Finest Cartridge Heaters and Your Garden

If a man’s home is his castle, then surely his garden is his Eden. Whether your outdoor space be a pot-filled balcony overlooking a sprawling cityscape, a rooftop terrace hidden away from the hustle and bustle of the daily grind, a patch of green bordered on every side by your neighbours’ green havens, or a rambling plot filled with swathes of apple trees and wildlife ponds, it is likely that most people will have given hours, days, months, years of their thoughts and time planning their space to create their ideal garden idyll.

But once the hardware is installed – the patio, the decking, the pond, the raised flower beds and maybe even a brick built barbecue for the hopeful, attention will then need to turn to the fauna and flora that will need to be planted in, so that your dream can come to life and be fully realised.

It is of course an expensive business, not only in the cost of purchasing the plants but also in the time spent tending to them. Every gardener knows that the ongoing care and maintenance of their garden is the crucial bit to keeping it looking lovely month after month. And so, as the summer months loom and the rich earth becomes ever more parched, the constant gardener will turn to their watering can for extra support.

Watering cans have been in existence since the 17th century, when they were made from metal. Today, although watering cans are still manufactured using metal, they are popularly purchased in plastic form.

The manufacture of the plastic watering can is undertaken using the process of extrusion blow moulding. Plastic raw material is fed into a hopper together with colouring agents and other additives such as UV protective chemicals, where it is forced by an electrically powered screw through a barrel and heated using (amongst others) cartridge heaters to melt the polymer to a molten state. The molten polymer is then forced through a die to produce a hollow parison. The parison is then inserted into a further mould where air is blown into the parison to inflate it to the shape of the mould. Once cooled, the new watering can is released from the mould ready for finishing and distribution to needy gardeners countrywide.
