Information About Los Angeles Metalizing Process
Non-metallic objects sometimes need to have metallic properties to make them useful in certain applications. The process by which metallic properties are induced into non-metals is referred to as metallization. In Los Angeles metalizing is done by many companies and specialists who have enough experience in the field. Some of them have accomplished government and other major contracts through the many years they have been in service. Comparing the level of quality in the services they render, their charges are very reasonable.
Mirrors are among the earliest items to get metalized. Therefore, the process is almost as old as mirrors. Justus Liebig, the inventor of this process made the discovery in 1835. He was trying to coat glass with a layer of metallic silver when discovered the process. The application of the process became more popular when ABS plastics were introduced into the market.
Non metallic objects have very poor heat and electrical conductivity. As a result, their ability to be plated is reduced making it necessary to turn them into conductors first before plating is done. Chemical etching is the commonest method used to turn non-metals into metals. A mixture of sulfuric and chromic acid is the primary chemical employed in this case. Maximum etching is attained by dipping the object into the hot mixture for a specified period.
Before the actual plating is done, the object is first sensitized and then activated through various means. Using electroless copper or nickel to coat the activated surface enhances the resultant bond between the substrate and the coating. The bond is normally strong although it is weaker when compared to that formed between metal-to-metal plating.
Metalizing activity is carried out inside an appliance called a vacuum chamber. The object and coating are carefully positioned in the equipment before starting the process. The temperature of the chamber is then raised to the boiling temperature of coating metal. Electron beams, resistance heating, and plasma heating are some of the heating methods used to raise the temperatures. On reaching the boiling point, the metal vaporizes to form fumes.
The vaporized metallic fumes settle down onto the substrate to form a uniform coat over its surface. The resultant coating is normally very uniform and smooth. The thickness of the coating can be adjusted through the controls on the vacuum chamber. Leaving the substrate inside the chamber for a long period of time also allows the coating to grow thicker. The temperatures of non-metallic objects must however be maintained at reasonable levels at all times to prevent them from melting or getting disfigured.
The applications of metallization in industrial, domestic, and commercial settings are very many. Major applications include reduction and/or prevention of erosion, wear, and corrosion in machinery. In structural materials, it provides protection against extreme temperatures and electrical contacts. This process can also change the aesthetic and electrical properties of objects. Plating substrates using shiny metals such as gold and silver boosts the aesthetic value of the plated object.
Various factors affect the price of the equipment used for metalizing. Some of the factors include capacity, quality, functions, and model. Some are small devices while others are the size of a room. Normally there are replacements for worn out parts.
