Vacum forming
The most suitable method for batch production of my product is VACUUM FORMING. This is because all of the necessary facilities are readily available. It is used to manufacture a variety of products in thermoplastic materials. These products range in size from garden pond liners to food trays used in supermarkets. The first thing which is done in the process is the mould being attached to a support plate. The platen and mould are then lowered and rigid thermoplastic sheet material is clamped onto an air tight gasket and usually heated from above. Once the thermoplastic sheet is softened enough, then air is blown in to raise the sheet in a slight bubble before the platen is raised bringing the mould into contact with the plastic. Any trapped air remaining between the platen and the heated plastic sheet is then evacuated by a vacuum pump. Atmospheric pressure acting over the top surface completes the forming process by pressing the plastic sheet onto the mould. Once the plastic sheet is cooled down to below it's freeze point the air flow is reversed to lift the forming off the mould. Moulds can be made from a variety of materials such as wood, medium density fibreboard (MDF), plaster of paris and clay. MDF will be used as a mould for the casing of my product. This is because of how it is quick and easy to shape compared to solid wood due to having no grain and is
Ghost Story
Does Sir Douglas Haig deserve to be included in a list of "Butchers and Bunglers" of the First World War? Field Marshal Douglas Haig was born on the 19th June 1861. He was a British soldier and senior commander during World War I. He commanded the British Expeditionary Force from 1915 to the end of the War. Most notably he was commander during the Battle of the Somme, the 3rd Battle of Ypres and the series of victories leading to the German surrender in 1918. Haig was the son of John Haig, who was head of the family's successful "Haig & Haig" whisky distillery. Haig studied at Brasenose College, Oxford. He left without a degree, partially due to sickness. He graduated the following year in 1884 as an officer. Was Sir Douglas a Butcher or a Bungler of the First World War? Historians have varying views with many reasons to support either theory. There are many reasons saying that he should be included in a list of Butchers because he sent thousands of men to their deaths at the battle of the Somme believing that there was every chance of success, and there are many reasons saying that he should be included in a list of bunglers because he believed that he was right about things even though his most trusted men told him otherwise, he misunderstood the battlefield, mainly because he was never at the battlefield. Instead he was 40 miles behind the front line living in a chateau.
