CASTING

STATE-OF-THE-ART INVESTMENT CASTING FOUNDRY ENSURING PRECISION, RELIABILITY AND COST EFFECTIVENESS

MARLE GROUP has industrial casting capacities specifically adapted to the production of orthopedic implants.

  • Ample freedom of design, notably for shoulder and knee implants
  • Extensive choice of alloys and coatings specific to the medical sector
  • Ability to maintain high dimensional accuracy and fine product details
  • Highly reproducible and stable manufacturing process
  • Specific heat treatments to improve material performance

With two casting production lines, each consisting of an induction furnace and a cluster firing furnace, MARLE GROUP's production facilities can be adapted to accommodate both high and low volume series and a wide variety of product types, offering our customers maximum design flexibility.

FINISHING AND POLISHING

COMPREHENSIVE FINISHING TECHNOLOGIES TO MEET THE STRINGENT REQUIREMENTS OF THE ORTHOPEDIC INDUSTRY

MARLE GROUP has developed a comprehensive range of finishing techniques that deliver extremely high-precision finished products, be it for prototypes or high volume series production.

With several robotic polishing units and over 80 highly skilled polishers specialized in orthopedic devices, MARLE GROUP has one of the largest and most experienced polishing teams in Europe, enabling us to deliver a high-quality service, regardless of production volume.

COATING

COATINGS FOR NEXT-GENERATION IMPLANTS

MARLE GROUP's medical coating technologies improve the biomechanical properties of your implants (i.e. higher tensile strength, resistance to corrosion and wear, osseointegration).

Our medical coatings are specifically designed for orthopedic devices, making use of atmospheric plasma spray (APS) and vacuum plasma spray (VPS) technologies. These coatings can be applied to all types of joint prostheses – hip, knee, spine, shoulder, ankle, elbow, hand, foot, osteosynthesis, etc. – thus improving the biological fixation of your implants in cortical and cancellous bone.

CLEANING AND PACKAGING

CLEANED AND PACKAGED IMPLANTS, READY FOR STERILIZATION

MARLE GROUP provides comprehensive cleaning and packaging services in our clean rooms, rendering your implants ready for sterilization.

These capabilities enable us to offer our customers a turnkey service that streamlines your manufacturing process flow while meeting stringent quality requirements.

MARLE GROUP's production lines are equipped with automated chemical or ultrasonic cleaning stations that guarantee maximum microbiological safety for the implants produced, which are therefore directly ready for sterilization.

Packaging operations are carried out in controlled atmospheres or clean rooms:

  • 2-ply pouches or double blister packs
  • Packaging in cardboard or polypropylene boxes
  • Custom packaging

ADDITIVE MANUFACTURING

A SPECIALIST IN ADDITIVE MANUFACTURING OF MEDICAL DEVICES

We provide a wide variety of engineering, R&D and production services for 3D printed medical devices.

MARLE GROUP has an ISO 13485-2016 certified design office that can assist you in the design and development of your medical implants. Using our numerical simulation analysis tools, we can provide biomechanical validation based on the ASME V&V 40 protocol and the requirements of the new Medical Device Regulation (MDR).

Our team of engineers specialized in biomechanics can assist you in developing your orthopedic implant projects and Class I-III medical devices. By combining both a medical and industrial approach, we can optimize and streamline the design of your products with our proficiency in additive manufacturing processes.

The qualified technologies used in our additive manufacturing production center allow us to produce prototypes, patient-specific custom items and series production using both metal and polymer-based technologies.
