Try using Reflow moulded into membrane flow mesh as an alternative to one time use flow media. Cut the cost of your consumables, improve set up and clean up times by reducing processes and speed up infusion times.

Reflow is a patented texturized sheet to allow membrane building encapsulating 0.5 x 0.5 grooves at 1cm grid spacing. This provides inbuilt resin flow “mesh” which is reusable and not consumable. Peel ply may or may not be used in conjunction with this product. Reflow is available in convenient A4 size sheets and ordered in 1 m2 packs (16 sheets).  The thin sheets are simply fitted to the mould calibration with spray mount and coated with a wax release agent prior to membrane manufacture.

I was privileged to visit SMT in Forst, Germany recently and witnessed the highly professional streamlined infusion moulding techniques the company has developed using our reusable vacuum membranes
Germany’s ICE fleet trains use SMT’s new lightweight infused flooring to replace previously installed heavy wooden panels. The fire resistant, structural composite sandwich replacement flooring bring excellent weight savings allowing new air-conditioning, seating and entertainment system additions.

SMT is the exclusive suppliers to Deutsche Bahn AG producing 25,000 m2 for the 66 train fleet comprising 8 carriages each. The company gained an enormous advantage with the system for its simplicity and closed mould characteristics ideal for worker ease and safety. Workers are able to gain great efficiency in moulding by the basic infusion process and clean extraction after infusion. Very little waste resin is evident and the cost and waste management savings over unsound traditional consumable bagging are significant gains for the company.

SMT not only have worked closely with their supplier to assure quality and structural integrity of the new sandwich floor panelling but also have their own teams of installers taking delivery from production to fit out on each carriage refurbishment.

Wright Composites in Ballymena, Co Antrim, Northern Ireland recently held an open day within WrightBus’s main works for school children and school leavers John Elder, operations manager asked for the loan of our demo moulding kit for the”Face”. Apparently, this went down well with attendees and as the mould was heated a good demo to the boys in the moulding shop of how effective heated composite moulds can be.

Last year we posted how a composite moulding company were delighted with our reusable vacuum membranes. Today, Mark Silvester, CEO of Dartford wrote to me. I copy his email for you.
"Hi Alan
We are still making train seats. Up to about 4,250 so far with another 1,000 to go. The great thing I have found from a business perspective is that it is now a job performed by a factory operator as opposed to a far more expensive laminator. We have replaced a few of the skins during this time but have found by having a spare ready to drop in if needed then production isn’t affected if repairs are needed. Waste is minimal and rejects are very low. The staff like the system, one of the biggest sceptics moulds the end-caps you originally demonstrated the system on. This now runs with two base moulds and the single skin moving between moulds nearly doubling production and the laminator loves the job. A win-win for me, happy staff and an 80% increase in production.""
Mark goes on to say...
"If you have any prospective customers that wish to ask me about the system please do not hesitate to give them my details."
We say who needs an advertising budget when clients write such glowing approval of our system? Thank you Mark

Last week we were delighted to share our technology with so many enthusiastic composite Nort American moulders. Coming mainly from Canada we also had visitors from USA and one from Japan at our 34 attendees Masterclass. Hosted by FormaShape in Kelowna, BC 4 different mould designs were converted to closed mould reusable vacuum membrane technology. Unlike some who just demonstrate a system, our Masterclass actually taught all the techniques and supplied a valuable 52 page illustrated technology manual. Visitors were, therefore, able to leave with a full working knowledge and to immediately put into operation what they had learnt back at their moulding facilities. SAfter completion each mould was gel coated and glass loaded to clearly show the rapid fill and cure to completion of the ~VPI moulding process. All the very latest features including Morph resin runners, Reflow, and moulded 110% vacuum secure where clearly applied and production used for all to see the benefits of these unique innovations

Our masterclass workshop in support of Alan Harper Composites North America was a resounding success. The 34 delegates representing composites moulding companies from Canada and the USA were eager to learn in all aspects of reusable vacuum membrane manufacture and the benefits of the cost saving technology. In fact, the interest was so great the attendees were queuing up to purchase the equipment we used for the class as they were so enthusiastic to start using the system.
