Dynamic Pressure Controls
Pressure controllers from Clippard, Cincinnati, OH, use proportional valves, allowing for steady, accurate, and repeatable downstream pressure control as demand or process changes. The Cordis CP1 single-valve dynamic pressure controls provide a precise linear pressure control within a closed-loop system. Once a command is increased, the proportional valve opens up to allow supply pressure to pass over the sensor element, which provides an active feedback for the microcontroller to satisfy the set point in the process. If the sensor detects a value higher than the set point, the proportional valve closes and allows process to consume the remaining downstream pressure.
Premio, Los Angeles, CA, has added a new AI processor to its rugged fanless computers. The Hailo-8™ processor is a compact edge AI accelerator that provides up to 26 tera operations per second (TOPS) and only uses a typical power consumption of less than 2.5 W. Edge AI deployments can integrate a low-power module with an industrial-grade Premio inference computer to process inference analysis and object detection workloads in real time. The processor is available in three NGFF M.2 modules: B-Key, E-Key, and M-Key for plug-and-play integration. The RCO-6000-CFL computer utilizes the M-Key module to enable maximum throughput with four lanes of PCIe Gen 3 performance. Integration for AI inference is seamless.
COMSOL, Burlington, MA, has released the latest version of its modeling and simulation software, COMSOL Multiphysics® version 6.1. This release brings major upgrades to the fluid flow and mechanical simulation products. The CFD Module now includes high-fidelity turbulent flow with detached eddy simulation (DES). This yields the accuracy of large eddy simulation (LES) with substantially less computational effort. A new and fast method for mechanical contact is included in the Structural Mechanics Module and the MEMS Module. It introduces new functionality for solids, shells, and membranes with full support for self-contacting surfaces. There is a new method for assigning materials to thin structures that makes it easier to analyze gaskets, adhesive layers, and claddings.
Guill Tool, West Warwick, RI, has released a new reciprocating head. The traditional tip and die assembly is replaced with a linear reciprocating assembly that changes the tube’s profile within a given length. This process is repeated throughout a single extrusion run without interruptions. Cutting capability, in association with the extrusion speed, cuts the finished product to length. Only one extrusion run is needed to produce a finished product, as opposed to multiple extrusion runs with tooling changes along with a manual assembly operation to connect different tubing shapes. The reciprocating head eliminates an assembly operation as well as in-process inventory.
A versatile, general-purpose lubricant that prevents rust and acts as a cleaning agent is available from Fluoramics, Winona, MN. Tufoil Lubit-8 is dielectric with a breakdown voltage of 28 kV. It has an Extreme Pressure Falex test result of 4500 lbf. The lubricant is available in a dropper tip dispenser, plus in quarts and gallons. The 16.5 mL (0.557 fl oz) dropper tip bottle provides easy application to small areas. The lubricant leaves no oily residue, is compatible with all oils and greases, and remains stable from –51 °C (–60 °F) to 260 °C (500 °F).
Stainless Steel for 3D Printing
3DEO, Los Angeles, CA, has launched 316L stainless steel in high volume for metal 3D printing. The material exceeds MIM standards. A fully austenitic, non-magnetic stainless steel, 316L (equivalent to UNS S31603) maintains excellent performance at room and moderately elevated temperatures, as well as excellent ductility and mechanical performance. The weldable material is corrosion resistant, which makes it ideal for medical applications that will experience harsh environments.
Surgical Mask Tester
ForTest, Modena, Italy, has launched an instrument to monitor the appropriate airflow rate in full compliance with the EN 14683 standard for surgical mask testing. T9731-EN 14683 includes two air flow meters: a mass-flow meter with the range of 0.0...20.0 n (l/min) in which a servo-driven valve is regulated by software and a differential gauge/differential pressure measurement, which is used to measure the differential pressure of air passing through a surgical mask in Pa/cm2). Both are fully automatic and can measure airflow rate up to 20,000 cc/min with the resolution starting from 0.1 cc/min.
SABIC, Houston, TX, has introduced two new polycarbonate (PC) copolymer resins designed to offer a robust chemical and impact resistance, thin-wall transparency, dimensional stability, and processability. In device applications such as clear covers, screens and display lenses, the new materials can overcome key drawbacks of incumbent PC resins and co-polyester resins when exposed to disinfectants or aggressive chemicals. The new resins include LNP ELCRES™ CRX1314TW copolymer and its biobased equivalent, LNP ELCRIN™ CRX1314BTW copolymer, which offers up to a 42 percent reduction in carbon footprint based on life cycle assessment (LCA). Both grades feature limited biocompatibility according to ISO 109931.
Covestro, Pittsburgh, PA, has launched an ultradurable material for healthcare and life sciences. Makrolon® 3638 polycarbonate offers durability from cryogenic to steam sterilization conditions with high impact strength and ductility. It has been tested for biocompatibility according to USP Class I, ISO 10993-5 and ISO 10993-10 and meets the requirements for skin contact applications. Ability to be sterilized using methods most prevalent in the healthcare industry. It is designed to be tough and durable to withstand everyday use while maintaining structural integrity.
