Spotlight – quality counts
Glynn Garlick looks at how improvements and innovations help to provide first-rate products and solutions.
Accuracy is all important to industry, so manufacturers continually improve and upgrade their products to the highest quality.
US company MKS Instruments has introduced the Granville-Phillips Series 500 Cold Cathode Gauge, which sets a new accuracy standard (±10%) for wide pressure range CC gauges used to monitor vacuum performance. Applications include R&D, coating, semiconductor, analytical, high-energy physics, general vacuum and others requiring long life and accuracy. It offers a measurement range of 10-10–10-2 Torr and includes digital and analogue interfaces. The USB interface and GP connect software provides set-up and diagnostics, including screens for the gauge, graphing the pressure trend and checking usage statistics.
UK-based Holroyd Precision makes gear, rotor, screw and thread grinding and milling machines. Its Zenith 400 helical profile grinder is the Rochdale company’s first machine to offer all three grinding technologies – aluminium oxide, ultra hard plated cubic boron nitride (CBN) and vitrified dressable CBN. It can grind components up to 2.2m in length, and offers a 420mm maximum diameter grinding capability and a maximum component weight of 700kg. It also provides high stock removal rates.
Leak-Master Mapmax is used to check the integrity of packaging lines. Germany-based Witt-Gasetechnik’s latest version enables the detection of leaks using CO2 as a trace gas. A vacuum in the test chamber creates pressure differences between the packaging and the chamber, allowing ultra-fast sensors to detect leaks. Improvements include an optional dynamic area compression within the chamber for checking small volume packages with low gas content, such as sliced products, and a welded stainless steel frame that provides significant vibration stability.
Hi-line, UK, makes energy-efficient compressed air purification equipment. Its range of heatless pressure swing adsorption desiccant dryers, which remove water vapour, is now equipped with its new HDC-1 digital controller, providing a digital dew point display. The Burton-on-Trent company’s range of products has been extended to cover airflow capacities of 230–17,000 Nm3/h, as well as accommodating operating pressures up to 40 bar, with standard units rated at 11 bar. All models are fitted with safety relief valves. The dryer products are skid mounted, incorporating both pre- and post-filtration, and all associated pipework is made from stainless steel.
Surface Generation, a UK-based provider of advanced materials processing technologies used by aerospace and automotive companies, has adapted its production to functional specifications (PtFS) processes to improve the quality of injection moulding manufacturing. These use active thermal management technologies to allow temperatures to be controlled to the exact requirements of each mould area and process stage. PtFS can now be used to heat and cool injection moulds in real-time, allowing manufacturers to decide how long materials remain molten in the mould and control material flow to fill thinner complex moulds accurately using up to 75% less pressure.
It is innovations such as these that ensure companies can provide quality products their customers can rely on.
