Another resemblance that foldforming has is the paper fold technique known as "origami". The process of folding and unfolding a flat material is seen in both metal foldforming and papering folding origami. Many of the principles and issues that come with the folding and unfolding process can be seen in origami and foldforming. [7]
With each technique, the process begins with the making of the granules themselves. [2] The granules are made from the same material as the base to which they will be affixed. Very narrow fringes may be cut along the edge of a thin sheet of metal, a further cut producing small squares or rectangles of metal.
The Fourcault process is a method of manufacturing plate glass. First developed in Belgium by Émile Fourcault (1862–1919) during the early 1900s, the process was used globally. Fourcault is an example of a "vertical draw" process, in that the glass is drawn against gravity in an upward direction. [1] Gravity forces influence parts of the ...
In addition, mould materials include aluminium alloys, glasslike or vitreous carbon, silicon carbide, silicon nitride and a mixture of silicon carbide and carbon. [18] A commonly used material in mould making is tungsten carbide. The mould inserts are produced by means of powder metallurgy, i.e. a sintering process followed by post-machining ...
Batch processing is one of the initial steps of the glass-making process. The batch house simply houses the raw materials in large silos (fed by truck or railcar), and holds anywhere from 1–5 days of material. Some batch systems include material processing such as raw material screening/sieve, drying, or pre-heating (i.e. cullet). Whether ...
Porous glass is glass that includes pores, usually in the nanometre- or micrometre-range, commonly prepared by one of the following processes: through metastable phase separation in borosilicate glasses (such as in their system SiO 2-B 2 O 3-Na 2 O), followed by liquid extraction of one of the formed phases; [1] [2] through the sol-gel process; or simply by sintering glass powder.
Cenosphere formed from coal combustion, magnified 400×. A cenosphere or kenosphere is a lightweight, inert, hollow sphere made largely of silica and alumina [1] and filled with air or inert gas, typically produced as a coal combustion byproduct at thermal power plants.
A stage in the manufacture of a Bristol blue glass ship's decanter.The blowpipe is being held in the glassblower's left hand. The glass is glowing yellow. As a novel glass forming technique created in the middle of the 1st century BC, glassblowing exploited a working property of glass that was previously unknown to glassworkers; inflation, which is the expansion of a molten blob of glass by ...
