COATINGS

Plasma spray coating

This coating is essential to improve the integration and fixation of the implant in the patient’s body.
The technique is based on the projection of a metallic or ceramic powder on the implant using a plasma torch.

Robotic plasma installations project metallic (titanium, cobalt-chromium) or ceramic (hydroxyapatite, alumina) powders in single or double layers, in atmospheric (APS) or vacuum (VPS) conditions.

MedicalGroup offers comprehensive expertise and processes in accordance with applicable ISO 13779, ISO 13179 and ASTM standards:
  • all types of implants
    (shoulder, hip, knee, extremities, disc, cochlear implant…)
  • of all sizes
  • on all substrates
    (titanium, stainless steel, cobalt-chromium)
  • with different technologies: atmospheric plasma (APS) or vacuum plasma (VPS)
  • by spraying metallic or ceramic coatings, in single or double layers
The parts to be coated are cleaned beforehand on an automated cleaning line.
They pass through different baths, the parameters of which are strictly controlled.

Masking

The parts are masked so that only the areas to be coated appear.
They are prepared by spraying with abrasive, to ensure the adhesion of the coating.
Plasma cycles run automatically, according to pre-recorded programs and validated parameters.
Once the coating is completed, the parts are unmasked and individually inspected.

Packaging

MedicalGroup packages all types of medical devices, ensuring a high level of traceability throughout the manufacturing process. The parts are cleaned before entering the ISO7 clean room, then checked under laminar flow. If necessary, they can be assembled. They are then sealed in a blister pack or a Tyvek®, PA / PE or aluminum pouch.
Outside the clean room, the implants are labeled and packaged, according to the customer’s specifications.
