Our manufacturing procedure contain on following steps;
Selection of raw material like stainless steel. Stainless steel available in different grade, Pakistani local and imported from Germany, France, Japan.
MAGNETIC STAINLESS STEEL
For gripping Instruments like Forceps, Tweezers, Retractors
for cutting instruments like Bone Rongeurs, Chisels, Gouges, scissors ,needle holders
for high grade cutting instruments like scissors, Bone Ronerurs
for cutting high quality instruments like cutely and measuring instruments
NON MAGNETIC STAINLESS STEEL
for Cannula, Clamps, Holders, Spreaders, Suction tubes
By hand as well as hammer forging.
MILLING AND TURNING
Cutting away the unnecessary material by milling machines.
FILLING, GRINDING & SETTING
Removing of irregularity by grinding wheels and files so instruments develop its final shape.
Heat treatment is significant process to improve performance and strength of instruments.
Chemical treatment clean surface of steel and increase rust resistance
MAIN PROCESS AS BELOW:
Pickling is done after heat treatment process to use dilute sulfuric acid/Nitric Acid.
The passivation process is done when free iron, oxide scale, rust, iron particles, metal chips adversely affect the stability of the surface and this process contains of immersing stainless steel instruments in a solution nitric or citric and sodium dichromate, dissolving the imbedded iron particles and restoring the original corrosion-resistant surface by forming a thin, transparent oxide film.
Passivation also is accomplished by electro polishing
Electro polish is an excellent electro chemical process, passive surface of stainless steel instruments more than other methods because metal gives a bright surface due to this process.
Spare burr also removed by electro polish process
Usually phosphoric and sulphuric acid are used in conjunction with high current density to clean and smooth surface of metal
FIXING AND FITTING
Setting is done to aligning, fixing and fitting the instruments with accurate function.
POLISHING / BUFFING
Metal finishing process done by using different abrasives (grinding, cutting, brushing, felting, buffing wheels) to create a homogeneous surface and finalize appearances of instruments like shine /mirror/bright or dull/satin/matte.
To make sure quality of instruments per desired specifications final checking /inspection done by qualified technician.
Marking/Printing process done by laser marking system.
