The production process of metal refrigerator magnets generally includes the following steps:
Design: Use computer-aided design (CAD) software or hand-drawing to design the pattern and shape of the refrigerator magnet.
Material selection: According to the design requirements, select suitable metal materials, such as zinc alloy, aluminum alloy, etc.
Mold making: Use CNC machining or EDM technology to make the mold.
Die casting: Heat the metal material to liquid state, then inject it into the mold, and press the metal material into shape through the pressure of the die casting machine.
Drain: Remove the die-cast refrigerator magnet from the mold, remove the drain and excess metal material.
Polishing: Use a polishing machine to polish the refrigerator magnet to make its surface smooth and bright.
Electroplating: Electroplating the polished refrigerator magnet, such as chrome plating, zinc plating, etc., to increase its surface gloss and corrosion resistance.
Coloring: Use spraying, silk screen printing or pad printing technology to color the refrigerator magnet to make it present the desired color and pattern.
Quality inspection: Perform quality inspection on the colored refrigerator magnet to ensure that it meets the quality standards.
Packaging: Pack the refrigerator magnets that have passed the quality inspection for transportation and sales.
It should be noted that the production process of different metal refrigerator magnets may be different, and the specific production process may be adjusted according to the actual situation.
