Badges, in short, are signs worn on the body to indicate identity, profession, and honor. It has a long history, and its origin can be traced back to the totem signs of tribes and tribes in primitive society. The badges really have written records, and they originated in our country. 'The Warring States Policy·Qi Ceyi' records: 'Qin false roads and Han Wei to attack Qi. King Qi Wei made Zhang Zi to respond to it... Zhang Zi changed his badge to mix with the Qin army.' This is the earliest written record in our country An example. But the badge referred to here is essentially different from the badge in the current sense. It actually refers to the flag. Gao You's Note: 'The emblem and the name of Chi are also...changed to make it the same as the Qin Qi and Zhang.'. In recent years, the collection value of badges has become more and more prominent. In particular, badges and medals made of metal materials have become the mainstream of badge making. The so-called metal badge is made of copper, iron, zinc alloy, gold and silver and other metal materials through a certain badge process.
Copper is the metal of choice for making high-end badges. Among them, copper is used for the production of enamel badges, and brass and bronze are mainly used Produced in metal badges such as imitation enamel badges and painted badges. Copper is a relatively soft metal material. It uses more materials to make metal badges. The metal badges produced are beautiful in appearance and high in quality. The general thickness is 1.2 mm, 1.5 mm or 1.8 mm, and the thickness of the medal is generally 3 mm. .
iron is the most common material. It has a characteristic of good hardness and relatively cheap price, so it is made of iron The price of the metal badge is much cheaper, and the effect of plating or baking on the surface of the iron badge is very similar to that of the copper badge, and it also has a better texture.
3. Zinc alloy
Zinc alloy is the best material for die-cast metal badges. Zinc alloy has several characteristics and is very suitable for making metal badges, three-dimensional badges and double-sided commemorative coins. A-Good casting performance, it can die-cast complex shape, thin-walled rice dense parts, the surface of the casting is smooth; B-The surface can be electroplated, painted, sprayed, etc.; C-does not attract iron or stick molds during die-casting; D- It has good mechanical properties and abrasion resistance at room temperature; E-melting point is low, melting at 385 degrees, easy to die-casting and so on. In badge production, in addition to metal badges made of copper, iron, zinc alloy, stainless steel, and stainless iron, there are also metal badges made of precious metals such as gold and silver and aluminum.
Technology and technology, improvement is endless. Improvement is a process of continuous investment. The lean change in the production of sports medals and anniversary metal badges is not a simple change in management. It is the change of thinking mode and corporate culture from top to bottom. As a certain manufacturing company, we seize the opportunity to deeply integrate process technology and manufacturing technology, improve manufacturing strength and influence in the industry, and establish a metal craft gift brand.
