The starting point of all high-quality products lies in the selection and mixing of raw materials. The raw materials of magnetic material advertising consumables mainly include iron oxide powder, adhesives and other functional additives. The selection of these raw materials is directly related to the magnetism and durability of the final product.
In the raw material mixing stage, the key is to ensure the uniform distribution of all raw materials. This requires precise metering and efficient mixing equipment. The mixing ratio, mixing time and mixing speed of the raw materials need to be strictly controlled to ensure that each batch of raw materials is mixed evenly, laying a solid foundation for subsequent steps.
After the raw materials are mixed, they need to go through the calendering process. Calendering is the process of rolling the evenly mixed raw materials into thin sheets under high pressure. The key to this step is to control the pressure and speed of calendering, as well as the water content of the raw materials.
Appropriate pressure and speed can ensure that the raw materials are evenly rolled into thin sheets, while avoiding structural damage caused by excessive rolling. The water content of the raw materials also needs to be strictly controlled, because too much or too little water will affect the calendering effect and the performance of the final product. Through precise control of process parameters, the calendering process can shape green sheets with ideal structures, laying a good foundation for the subsequent sintering process.
Sintering is the most critical step in the manufacturing process of magnetic material advertising consumables. In this step, the calendered green sheets need to be sintered at high temperatures to obtain ideal magnetic properties and structural strength.
The sintering process needs to be carried out within a specific temperature range, and the sintering time and temperature curve need to be precisely controlled. Too high or too low temperature, too long or too short sintering time will have a serious impact on the performance of the final product. Therefore, the sintering process requires the use of advanced sintering equipment and precise temperature control systems to ensure that each step is carried out under strict process parameters.
During the sintering process, the oxide powder in the raw material will undergo a chemical reaction to form a ferrite structure with magnetic properties. Binders and other additives will also undergo physical and chemical changes at high temperatures, further enhancing the structural strength and stability of the product. Through precise sintering processes, magnetic material advertising consumables with ideal magnetic properties and structural strength can be obtained.
Although the sintered magnetic material has basic magnetism and structural strength, it still needs further processing to enhance its durability. Edge compounding is the key to this step.
Edge compounding is the process of compounding the sintered magnetic material with edge protection materials (such as plastic, rubber, etc.). This step can protect the edge of the magnetic material from physical damage and enhance the overall durability of the product. In the edge compounding process, the type, thickness and composite process parameters of the composite material need to be strictly controlled to ensure the best composite effect.
The magnetic material after edge compounding finally needs to go through the processing and forming steps to meet the needs of different application scenarios. Processing and forming includes cutting, punching, bending and other processes, which are aimed at processing magnetic materials into products with specific shapes and sizes.
In the processing and forming process, process parameters such as cutting speed, punching force, bending angle, etc. need to be strictly controlled to ensure the accuracy and stability of the final product. It is also necessary to properly handle the waste in the processing process to meet environmental protection requirements.
In the manufacturing process of magnetic material advertising consumables, quality control is a key link throughout. From the selection of raw materials to the setting of process parameters at each step, strict testing and monitoring are required.
The quality inspection of raw materials includes component analysis, particle size distribution, water content and other aspects to ensure that the quality of raw materials meets production requirements. During the process, intermediate inspection of the output of each step is required to promptly discover and correct possible problems. The final product also needs to undergo comprehensive quality inspections, including magnetic testing, weather resistance testing, corrosion resistance testing, etc., to ensure that its performance meets customer requirements and industry standards.
With the continuous development of the advertising industry and the changing needs of customers, the manufacturing process of magnetic material advertising consumables also needs to be continuously innovated and improved. By introducing advanced production equipment and process technology, as well as carrying out continuous R&D activities, the performance and quality of products can be continuously improved to meet the needs of the market and customers.
For example, by improving the sintering process, the magnetic and structural strength of magnetic materials can be further improved; by introducing new edge-wrapped composite materials, the durability and environmental protection of products can be enhanced; by optimizing the processing and molding process, the precision and stability of products can be improved. These technological innovations and continuous improvements provide a strong guarantee for the high quality of magnetic material advertising consumables.
