Fire extinguisher and oxygen cylinder engraving machine, this product is for Arian Sanat Hak Company. As the name of the product suggests, the molds are used in factories producing oxygen gas tanks and fire extinguishers.
Fire extinguisher and oxygen cylinder engraving machine
The fire extinguisher tank engraving machine is used to engrave specifications, logos and symbols on the metal body of the cylinders. Among the engraving capabilities on fire extinguishers, we can mention the engraving of serial numbers, engraving of standard logos, engraving of tank weight through communication with a digital scale, engraving of tank size, engraving of production date and expiration date and other expressions. One of the positive features of this machine is that the tank engraving machine does not have many restrictions regarding the dimensions of the produced tank. In addition to engraving on cylindrical parts, this machine also has the ability to engrave on various flat parts.
Application of engraving machine
The oxygen cylinder engraving machine is an example of an impact engraving machine on metal. Of course, this machine can also be used with a scratch engraving unit (HA300). This allows for engraving with greater depth and higher quality. This valuable feature has been considered by many tank manufacturers. Because these tanks are painted after the engraving operation, and after the paint coating, the writings and signs must remain clear and legible.
How the engraving machine works
In this machine, the tank is placed upright and rotates automatically, and the engraving operation is performed on its body. But if we want to look a little more closely at how the machine works, we need to look at its four main mechanisms. The first and second mechanisms of this machine are having a suitable chassis and a sliding table to hold the capsule in an ideal position so that the engraving operation can be performed on the metal body of the capsule.

Another feature of this machine is that it is equipped with an engraving unit with the ability to adjust the angle for diagonal engraving. In this way, the engraving tool is completely perpendicular to the surface. Otherwise, characters and other shapes will not be engraved accurately on the capsule body. The last feature is the rotary axis by which the capsule is rotated.
