Squeezing temperature is the amount of heat applied to a sample during a plastic deformation process. It is the temperature where the material begins to deform, either by stretching, bending or compressing. The temperature is a critical factor in the analysis of the plasticity of materials. It is the temperature at which the material begins to lose its elasticity, and plastic or permanent deformation begins. Squeezing temperature has a great influence on the process of extrusion or drawing of any material.
During an extrusion process, plastic materials such as steel or non-ferrous metals are pushed through a die. The die is heated by applying heat energy at a certain temperature range to make the metals pliable. This temperature range is referred to as squeezing temperature. If the temperature is set too high, then the material will suffer from excessive heat, leading to the formation of cracks and the weakening of the material’s properties. On the other hand, if it is set too low, the material will not be able to be conditioned properly, leading to deformation of the material.
The plastic deformation process is termed “shear” when it is performed at a temperature close to that of the squeezing temperature. This is because the material is heated and then forced through the die, causing it to stretch and break apart. To avoid this detrimental process, the squeezing temperature must be kept to a reasonable level.
When temperatures reach higher levels, the material’s grain structure will change and become much weaker. This is because the material will require energy in order to travel through the die. As this energy is released, the grain structure of the material will become loose and less uniform. This means that the material will become more malleable, which can lead to reduced properties. Therefore, it is important to ensure that the squeezing temperature remains within the proper range.
In order to ensure that the proper squeezing temperature is maintained, rapid cooling techniques can be employed. These techniques depend on the specific material being processed and the production method. For example, in hot extrusion, cooling technology is used to lower the material’s temperature prior to entering the die. This allows for more uniform and consistent results. In addition, the use of a mold release aids in the easing of the metal passing through the die.
In conclusion, the squeezing temperature of a material is a critical factor in the plastic deformation of the material. Too high of a temperature can lead to excessive heat, causing permanent deformation of the material. On the other hand, too low of a temperature can cause the material to not be able to be conditioned properly and the grain structure to weaken. In order to ensure the proper squeezing temperature is maintained, rapid cooling techniques must be employed. This allows for more uniform and consistent results and aids in the production process.
