The production process of metal refrigerator stickers generally includes the following steps:

Design

Determine theme and pattern: Design the pattern and design of refrigerator stickers based on customer needs, market trends, or specific themes. For example, if designing refrigerator stickers for tourist souvenirs in a certain city, it may incorporate elements such as the city‘s iconic buildings and unique landscapes; If it is to promote a certain brand, it will be designed based on the brand‘s logo, featured products, etc. The design process can use professional graphic design software such as Adobe Illustrator to ensure the clarity and accuracy of the patterns.

Consider size and proportion: Determine the appropriate size and proportion based on the purpose and expected effect of the refrigerator sticker. Generally speaking, refrigerator stickers should not be too large or too small, and should be displayed clearly on the refrigerator without affecting its use and appearance. At the same time, the coordination between the pattern and the overall size should also be considered to avoid situations where the pattern is too crowded or empty.

Mold making

Choose mold materials: Common mold materials include steel, copper, aluminum alloy, etc. For the mold of metal refrigerator stickers, steel with high hardness and good wear resistance is generally selected to ensure that the mold can withstand multiple stamping or die-casting operations without deformation.

Mold making: Based on the designed pattern, use CNC machining equipment or traditional mechanical processing methods to process the mold material into the desired shape and size. During the processing, the accuracy of the mold must be strictly controlled to ensure that the size and shape of the mold are completely consistent with the design drawings. For example, for some complex patterns and shapes, special processing methods such as electrical discharge machining may be required to ensure the accuracy of the mold.

Preparation of metal materials

Choose metal materials: Select suitable metal materials based on the design requirements and cost budget of the refrigerator sticker. Common metal materials include iron, copper, zinc alloys, stainless steel, etc. Different metal materials have different physical properties and appearance effects. For example, iron materials have lower costs but are prone to rusting; Copper materials have good conductivity and thermal conductivity, and also have a textured appearance; Zinc alloy materials have high strength and good formability, making them suitable for making complex shapes.

Smelting and refining metals: If the selected metal material is supplied in the form of ingots, it needs to be heated to a molten state and refined to remove impurities and gases from the metal, in order to improve its purity and quality. The melting process needs to be carried out in a high-temperature furnace, and the melting temperature and time should be strictly controlled to ensure that the metal material can be fully melted without excessive oxidation.

forming

Stamping forming: Pour melted metal material into a mold, and then use a stamping machine to stamp the mold, so that the metal material is formed into the shape of a refrigerator sticker under the action of the mold. During the stamping process, it is necessary to control the stamping pressure and speed to ensure that the shape and size of the refrigerator sticker meet the requirements. For some simple shapes and patterns, stamping is an efficient and low-cost molding method.

Die casting: For some complex shapes and patterns, die casting may be necessary. Die casting is the process of injecting molten metal material into a mold under high pressure, allowing the metal material to rapidly solidify and form within the mold. The advantage of die-casting molding is that it can be produced
