Stamping is the production technology of product parts with certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the sheet metal is directly subjected to deformation force and deformation in the die.
Stamping is a method of metal cold deformation processing, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing).
“Hardware stamping products – tokens and medals”
“Hardware handicraft” stamping parts refer to the tools or handicraft made by processing and casting gold, silver, copper, iron, tin and other metals to fix things, process things, decoration and so on. What kinds of stamping parts of Hardware handicraft are there?
1. Tin parts – tin is not widely used. The common tin parts are canned bottle caps, tin paper, plastic bottle tin seals, etc.
2. Gold articles – As we all know, gold is a valuable precious metal with a value of 385 yuan per gram. Most of them are deposited in the national treasury for good preservation. Most of them are gold. Gold is naturally used to make valuable goods. Gold casting objects are usually jewelry, money, substitute money and other items, such as rings, necklaces, gold coins (ancient times), bricks, bars, etc. There are also some objects used to make celestial spheres and other objects.
3. Iron castings-iron has a very wide range of applications, and its content in the world is very large: the proven reserves of iron ore in the world have exceeded 200 billion tons! There are two kinds of iron commonly used: hematite and magnetite.
Hematite: The composition of hematite is iron oxide, which is dark red or steel gray. It uses cast iron nails, screws, nuts, hammer heads, machine parts and so on.
Magnetite: Magnetite is magnetic, also known as “magnetite”, “magnetite”. Magnetite is not as widely used as hematite, but also useful. Magnetite can be stereotyped into magnetite identification object.
4. Silver-silver is silver-white, and it is also a precious metal. In ancient China, it was used to make silver treasures or broken silver for national expenditure and daily trading. Ancient Egyptians used silver as silver tablets to treat wounds by using its water-soluble silver ion bactericidal effect. Modern silver is also commonly used in jewelry processing. Silver has excellent conductivity and heat transfer performance. Common industrial silver parts are usually parts of electronic instruments and power generation equipment, such as silver core wires.
5. Copper is the messenger of human civilization. Ancient people often used copper to make ritual utensils, such as copper tripod and modern tools. As we all know, copper has excellent electrical conductivity, second only to silver, but copper ore is more and cheaper than silver ore. Copper is often used to make wire cores and parts of communication equipment and electronic equipment.
