Elevate Plastics Quality with Kawasaki Precision Gear Pumps

Kawasaki precision gear pumps deliver constant, high-pressure, positive-displacement flow tailored for demanding plastics applications. Engineers machine hardened alloy gears to sub-micron tolerances inside robust cast-iron housings. As the drive shaft spins, gear teeth trap molten polymer at the inlet and drive it through the outlet port in a steady, pulsation-free stream. That precise action ensures repeatable volumetric displacement, so injection molders and extrusion specialists hit their targets every cycle.

In injection molding, technicians dial in shot weight and cavity fill rates by adjusting pump speed. Kawasaki pumps sustain volumetric efficiency at pressures up to 5,000 psi, helping molders control melt-front velocity, reduce flow-line defects, and eliminate sink marks. When processors switch from polypropylene to glass-filled nylons, the pumps adapt instantly to viscosity shifts and temperature swings. That reliability underpins dimensional accuracy in high-precision parts such as medical device housings, optical lenses, and microfluidic components.

Extrusion lines benefit equally when Kawasaki gear pumps isolate screw speed from die pressure. Placing a pump downstream of a twin-screw extruder lets operators suppress melt surging and stabilize downstream film, sheet, or pipe production. Programmable drives let floor engineers tweak flow rates on the fly, maintaining throughput within a few percent of setpoints during long production runs. Plants see fewer temperature spikes and extended screen-pack and die life by decoupling metering from melt generation.

Filled or abrasive resins pose a serious wear challenge, but Kawasaki gears resist scoring and fatigue. Their carburized or nitrided surfaces and replaceable hardened bushings stand up to glass fibers, mineral fillers, and regrind. Thanks to a pull-apart housing design, maintenance crews swap gear sets, seals, and bearings in under an hour. That quick service cuts downtime, minimizes scrap, and boosts overall equipment effectiveness.

Process automation teams integrate Kawasaki pump drives with PLC and SCADA systems to continuously capture flow, pressure, and temperature data. Analysts mine that trace data to refine processing recipes and schedule predictive maintenance before wear impacts quality. When a pump drifts outside tolerance, software triggers alarms and auto-adjusts parameters, protecting against off-spec production and unplanned stoppages.

Plastics processors around the globe have improved part consistency, tightened tolerances, and extended equipment life by deploying Kawasaki precision gear pumps in molding and extrusion operations. They trust these pumps to uphold the exacting standards of packaging, automotive trim, medical devices, and flexible films. Kawasaki precision gear pumps stand represented in New England by Andruss Peskin Corp. (AP Corp.), providing regional application expertise, technical training, and rapid aftermarket support to keep every pump performing at peak precision and reliability.

Industrial Infrared Temperature Measurement

Industrial infrared temperature measurement has revolutionized how professionals monitor heat in countless processes, from heavy manufacturing to delicate laboratory work. Optris, a global leader in this field, develops infrared thermometers, pyrometers, and thermal imaging cameras that quickly capture accurate temperature data from a safe distance. These instruments rely on the principle that every object above absolute zero emits infrared radiation. The amount and spectrum of this radiation change with temperature, allowing IR sensors to convert the captured energy into precise temperature readings.

Engineers often use the concept of blackbody radiation to explain infrared temperature measurements. Objects at different temperatures emit characteristic infrared wavelengths, and specialized detectors translate those wavelengths into voltage signals. Optris calibrates its devices using reference temperatures to ensure high accuracy and repeatability. Their IR thermometers and pyrometers focus on a specific spot and measure the IR emission from that region. At the same time, their infrared cameras gather information from a wider field of view to generate complete thermal images.

Many industries value these non-contact measurement tools because they deliver almost instantaneous feedback. Manufacturers of glass, metals, and plastics rely on Optris sensors to monitor extreme temperatures in continuous production lines. The glass industry often measures the surface temperature of molten glass and cooled products to detect anomalies and maintain product uniformity. Metal processors benefit from real-time heat monitoring during forging or heat treatment, improving product quality and conserving energy. Plastic molding requires close observation of part and mold temperatures to prevent warping and to ensure a consistent finish.

Optris cameras also help technicians spot thermal irregularities in high-density electrical systems. Overheating circuit boards or power modules are bright hotspots in a thermal image, and operators can intervene immediately to avoid failures. In 3D printing, engineers watch the temperature distribution on layers of molten material to refine the printing process and create more substantial final parts. Optris sensors also appear in fire safety applications, where early detection of elevated temperatures in waste disposal sites or bulk storage areas gives operators a head start in preventing catastrophic fires.

Infrared technology is valuable because it measures temperature without disturbing the target material. Operators minimize downtime by diagnosing issues or optimizing processes without shutting down equipment. The versatility and reliability of Optris devices reflect years of dedication to thermal measurement research and development. Industrial customers trust these products to help them reduce costs, enhance quality, and maintain safer work environments.

High-Speed Color Measurement for Modern Manufacturing

Understanding how high-speed spectrometers measure color on manufacturing assembly lines provides a glimpse into the complex world of precision quality control and modern manufacturing techniques.

A spectrometer measures the amount of light absorbed or transmitted across different wavelengths. Color measurement involves analyzing the spectrum of light reflected off an object to determine its color.

In a typical setup on a manufacturing assembly line, a light source illuminates the product or material whose color we want to measure. This light source must remain consistent in its intensity and spectrum because any variation can influence the accuracy of the color measurement.

When the light hits the object, the object absorbs specific wavelengths of light and reflects others. The reflected light then enters the spectrometer. Inside the spectrometer, the light is dispersed, often with the help of a diffraction grating or a prism. This dispersion breaks the incoming light into its constituent colors or wavelengths, similar to a rainbow when sunlight passes through raindrops.

An array of detectors inside the spectrometer captures this dispersed light. Each detector is sensitive to a specific wavelength or a narrow range of wavelengths. By measuring the intensity of light each detector receives, the spectrometer builds a spectrum – a graphical representation of light intensity versus wavelength.

This spectrum effectively captures the color profile of the object, and a computation derives color values, typically regarding color spaces or systems like the CIELAB or RGB. These values provide a quantitative measure of the object's color compared to a standard or reference value.

In a manufacturing assembly line, the speed of this process is paramount. High-speed spectrometers capture and process data in real-time, allowing them to analyze the colors of objects as they race along the line. Suppose the color of a particular product deviates from the set standard. In that case, the system can instantly flag it for inspection or removal, ensuring that products maintain a consistent color quality throughout the production run.

The integration of high-speed spectrometers into manufacturing lines, coupled with sophisticated software, ensures that color consistency and quality meet the strict standards demanded by today's consumers and regulatory bodies. This method not only optimizes the quality of the final product but also minimizes wastage and enhances efficiency in production processes.

Micro-Epsilon stands as one of the top sensor manufacturers globally. For over 50 years, they have consistently provided reliable and high-performance solutions, especially in situations demanding high precision measurement or inspection. Their product line includes sensors for distance and displacement measurement, IR temperature measurement, and color detection, along with systems for dimensional measurement and defect detection.

The Micro-Epsilon colorCONTROL ACS7000, color measurement system, recognizes reference colors through direct comparison and distinctly identifies individual colors based on their coordinates in the color space. Equipped with a high-speed spectrometer, the colorCONTROL ACS7000 excels in applications that require online examination of colors and shades with utmost precision.

From Spot Checks to Cumulative Assessments: Understanding Noise Measurement Tools for OSHA 1910.95

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. 

1. Sound Level Indicators (Sound Level Meters - SLMs):

• Function: An SLM measures sound pressure levels in the workplace. It provides instant readings of noise levels at a specific location and time.
• Usage:
• SLMs spot-checks or short-term measurements in specific areas or at particular workstations where noise levels might be a concern.
• They can identify areas in the workplace where further noise monitoring or controls may be necessary.
• When using an SLM, it's crucial to consider the weighting scale (typically "A" weighting for human hearing) and the response time (slow or fast).
• Data Collection: SLMs provide a snapshot of the noise level during measurement. They don't offer cumulative exposure data over time. Therefore, while SLMs can determine if a particular location is loud, they don't indicate the length of exposure to that noise level.

1. Dosimeters:

• Function: Dosimeters are wearable devices that measure a worker's cumulative noise exposure over time. They provide a personal noise dose reading based on the intensity and duration of sounds for individual exposure.
• Usage:
• Dosimeters are typically clipped to a worker's clothing and worn throughout the workday. The microphone is usually positioned near the worker's ear to assess the noise exposure accurately.
• They benefit workers who move between different areas or tasks, resulting in varying noise exposures.
• Data Collection: Dosimeters continuously measure and record noise levels, providing a time-weighted average (TWA) over the period worn. This data is crucial in determining worker-level exposure exceeding permissible exposure limits (PEL) set by OSHA or other regulatory bodies.

Compliance with OSHA 1910.95:

• Employers typically start with sound level meters to identify areas or tasks with potentially hazardous noise levels.
• Employers will use dosimeters to monitor individual exposures over the work shift if areas show elevated noise or workers' tasks involve moving between varying noise environments.
• Suppose the noise levels exceed the action level (typically 85 dBA TWA over 8 hours). In that case, the employer must implement a hearing conservation program, which includes further monitoring, audiometric testing, training, and provision of hearing protection.

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.

Optimizing PCB Testing with the Latest 3-Element Stacked Rosette Strain Gauge Technology

As the demand for thinner, smaller, and more densely populated PCBs increases, Micro-Measurements' new G1350A perfectly fits the bill for evaluating PCBs' stress. Thanks to the flex circuit and pre-attached lead wires, it features a compact design and significantly simplifies the installation process.

A stacked rosette strain gauge is a particular strain gauge designed to measure the typical strains along different directions at a single point. A regular strain gauge measures the deformation or strain of a material in one direction. In contrast, a rosette strain gauge, composed of multiple strain gauges, can measure strain in multiple directions. A stacked rosette strain gauge consists of several individual strain gauges stacked on each other, each oriented in a different direction to measure the strains in various directions at a single point. The stacked rosette configuration allows for a more compact design compared to a planar rosette, where the gauges are arranged next to each other.

Usage on Printed Circuit Boards (PCBs):

• Quality Control: During the manufacturing of PCBs, there may be internal stresses generated due to various processes such as lamination, soldering, etc. These stresses may lead to the PCB's warping, bending, or even cracking. Stacked rosette strain gauges can measure these internal strains at critical points on the PCB to ensure they are within the permissible limits.
• Design Validation: During the design phase of PCBs, engineers use finite element analysis to model and predict the strains and stresses that the PCB will be subjected to during its operation. By attaching stacked rosette strain gauges to the prototype PCBs and subjecting them to real-world operating conditions, engineers can measure the actual strains experienced by the PCB and compare them with the predicted values from the model, helping in validating the design and making any necessary modifications before mass production.
• Failure Analysis: When a PCB fails during operation, it is essential to understand the cause of the failure to make necessary design modifications and prevent similar failures in the future. Stacked rosette strain gauges can be attached to the PCB at locations suspected of experiencing high stresses or strains. By subjecting the PCB to the operating conditions that led to the failure, engineers can measure the strains at these critical points and determine if they were the cause of the failure.
• Thermal Expansion Measurement: PCBs often have components that generate heat during operation, which can cause thermal expansion of the material. This thermal expansion can lead to mechanical stresses and strains on the PCB and its components. Stacked rosette strain gauges can measure these strains accurately and help design PCBs that can withstand these thermal expansions without failure.

Micro-Measurements' G1350A Features:

• Round shaped to facilitate spot installation.
• Minimal form factor of 5.1mm diameter.
• Readily available resistance values: 120 ohm (C4A) + 350 ohm (C4K).
• Flex circuit connection for the most flexible and comfortable gage installation (50mm and 300mm).
• Pre-attached lead wires: 1m or 3m length, 2 or 3 wire configuration.
• Highly compatible with StrainSmart® software for PCB testing application features.

Load Cells: The Vital Component in Precision Weighing

A load cell is a transducer or a sensor that converts force into an electrical signal. In industrial weighing applications, it's a critical and core component used to measure weight or force.

The most commonly used types of load cells in industrial applications are strain gauge load cells, which work on the principle of piezoresistance. When a load or force is applied to the strain gauge, it deforms or changes shape. This change in shape causes a measurable change in the electrical resistance. The change in resistance is proportional to the load applied, meaning the more significant the load, the larger the change in resistance.

This change in resistance is usually minimal, so it's converted into an electrical signal using a Wheatstone bridge configuration. The signal is then amplified and converted into a digital form by an analog-to-digital converter. This digital signal can be interpreted and displayed on a readout device, such as a digital display or a computer.

In industrial weighing applications, load cells are ubiquitous, with applications including weighing scales, industrial scales, batching scales, and load-testing machines. They can measure loads ranging from tiny (a few grams) to large (hundreds of tons).

Load cells are robust and reliable, capable of withstanding harsh industrial environments. They can handle extreme temperatures, high levels of vibration, and other challenging conditions. Additionally, they offer high precision and accuracy, which are critical in many industrial applications.

In addition to their use in weighing, load cells measure tension, compression, and shear forces, making them versatile tools in many industrial processes. They play a significant role in quality, inventory, and process control in various industries, including manufacturing, agriculture, food processing, pulp & paper, power generation, transportation, and construction.

BLH Nobel is a leading weighing and force measurement solution provider, including load cells, weighing modules, and process control equipment. The company is renowned for delivering precision, reliability, and durability, particularly in harsh industrial environments.

KIS Weigh Modules, adeptly deployed on dynamic process vessels amidst harsh, sanitation-intensive areas, have mastered the art of thriving amidst grime and grit. Their performance remains uncompromised and exceptional, even in the most challenging conditions riddled with corrosive acids, potent industrial cleaning agents, acidic vapors, and abrasive granulated powders.

Part of the remarkable performance of the BLH Nobel KIS is its ingenious cylindrical design. KIS beams can be maneuvered within the module's infrastructure, aligning precisely with the direction of the applied weight. The modules feature cylindrical, electro-polished stainless steel, forming an almost friction-free surface, allowing the module yoke to glide effortlessly during thermal expansion and contraction periods.

Stress Analysis With the Use of Strain Gages

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:

1. Selecting strain gages: The first step involves choosing an appropriate strain gage for the specific application. Consider factors such as the type of strain (e.g., tensile, compressive, shear), the expected magnitude and direction of strain, temperature range, and material properties of the test specimen.
2. Preparing the surface: Before attaching the strain gauge, clean and thoroughly prepare the test specimen's surface, using solvents, abrasives, or other cleaning methods to remove contaminants, ensuring proper strain gage adhesion to the surface.
3. Installing strain gages: Bond the strain gage to the test specimen using a specialized adhesive. Align the gage carefully toward the expected stress, accurately positioning the gage grid (which contains the sensing elements) over the area of interest. Once the adhesive cures, the strain gage installation is complete.
4. Wiring and instrumentation: Connect the strain gage to a data acquisition system using lead wires. This system usually includes a signal conditioner, which amplifies the small electrical output from the strain gage, and an analog-to-digital converter, converting the analog signal into digital data for further analysis.
5. Calibrating: Calibrate the strain gage and data acquisition system before starting the stress analysis. Apply known loads or strains to the test specimen and record the corresponding output from the strain gage. Create a calibration curve relating the measured strain to the electrical output of the gage.
6. Applying loads and collecting data: With the strain gage installed and calibrated, subject the test specimen to the desired external loads. As the sample deforms under load, the strain gage also deforms, causing a change in its electrical resistance. This change in resistance is proportional to the strain experienced by the material and can be measured and recorded by the data acquisition system.
7. Analyzing data: Analyze the collected data to determine the stress experienced by the material. Typically, this involves comparing the measured strain to the material's known stress-strain relationship (e.g., elastic modulus). Depending on the complexity of the loading conditions, finite element analysis (FEA) or other computational methods may be employed to simulate the stress distribution within the specimen.
8. Interpreting and concluding: Use the stress analysis results to evaluate the material's performance and assess the design's suitability for the intended application, including identifying potential failure points, assessing fatigue life, or optimizing the design to reduce stress concentrations.

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.
