Technological processes

The manufacturing of prosthetic suprastructures for surgery mainly comes to a small-lot or even piece-work production depending on the customer requirements and wishes to a greater degree than on the production standards. The engineering and design of these medical products are the most important constituent of the entire manufacturing process. They should be already treated as a critical organizational technology, which final result (product) is the absence of the right to make mistakes at all following manufacturing stages. It presents a complicated multiple-stage and very specific process of design engineering, coordination of customer needs with the equipment capabilities, verification nature and laboratory tests.

The surface machining of medical implants and prosthetic components has a specificity of its own because it is not aimed at the increase of accuracy class of the part surface, but at the increase in the survival of metal implant to a biological tissue. A guarantee of this surface property lies in its sufficient roughness and porosity as well as the absolute chemical purity of biologically neutral material.

 

 

 

• electromagnetic barrel finishing for small-sized parts with complicated shape (like jewellery and surgical ones) is an analogue of mechanical polishing. It is used to smooth burrs and sharp edges occurred in the process of part machining, thorough metal surface cleaning (even in hard-to-reach places) of oxides, various contamination and greasy deposits;

• sandblasting performs one more essential function while cleaning a metal surface from oxide film, that is imparts it a required roughness being necessary for optimization of the implant survival to a living tissue;

 

• acid treatment (etching). It is used both for the attainment of required chemical purity by the surface of metal implant (removal of residual contaminants after machining) and for the imparting required porous structure to it, which, in its turn, adding roughness, exerts influence on the quality of the titanium surface survival to a living tissue;

• ultrasonic cleaning (cleaning with ultrasonic waves in liquid medium) is a final stage of fine cleaning of the product surface as the result of which the most hard-to-reach places and even the pores of material are cleanedwith the absolute chemical purity being imparted to it. At the ABM Technology Plant, an ultrasonic cleaning can be carried out in six different media (baths) - acid, alkaline, alcohol, cleaning water solution, and clean water

 

At the ABM Technology Medical Product Plant, even packaging of finished products is
an important part of manufacturing process. Even its primary packaging takes place in the isolated so-called “clean room” with the observance of the highest sterility standards. The strictest mode of bactericidal processing, including air filtering is maintained in this manufacturing area. The employees wear insulating work uniform and carry out product primary packaging only with the help of sterile instrument without contact with the hand skin of packers.

After primary packaging, the products are sent to complete sterilization with the hard gamma-radiation completely killing any microbial and bacterial media.
