Dr. Frigz International uses four different types of welding technologies throughout its manufacturing facilities. The choice of technology depends upon the material, profile of the workpiece, and technical requirement of the instrument. Spot Welding: This is a form of electric resistance welding. Two brass electrodes are used to ‘spot weld’ together two sheets of metal …

If you remember our previous post we mentioned that stainless steel (S.S) is not completely corrosion free and that it should be more rightly called stain-resistant than stain-less. We also mentioned that the corrosion resisting power of S.S can be increased by doing passivation process. well, what is passivation process anyways? Passivation is a chemical …
These days surgical Instruments are made from a variety of materials including composites, plastics, titanium, and (the more traditional;) stainless steel. Typically two types of stainless steel series are most commonly used for instruments manufacturing. 300 series (Austenitic) stainless steel, and 400 series (Martensitic) stainless steel. The Austenitic steel cannot be hardened through heat treatment. …
