Customized badge processing technology is generally divided into stamping dies, aluminum die-casting, hydraulic press, etching, etc., among which stamping dies and aluminum die-casting are more common. The coloring process is divided into cloisonné enamel (cloisonne), imitation cloisonné enamel, spray paint, crystal glue, packaging and printing. The materials of the stamp are generally divided into zinc alloy materials, copper, stainless steel plates, iron, silver, pure gold and other alloy products.
Stamping die stamp: Generally, the raw materials for stamping die stamping are copper, iron, aluminum, etc., so it is also called a metal badge. The most common is the copper stamp. Because copper is softer, the wire frame pressed in is the clearest, and the iron stamp 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 the zinc alloy materials, the introduction of abrasive tools after heating can make it difficult to make Large embossed motifs and hollow carved emblems.
How to distinguish between zinc alloy materials and copper stamps
Zinc alloy materials: light weight, slanted trimming and smooth and flat
Copper: trimming has The punching mark is heavier than zinc alloy materials with the same volume
Generally, the parts of zinc alloy materials are riveted, and the parts of copper are solder and silver
Crimson enamel sign: The cloisonné enamel seal is also called the cloisonne seal, which belongs to the high-end seal processing technology. The raw material is mainly red copper, 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 color tone is dark and single, which can be preserved, but the cloisonné enamel is easy to break and cannot be struck 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 the 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 gorgeous, but it cannot be stored for a long time. After three to five years, the color will turn yellow after high temperature or ultraviolet radiation.
Paint-baking craftsmanship: the three-dimensional effect is obvious, the color tone is beautiful, and the metal material wire frame is clear. 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. The 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 stamps. 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 protect the surface from scratches. A layer of fully transparent maintenance epoxy resin on its surface, which is called Poly, is often referred to as 'Crystal Epoxy'. After the epoxy resin is used, the zhengzhang will not have the layered feeling 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.
