Magnetic Sheets

What is the effect of sintering process on the performance of flexible magnetic sheets? How can manufacturers of flexible magnetic sheets control sintering temperature and time to ensure product quality?

Sintering, as one of the key steps in material preparation, has a vital impact on the physical properties, magnetic properties and even service life of flexible magnetic sheets. Flexible magnetic sheets are usually composed of three layers: a printed layer, an adhesive layer and a flexible rubber-plastic plate with magnetic molecules. The performance of the magnetic layer directly determines the adsorption capacity and stability of the material, and the sintering process is the key to optimizing the performance of this layer.

• Density and porosity: Appropriate sintering temperature and time can promote the formation of good bonding between magnetic particles, thereby increasing the density of the material and reducing the porosity. High density means stronger magnetic permeability and better magnetic retention, which is crucial for the adsorption stability of flexible magnetic sheets. However, too high a sintering temperature may cause the material to be over-densified, which in turn reduces its flexibility and affects the use effect.

• Magnetic properties: During the sintering process, the arrangement and orientation of magnetic particles are affected by temperature and time. Reasonable sintering conditions help to form an ordered magnetic structure and enhance the saturation magnetization of the material, thereby improving its adsorption efficiency and stability. On the contrary, inappropriate sintering parameters may lead to disordered arrangement of magnetic particles and reduce magnetic properties.

• Mechanical properties: The flexibility and wear resistance of flexible magnetic sheets are performance indicators that cannot be ignored in practical applications. The sintering process affects the mechanical properties of the material by adjusting the microstructure of the material. Appropriate sintering conditions can ensure that the material has good flexibility and weather resistance while maintaining sufficient magnetism, thereby extending its service life.

• Thermal stability: Sintering can also improve the thermal stability of the material, so that it can still maintain good magnetic properties and physical properties at higher temperatures, which is particularly important for outdoor advertising applications.

As an industry leader, HANKER has achieved extremely high precision in the control of the sintering process during the production of flexible magnetic sheets, thanks to its advanced production equipment, professional R&D team and strict quality control system.

• Advanced production equipment: HANKER has two modern production bases equipped with dust-free workshops and domestic leading machinery and equipment, which provides a hardware foundation for precise control of the sintering environment. Especially in the sintering process of magnetic materials, high-precision temperature control systems and automated production lines are used to ensure that the sintering conditions of each batch of products are consistent, thereby stabilizing product quality.

• Professional R&D team: HANKER's R&D team is composed of experts in materials science, chemical engineering and other fields. They not only have profound theoretical knowledge, but also have rich practical experience. Through continuous experiments and optimization, the team has established a detailed sintering process database, which can accurately set the sintering temperature and time for different material formulations and application requirements to achieve the best performance balance.

• Strict quality control system: From raw material procurement to finished product delivery, HANKER implements a complete set of strict quality control processes. In the sintering process, online monitoring technology is used to record and analyze the temperature curve and time nodes during the sintering process in real time to ensure that each flexible magnetic sheet can meet the preset performance standards. In addition, the company also regularly calibrates and maintains the sintering equipment to eliminate the impact of equipment errors on product quality.

• Application of innovative technologies: HANKER continues to explore and innovate in sintering processes, such as using atmosphere sintering technology to further optimize the microstructure and performance of the material by precisely controlling the gas composition in the sintering environment. At the same time, the company is also committed to the development of new magnetic materials to improve the comprehensive performance of flexible magnetic sheets and meet the market demand for higher quality products.

• Integration of industry, academia and research: HANKER adheres to the path of integration of industry, academia and research, establishes long-term cooperative relations with many universities and research institutions, jointly carries out basic research and application development of magnetic materials, continuously transforms the latest scientific research results into productivity, and promotes technological progress in the industry.
