Microscan is a company that likes to give back to the community and strongly believes in supporting local science and technology education. Microscan hosted a Science and Technology Day at a local Massachusetts public middle school. Over 50 6th graders took part in an interactive day learning about barcodes and illumination. Kyle O’Brien, Microscan’s Manager of Product Management, and Thomas Driscoll, Microscan’s Engineering Manager located in Nashua, NH traveled to the McCarthy Middle School in Chelmsford, MA to educate these 6th grades on imaging, barcode and lighting technology.
Because Microscan has a specialty product line for reading 2D direct part marks (Hawk products) we are often asked by our customers to recommend what marking methods are best to use. Particularly with metal parts, clear and consistent marking is critical and this give an overview of four common methods.
There are many methods to directly mark objects. Selecting the best method for the application is critical to achieving success. Since each method has its own advantages and limitations, it is important to review and experiment with as many methods as possible before selecting the appropriate one.
Common methods for marking metal substrate include electro-chemical etch, laser etch, and dot peen on regular or machined metal.
