It is undeniable that cladding and plating are both processes which coining utilizes to create multi-layer micro-stampings or custom sheet metal stamping composed of two or more metal alloys such as the Copper Silver Alloy. The outer layers can be the appropriate alloys to facilitate joining these parts to mating surfaces.
You should know that cladding is a multi-step process where two or more metals are joined or bonded together in strip form under high pressure without adhesives or filler materials. In order to assure a quality bond, the individual metal strip layers must be thoroughly cleaned and then brushed to provide a contaminant-free bonding surface. The metal strips such as silver copper-clad metal strips are then bonded together in a highly controlled rolling operation, often with inline brushing.
Once the metals are bonded tightly, they can be rolled as one strip just like silver-clad strips, annealed. And then it often repeats that operation again. Rolling clad materials can increases the hardness of these metals with the help of normal strip processing while annealing is able to remove residual stresses and softens the materials like cold-forming titanium so that they can be further rolled as necessary.
The challenge with any clad manufacturing is to create the proper combination of initial strip thickness, cleaning or brushing steps, rolling operations, and annealing processes so as to bring cost savings effectively. In order to make the desired clad material with the specified individual layer thicknesses, manufacturers like Silver Clad Strip manufacturers need to pay more attention to this process.
Once the clad material reaches the desired thickness and composition, the metal is cross-sectioned to testify proper individual layer thicknesses, and then the strip is slit to the desired width and coiled to the proper length. Therefore, the exact volume of solder or braze layers can be tightly controlled via cladding, assuring that the correct volume of joining material can be located in the exact area where it is needed.
Thanks to a contributed team of operators and equipment, it focuses on manufacturing clad strips which the company processes into multi-layer micro stampings. It can particularly specialize in cladding whose base materials are molybdenum, Alloy 42, copper, silver, and so on. In addition, the company procures need special clad materials from outside suppliers. To our surprise, it has successfully combined knowledge of rolling, brushing, annealing, stamping, and cleaning, which can greatly help to ensure that the multi-layer micro stampings or a&i metal stamping can completely meet customers’ needs.
Coining uses highly selected outer suppliers like Silver Clad Strip suppliers to plate its stamped parts such as stamped aluminum parts. The company specializes in supplying stamped and plated and molybdenum tabs, bonding pads, covers, terminals, heat sinks, and cover assemblies. Shapes as small as 0.010 inch (0.25 mm) in one dimension can normally be plated.
In most cases, components such as stamped components are first plated with one metal. And then, it will be plated again with a second metal such as nickel plating followed by gold plating. This double plating of parts is repeated at the customer's request such as nickel plating and gold plating from time to time.
