Houses have doors, and parts have indentations, through-holes and other features that don’t point straight up or down and could act as undercuts in a two-part mould. Designers using rapid injection moulding can address these challenges in a variety of ways, including side-action cams, sliding shut-offs, pick-outs and bump-offs, as discussed in this article from Proto Labs.
This application note from Linear Technology describes a number of enhancement circuit techniques used with existing three-terminal regulators that extend current capability, limit power dissipation and more.
As this article in the ‘Mike Might Know’ series from Sherborne Sensors explains, military organisations around the world are increasingly relying on advanced sensor technologies to improve the effectiveness of their weaponry, protect personnel, deliver other enhanced capabilities and reduce cost. The scope of applications for inclinometers within military platforms is extensive.
This technical article from Linear Technology presents analogue-to-digital conversion circuits that directly digitise low-level transducer outputs, without DC pre-amplification. It also covers circuits that operate with thermocouples, strain gauges, humidity sensors, level transducers and other sensors.
Many factors affect the cosmetic appearance of injection-moulded plastic parts. Some of these are within the control of the part designer and some are not. In this white paper, Proto Labs describes several factors affecting cosmetic appearance, the interactions between those factors and steps the designer can take to improve final appearance.
There is no doubt that readers of trade magazines have remained keenly interested in the advantages to be found in process cleaning, while being confused by the amount of misinformation that seems to be forever presented to them. There are two reasons for this: an intention to mislead or simply a lack of understanding of the subject. In this article, Envirotech Europe discusses the importance of doing your research when choosing which products to use.
Apart from its originally intended purpose for strain measurement, the metallic resistance strain gauge is extremely commonplace in transducer applications. Its low cost, high accuracy and ease of application make it an ideal transduction element and it is widely used in pressure, load, force, torque and displacement transducers. However, this article in Sherborne Sensors’ ‘Mike Might Know’ series focuses on semiconductor strain sensors.
In order to handle the complexities of contamination on an operative’s clothing and skin, there is an argument to suggest that just the recommended ANSI Z358.1 standard of 15 minutes of dowsing time may, in many cases, not be long enough. This article discusses the benefits of bespoke units, which guarantee 30 minutes of tepid water, notwithstanding the extreme climatic conditions in which safety showers are sited.
In its extreme form, liquid silicone rubber (LSR) can withstand constant temperatures of up to 316°C and intermittent temperatures of 371°C. To those more familiar with ordinary thermoplastics, it may seem counterintuitive that such a rubbery material can be used in high-temperature applications, but LSR is actually made to take the heat.
If you work with industrial chemicals, materials or solvents then you may have heard of the American Conference of Governmental Industrial Hygienists (ACGIH). The ACGIH is a scientific, but non-governmental body of industrial hygienists that publishes Threshold Limit Value (TLV) opinions on chemicals such as n-propyl bromide, the base solvent for EnSolv formulations. These TLV opinions are not held to the same standards as limits set by an organisation such as OSHA in the US, but are ...
In this quick-reference guide for engineers and designers, Proto Labs explains the processes of injection moulding and rapid injection moulding. The company also describes the applications of rapid injection moulding and explores several other considerations.
Organisations that improve the resource management and capacity planning of their people are significantly reducing their top pain points and positioning themselves to better capitalise on business opportunities. This is the main conclusion of the 2014 State of Resource Management and Capacity Planning Report, commissioned by Planview and conducted by Appleseed Partners and Dig Market Research. This infographic presents the findings.
Day-to-day activities, such as carrying out maintenance or emergency repairs, commissioning new equipment or conducting on-site checks, need to be simplified because of the reduction in personnel and increase in workload. As this guide from GE Measurement & Control explains, use of the most advanced on-site instrumentation is imperative in order to maintain and calibrate today’s intelligent, high-precision equipment; this aspect applies to all process applications.
Continuous, in-line measurement of asphalt-rubber (A-R) viscosity provides a new window into the A-R process. This measurement can assure the binder is not under- or over-reacted, that dosing is precise, and that the processing system is performing to specification. In automatic blending control systems, viscosity measurement can be used as the process variable around which temperature, heating time, mixing time and the addition of additives can be controlled. This technical article ...
Industrial automation companies and high-end equipment manufacturers throughout Europe seek opportunities to expand their business interests by moving into high-volume markets. Faced with continuing uncertainty about the future of the euro, many companies are looking with growing interest at the expansive industrial and manufacturing markets in Asia, especially those in China — the world’s fastest-growing economy.
