ADVERTORIAL MATERIALS IN DESIGN & PROTOTYPING DP Seals gets it right for Milkrite Fast cure G


potting silicone ood gap filling and sealing capacity,


high durability and resistance to humidity and UV


radiation are the qualities that the LOCTITE® Si 5611 alkoxy silicone brings to electronic component assembly. Typical applications are in the production of solar and lighting systems, illuminated signage, switches and electronic connectors. This two-part, low viscosity silicone is designed for both bonding and sealing. The basic resin is a white liquid and the hardener is black, creating a grey liquid when combined. A LOCTITE® cartridge press gun with mixing nozzle ensures the efficiency of this process; standard and customised automatic dispensing equipment is also available. As LOCTITE® Si 5611 is also self levelling it is particularly useful as a potting silicone to protect electronic components, increasing the quality and span of their service life. Service temperature is up


to 200C. This addition to the LOCTITE® silicone range has been formulated for applications that require a fast cure at room temperature.


example, a full strength bond on aluminium can be typically achieved in 12 minutes on a 0.13mm gap.

P Seals, the Poole-based manufacturer of rubber seals and mouldings, has now entered full production of the seals it recently developed for Milkrite’s latest automated milking system.

Milkrite has established a reputation for innovation in milking technology and the new Impulse Claw 300 has been designed to offer optimum levels of efficiency, ease of operation and cow comfort.


DP seals developed three different seals for the unit, utilising its wide- ranging knowledge of materials, proven engineering skills and specialist manufacturing expertise to deliver components that fully met the stringent specifications.


The Impulse Claw 300 is Milkrite’s latest ground breaking product As well as the large outer ring that seals the two halves of the claw, the company also worked on


the gasket seals and O-rings that are vital to the integrity of the unit – with all three being produced in a compound that would safely come into contact with both the milk being collected and any cleaning agent that might be used in normal operation. In addition, the seals and material had to be FDA compliant, in order for Milkrite to market the new product in the USA and worldwide.


“This product provides a vivid illustration of the enormously wide range of applications in which our seals are used,” said DP Seals MD, Andrew Piper, “and we hope to be supplying more high quality components for the next generation of products that Milkrite develops.”

Award-winning airline trolley set to revolutionise the industry I


ndustry leaders believe a model of a lightweight aircraft trolley could boost in-flight security and save airlines thousands of pounds per year.


Prototyping company Ogle, based in Letchworth,


was asked to create an accurate model of a trolley with the aim of making the equipment more secure and more cost-effective.


Wrexham-based company Flightweight Limited, which specialises in lightweight trolleys and security solutions for the aviation industry, had identified that standard airline trollies suffered from a number of design flaws.


Flightweight’s pioneering trolley, which won the best onboard catering equipment prize at the Onboard Hospitality Awards earlier this year,


is


fitted with an electronic, multi-point lock and security seal, replacing the cable ties which airline staff currently use. The company has also been awarded the Made in Wales Green Award for their innovative flax-based FibriRock, a pioneering new material that is aerospace approved and 98 per cent recyclable.


The radical lock system, created by Elelock Systems Limited,


an associate company of


Flightweight, is able to record the opening and closing of the trolley, which will prevent theft, while also making it easier to track the sale of duty free products.


The trolley is 30 per cent lighter than standard


trollies, which could make a fuel saving of up to £400 per year, per trolley, providing airlines with a vital carbon offset.

Chrys Chrysostomou, director of design and manufacturing at Flightweight said:


“Having


worked with Ogle over many years they were a natural choice. We are extremely impressed with the Ogle model and are very excited about what it could mean for airlines in the future.”


Flightweight’s groundbreaking design is also easier to repair than current trollies, which have to be sent away for repair in a lengthy and costly process. The flat pack, modular design means each individual panel can be taken out and replaced easily.


Ogle marketing and sales director Dave Bennion


said: “We are very proud to have worked with Flightweight to create this model, their inspiration and outstanding design will undoubtedly deliver significant savings for airlines. We also believe this trolley will be kinder on the environment and help make life easier for cabin crew.”


The project was completed in just two


weeks, with extensive use of CNC machining, and rapid prototyping (SLS) to cut production time to a minimum.


The main body of the trolley was CNC machined from lightweight composite FibriRock.


Using


production spec parts meant the finished prototype was as close to the final, full production item as possible in terms of weight and durability.
