Vacuum / Ion Plating:
White Metal is any alloy that is light-colored, and is used especially as a base for plated silverware, ornaments and jewelry. Some of the metals used to create this alloy are antimony, tin, lead, cadmium, bismuth and zinc. Not all of these metals are found in all white metal alloys, but are combined to achieve a desired need, such as being able to be casted and polished.
Vacuum/Ion Plating is more durable and wear-resistant than traditional plating methods. Additionally, its great advantage is environmental consciousness as it avoids chemical solution during the process and it’s irritation-free for the skin. Vacuum/Ion Plating is an advanced technique normally in the watch, electronic and space industries. The object is placed in a vacuum chamber, which is pumped down to the desired vacuum pressure. The chamber is then heated to the target temperature to evaporate the material, which is sprayed onto the object, producing a thin layer of coating.
