Straightening machines (often known by their nickname of straighteners) are mechanical devices designed to correct and align materials such as metal bars, tubes and sheets in various industries such as manufacturing, construction and automotive. Straightening machines serve the primary function of eliminating distortions or deformities that have arisen as part of the production, transportation or storage processes. This machine applies controlled pressure and force, gradually straightening out and returning material back into its original state. Straightening machines come in all forms and sizes, from manual hand-held tools to complex automated systems, depending on the nature and complexity of straightening tasks. Straightening machines play an integral part in maintaining materials used across industries for applications ranging from quality assurance and functionality testing, through safety certification processes to product integrity assurance programs.
