The manufacturing process of custom badges is generally divided into stamping dies, aluminum die-casting, hydraulic press, etching, etc. Among them, stamping dies and aluminum die-casting are more common.
The coloring process can be divided into cloisonné enamel (cloisonne), imitation cloisonné enamel, spray paint, crystal glue, packaging printing, etc.
The materials for the stamp are generally divided into zinc alloy materials, copper, stainless steel plates, iron, silver, pure gold and other alloy products.
Stamping die stamping: Generally, the raw materials used for stamping stamping die stamping are copper, iron, aluminum, etc., so it is also called a metal badge.
The most common one is the copper seal. Because copper is softer, the wire frame pressed in is the clearest, and the iron seal is second. The relative price of copper is also more expensive.
Aluminum die-casting stamp: The aluminum die-casting stamp is generally made of zinc alloy materials. Because of the low melting point of zinc alloy materials, abrasive tools are introduced after heating. , Can make complex and difficult relief patterns and hollow carved seals.
How to distinguish between zinc alloy materials and copper stamps
Zinc alloy materials: lightweight, beveled and smooth Leveling
Copper: the cutting edge has scoring, the same volume is heavier than zinc alloy material
of general zinc alloy material The parts are riveted, and the copper parts are solder and silver
The cloisonné enamel seal: the cloisonné enamel seal is also called the cloisonne seal, which belongs to High-end stamp processing technology.
The raw material is mainly red copper, which is colored with cloisonné enamel powder. The characteristics of making the cloisonné enamel seal must be colored first and then polished with terrazzo and electroplated, so it feels smooth and flat.
The tones are all dark and single and can be stored, but the cloisonné enamel is easy to break and cannot be hit or dropped by force. Cloisonne enamel badges are more common in army medals, badges, medals, car number plates, car signs, etc.
Imitated cloisonné enamel seal: The processing technology is basically the same as that of the cloisonné enamel seal. The only color is not the cloisonné enamel powder, but the resin paint, also called color. Paste color paste. The hue is brighter than cloisonné enamel and has a glossiness
. The surface of the product is smooth to the touch, and the wall or material can be made of copper, iron, zinc alloy materials, etc.
How to distinguish between cloisonné enamel and imitation cloisonné enamel: real cloisonné enamel has a sense of porcelain layering, with less color options and a hard surface. It is not easy to leave marks on the surface with a needle, but it is very easy to break.
The imitation cloisonné enamel material is soft and can be pierced into the fake cloisonné enamel with a needle. The color is bright, but it cannot be stored for a long time. After three or five years, it will be exposed to high temperature or ultraviolet light. Irradiation, the hue will turn yellow.
Paint baking process signature: significant three-dimensional impression, beautiful color tone, clear metal material wire frame. The concave part is filled with spray paint color paste, and the convex part of the metal material wire frame must be solved by electroplating process.
Materials generally include copper, zinc alloy materials, iron, etc. Among them, the price of iron and zinc alloy materials is low, so there are more common paint signs. The processing process is the electroplating process, then coloring, baking, and the production process of cloisonné enamel.
The spray paint stamp is in order to better store it for a long time and prevent the surface from being scratched. A layer of fully transparent maintenance epoxy resin on the surface layer, which is called Poly, is often referred to as 'Crystal Epoxy'.
After arriving at the epoxy resin, the stamp will not have the layered feeling of the convex and concave of the metal material. But Polly is also very easy to be scratched, and after UV exposure, Polly will turn yellow after a long time.
Packaging and printing stamp: general Two methods: ink printing and tablet packaging printing. It is also generally called the crystal glue seal, because the final process of the seal is to add a layer of transparent maintenance epoxy resin (Poly) on the surface of the seal.
The raw materials used are mainly stainless steel plates and brass. The thickness is generally 0.8 mm. The surface layer is not solved by electroplating process, and the original color or metal drawing is used to solve it.
The key to ink printing stamp is simple graphics and less tones. However, tablet packaging and printing has complicated pattern designs, many tones, and patterns with gradual color gradients.
