Lock former is also called lock former machine, which is a former of lock bodies with the cold forging mechanism that make the lock case well. Now most of the door locks for ordinary usages are made with either steel or copper, while these two still contains some complementary benefits that the other side cannot cover totally.
For steel lock casting, steel casting is similar to iron casting in many ways, and in the metal working industry, iron casting, or cast iron, is a metalworking process that produces a group of iron-carbon alloys with carbon content greater than 2%. Its usefulness derives from its relatively low melting temperature.
The metal alloy constituents affect its color when fractured, that is, white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and will initiate countless new cracks as the material breaks.
In the industry, cast iron is a group of iron carbon alloys with carbon content greater than a certain level of percentage. Its worth derives from its relatively low melting temperature. The alloy constituents affect its color when fractured, that is, white cast iron has carbide impurities which allow cracks to pass straight through. On the other hand, grey cast iron has graphite flakes which deflect a passing crack, and that initiates countless new cracks as the material breaks. Furthermore, ductile cast iron has spherical graphite nodules, which stop the crack from further progressing so are considered practical in the industry.
Some locks are made by bronze that are easy to use and are also welcomed by many consumers. Bronze casting is the casting process of bronze materials into a mold or other cavities. Casting process, when it is in the metal working, is a manufacturing procedure that a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then the hot and liquid state materials are allowed to solidify as a sturdy formed shape.
There are a wide variety of casting processes in the metal working industry. For human civilization, when people went into the age of Bronze Age, there were mainly two forms of bronze that were commonly seen. The one is the classic bronze, which is about 10% of tin, and was utilized in casting. And the other is the mild bronze, which is about 6% of tin, which was hammered from ingot shapes to make sheets. Bronze materials were used as weapons since its inception.
Bladed bronze weapons were often cast from the first type, the classic bronze, and the helmets and armor items were hammered from the second type, the mild bronze. It is obvious that the handling of bronze was very early and for both types of bronzes was well managed by ancient people in the old days for their processing goals. For the bronze casting to be done, there are still many other following procedures. One final step is conducted after the final polishing. After this polishing step, the corrosive materials may be used to form a patina.
Patina is a process that permits some manipulation over the color and the finish of the bronze objects. Another form of sculptural art that utilizes bronze is called ormolu by experts. The thing ormolu is a well cast soft bronze which is gilded to produce a matte gold finish. This method was very popular in the days of the 18th century and all these casting methods are involved with a series of movements that includes serious knowledge of physics and material science. Users need to know more before they act in order to make sure that the following steps are confirmed to be safe for their safety issues.
Cold forging of the casted lock cases is a cold forming of metals in progressive series of steps into rigid shaped forms or other orientations. This kind of method is much like cold heading in which the heading of the bolts are achieved with normal temperatures that is not different from the circumstances. Cold heading machines can do heading process on the metal bolts, which is a metalworking procedure that incorporates the forging, extruding and upsetting processes. This process is specifically carried out on metals while they are in the cold status, resulting in cold working like lock formers do.
