  Coil coating line   is an automated and efficient method of coating metals. It is a continuous process that requires a roll of metal for each finishing step from cleaning to curing before packaging for shipping. Coil coating provides a consistently high quality product that is durable, corrosion resistant, cost effective, recyclable and more environmentally friendly than other alternatives. In this article, we will learn about the coil coating process, the different coating technologies used for coil coating.   Main steps The coil coating process starts with a coil of untreated sheet metal that is unrolled, treated, coated, cured, rewound and packaged for shipping at a rate of 100-200 meters per minute. This process can be used on one or both sides of the sheet metal and up to three layers of paint can be applied and cured. Sheet metal is most commonly aluminum, steel or galvanized steel, with varying coil sizes. The coil coating process is shown below. Stitching the st...

  Converting from in-house painted metal to outsourced pre-painted metal can save manufacturers money and time, and can ensure products of the highest quality. The most important issues to consider when converting to a pre-painted operation are time, capital expense, manufacturing costs and environmental compliance. The following are 10 indicators that manufacturers should consider using   coated steel or aluminum.   1. In-house paint shop costs are on the rise. When maintenance budgets are growing and capital investments are needed to comply with strict EPA regulations, pre-painted metal and aluminum are often cost effective alternatives to in-house paint lines. Many hidden costs are associated with in-house painting or powder operations. Staffing with trained personnel, equipment, supplies and even environmental compliance can add to the cost of owning an in-house paint shop.   TZ1600-30  Single-coating Aluminium   Coating Line   2.

  Coil coating is the way in which the coating material is applied to a strip of steel or aluminum. A coil of sheet metal is fed continuously into the process, which is controlled by accumulators at each end of the line. They load the bare metal coils at one end and release the finished product at the other end. In between, a coil coating process is used. What we are doing actually means high speed, continuous coil coating. What makes high speed, continuous coil coating possible is the uninterrupted application of cleaning, handling, coating, curing and potential leveling, while the sheet is flat, all in one high speed path through the coil  coating line.   Advantages Coil coating is replacing traditional manufacturing methods with value-added processes. The old practice of painting unpainted cars is being replaced by penetrating metal sheets. They are used for Nip coating or Dip coating with minimal solvent usage, helping to reduce VOC's. Coil coating is applied to flat ...

  Pre-painted metals are produced by continuously adding paint or film coatings to strip metals, primarily steel and aluminum. This process is called coil coating. The process involves cleaning and chemical pretreatment of the metal surface and one or both sides as necessary, single or multiple applications of (liquid) paint or coating powder, followed by curing or lamination with plastic film. The coated surface can have a wide range of colors, gloss levels and surface textures. It is the end use of the finished product that determines the coating choice. The user may require non-stick properties, high flexibility or high chemical resistance. Modern developments offer many new coating types to meet the growing needs of users.  Manufacturer LITONG  gives you an overview of developments in metal coating technology and paint technology. Painting metal industry There are several options for applying paint to metal. In the field, it is common to spray or brush; in the factory...

  You've probably heard some horror stories about your soda of choice. But could the seemingly insignificant and greatly overlooked soda be worse for you than the drink inside? A lot happens to soda cans under their aluminum surfaces. They are lined with a protective cover that prevents the soda inside from reacting with the metal.    Carbonated Carbonated beverages are often corrosive, not only to our teeth but to metal as well. This is because, in addition to carbonated water and lots of sugar, sodas also contain acid. Acids react with and corrode all kinds of metals, including the aluminum used in soda cans. If a typical soda is packed in an aluminum can without a protective cover, it can end up eating the material. This is because of phosphoric acid and citric acid. Soda can manufacturers, such as Ball, have determined that these substances have high corrosion levels and must be compensated for. To prevent any accidents, a protective coating is added to the inside of ...

  There are many questions in the powder coating vs. paint debate. How durable are powder coatings? Is powder coating better than paint? The answer can be boiled down to which of the two processes best meets the following criteria in   coating lines. 1. Cost-effectiveness of paints and powder coatings When considering economic factors, the main benefit of the powder coating process is its efficiency. With a typical transfer efficiency of 60-70%, approximately two-thirds of the powder used for a given application will achieve its intended purpose. In contrast, coatings have a transfer efficiency of only 30-35%, thus wasting two-thirds of the coating used for a given application. Even if you take the remaining volume into account, the powder application does not lose everything. Once the powder coating is complete, the percentage of powder that falls to one side can be collected and reused in the next cycle. Spray painting is not possible with this form of protection, and if it ...
