Summary: The metallization of plastic has completely revolutionized the costs associated with manufacturing.
Plastic is a great material to use for manufacturing, but its uses are limited when it is left in its original state. But, what if we could metalize it and change its properties entirely? That’s no longer in the realm of “what if.” Through the process of vacuum metallization, manufacturers are able to fundamentally alter the makeup of plastic, turning a simple plastic piece into a high-performance metal piece without adding significantly to the cost of production.
How it Works
The vacuum metalizing process takes place in two phases. The first phase involves superheating the materials used in coating. Typically, these materials include items like copper or aluminum. The heating would damage the substrate, so the piece is inserted only after the metal has been converted into gaseous form. The chamber is cooled as the substrate is put inside, creating the perfect conditions for materials to settle on the face of the substrate and coat t evenly. The particulates bounce off the walls of the chamber as the interior is cooled to a specific temperature. Occasionally, other apparatuses are used to rotate the substrate, making sure it receives an even coating on all sides.
Applications
Vacuum deposition systems aren’t just for making plastic into metal, although the aerospace industry benefits greatly from these advancements. The same process is also used in the construction of joint replacement devices, creating a more durable piece that lasts longer. Optometrists and manufacturers also utilize this same technique, replacing the metal with chemicals, to create lenses with scratch resistance.
