The surface of the metal keychain can be flat, 2D, 3D, etc.; fluorescent powder is used to make it luminous; taste is added to make it perfumed; the metal keychain can also be attached to accessories like a compass, a thermometer, etc. Promotions are appropriate for a range of businesses, just as home decorations are appropriate for special occasions. Bright colors, a wonderful feel, a strong three-dimensional effect, and good visual effects are all features of metal keychains. Additionally, metal keychains can be used for decorating and advertising. What then is the manufacturing procedure for metal keychains?

The metal keychain's die-casting procedure

The metal keychain is made using the die-casting technique. Die-casting is a type of metal casting in which the molten metal is subjected to intense pressure using the chamber of the mold. Higher-strength alloys are typically used to create metal keychain molds. Die casting, a method used to create metal keychains is somewhat comparable to injection molding. The majority of the metal keychain die castings, including zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and their alloys, are iron-free. A cold chamber die-casting machine or a hot chamber die-casting machine is needed, depending on the type of metal keychain that needs to be die-cast.

The features of a metal keychain made by die casting

Die-cast metal keychains are often only utilized for mass production of several metal keychains due to the high cost of casting machinery and molds. Die-cast metal keychain component production is generally straightforward, only necessitates four primary procedures, and has extremely small incremental costs. Die-casting is the most popular casting process because it is especially well-suited for producing metal keychains. Die-cast metal keychains offer a smoother surface and superior dimensional consistency when compared to other casting techniques. Click here for 3D Hard Soft Enamel Metal Keychain Key Chains.

A non-porous die-casting procedure that minimizes casting flaws and gets rid of pores was developed based on the conventional die-casting metal keychain technique. It is mostly used for processing zinc, which uses a direct injection method to produce more metal keychains with less waste.

The benefits of making metal keychains by die casting

Die-cast metal keychains have the advantage of having exceptional dimensional precision in their castings. This typically relies on the metal keychain's casting material. The inaccuracy rises by 0.002 mm for every subsequent cm, with an average value of 0.1 mm at the initial 2.5 cm size.

The surface of the metal keychain casting is smooth when compared to other casting processes, and the fillet radius is approximately 1-2.5 microns. Castings with a wall thickness of about 0.75 mm can be produced when compared to sandbox or permanent mold casting methods. It is capable of casting the internal structure of metal keychains, such as wire sleeves, heating elements, and high-strength bearing surfaces, directly. Other benefits include the ability to reduce or eliminate secondary machining of metal keychains, quick production speed, casting tensile strength of up to 415 MPa, and the ability to cast metal keychains with high fluidity.
