The raw materials of PEVA rubber and plastic card code are mainly composed of PEVA resin, plasticizer, stabilizer, pigment and other auxiliary materials. These raw materials need to be strictly screened and proportioned to ensure the quality and performance of the final product. As the main substrate, PEVA resin has excellent flexibility, weather resistance and environmental protection, and is an ideal choice for the production of card code.
The prepared raw materials are sent to the mixer for mixing. The purpose of mixing is to mix various raw materials evenly and plasticize them to prepare for subsequent molding. During the mixing process, the mixing temperature and time need to be controlled to avoid overheating or decomposition of the raw materials.
The mixed and plasticized raw materials are sent to the molding machine and molded through the mold. The design of the mold needs to be customized according to the shape and size of the card code. During the molding process, the molding temperature and pressure need to be controlled to ensure the dimensional accuracy and appearance quality of the card code. After molding, it is also necessary to perform shaping treatment to further consolidate the shape and size of the card code.
The molded card code needs to be sent to the cooling equipment for cooling. The purpose of cooling is to quickly cool down and solidify the card code to improve its hardness and strength. During the cooling process, the cooling speed and temperature need to be controlled to avoid deformation or cracks in the card code.
After cooling and solidification, the card code needs to be cut and trimmed. Cutting is to remove the card code from the mold and cut or split it as needed. Trimming is to remove burrs, flash and other defects on the surface of the card code to improve its appearance quality and performance.
After cutting and trimming, the card code needs to be quality inspected. The inspection content includes dimensional accuracy, appearance quality, physical properties and other aspects. Only products that meet quality standards can be allowed to leave the factory. After passing the inspection, the card code needs to be packaged to prevent damage during transportation and storage.
Throughout the production process, quality control is the key to ensuring product quality. Through strict raw material inspection, process control and finished product inspection, problems in production can be discovered and solved in a timely manner. In addition, continuous improvement of production processes is required to improve production efficiency and product quality. This includes optimizing raw material ratios, improving molding processes, and improving equipment accuracy.
The production process of PEVA rubber and plastic card code involves multiple links such as raw material preparation, mixing and plasticizing, molding and shaping, cooling and curing, cutting and trimming, inspection and packaging, quality control and continuous improvement. Each link needs to be strictly controlled and managed to ensure the quality and performance of the final product.
