In the field of silicone product production, regular silicone lid is a common product, and its yield rate is directly related to the production cost and market competitiveness of enterprises. Improving the yield rate requires careful optimization from all aspects of the production process.
Strict screening of raw materials is the basis for improving the yield rate. The quality of silicone raw materials varies, and there are obvious differences in impurity content, hardness, and vulcanization characteristics. Before production, a complete raw material testing system should be established, and each batch of silicone raw materials should be fully tested by professional equipment, including component analysis, physical property testing, etc. Ensure that high-purity and stable silicone raw materials are selected to reduce defective products caused by raw material problems from the source, such as surface defects caused by impurities and molding defects caused by unstable performance.
The accuracy of mold design and manufacturing has a significant impact on the yield rate. When designing the mold, the fluidity, shrinkage and other characteristics of silicone should be fully considered. Use advanced computer-aided design (CAD) and computer-aided engineering (CAE) technology to simulate the flow filling process of silicone in the mold, optimize the gate position, quantity and size of the mold, and avoid problems such as insufficient filling and trapped air. In the manufacturing process, high-precision processing equipment and advanced technology are used to ensure low surface roughness and high dimensional accuracy of the mold, and reduce the undesirable phenomena such as regular silicone lid size mismatch and excessive flash caused by mold wear or dimensional deviation.
Accurate adjustment of molding process parameters is a key step. Vulcanization temperature, time and pressure are the core parameters affecting the molding quality of regular silicone lid. Too high temperature may cause silicone to burn, yellowing, hardening and other problems; too low temperature will result in insufficient vulcanization and insufficient product strength and elasticity. Through experiments and data analysis, the optimal process parameter table for regular silicone lids of different specifications is established, and the automatic control system is used for precise control during the production process to ensure that each regular silicone lid can be molded under ideal conditions and improve product quality stability.
Strict control of the production environment cannot be ignored. Silicone is extremely sensitive to dust, moisture, etc. When produced in an open or unclean environment, impurities are easily mixed into the silicone, affecting the appearance and performance of the product. A clean production workshop should be established, equipped with air purification equipment, and the temperature, humidity and number of dust particles in the workshop should be strictly controlled. At the same time, standardize the dress and operation procedures of operators, reduce pollutants introduced by human factors, and reduce the probability of product defects.
Quality inspection in the production process should be carried out throughout. Set up multiple inspection processes, from raw material entry inspection, mold first piece inspection, to random inspection during production and full inspection of finished products. Use a variety of inspection methods, such as visual inspection of appearance, dimensional measurement, physical property testing, etc. Timely discover and eliminate defective products, and at the same time, through the analysis of defective products, feedback to the production process, and continuously improve process parameters and operating methods.
Employee training and skill improvement are also important guarantees for improving the yield rate. Regularly organize employees to participate in professional training, covering silicone material knowledge, production process principles, equipment operation skills, and quality control points. Improve employees' understanding of the production process and operational proficiency, so that they can be sensitive to abnormal situations during the production process, and take correct measures in time to reduce product defects caused by human errors.
Optimizing the regular silicone lid production process to improve the yield rate requires concerted efforts and continuous improvements in multiple aspects, including raw materials, molds, molding processes, production environment, quality inspection, and employee skills, in order to achieve a dual improvement in product quality and production efficiency.
