Electric Cartridge Heaters on the Crest of a Wave

Recreational sailing is a fantastic way of exploring the coastlines and seas of the world and there are of course a wide variety of vessels from which this can be achieved; be it a large yacht for extended excursions equipped with numerous on-board facilities and conveniences, to small dinghies or skiffs more suited to ‘daysailers’.

Sailing is a pastime suitable to all ages and budgets (dinghies can often be purchased for under £1,000) and the only real requirement for sailors is that of the ability to swim and of course a love for the sea and being on the water! However, regardless of the cost of the boat, it is important to ensure it is looked after and well maintained to help ensure its long life and sail ability.

One of the essential bits of equipment a boat owner should purchase to help care for their vessel is that of the fender. Fenders help to protect boats in a similar way to how bumpers protect cars in that they stop the boat from bumping into other vessels whilst mooring up. Although, historically, fenders were made from woven sections of rope, today’s fenders are generally fabricated in plastic, using the manufacturing process of extrusion blow moulding.

The process of blow moulding begins with the melting of a selected polymer to a molten state, using top-notch electric cartridge heaters, where it is then forced through a die to create a parison. The parison will then be inserted into a fender shaped mould, sealed at the base and then inflated to required size using warm air pressure. Once cooled, the fender will be released from the mould, ready for finishing and purchase by sea faring folk worldwide.
