Basic information about gięciu
Bending and straightening of the processes of plastic.Bending and straightening of the processes of plastic. Bending is the shaping of metals and plastics, by the induction of persistent strain in the material by using force. Bending may be cold and hot. Bending hot (the material is heated to a suitable temperature, which helps in the later stages of bending) does not require such large forces that occur at gięciu cold (the material is in its optimum temperature). The process of bending the material is modified. The analysis of phenomena occurring during the bending eBay in the following example: for a rectangular rod (płaskowniku) draw horizontal and vertical lines. Płaskownik lost. Rysy after wygięciu will be distorted. Horizontal lines lying in the upper part of płaskownika will be prolonged, and at the bottom of the zagiętego płaskownika - shortened. At the same time, the thickness at the top of the rod zagiętego decreases, while the thickness of the bottom part - increased. Given the above example it must be the line that does not change its length in relation to the original length of the charger. In roughly the position of the layer is thick in the middle of the charger (the value given to a large approximate).
