, WA, has been using the Mark-10 Model ES30 manual test stand and the Model MG200 force gauge to offer customers specialized tuning and configuration services. By using the force measurement products, Ultratune is able to conduct a flex analysis, which measures camber length and height with pressure applied approximately at the ball of the foot. The results can help Nordic Ultratune identify the characteristics of the skis and how well they are matched. Additionally, the test can apply pressure at approximately the mid-foot to help determine the best type of wax: power, warm hardwax, or klister.

The force measurement products also help Nordic Ultratune conduct a skate ski flex analysis which measures camber length and height with pressure again applied 8 cm behind the balance point that approximates pressure at the ball of the foot. The results allow the company to see the flex characteristics of the skis, how well they are matched, and can be used to characterize a pair of skis a customer already owns if they wish to match with another pair. It can also help identify skis that are too soft or too stiff.

Engineering Students Get a Boost in Support of NASA HUNCH Experiment Series

Under normal conditions, determining the mass of an object is a simple affair; you place the object on a scale and it tells you the mass. But in a zero gravity environment like outer space, things get a little complicated. To make the process easier, engineering students at the Tri-County Regional Vocational Technical High School (RVTHS) in Franklin, MA have been taking part in the High School Students United with NASA to Create Hardware (HUNCH) program to find a solution. The program gets students involved in the creation of hardware designed to meet the unique needs of those working at the International Space Station.

To help the students meet their objective, Mark-10 Corporation donated two Series 7 digital force gauges for use in their innovative measurement system. The system involved the two force gauges being mounted to a spinning platform. An object of known mass was attached to one of the gauges, while an unknown mass was attached to the other. By calculating the ratio of the two centripetal force measurements, the students could determine the unknown mass. The system is aptly named the “Zero Gravity Scale.”

With their scale prototype complete, the students took it aboard the NASA Zero Gravity Plane in Houston, Texas for a realistic simulation. Now, they are looking into the next phases of research, creating a smaller design for use on the International Space Station.

To further support these NASA HUNCH student endeavors, Mark-10 donated two miniature Series R04 force sensors. These instruments offer tension and compression measurements in tight environments, which is important in this field of work. We take pride in being able to help budding engineers create devices that will advance aerospace exploration.

To see the research put to work, watch a video of the Tri-County RVTHS students testing their Zero Gravity Scale (in zero gravity!) on YouTube.
