The manufacturing process of metal keychain

The metal keychain has various effects, and the surface can be flat, 2D, 3D, etc.; the keychain is made of fluorescent powder to make it luminous; adding flavor to make it scented; the metal keychain can also be put on a compass, a thermometer, etc. accessories. Home decorations are suitable for occasions and promotions are suitable for a variety of industries. Metal keychains have a strong three-dimensional effect, bright colors, a good feel, and good visual effects. Metal keychains also have good decoration and advertising effects! So what is the production process of making metal keychains?

The die-casting process used in the metal keychain

The metal keychain adopts a die-casting process. Die-casting is a metal casting process, which is characterized by applying high pressure to the molten metal using the cavity of the mold. Metal keychain molds are usually made of higher-strength alloys. The process of making metal keychains by the die-casting process is somewhat similar to injection molding. Most of the die castings used to make metal keychains are iron-free, such as zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys. Depending on the type of metal keychain die-casting, a cold chamber dies casting machine or a hot chamber die casting machine is required.

The characteristics of die-casting metal keychain

The cost of casting equipment and molds is high, so die-cast metal keychains are generally only used for mass production of large quantities of metal keychains. Manufacturing die-cast metal keychain parts is relatively easy, which generally only requires four main steps, and the individual cost increment is very low. Die-casting is particularly suitable for manufacturing metal keychains, so die-casting is the most widely used among various casting processes. Compared with other casting techniques, die-cast metal keychains have a flatter surface and higher dimensional consistency.

Based on the traditional die-casting metal keychain process, several improved processes were born, including a non-porous die-casting process that reduces casting defects and eliminates pores. It is mainly used for processing zinc, which can reduce waste and increase the yield of metal keychains by the direct injection process.

The advantages of die-casting metal keychains

The advantages of die-cast metal keychains include that the castings of metal keychains have excellent dimensional accuracy. Usually, this depends on the casting material of the metal keychain. The typical value is 0.1 mm at the initial 2.5 cm size, and the error increases by 0.002 mm for each additional cm. Compared with other casting processes, the surface of the metal keychain casting is smooth, and the fillet radius is about 1-2.5 microns. Compared to sandbox or permanent mold casting methods, castings with a wall thickness of about 0.75 mm can be produced. It can directly cast the internal structure of metal keychains, such as wire sleeves, heating elements, and high-strength bearing surfaces. Other advantages include its ability to reduce or avoid secondary machining of metal keychains, fast production speed, casting tensile strength of up to 415 MPa, and the ability to cast metal keychains with high fluidity.
