Publish Time: 2025-02-12
As an important part of new energy vehicles, the quality of stamping parts of new energy electronic control cover is directly related to the safety and reliability of vehicles. Therefore, it is particularly important to conduct strict quality inspection and control of stamping parts of new energy electronic control cover.
Quality inspection is the key link to ensure the quality of stamping parts of new energy electronic control cover. This mainly includes appearance inspection, size inspection, material inspection and internal defect inspection. Appearance inspection mainly checks whether there are defects such as cracks, wrinkles, bruises, burrs, etc. on the surface of stamping parts. It is usually observed by naked eyes or low-power microscopes, and high-precision instruments such as laser scanning and optical imaging can also be used. Size inspection focuses on the key dimensions of stamping parts, such as length, width, height, etc., to ensure that they meet the design requirements. Commonly used measuring equipment includes three-coordinate measuring machines, laser scanners, etc. Material inspection aims to verify whether the material composition and mechanical properties of stamping parts meet the requirements. Commonly used methods include chemical analysis, tensile test, impact test, etc. Internal defect detection uses ultrasonic, ray, eddy current and other technical means to detect whether there are defects such as cracks and pores inside stamping parts.
In terms of quality control, a series of measures have been taken to ensure the quality of new energy electronic control cover stamping parts. First, the raw materials are strictly controlled to ensure that the chemical composition, mechanical properties, surface quality, etc. of the raw materials meet the requirements. Secondly, the molds are regularly maintained and serviced to ensure their accuracy, stability and life, so as to produce high-quality stamping parts. In addition, the stamping process is strictly controlled, including parameters such as stamping speed, pressure, temperature, etc., to ensure the stability and efficiency of the stamping process.
In the production process of new energy electronic control cover stamping parts, quality control measures such as online partition inspection, first piece, middle piece, and tail piece extraction inspection are also implemented to reduce the number of defective parts, supervise and confirm the implementation of online partition inspection, and facilitate defective traceability. At the same time, the whole basket inspection and secondary selection inspection are carried out on the parts to further ensure the quality of the stamping parts.
In summary, the quality inspection and control of new energy electronic control cover stamping parts is a systematic project, involving the inspection of appearance, size, material and internal defects, as well as the quality control of raw materials, molds, processes, etc. Through strict quality inspection and control measures, the quality of new energy electronic control cover stamping parts can be ensured, providing strong guarantee for the safety and reliability of new energy vehicles.
