A Case for Extensometry

A universal testing system very simply measures 2 things during a basic mechanical test: force (via the load cell) and displacement (via the crosshead encoder). To obtain a basic stress-strain curve, you might think that’s all you need. With the force measurement from the load cell, the cross-sectional area of the material can be used to calculate stress; and with the crosshead extension, the original distance between the grips or fixtures can be used to calculate strain throughout the test. How simple!

Question From a Customer: Air Bubbles in Extrudate

Q: We have an MF30 Melt Flow Indexer and started running tests on various polymers in our lab. Some of the samples have a lot of air bubbles in them. I believe this is contributing to inconsistencies in melt flow values. How do we minimize this? A: There are a lot of reasons you could be seeing air bubbles in the filament sample. Ultimately, it comes down to keeping the testing and cleaning processes as consistent as possible.

Understanding Melt Flow Testing and Its Importance

Melt flow testing is simply a measure of the flow of a polymer when melted. The result of a melt flow test, called the melt mass-flow rate (MFR) or melt volume-flow rate (MVR), is defined as the amount of mass or volume of a polymer that flows through a small die at a specified temperature and pressure.

Preloading, and How It Affects Your Mechanical Test

It is almost always recommended that the Bluehill® Software preload feature be used when you’re performing a mechanical test. Preloading simply removes slack from the load string before a test begins.

Quick Tips for Balancing Load Cells

Whether you use bathroom scales, digital kitchen scales, spring scales – or any other measuring instrument, for that matter – you know the importance of zeroing it before it’s used. Failure to do so results in a shift in weight and thus, an incorrect reading on the scale. Now let’s think about the load cell in your testing system, which is just like a scale …

Are You a Statistic?

According to the Center for Disease Control and Prevention, motor vehicle crashes are the leading cause of death in the US among people ages 5-34. About 6,400 adults are injured in motor vehicle accidents every day. Still, nearly 15% of us don’t buckle up for every trip we take in our cars.
