A Verissimo Engineering manufactured Dye NGX Pressbrake has been recently installed by Sealegs the NZX listed developer and manufacturer of the self launching and self recovery amphibious boats.
The Australasian designed and made press brake was implemented on the Sealegs factory floor in order to help the marine manufacturer meet the additional demand as it diversifies its range into a new series of rescue vessels.
“When you are constructing marine rescue craft, there is absolute instance on realibility and readiness” emphasised Darren Leybourne of Sealegs.
“We knew that we had to have a large scale machine tool that was customised to our exact specifications. We knew also that we had to have instant support at all times for this new central machine tool”. In the event, the machine and its backup were not far away from the Sealegs plant at Albany Dye's NGX press brake range had the 325 tonne capacity and the 6m length needed by the boat builder.
The new press confers on Sealegs the ability to fold aluminum into hulls in one press sequence for its range of up to 7m long craft. The Dye Press brake incorporates the company’s own anti deflection system together with radius tooling, means that aluminum of any required size can be pressed to its precise shape without featuring unwanted contours or deflections.
Taper folding was also important here, and upon consultation with Dye it was agreed that the Dye X1 power probe on the back gauge was the right solution for Sealegs needs. Similarly the Press brake is equipped with a bottom beam table width specifically for Sealegs applications.
“We are export-led” notes Darren Leybourne and just because we supplying foreign markets, there must be attention to reliability, durability and precision, and this must remain constant regardless the volume of sales”. When the issue of the need for a big capacity press first arose, Sealegs looked closely at issuing a tender for an imported centerpiece machine tool.
“This was looked at in considerable depth,” notes Mr. Leybourne. “But every time we looked at an imported model the question arose ‘what if we need specialist support and the only people standing behind the product are sales specialists?’
It was then that Sealegs selected the Dye NGX Press brake. Engineers of both companies worked closely together to refine a number special purpose customisations needed for the amphibious craft builder…. The customisations, some of them slight and others more extensive, proved to be long term value in the pressing of each individual hull and its component parts of around 75 other aluminum elements , all routed in house by Sealegs.
This is intricate work and needs to be because a Sealegs boat can be driven from a storage location , down a boat ramp or beach and into the water- all with the occupants staying in the boat remaining completely dry. Once in the water, the Sealegs wheels are easily retracted into the “UP” position and are completely out of the water. The boat is driven and used as normal. When approaching land, and recovery the Sealegs wheels are lowered into the “DOWN” position whilst still moving through the water.
