Itasonic 2010© utilises the Sonic Resonance method for non-destructive controls on raw or processed metallic, ceramic or sintered parts.  

            Sonic controls are based on a precise principle of physics: every type of part has its own resonance frequency that generates a unique characteristic curve. The resonance frequencies in fact depend on clearly defined factors:

•    Weight
•    Structure
•    Form
•    Integrity
•    Chemical composition
•    Mechanical characteristics

The resonance curve will be practically identical for all of the pieces, which conform to the specifications. It will change in presence of variations to the above listed parameters.

Advantages of the sonic control
•    Quick and easy to use.
•    It controls the entire part.
•    It does not require immersion in liquids, cleaning, washing, drying, demagnetisation, etc...
•    The result of the test does not depend on the operator.
•    Easily inserted in production lines.
•    Easy and quick type change.
•    Significantly reduction  of the costs of control.
•    Fast return of the investment.

Main field of application for the sonic control
•    Automotive – brake system components and components for safety in general.
•    Heat treatments.
•    Aluminium die castings.
•    Brass molding.

Part suited for sonic control
•    Aluminium die casting parts.
•    Sintered parts.
•    Spheroidal cast iron.
•    Brake pads.
•    Molded parts.
•    Industrial ceramic.
•    Parts that require 100% integrity control.

Some examples
•    Valves in general.
•    Hubs, Pinions, Pulleys, Connecting rods, Gears, Cams.
•    Arms supports (steering, suspension, etc…).
•    Synchronizer rings.
•    Pump bodies.
•    Brake discs and Brake drums.
•    Brake pliers.
•    Brake pads.
•    ABS rings.
•    Components for turbo compressors – rotors and nuts.
•    Parts subjected to heat treatments.

Itasonic 2010© is used for:    
•    FRF Analisys, to test the vibration frequencies, or Natural Vibration Frequencies: a requirement which has become fundamental for components in vehicle braking systems. Itasonic 2010© verifies the project specifications, obtained through modal analysis, referring to appropriate tolerances that can be set.
•    To find structural defects such as variation of shape and weight (parts with incomplete forms, casts or sintered), presence of cracks, stress cracks or discontinuity (Aluminium die casting parts), density differences and elasticity modules (controls on % of nodularity in spheroidal cast iron parts), presence of oxidation and contamination (e.g. presence of iron waste in sintered aluminum parts), inclusions, stripping of the material.
A fundamental requirement in the application for defect control is that the sonic system must be able to recognize at least one frequency, among the resonance ones, which allows the separation of good pieces from rejects. This activity is necessarily experimental and must be performed at a preliminary level with a simple procedure of Itasonic 2010© software.
