The Occupational Safety and Health Administration (OSHA) is an agency of the United States Department of Labor, and it is responsible for ensuring that employers provide safe and healthful working conditions for employees in the U.S. One of the ways OSHA accomplishes its mission is by setting and enforcing standards.
OSHA standard 29 CFR 1910.95 relates explicitly to occupational noise exposure. This standard protects workers from excessive noise levels that can lead to hearing loss or other health problems.
Sound level indicators (often called sound level meters or SLMs) and dosimeters are two primary instruments used to measure occupational noise levels. Both devices help employers assess noise exposure and ensure compliance with OSHA's 1910.95 standard on occupational noise exposure.
Compliance with OSHA 1910.95:
In summary, while sound level meters provide immediate spot readings of noise levels, dosimeters assess an individual's cumulative exposure over time. Both tools are essential for comprehensively evaluating workplace noise and ensuring compliance with occupational noise standards.
When external loads are applied, stress analysis assesses the internal forces and stresses acting on a material or structure. Strain gages, widely used in this process, measure the deformation (or strain) that occurs when a material experiences stress. The following provides a detailed explanation of how to accomplish stress analysis using strain gages:
In summary, stress analysis using strain gages requires selecting, installing, calibrating, applying external loads, collecting data, and analyzing the stress-strain data to understand the material's response to the applied loads.

This video demonstrated how to clean parts, in this case pressure sensors, using the PolyClean fluidized temperature bath.
Dynisco’s PolyClean is a fluidized temperature bath that will clean parts and tooling 2 to 3 times faster and safer than traditional cleaning methods, such as ovens. Dynisco’s fluidized bath system is air¬controlled with advanced PID temperature controller for optimal thermal performance. The system uses aluminum oxide sand (heated up to 1112°F) and air to surround the part or tooling. The “sand” will gently breakdown the polymer without damaging the part or tooling.

The Dynisco PolyClean Fluidized Temperature Baths come in three models and offer a cost-effective, fast, and safe way to clean various plastic processing components. PolyClean Fluidized Temperature Baths are applied in any polymer manufacturing or laboratory facility that needs minimal operator interaction and a low risk of harm to essential design requirements of a part during the cleaning process.
The PolyClean 6L Fluidized Temperature Bath is ideal for cleaning small tooling from laboratory extruders or injection molding machines.
The PolyClean 12L cleans extrusion tooling and other forms of hardware, forms parts, calibrates and tests various sensors and systems, heat treats metals and heats reactors, coils, flasks, and containers.
The 26L PolyClean has similar functions and benefits to the PolyClean 12L, but its 26" deep basket allows it to clean larger components than the PolyClean 12L

AP Corp.Industrial-grade screw and barrel wear cuts throughput speeds, producing scrap before shutting down. For the first time, technology is making progress in unraveling the mystery of screw and barrel wear.
There has been a lot of injection molding machine innovation in the past year. And now, Glycon Corp. has the technology to test wear within the plasticating device. Glycon is in the first phase of rolling this technology out in the industry. It will concentrate on extrusion and blow molding.
With this capability, they have developed the technology to calculate the rate of wear and predict future wear. This data determines the most cost-effective time to replace these components.
Glycon has been working on measuring wear since 1986 gained their first patent as Great Lakes Feedscrews. The company expanded the invention to include measuring barrel wear and was awarded additional patents in 2006, 2007, 2008, and 2019.
Wear and tear challenges are well documented over the years, and plastic processors know the symptoms. Many machine operators compensate by making changes to the screw speed or temperature settings. The problem is, both of these changes would ultimately result in lower efficiency and higher scrap rates.
The new system called EMT (short for Electronic Measurement and Tracking), includes Glycon's flite-scan eddy-current sensors mounted in one or more positions within a SmartBarrel. These barrels also have SmartPorts, another innovative technology offered by Glycon.
Measurements will be conducted routinely at the processor's plant by field technicians using a Flite-Scan sensor. Several eddy-current sensors were tried over the years. Multiple sensor manufacturers were collaborated with, but all ran into failure at high temperatures in the plasticating units.
Micro-Epsilon, a leading manufacturer of sensors that measure displacement, distance, position, vibration, dimension and thickness, was the eventual choice because their sensors proved much more robust and provided reliable readings up to 600 F.
The EMT system is not only to analyze the data to determine the optimum time to replace or repair worn screws or barrels to optimize productivity but also to relate the wear to:
The Glycon EMT system's advantages are that it provides precise measurement of the wear on the OD of the feedscrew and the barrel's ID and its simplicity and cost-effectiveness. It allows maintenance personnel to plan to measure intervals and to schedule changeouts at convenient times based upon wear-rate data rather than 'running to failure' and having to run inefficiently or not at all.

The BT Series shakers from Sentek Dynamics are designed for demanding vibration test applications. Typical applications included structural analysis, calibration and testing of smaller assemblies. The BT-100 through BT-400 shakers utilize light weight rare earth magnets in lieu of traditional Alnico magnets. The use of these magnets decreases the total shaker mass to a third of similar size system, making these shakers easy to handle and portable.
The systems range in size from 100 N (70 lbf) to 1000 N (224 lbf). Systems 400 N (99 lbf) and smaller are permanent magnet shakers and use lightweight rare earth magnets, making these systems easy to handle and portable. There are three versions of the BT Series of shakers: the BT, BT-M and BT-MTH.
The BT Series is recommended for vibration testing of small assemblies and components. These shakers have armature diameters from 60 mm (2.36 in.) to 120 mm (4.72 in.). The BT-1000 is equipped as standard with Automatic Armature Centering (AAC) and Air-Isolation Feet (AIF).
The BT-M and BT-MTH Series are our modal shakers lines. BT-M will use standard stingers while the BT-MTH is our through-hole version. On the 100 N and 200 N system the BT-MTH offers over double the displacement. The BT-MTH Series allow you to use piano-wire stingers. The BT-1000-M is ideal for the structural and modal analysis of high-mass structures. The addition of ZPR (electronic zero-point regulation and adjustable suspension stiffness) allows the user to pre-load the structure prior to applying a dynamic load.
The new Sentek Dynamics Bench Top and modal exciters are based upon years of practical experience. These systems all exhibit a high lateral stiffness and high force-to-weight ratio. They are specifically designed to help ensure the best possible performance with minimum setup time.
