possible elimination of external IO requirements for laser control, as well as reduction or possible elimination of external PLC programming. Multiple process cycles may be created, stored and uploaded to allow fast switching between products. The user can program the following parameters: pulse shape to be used, shutter state, ramp up or ramp down, laser on time or number of shots to be fired and enable or disable external analogue power level control. For all process cycles each step may be configured to automatically progress to the next step or to wait for an external control system signal before moving on to the next step. In this way the manufacturing process may be coordinated with external motion systems.


The company will be promoting the use of lasers to weld, cut and drill medical devices, including surgical instruments and implants at the MEDTEC UK exhibition at the NEC in Birmingham on 6–7 April 2011.

Components for single-use systems


Qosina’s new components for single use systems include USP Class VI glass-reinforced nylon Biovalves that control the fluid flow rate and can reportedly be easily added to preassembled systems without cutting tubing lines.


The company’s patented barbed flanges with pre-attached gaskets work with glass-reinforced Bioclamps for easy assembly with a secure connection, and polypropylene BioEnd Caps plug the opening. Qosina also stocks a broad selection of related components including Colder Products Company’s quick disconnect couplings, C-Flex tubing, peroxide or platinum cured silicone tubing, giant pinch clamps and non-reopening ties.

Shannon Microcoil offers a range of medical shaft reinforcement coils. Its Integra range features an integrated marker band section in gold, platinum or palladium on one or both ends, which removes the need for expensive marker bands and associated process costs. The company claims unsurpassed anti-kink performance and superb radial crush resistance for these coils. They are supplied in sizes of 0.002 x 0.004 ins up to 0.016 x 0.028 ins in any length, with plating thicknesses up to 5 micron (20 micron through-the-line).

44 ¦ April 2011 www.med-techinnovation.com Compounds for device shielding


SABIC Innovative Plastics has introduced LNP Thermocomp high specific gravity (HSG) compounds for radiation shielding in response to coming regulatory changes to the lead replacement exemption for medical devices (Category 8 products). When the Restriction of Hazardous Substances (RoHS) Directive came into effect in 2006, medical devices were given a temporary exemption from lead restrictions. However, this exemption is expected to expire as early as 2012. In addition, China is intending to mirror the Directive in its own regulation and may echo enforcement measures adopted by the EU. The LNP Thermocomp HSG compounds utilise metallic fillers in a


PA resin matrix to create HSG compounds that effectively block radiation and avoid “hot spots” that can occur with lead shielding. Avoiding the secondary operations required with lead and gaining the freedom to consolidate multiple parts can also reduce total manufacturing time, and system cost and complexity. These benefits can compensate for the low cost of lead. For wireless devices, the company offers LNP Faradex compounds. These utilise electrically conductive stainless steel fibres in a resin matrix to provide excellent electromagnetic interference/radio frequency interference shielding. The advantages of these materials include design flexibility with available custom colour, avoidance of secondary operations, reduction in cycle times through efficient injection moulding and lower weight than cast metal.

Platen sealing station


Water Line has developed a new platen sealing station for its Ritemed CH pouch making machine, which is used for the production of chevron pouches and sterilisable rolls. The new design features an upper chiller platen to prevent heating to the control integrated on the top of the station, and a new fixing system for the platen


sealing die enables fast die change. A reverse die set platen with four locked trained posts, driven from the top with static base by one fully programmable independent digital servo drive, ensure the web path remains linear throughout the machine. The system is available in width sizes of 600 and 900 mm.
