Conductive Compounds Reduce Static Noise

Connectors Unlimited has worked with RTP Company to formulate and supply plastic materials for a shielding solution for analogue cable and circuit connectors. Several static dissipative and conductive compounds were chosen for the improved static control they provided. 'The fundamental reason for using RTP Company's conductive plastics in our analogue connectors is to minimise noise interference in the electronic signal, which is primarily caused by static charge,' explained Marty Ignasiak, president of Connectors Unlimited. 'By effectively reducing static charges, we're able to improve the signal-to-noise ratio in our connectors and thus upgrade overall performance of devices,' he added. When selecting a supplier of conductive plastic compounds, Connectors Unlimited engineers kept three critical requirements in mind: thermal conductivity, electrical conductivity and structural rigidity. Maintaining dimensional stability of the analogue circuits during manufac

NSK Bearings Save Costs For Carbon-Fibre Producer

NSK 's SpaceA range of bearings has solved a problem of premature failures of stainless-steel bearings used in the manufacture of carbon graphite and composite materials for aerospace applications. Operating in a solution of ammonium bicarbonate, the stainless-steel bearings were failing after about six weeks; however, the SpaceA replacements have been operating for eight-months without problems, providing significant savings for the manufacturer. The SpaceA bearings are situated at both ends of five rollers, over which the carbon-fibre material passes in a surface-treatment process before being submersed in the bath of ammonium bicarbonate. This is an arduous application for bearings, as illustrated by the fact that the 10 stainless-steel 6205 bearings that were used previously were failing and requiring replacement every six weeks. In addition, analysts calculated that the frequent replacement was costing far too much in lost production time. Keen to remove these costs and impr

Barden Provides Super-Precision Bearings

The Barden Corporation offers custom-designed, super-precision bearings for use in a wide variety of high-performance air handling systems. Certain technologies demand custom-engineered, high-precision bearings rather than standard catalogue bearings. Air handling or air movement systems, for example, often require high-precision bearings, especially if the application is critical or requires a bearing solution that offers long life, high reliability and high speeds. Other factors that make high-precision custom bearings essential to many applications are high temperatures, high pressures, poor lubrication, low vibration levels or abnormal contamination levels. Air handling systems are commonly found in every industry sector. Examples include axial and radial flow fans, compressors, turbomolecular pumps, dry pumps, emergency magnetic touchdown systems, turbochargers, air conditioning systems and cooling systems used on military aircraft for engine, avionics or infrared weapon systems

Internal Diameter Gripper Holds Irregular Parts

SAS Automation has introduced an Internal Diameter Gripper (IDG) for parts that are heavy, fragile or have an irregular shape. The IDG grips and releases on command and is recommended for manipulating breakable and heavy parts.

Fanuc Robot Handles Special Brick Variants

Wienerberger UK has engineered an automated system for handling special brick variants in partnership with Fanuc Robotics UK. The system uses a Fanuc Robotics M710-iC six axes robot to pick up green bricks from an input conveyor and positions them onto a ceramic pallet where they remain until fired. Bricks are handled separately with a 'suits-all' vacuum gripper solution, a vision system and bespoke palletising software. Single or double bricks enter the system on a conveyor and their precise position is identified by a vision system using Fanuc Robotics IR-Vision integrated software. The M710-iC robot is fitted with a single vacuum gripper that orientates itself to information fed by the vision system and picks up the brick. The control panel has PC and Human Machine Interfaces (HMI) that allow the shape to be drawn, edited and dimensions to be input. From this information the software defines where the gripper locates the brick, where to place the brick and how to orientat

Smart-Trak mass-flow controller utilised by MBARI

The Monterey Bay Research Institute (MBARI) is using Sierra Instruments' mass-flow controllers to discover how increasing atmospheric CO2 levels are affecting marine life in seas. The Monterey Bay and our oceans are changing rapidly due to the influx of CO2 in the atmosphere. According to Dr Barry, a benthic biologist and senior scientist at the Monterey Bay Research Institute, about one-third of human CO2 gas emissions in our atmosphere are absorbed by the ocean, making the ocean 30 per cent more acidic than 100 years ago. 'Ocean acidification' is the term that has been coined to describe this process. Early in his experiments, Barry was frustrated with the performance of the mass-flow controllers that controlled gas inputs to his aquarium tanks. After research and discussions with Sierra Instruments, he chose the company's Smart-Trak model 100 with its Pilot Module gas feature. Barry and his team installed nine Smart-Trak Model 100 units to control mixtures of O2,

CGTech Releases Enhanced CNC Simulation Software

CGTech has released version 7.0 of the Vericut CNC machine simulation and optimisation software. Vericut 7.0 features enhancements that reduce the time required for manufacturing engineers to develop, analyse, inspect and document the CNC programming and machining process. CGTech have focused on code optimisation and customer-driven enhancements, reducing the number of pop-up dialogues for day-to-day Vericut users and eliminating any confusion associated with 'apply', 'ok' and 'cancel' buttons. As a result, setting up a new project in Vericut has been simplified.  Items formerly in pop-up dialogues have been moved to the Project Tree, where all projects are configured using a configuration panel, automatically displayed as the user selects each branch. Actions are immediate, so 'apply' or 'okay' clicks are unnecessary. The Component Tree has also been merged into the Project Tree but can be optionally hidden. The Project menu has been simplifie

Tentec Refurbishes Bolt-Tensioning Tool

Tentec has helped the Artemis Ocean Racing team after its bolt-tensioning tool seized just six days before a big race. The tensioning tool failed while refitting the vessel's keel and the technicians needed help fast. After a quick call to Tentec, an engineer was sent to Ocean Racing's HQ within the hour to assess the situation. As suspected, it was the tool cell within the tensioning equipment that had been damaged and required refurbishing back at Tentec's factory. The bolt tensioner had been specifically designed and manufactured by Tentec. The application uses titanium bolts to hold the long central stabiliser 'fin' of the yacht and needed a special insert within the tool. This fin is fully adjustable via hydraulic rams for various trim settings of the vessel. The bolts are held within a glass-fibre structure at the base of the mast, which is the critical stress area of the vessel. However, time was of the essence and the demands of the refit meant the team c

PEM Spotfast Provides Permanent Flush Mounting

The latest PEM Spotfast fastener from Penn Engineering permanently joins metal sheets to PC boards or plastic panels and creates a flush-attachment connection without protrusions on either side. These fasteners offer alternatives to riveting or adhesives and their rotational capability extends application potential with the fastener serving as a single flush-mounted pivot point. The steel fasteners (Type SFK) install smooth with the top metal sheet and flush or sub-flush with the bottom panel. When used as a pivot point, the top metal sheet is captivated between the head of the fastener and the lower (non-rotating) panel, which allows the metal sheet to rotate freely. The fastener's design features two separate clinch and knurl joining profiles that hold the key. Squeezing the fastener into place using punch and anvil causes a cold flow of the metal sheet material into the fastener's clinch profile and a broaching fit of the knurled end into the PC board or plastic panel. Th

Softnoze Introduces Machine Vision Mounts
