Die-casting machine It is an important metal processing equipment, widely used in automobile manufacturing, electronic products, aerospace and other industries. In the process of die casting, quality inspection and control are the key steps to ensure the stability and consistency of product quality. Liansheng Precision Die casting machine manufacturer This article will introduce how to carry out quality inspection and control of die-casting machine to ensure that the products produced reach high quality standards.
1. Raw material inspection: the first step of quality inspection is to inspect raw materials. Metal alloy or other materials used in die casting shall comply with relevant standards and specifications. The chemical composition and physical properties of raw materials are tested to ensure their quality stability and reliability.
2. Mold inspection: mold is an important factor affecting product size and surface quality. Before the start of the die-casting process, the mold should be strictly checked and tested to ensure that the dimensional accuracy and surface finish of the mold meet the requirements.
3. Parameter setting: Before the operation of the die-casting machine, the processing parameters should be set reasonably according to the product requirements and process characteristics. Including the setting of injection speed, injection pressure, injection speed, injection temperature and other parameters. Reasonable parameter setting can ensure the dimensional stability and good surface quality of products.
4. Machine monitoring: During the die-casting process, the die-casting machine should be monitored, including the recording of pressure, temperature, speed and other data. Through monitoring data, abnormal conditions can be found in time, and machine parameters can be adjusted to maintain the stability and consistency of the die-casting process.
5. On site inspection: on-site inspection of die casting products is an important part of quality control. Check the size, surface quality, holes and pores of the product to ensure that the product meets the design requirements and customer needs.
6. Non destructive testing: In order to find the defects inside the product, non-destructive testing methods can be used, such as X-ray testing, ultrasonic testing, etc. These methods can help find the quality problems hidden in the product, and repair and adjust them as soon as possible.
7. Product sampling inspection: regularly conduct sampling inspection on products, and randomly select samples from production batches for laboratory testing. Through testing the mechanical properties, chemical composition, hardness and other aspects of the sample, we can understand the overall quality of the product.
8. Continuous improvement: quality control is a continuous process. Through summarizing and analyzing the problems in the production process, find out the root causes of the problems, take measures to improve, and constantly improve the product quality.
In conclusion, the quality inspection and control of die-casting machine is the key step to ensure the stability and consistency of product quality. Through strict detection and control of raw materials, molds, machine parameters and the whole process of products, it can ensure that products reach high quality standards, meet customer needs, and improve the competitiveness of enterprises. At the same time, continuous improvement and continuous optimization of the production process are also the key to maintain product quality and lay a solid foundation for the sustainable development of the enterprise. Die casting machine manufacturing enterprises should attach great importance to quality control, strengthen staff training, improve technical level, constantly innovate, and constantly improve product quality and production efficiency.
