Discover G.A.S.
the system that supports the orthopedic technician by transforming the casting process into an accurate, objective, and replicable workflow.
The variable of manual skill
Anyone working in an orthopedic lab knows: traditional casting critically depends on the experience, applied force, and “eye” of the orthopedic technician. The final result is heavily tied to the operator’s hands in that specific moment: a slightly different pressure is enough to alter the cast, requiring major structural modifications later on.
The G.A.S. system supports the technician by eliminating these variables. By wrapping the plaster cast, the system guarantees a uniform and objective pressure that no human hand can consistently replicate.
Gravity Socket: the socket born "right"
The core of the system is its ability to capture the impression under real weight-bearing conditions (gravity). This allows the creation of the Gravity Socket, a socket that respects the patient’s anatomy when standing and walking.
Advantages on the workbench:
Faithful and nearly finished positive mold: The plaster model coming out of the G.A.S. is extremely close to the final functional shape. Hours spent heavily interpreting and modifying the cast are drastically reduced, leaving the technician with only standard finishing and smoothing operations.
Zero fitting stress: The socket doesn’t squeeze and doesn’t create abnormal pressure points, drastically reducing post-fitting modifications with the patient.
A practical help for your technical team
- Delegate safely Casting becomes a standardized technical procedure. Thanks to the ease of use of G.A.S., even a junior technician or a less experienced collaborator can perform an excellent cast. This frees up Senior Orthopedic Technicians, allowing them to focus on the more complex phases of alignment and biomechanics.
- Uniform results Whether you have a single lab or multiple branches, the goal is the same: delivering a perfect prosthesis. G.A.S. acts as a quality “metronome”: every Gravity Socket produced will have the same standard of excellence, regardless of who physically performed the cast.
- Smarter, simpler management The modern laboratory must be efficient and functional. No pressurized water: Unlike other systems on the market, G.A.S. generates a homogeneous thrust using only compressed air. Water will only be needed to wet the plaster bandages, with no need for hydraulic pumps, tanks, or complex drains to manage the machine’s pressure.
Validated by "Progettiamo Autonomia" technicians









G.A.S. is not a prototype; it’s our daily standard. The Progettiamo Autonomia orthopedic network (leader in Italy) uses this system to centralize production and ensure that a prosthesis made in Milan is identical to one made in Palermo. We have transformed artisanal experience into a shared Working Method, which we now make available to your orthopedic workshop.
