Fundamental Basics About Los Angeles Metalizing Firms

By Kate McMahon


Los Angeles metalizing companies are very good for hire because they offer very cheap rates for quality services. Metalizing is defined as the process of coating non metal substrate with metal. This process has been in existence since 1835 when it was discovered by Justus Von Liebig. Justus discovered this phenomenon in the process of trying to coat a glass surface with metallic silver, in order to make a mirror.

Metalizing is done so as to get coatings that can withstand abrasion and corrosion and yet remain pretty. Various processes entailed include vacuum, galvanic, fire, contact, and diffusion metallization. Fire metallization process entails immersing substrates in liquefied metals. The key methods are copperizing, zinc coating, aluminizing, leading, and chromium, silver, gold, nickel, cadmium, and tin plating.

The system utilized to perform the coating is made of about six different parts. The first component is the power source, which is normally a standalone that powers the torch. A robot is used for manipulating the substrates to be metalized or the torch. Spray torch is also known as the spray gun. The gun is the main constituent that melts and propels the particles that have to be deposited onto the substrate.

The feeder is situated next to the gun. Its work is to supply the spray gun with the wire, powder, or liquid it needs to do the coating. The system is managed from control console, which might be made independently or may be an integral of the whole system. The medium, which also is the substance utilized in coating the object may be in gaseous, solid, or liquid form. The media generate the plasma jet and/or flame required.

Vacuum metallization involves placing the object to be metalized in a vacuum cabinet together with the metallic coating substance. The coating metal is heated till it evaporates. Upon evaporating, the metal condenses over the object as a thin film. The work piece is continuously rotated to ensure that the film is applied uniformly. This process can be done on any kind of material ranging from ceramic, paper, and plastic to 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 the coating is flawless and brilliant, the surface to be coated and the substrate must be clean with no contamination. Main sources of surface contamination are dust, oil, grease, fingerprints, mold, and dirt among several others. One piece of object should be coated at any given instance to avoid flaws.

Los Angeles metalizing businesses have all that is needed to make faultless coatings in hours. The equipment utilized by these corporations are high-tech and very advanced. Many items including electronics, buttons, wedding rings, utensils, furnishings, watches, cooking ware, and earrings among others get decorated using metallization process. Custom jobs can be done upon placement of personal orders.
