Metal manufacturing encompasses a wide range of methods that are used to alter the condition of metallic materials. Metal processing is most often performed for two main purposes: to shape the metal, such as in metal spinning and metal stamping, or to alter the state of the metal’s surface, such as in galvanization or coating. Of these two purposes, metal forming is more common, and it includes processes like metal injection molding, metal casting, metal extrusion and more. In addition, there are many processes that are more unique and specialized. For instance, there are material specific processes like aluminum extrusion or processes that specifically form sheet metal. Although there is a wide variety of metal manufacturing processes, some of the most common methods of metal processing for industrial applications include electroless nickel plating, metal etching, roll forming, water jet cutting, die casting, forging and metal stamping.
Aluminum anodizing is a surface hardening process in which electrolytic passivation is used to thicken the layer of oxide that naturally occurs on aluminum alloys. Used to increase corrosion and wear resistance, anodizing can be performed on a variety of metals, such as titanium anodizing; however, amongst anodizers, aluminum is typically the metal of choice since it is naturally prone to corrosion due to alloying elements such as copper and iron.
Coating services refer to various processes that are used to apply a thin layer of material onto another material, which is often referred to as the substrate. There are many different purposes that coatings can serve, but the primary two reasons to coat a substrate are to protect the substrate from environmental conditions, corrosion and wear-and-tear. Coating can also give any desired aesthetic characteristics such as color, tint, scent and texture to the substrate that it does not already possess.
EDM, an abbreviation of electrical discharge machining, is a specialized tooling method that uses electrical energy to cut, drill, etch and machine metal parts. Electrical discharge machining is one of the most accurate types of machining processes as it is able to achieve complex geometries and details especially when using CNC EDM machines to control the process. EDM cutting and drilling is also suitable to be used for both hard materials and extremely delicate materials which are difficult to machine with conventional cutting methods.
Electroless nickel (EN) plating is an auto-catalytic chemical reaction that results in a layer of nickel alloy, typically nickel-phosphorus or nickel-boron, to be deposited onto a solid substrate like a metal or plastic workpiece. A reducing agent, such as hydrated sodium hypophosphite, is crucial to the electroless nickel plating process because it reacts with the metal ions and allows for the nickel to be deposited.
Electromagnetic interference, commonly known as EMI is a kind of electromagnetic radiation that can damage, lessen or interrupt the functions of electronic devices and equipment. EMI can travel along conductors, electrical circuits and wires. Similarly, radio frequency interference (RFI), which is radiated electromagnetic “noise,” travels through the air as radio waves, where it causes the same problems as EMI. Generally appearing in the form of an enclosure, transmitted signal or coating, EMI shielding engages in a process that was developed to protect vulnerable electronics from the influence of EMI and RFI.
EMI shielding stops EMI and RFI from entering or exiting a certain region by creating a barrier from magnetic or conductive materials. As though it were under a dome, a shielded device is isolated from everything outside. External fields cannot infiltrate the device, and internal fields cannot escape to affect other sensitive equipment. Any industry that uses modern communication devices depends on EMI shielding products
Heat treating is any of several methods for altering the atomic structure of a metal or other crystalline structure in order to instill beneficial physical, chemical and mechanical properties, such as strength or ductility. These production and manufacturing techniques utilize systematic heating and chilling to modify the behavioral properties of industrial materials.
