1) WHAT IS ANODIZING AND ELECTROPLATING?
Anodizing is a coating of aluminum oxide that is grown from the aluminum by passing an electrical current through an acid electrolyte bath in which the aluminum is immersed. The coating thickness and surface characteristics are tightly controlled to meet end product specifications. Aluminum oxide is an extremely hard material that approaches the hardness of a diamond. As a result, the aluminum oxide layer provides excellent wear and corrosion protection. Hard anodize is more expensive due to increased energy requirements associated with the process. Ending cost differences are dependent upon many variables in a given order. For example: part size, racking instructions, packaging, etc.
Electroplating is a process by which metal in ionic form migrate from a positive to a negative electrode. An electrical current passing through the solution causes objects at the cathode to be coated by the metal in solution. The size, shape, and weight of the objects being plated determine how they will be plated. Electroplating is done to protect, beautify, insulate or increase the corrosion resistance, conductivity, or solderability of metal objects. It demands as much skill as any modern endeavor. Platers immerse objects into a variety of chemical baths in order to change their surface condition. Regardless of the finish being applied, the parts must be "surgically" clean.
2) WHAT IS THE DIFFERENCE BETWEEN AN ELECTROLYTIC & AN ELECTROLESS BATH?
Unlike conventional electrolytic nickel, no electrical current is required for deposition of Electroless Nickel. The electroless bath provides a deposit that follows all contours of the substrate exactly, without building up at the edges and corners. A sharp edge receives the same thickness of deposit as does an internal diameter.
3) WHAT SIZE PARTS CAN YOU HANDLE?
