When I think of coating services my mind wanders back to repainting the walls of a bedroom in my grandma’s house before I moved in to stay with her for a while. Thankfully, I had a lot of help in transforming the room, from cleaning the walls to applying the primer to finishing the final coat. However, coating services refer to much more then getting your friends and family in on your painting projects, or hiring the local small business. Industrial coatings are a varied spectrum of protective and enhancing materials that coat a vast range of substrates, or the surfaces to which they are applied. For example, my bedroom walls would be considered the substrate in my story. The two main reasons to utilize coatings are to protect the substrate from environmental conditions, corrosion and wear, and to give the substrate any desired characteristics that the coating may have and the substrate lacks. The purpose of my painting job was to totally change the look of the room. Besides aesthetics, desirable characteristics of a coating include magnetic, electrical and anti-reflection properties, resistance to water, UV waves and chemicals, and added strength and durability.
Besides marking the end of summer and the start of a new school year, the close of August also brings the Primetime Emmy Awards, a show highlighting and honoring popular actors, actresses and television shows. The trophy that is awarded to each winner of a winged muse holding an atom is one of the most recognizable of its kind. The Academy Awards feature another icon: a trophy called Oscar. These two trophies have more in common than what meets the eye because they are both a result of the manufacturing process die casting.
In many contexts the word steel has become synonymous with strength and durability, qualities illustrated by its use in such arduous industries as automotive, aerospace, construction, electronics and even shipbuilding. While it seems clear from these many uses, many are unaware of the incredible diversity of the material. Rather than one specific iron alloy, the steel family includes hundreds of permutations of the element, each precision designed for optimal performance in variable conditions. On top of this, finishing treatments and processing are commonly used to bolster the capabilities and capacities of steel products such as steel plates, strip and tubing. As much as 30% of all industrial steel products and 45% of specialty steel undergo some type of pre-processing before moving into full scale production. Most of this work is performed by the highly skilled professionals of steel service centers across the nation.
In 1966, James Brown began a ballad with the assertion that ‘this is a man’s world.’ The song goes on telling that men built the cars, trains and other essential elements of modern infrastructure. While this was true at the beginning of the industrial revolution in the late 18th Century, by Brown’s time women played an important role in the industrial workforce. Though much later than the initial movement, the women’s industrial revolution came about at the beginning of WWII. Up until this point the positions suited to the fragile female form were domestic or clerical. With men leaving for war, however, this changed drastically as is demonstrated by one of the most iconic figures of the time: Rosie the Riveter. Depicted as a strong, but womanly sheet metal worker this figure inspired many women of the time to fill industrial vacancies and help to build countless planes, bombshells and other metal components needed in the war effort. Despite demands that they return to domestic roles at the end of the war, the presence of women in the industrial sector has risen steadily ever since. While men may still make up a larger percentage of the workforce in the field of sheet metal fabrication, an increasing number of modern women follow in the footprints of Rosie.
Look at the two images below. How do you think those round metal disks are transformed into that perfect, beautiful trophy? Maybe some form of molding or welding, definitely with the use of heat. If that’s your guess…you’re wrong! It’s formed by metal spinning, a process that doesn’t use heat at all and looks just like forming pottery on a wheel, only with metal. It was once considered a true art form that took skill, practice and talent. It might surprise you, but metal spinning has been around since the ancient Egyptians, to form objects like bells, bowls, light fixtures and event trash can lids. Hockey fans should appreciate this process, since the Stanley Cup itself was originally a large goblet made by metal spinning.
Many of the strongest metal products available today like knives, swords, train parts, die casting molds and musical instruments are made of extremely resistant, durable and tough materials. Although metals like steel and iron are the best metals for the job, sometimes they need a little help to obtain the desired hardness and strength properties for the tough jobs that the automotive, weapons, transportation and military industries have in mind. In order to make these metals even stronger than they already are, the products and parts are altered physically, mechanically and even chemically to obtain certain properties.
by PSI Extrusions The aluminum extrusion process, which involves forcing hot aluminum through a precision die to create a length of constant cross-section, marries the inherent advantages of aluminum to the precision and high volume capacity of the extrusion process.
