The dry electropolishing technology is a novel electrochemical process that improves the result of current finishing technologies. It overcomes the barriers of liquid electropolishing and abrasive polishing using solid particles that act in a localized manner at each point of the surface, to remove material by ion exchange.
As it is a non-abrasive treatment it does not round off the edges and avoids a lack of effect on internal corners because of reduced movement and energy.
Some of the most important applications of our technology for medical device industries are:
- Mouth and jaw implants
- Shoulder joints, arm plates and hand implants
- Vertebrae/spinal implants
- Hip, hip stem, hip femur head implants
- Acetabulum and pelvis implants
- Upper leg, upper knee, lower knee and ankle joints
- Stents and needles
- Medical device components such as tubes and fittings
- Medical instruments such as cutting bone blades
Current surface finishing solutions tend to present some issues, as they are error-prone. It is hard to certify a specific success-scale as they do not offer consistency on results.
Those processes are not enough reliable and require additional manual rework to achieve the desired finishing, manufacturing also implies the scrapping of faulty parts. Moreover, this equipment requires additional costly peripheral equipment to treat the water and sludge contaminated with metals that require specific maintenance and negatively affecting our environment.
A severe incidence in manufacturing different medical devices refers to the large variety of post-processing steps, even involving manual labor or complex multistep processes. Since the goal is improving QoL and health condition, products must be manufactured in a way that prevents the patient from additional risks.
Some parts just need to be slightly rounded and clean, and many of them need intensive processing, so they have to be polished to work correctly. If a medical product is manufactured negligently or without considering surface quality, it can cause corrosion, premature fracture and consequent rejection. Corrosion, in this case, is causing metal to enter the patient’s bloodstreams and resulting in blood poisoning.
