Attachment Overview

An attachment is a jig that is attached to a test stand or a test stand of a force gauge. Since it is the part of the attachment that actually contacts the sample to be measured, the attachment is a very important element in force measurement.

A force gauge can be used to measure compression force by attaching an attachment for compression test, and can measure tension force by replacing it with an attachment for tension test. In other words, a force gauge can read a force value, but the type of force to be measured is determined by the attachment, not the force gauge.

Even for a single compression test, there are various types of compression tests, such as a pressure test in which a force is applied to the entire test sample, or a puncture test in which a force is applied locally.

In order for a force gauge to properly measure your desired force, you need an attachment that is suitable for the purpose. It would not be an exaggeration that "the right attachment" is the most important factor in force measurement. Therefore, IMADA has continued to develop attachments to meet the measurement needs of our customers, and the number of types of attachments has been continuously increasing. We have reached the point where we offer over 230 types attachments as regular items.

Together with custom-made attachments, we manufacturer more than 300 types of attachments annually. The possibilities for force measurement is infinite, and the world of attachments is endlessly wide and deep, although it may seem small and inconsiderable.

How Best to Select Attachment

There are four points to consider when selecting attachments.

1)Type of force. Force types are broadly divided into compression, tension, peel, and friction. Be distinctive about the type of force you want to measure.

2)Shape and material of the sample. For example, even if the type of force is determined to be a tension, the attachment for gripping the sample will inevitably differ between a long, thin sample such as wire and a thin, flat sample such as film. Furthermore, even with the same wire shape, the optimal gripping method differs depending on whether the sample is elastic or not, how smooth (slippery) the surface is, and how easy it is to cut.

3)Priority in measurement. Even if the shape and material of the sample to be measured are the same, the selection will vary depending on what is important in the measurement, such as a one-touch fixation type when the top priority is measurement efficiency, or a screw fixation type when the degree of fixation needs to be adjusted manually depending on the sample.

4)Force value. Each attachment has a maximum allowable force value. We recommend an attachment with a slightly higher allowable force value than the force value expected to be required for the measurement. Also, since the weight of the attachment itself is recognized as a force by the force gauge, it is important that the weight of the attachment should be within 10% of the maximum allowable force value of the force gauge.

If you are still uncertain about the test type, or the force value, contact us for sample measurement services or online meeting for free.

Tips for more skillful use of Attachments

Attachments should not be underestimated. For example, the GCF series of chuck jigs allows you to easily replace the claw by yourself, and a variety of optional claws are available. If you have a spare claw, you can replace it immediately in case the claw wears out. If you have many samples to measure, having different claws available allows you to perform various measurements with a single attachment.

We offers accessories for attachments to improve the efficiency and quality of measurements. An adapter that makes it easy to attach and detach an attachment to a force gauge, a table for attachments that makes it easy to center a test sample, and other attachments that help improve measurement efficiency are among a few examples. There are also adapters with free joints to adhere to the measurement sample and prevent unbalanced load, as a way to help improve repeatability.

Some attachments conform to JIS, ISO, and other industrial standards. Measuring in a way that conforms not only to in-house standards but also to the standards of independent organizations is complex, but it may provide you a competitive edge. When you consider industry standards-compliant measurements and discover the standard products cannot be applicable, rest assured because we offer custom-made attachments as well.

Regarding custom-made, it is possible not only to conform to standards, but also to change the size and specifications of standard products. Since semi-custom orders based on standard products can be less expensive, we prioritize the process of quasi-custom orders first.

It isn’t too much exaggeration to say that mastering the use of attachments means mastering force measurement.
