Printing with eco-friendly PVC substrate and eco-friendly paint effectively avoids such problems and ensures that the product meets environmental requirements from the raw material stage.
• Metallic materials: When producing metal refrigerator magnets, it is important to choose high-temperature resistant metals such as copper and silver as enamel base. Iron, zinc and other metals are easily corroded in the process of high temperature combustion, releasing harmful substances and affecting product safety. On the other hand, copper and silver have good high temperature resistance and stability, ensuring that no harmful substances are released after high temperature combustion, and ensuring the product's environmental safety.
• Auxiliary Materials: The choice of accessories is equally important. Using soft magnets, rather than strong magnets, can reduce scratches on refrigerator surface and on the user's hands. At the same time, adhesives, printing inks and other auxiliary materials must comply with RoHS standards. RoHS standards restrict the use of six harmful substances, lead, cadmium and mercury, to reduce environmental and human health hazards at source.
• Innovative Materials: With the development of science and technology and the diversification of consumer demands, acrylic, wood, silicone and other innovative materials are increasingly used in refrigerator magnet production. These materials are subjected to rigorous environmental testing prior to use to ensure compliance with environmental and safety standards and to provide consumers with safer and safer options.

Security app applications

• Enameling Process: The enamel process high-temperature sintering 850°C, allowing the pigment to fuse fully with metal substrate to ensure a long-lasting and vibrant colour. Low temperature combustion can cause enamel to fall off, not only affect the appearance of the product, but also cause heavy metal migration, posing a threat to human health. High temperature sintering effectively avoids this problem and ensures the safety and durability of the product.
• Baking lacquer technology: Baking paint process uses the method of multi-layer spraying and high temperature baking to treat the surface of baking lacquer, forming a robust protective film on the surface of refrigerator magnet. The protective film can not only improve the abrasion resistance and corrosion resistance of the product, but also prevent the destruction of external factors, prolong the service life of the product and ensure that the product does not release harmful substances during use.
• UV process: UV process using UV curing ink, compared to traditional ink, reduce the emission of volatile organic compounds (VOCs). VOCs are a major source of air pollution with negative impacts on human health and the environment. The adoption of UV process has effectively reduced environmental pollution in production process and conforms to the requirements of environmental protection.
• Epoxy Resin Process: The epoxy resin process is used in epoxy resin process to form water-proof and dust-proof layer after curing. This process not only protects the internal structure and design of refrigerator magnets, but also prevents the release of harmful gases by adhesives. Epoxy resin has excellent sealing performance and stability, ensuring that the product will not affect environmental safety due to adhesion problems during long-term use.

Magnetism test

• Testing criteria: Adsorption and the adsorption force induction strength of refrigerator magnets refrigerator magnet according to GB/ T 24616-2022 standard. For example, magnets are required to keep five sheets of A4 paper together to ensure sufficient adsorption force and stable adhesion to the refrigerator surface.
• Stability test: repeated measurement of magnetic energy by simulating droplets and mechanical vibration that refrigerator magnets may encounter during practical use. Through multiple experiments, the magnetic properties of magnets under these conditions are not weakened and good adsorption performance is maintained.
• Temperature and humidity testing: The magnetism of refrigerator magnet is tested at 20±5°C and 45%-75% humidity humidity. Different temperature and humidity conditions can affect the magnetism of refrigerator magnets, and this test ensures that refrigerator magnet use well under different environmental conditions.

Environmental and safety testing

• RoHS testing: RoHS testing focuses on six harmful substances, including lead, cadmium and mercury, to see if their limits meet EU standards. These harmful substances are commonly found in electronic products and products. Since refrigerator magnets are closely related to people's lives, their content must be strictly controlled in order to protect consumers' health.
• Physical performance testing: Physical performance testing includes several aspects, including size bias (length/width ≤ 2mm, thickness ≤ 1.5mm), color deviation (sample similarity ≥ 80%), and drop resistance. Large size deviation will affect the installation and use of the product; large color deviation will affect the aesthetics of the product; and the drop reflects the damage resistance of the product.
• Child safety testing: For refrigerator magnets that children may be exposed to, make sure there is no risk of small parts falling off to prevent accidental swallowing and suffocation. Child safety is an important aspect of product quality testing and manufacturers must exercise strict control to ensure children's safety.

Functional testing

1. Adhesion Stability: The adhesion of a refrigerator magnet is actually tested on the surface of the fridge to make sure it doesn't scratch the surface of the fridge or fall off easily due to a lack of magnetism. Appropriate adhesion is the foundation of refrigerator magnets normal use, can provide the user with the good use experience.
2. Weather resistance test: simulates high and low temperature environments to verify whether refrigerator magnets will deform or fade under different temperature conditions. Refrigerator magnets are usually placed in environments with high temperature fluctuations, such as kitchens. Good weather resistance ensures that the product maintains appearance and stable performance in different seasons and environments.

Domestic standards
GB/T24616-2022: This standard is the core standard for the magnetism and stability of refrigerator magnets. It provides a clear specification and testing basis for the magnetic properties of refrigerator magnets magnets, ensuring that the product's magnetic properties meets safety requirements.
