forging of metal metallurgical plants all over the world are engaged in metal forging this process makes it possible to achieve the desired shape and size using impacts a variety of non ferrous and ferrous metals can be processed aluminium and it's alloys copper titanium and also iron are the most common there are two types of forging cold and hot in this case hot forging is shown heat is used to make the workpiece smooth and flexible in each case the heating temperature is different depending on the size of the metal part the hardness and the type of metal during the first stage of processing the workpiece is heated and special furnaces are used for this they can be combustion and continuous furnaces sometimes soaking pits and electrically heated furnaces are used it should be noted that the piece must be heated gradually and uniformly only in this way can internal tension in the metal be avoided the next stage of processing is called swaging the workpiece is subjected to an impact so the metal is compacted and the vacuum disappears the processing equipment is called a hammer this is a 14 machine with a strike mass ranging from one kilogram to 5000 or even more the record is 300 tonnes it should be noted that during the process there are inevitable Mills scales which fall off on their own or are knocked down with the help of the crowbar and then cleaned up with a broom that's why the metal is usually moulded larger and heavier than necessary assuming it will lose size in the fortun process diamond mining here we can see the Diavik diamond quarry located in Canada 300 kilometers northeast of the city of Yellowknife every day thousands of tons of stones have blown up in search of diamonds after blasting the excavator scatter stones that are more than two and a half billion years old to reach the kimberlite point this is the name of the geological body formed as a result of the ancient advance of magma through the Earth's crust where the diamonds are found the volcanic or extracted from the pipe is loaded onto a 240 tonne dump truck curiously although the ore at this stage looks like a pile of common stones each contains up to 700 carats of diamonds in this condition these stones are sent to production while processing begins the first stage crushing is carried out with the help of special machines large stones are crushed to obtain smaller stones but without damaging the diamonds during this stage the rocks become a mixture of small stones some of them precious but most of them are rubbish in the last stage the stones are divided into small Lots and then submerged in hot chemical baths after the bath the rough diamonds are taken out the creation of bells here we have the Royal Arch Bounce foundry located in the Netherlands and built in 1872 it should be noted that since then the technology of manufacturing bronze bells has not changed much in the first stage the master depending on the size of the Bell he wants to create forms the external and internal moulds then they come together the internal mold is inserted into the external the space formed between the molds is filled with molten bronze as soon as the metal cools the molds are removed and the Bell is ready interestingly the most difficult stage in the creation of the Bell is the manufacturing of the molds the material used is clay which has applied layer by layer until it acquires the desired shape and size the masters admit that the process is more complicated than it seems if you over tighten the clay the mold will fall apart if it's not sized enough it also crumbles when the mold of the dome is moulded it's covered with a layer of graphite then the mold is sprayed with sand forming a new layer it has exactly the same size as the future Bell when this layer is ready it's covered with wax the resulting structure is placed in the tank filled with sand with additives and left for a couple of days for contraction after a few days the tank is turned over and lifted inside the sand forms an outline which is then used to make the outer mold the sand layer is removed from the inner mold as it's not needed now you can start creating the bell the shapes are combined so that the space between them coincides perfectly with the shape of the future bell the bronze is poured so hot that it takes two weeks to cool down that's the process doesn't that they're the almost finished Bell goes to the last processing department where it's polished in different places so that it finally has five notes creation of lava lamps these decorative lamps are assembled in two parts the upper part is made of glass and the lower part of plastic or metal the construction of the glass part of the lava lamp starts at the factory where hot air is blown into a container filled with hot glass the air fills the mold so that the glass is distributed on the walls and takes the desired shape keep in mind that the glass part is something like a bottle the machines in the workshops stand out for their extraordinary productivity creating up to six thousand bottles per hour if the glass cools too fast it will crack so the bottles are placed on the conveyor and then move through a tunnel with straights temperature control which gradually cools the material at the same time the aluminium bases and details for the lamps are made in another workshop the metal sheets are cut into circles then cold Forge to the desired shape in the meantime the bustles begin to fill the liquid consisting of water dye and chemical oil is poured into the interior wax is also put inside the secret is that at room temperature the wax sinks as it's heavier than the oil and floats to the surface at the top of a lamp the wax then cools sinks begins to heats up again and so on creating a cycle to heat the wax and incandescent lamp is used which is placed in the base before the final assembly the bottles filled with liquid and wax are placed in a hot bath so that the wax melts and becomes our liquid production of Stressless chairs the norwegian company a cornice a sa is creating special chairs that adapt to the position of the human body providing maximum comfort the secrets of these chairs is their design features the production process is not easy though but the plant produces up to 1250 chairs per day in the first stage a round elastic and durable base is created trees known as European beaches are used for their manufacture the layers of wood had dried so that there's no moisture in them and then glued together the rest of the work is then done by robots as it's quite dangerous for humans the glued layers of wood are treated with a press to give them a rounded shape then they're cut and fold it to form a circle another robot joins the likes to this circle and the resulting element is painted in addition to create the frame metal and plastic event together the wood base and metal skeleton begin to resemble a chair the soft part consists of a dense foam layer upholstered with a soft foam layer a cowhide lining is placed over the resulting detail please note that each lining is hand laid the air is extracted from the foam to reduce its size and facilitate the installation of the lining hey stop being lazy it's time to use that brain of yours welcome to brain time incredible facts from the past the present and even the
