Pollution in the later stage of hardware parts processing should be followed up

With the aerospace, defense industry, and microelectronics, there is an increasing demand for precision/ultra-precision mechanical parts (feature sizes ranging from micrometers to millimeters). The specialization of the processing structure and shape of its hardware parts, the diversification of parts and materials, the high precision of size and surface quality have become the salient features of high-precision mechanical parts and their miniature devices and equipment. Requirements for reliability and other aspects are also getting higher and higher.
At present, the main processing of hardware parts exists in western developed countries and some developing countries and regions with high economic development levels. High-precision machinery manufacturing technology is known as one of the lO key technologies in the 20th century. It is the key development direction of the 21st century and is highly valued by countries all over the world. Many enterprises have also formulated regulations on electroplating pollutant discharge indicators, plating parts rinsing water quota, rinsing water quality standards and corresponding technical measures in accordance with their own conditions and development plans, and incorporated them into the enterprise’s production plan management, and established pollution control files. , Regular inspections and assessments to control environmental pollution caused by the “three wastes” of electroplating. Therefore, the national environmental situation has only improved in recent years.
