Inert gases, or noble gases, are the gaseous elements in the helium group of the periodic table which are considered chemically nonreactive. These gases, which do not form chemical compounds, are helium, neon, argon, krypton, xenon and radon. Inert gas welding is a welding process which uses

Food quality control is an important measure that must be taken to prevent contamination and misuse of food supplies by manufacturers, suppliers and distributors to protect the health of consumers. Maintaining a high standard in food quality control is dependent on methods that range from th

Green industry is a term that can be used for industrial businesses that use environmentally-friendly practices, or those that produce eco-conscious products. In the 21st century, increased awareness and education about global warming, climate change, and the impending exhaustion of natural

Materials requirements planning (MRP) and lean manufacturing are two different methods of production. MRP often relies heavily upon procuring dependent demand supplies to maintain inventory. Lean, on the other hand, strives to eliminate inventory and produce in a just-in-time manner. These c

Sitting on a chair may not engender any grand ideas about history, but the truth is that every single piece of furniture in the office, house, or even at the park is part of an industry that has spanned centuries and provided work for millions. The furniture industry is a vast collaboration,

Cogging is a method of metalworking used to change the grain of a piece of metal. It is a hot forging technique involving two anvils with shaped surfaces. This kind of shaped anvil is called a die. The term cogging may come from the fact that the metal is meant to be pressed into the shape o

A melting furnace is an appliance capable of heating materials to such a high temperature that they melt, which from a chemical perspective basically means that they reach the critical threshold temperature at which they convert from a solid to a liquid. Not all materials will melt, and thos

Planishing is a technique used to curve and shape thin pieces of sheet metal. The process involves tapping the metal with a specialized planishing hammer while it rests on a rounded stake in order to smooth defects and achieve the proper curve. Planishing is commonly performed in auto body s

Wet grinding is a milling process used to produce powder or paste from a solid using a liquid such as water. It can also be used in an abrasive process to reform hard objects. There are numerous items that can be processed in this way, including grains and ores. Such techniques are used for

A hollow edge blade is a knife blade with a series of evenly spaced vertical indentations close to the cutting edge. These indentations confer several advantages to this type of blade, making the blade very popular in busy kitchens. Many knives designed for sushi, such as santoku knives, are

Sometimes called the most important technological advance of the 20th century, the Haber-Bosch process allows the economical mass synthesis of ammonia (NH3) from nitrogen and hydrogen. It was developed a little before World War I by Fritz Haber and Carl Bosch, who were German chemists. Haber

Factory seconds refer to products that did not meet a final quality inspection standard by the manufacturer. Everything from clothing to furniture to flooring can be marked as factory seconds, and often sold at factory outlets or other discount stores for a significantly lower prices. This i

Operational maintenance is a type of preventative maintenance used to extend the life of equipment and maximize performance. It includes many types of minor adjustments, cleaning, and inspections, depending on the machine. While major repairs are typically handled by trained technicians, ope

Industrial fermentation is the same process household bakers use when applying yeast to bread, but on a much larger scale. This procedure ferments certain materials into useful products by using microorganisms, carbon, nitrogen, oxygen and an energy source to power the fermentation. This is

The electric smelting furnace is a device used to melt iron, ores and other materials into a liquid material that can be poured into molds or added to other various materials to create certain alloys. Using electricity to create the required heat to melt the materials, the electric smelting

The glass manufacturing process can be traced back to 3500 BC, when ceramic pottery was coated with a glass surface glaze. While there are many modern variations on the glass manufacturing process for industrial and scientific uses, traditional glass used to make windows, food and drink cont

Job production is the provision of a set of unique services or products for a particular client or customer. It is also called jobbing; the person, company or group of persons engaged in it is called a jobber. An example is when the repair of certain machinery in a company is entrusted to on

Tape casting is a materials process companies use to create dense, flexible ceramic types for use in manufacturing products like capacitors. This technique requires special equipment as well as advanced chemistry skills to make the composition of the tape suitable for the need. Companies may

Heliarc® welding is a form of welding introduced and perfected in the 1940s. The reason the welding process is referred to by this name is because the welding process requires the presence of two substances. These substances are helium, an inert gas that is used for the shielding of the weld

Die sinking is a process used to machine or create a specific size or shape cavity or opening in steel blocks. The openings in the steel blocks can then be used to mold plastic into different shapes. Such openings may also be used when doing forging, either hot or cold, or for coining or die
