About electrical resistors (except heating resistors)
cpc code 4712 covers the production of electrical resistors, a critical component in a wide range of electronic devices and systems. Electrical resistors are passive electronic components that are used to control or limit the flow of electric current, playing a vital role in the functioning of various electronic circuits and devices. This industry is an essential part of the broader electronics and electrical equipment manufacturing sector, contributing to the development and advancement of technology across numerous industries.
Production process
The production of electrical resistors typically involves a multi-step process. The key steps include the selection and preparation of raw materials, such as carbon, metal alloys, or ceramic materials, which are then formed into the desired resistor shape and size. This is often done through processes like molding, extrusion, or deposition. The resistors are then subjected to various treatments, such as heat treatment or coating, to achieve the desired electrical properties and resistance values. Finally, the resistors are tested, assembled, and packaged for distribution.
Production inputs
The main inputs required for the production of electrical resistors (except heating resistors) include raw materials such as carbon, metal alloys, and ceramic materials. Additionally, specialized machinery and equipment, such as molding machines, deposition systems, and testing equipment, are essential for the manufacturing process. The industry also relies on skilled labor, including engineers, technicians, and production workers, to operate the equipment and ensure quality control.
Production outputs
The primary output of the electrical resistors (except heating resistors) industry is, of course, the resistors themselves. These components are then consumed by a wide range of industries, including 4711 Electronic components, 4713 Electrical equipment, and 4714 Electronic consumer goods, among others. Electrical resistors are integral to the functioning of various electronic devices, from consumer electronics to industrial equipment, making this industry a crucial part of the broader electronics and electrical equipment manufacturing sector.
