Can Seamer
A can seamer is a machine used to seal the lid to the can body. The lid or "end" is usually tinplated steel (food) or aluminum (drinks) while the body can be of metal (such as cans for beverages and soups), paperboard (whisky cans) or plastic. The seam formed is generally leak proof, but this depends on the product being canned. The seam is made by mechanically overlapping the two layers to form a hook. Different parameters of the hook are measured and monitored to check the integrity of the seam under different conditions. The shape of the double seam is determined by the shape of the seamer roll profile and the relative position. During the can seaming process, the seamer chuck holds the can while the rolls rotate around it. Initially, the first operation roll folds the lid (end) and then the second operation rolls tightens the resulting seam. The first operation seam is critical to avoid problems like wrinkles (tightness issues) and leaks. The shape of the seam is determine ...

Fully Automatic Can Seaming Machine
Fully () is a municipality in the district of Martigny in the canton of Valais in Switzerland. History Fully is first mentioned in the 11th Century as ''Fuliacum''. Geography Fully has an area, , of . Of this area, 30.5% is used for agricultural purposes, while 27.7% is forested. Of the rest of the land, 5.7% is settled (buildings or roads) and 36.2% is unproductive land. It is on the right bank of the river Rhône and is well known for its wines. Fully is just the administrative name of a group of several villages of Vers-l'Eglise (sometimes called Fully), Branson, Châtaignier and Randonnaz along with a number of hamlets. The natural reserve of Les Follatères (shared between Fully and Dorénaz), located on the south facing slopes above the Rhône elbow, has a variety of animal and plant species normally uncommon in Switzerland.

Metal
A metal (from Greek μέταλλον ''métallon'', "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well. Metals are typically ductile (can be drawn into wires) and malleable (they can be hammered into thin sheets). These properties are the result of the ''metallic bond'' between the atoms or molecules of the metal. A metal may be a chemical element such as iron; an alloy such as stainless steel; or a molecular compound such as polymeric sulfur nitride. In physics, a metal is generally regarded as any substance capable of conducting electricity at a temperature of absolute zero. Many elements and compounds that are not normally classified as metals become metallic under high pressures. For example, the nonmetal iodine gradually becomes a metal at a pressure of between 40 and 170 thousand times atmospheric pressure. Equally, some materials regarded as metals c ...

Paperboard
Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker (usually over 0.30 mm, 0.012 in, or 12 points) than paper and has certain superior attributes such as foldability and rigidity. According to ISO standards, paperboard is a paper with a grammage above 250 g/m2, but there are exceptions. Paperboard can be single- or multi-ply. Paperboard can be easily cut and formed, is lightweight, and because it is strong, is used in packaging. Another end-use is high quality graphic printing, such as book and magazine covers or postcards. Paperboard is also used in fine arts for creating sculptures. Sometimes it is referred to as ''cardboard'', which is a generic, lay term used to refer to any heavy paper pulp–based board, however this usage is deprecated in the paper, printing and packaging industries as it does not adequately describe each product type. History In 1817, the first pape ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Whisky
Whisky or whiskey is a type of distilled alcoholic beverage made from fermented grain mash. Various grains (which may be malted) are used for different varieties, including barley, corn, rye, and wheat. Whisky is typically aged in wooden casks, which are typically made of charred white oak. Uncharred white oak casks previously used for the aging of sherry are also sometimes used. Whisky is a strictly regulated spirit worldwide with many classes and types. The typical unifying characteristics of the different classes and types are the fermentation of grains, distillation, and aging in wooden barrels. Etymology The word ''whisky'' (or ''whiskey'') is an anglicisation of the Classical Gaelic word (or ) meaning "water" (now written as in Modern Irish, and in Scottish Gaelic). This Gaelic word shares its ultimate origins with Germanic ''water'' and Slavic ''voda'' of the same meaning. Distilled alcohol was known in Latin as ("water of life"). This was translated into Ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1 ...

Double Seam
A double seam is a canning process for sealing a tin can by mechanically interlocking the can body and a can end (or lid). Originally, the can end was soldered or welded onto the can body after the can was filled. However, this introduced a variety of issues, such as foreign contaminants (including lead and other harmful heavy metals). The double seam was later developed as a cheaper and safer alternative and quickly replaced the welded seam. The double seam is made using a double seamer, which can have just one or a number of heads or seaming stations. The double seam is formed by mechanically interlocking five layers of material together: three layers of the can end and two layers of the can body. Each seaming head typically consists of two rolls, a first operation roll and second operation roll, and a chuck. Some seaming machines have two first operation rolls and two second operation rolls and a few machines use a method called "rail seaming" which requires no rolls. Durin ...

Industrial Processes
Industrial processes are procedures involving chemical, physical, electrical or mechanical steps to aid in the manufacturing of an item or items, usually carried out on a very large scale. Industrial processes are the key components of heavy industry. Chemical processes by main basic material Certain chemical process yield important basic materials for society, e.g., (cement, steel, aluminum, and fertilizer). However, these chemical reactions contribute to climate change by emitting carbon dioxide, a greenhouse gas, through chemical reactions, as well as through the combustion of fossil fuels to generate the high temperatures needed to reach the activation energies of the chemical reactions. Cement (the paste within concrete) * Calcination – Limestone, which is largely composed of fossilized calcium carbonate (CaCO3), breaks down at high temperatures into useable calcium oxide (CaO) and carbon dioxide gas (), which gets released as a by-product. This chemical reaction, call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
