Fundamentals About Los Angeles Metalizing Companies

By Kate McMahon


Los Angeles metalizing firms are very elegant for hire because they provide very cheap costs for high quality services. Metalizing is the process of covering non-metal substrates with metal. This procedure has been in use since 1830s when it was invented by Justus Von Liebig. Liebig discovered this phenomenon when trying to cover glass surface with silver, in order to produce a mirror.

Metalizing is performed to achieve coatings that are resistant to corrosion and abrasion and yet very decorative. Various processes involved include contact, vacuum, diffusion, galvanic, and fire metallization. Fire metallization involves immersing a substrate into a metal in liquid form. The major techniques are aluminizing, leading, copperizing, zinc coating, and nickel, chromium, tin, silver, gold, and cadmium plating.

The systems utilized to carry out the coating are made of about 6 different constituents. The first constituent is the source of power, which powers the torch and is normally a standalone. Robots are used for manipulating substrates for metalizing or the torch. Spray torches are also known as spray guns. The guns are the main constituents that melt and propel the particles that need to get deposited onto the substrates.

The feeder is located next to the spray gun. Its function is to supply the gun with the liquid, wire, or powder it needs to coat a surface. The system is operated from a control console, which may be made individually or may be integral. The media, which is also the substance used in coating the substrate may be in liquid, gaseous, or solid form. The media also generates the plasma jet or flame required.

Vacuum metallization involves putting the item to be metalized inside a vacuum chamber together with the metallic coating material. The coating substance is heated until it evaporates. After evaporating, the coating metal condenses over the item as a thin layer. The work piece is rotated continuously to ensure that the layer is applied evenly. This process may be done on any type of material including ceramic, plastic, paper, and glass.

The power supplies give the voltage needed to vaporize metals utilized for coating. Voltage generated is delivered to the electrodes, which connect a chain of standoffs that support tungsten filaments. The process takes around 2 to 3 hours for it to be complete. The structures and features of the produced film depend on aspects like cleanliness of vacuum chambers, methods of base preparation, and types of coating metal utilized.

Making sure that coatings are flawless and brilliant, the surfaces to be covered and the substrates must be clean without contamination. Key sources of contamination include dust, grease, fingerprints, mold, dirt, and oil among others. One work piece should be processed in a single cycle to avoid flaws.

Los Angeles metalizing firms have all it takes to produce flawless coatings within a few hours. The machines used by these companies are very advanced and of state of the art. Many items including earrings, wedding rings, utensils, electronics, buttons, cooking ware, furnishings, and watches among others are decorated using the process of metallization.
