Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.

Recently, the Ministry of Environmental Protection issued an announcement on its official website that since January 1, 2013, all gas-fueled ignition engines and vehicles produced, imported, sold, and registered must comply with the requirements of the National Five Standards, and related companies should promptly Adjust production, import and sales plans.
According to the announcement, enterprises producing or importing gas-fueled ignited engines and automobiles should submit an application for approval to the Ministry of Environmental Protection in accordance with the requirements of the State Five Standard, and submit environmental protection production conformity assurance plans, annual reports, and vehicle identification codes (VIN) information. . The Ministry of Environmental Protection issues environmental protection type approval certificates for the vehicles that have passed the audit. Automobile production companies must establish and improve the environmental protection production conformity assurance system, and effectively strengthen the production process of environmental compliance management, quality control of key components of environmental protection, vehicle emission self-inspection, and so on, to ensure that the actual production and sales of vehicles meet the national five standards.
The Ministry of Environmental Protection stated that it will continue to intensify inspections and adopt regular inspections and spot checks to comprehensively strengthen the environmental protection supervision of motor vehicle manufacturers. For those who do not meet the standards, they will be ordered to make rectification within a time limit; if they still fail after the rectification, the model for environmental protection type approval of the vehicle shall be revoked and notified.
In addition, local environmental protection agencies at all levels must strictly comply with the discharge standards in the routine inspection of motor vehicle exhaust emissions and the issuance of environmental protection certification marks. For vehicles that do not meet the standards, environmental protection agencies at all levels shall not issue environmental protection inspection marks and cooperate with the public security department to stop its registration in its administrative area.
The Ministry of Environmental Protection shall, in accordance with law, impose penalties on the production, import, and sales of vehicles that exceed the standards.
