AdvanTech medical/dental injection molding is the optimal choice for efficient, cost-effective, FDA-compliant devices and components.

Considerations for Medical/Dental Injection Molding

Designed as flexible membranes, metal diaphragms are used to create seals in systems — such as fluid control systems — to isolate different enclosures.

Pressure sensor isolation is one of the most common applications; extremely flexible, metal diaphragms allow for the transfer of pressure effects from the process system to a closed pressure sensor system while simultaneously providing protection from the process fluid and protecting the process fluid from contamination.

Choosing the Right Material

  • Strength: Plastic resins are durable and malleable, but each varies in its combination of those qualities. It is critical to select a resin that meets specific medical-grade standards of rigidity and endurance.
  • FDA Requirements: FDA regulations differ for internal and external applications. For instance, internal devices like stents call for certain materials. Selecting the proper resin ensures compliance with these regulations and proper unit performance.
  • Chemical and Heat Resistance: All finished components are exposed to chemicals and heat, especially those subject to sterilization via gamma ray, chemical, or autoclave procedures. Their viability depends on their resistance to these exposures.
  • Operational Compatibility: Finished components need not be subject to extreme sterilization procedures to suffer operational degradation. Be sure to select a resin that will hold up under whatever corrosive, chemical, or radioactive conditions may be present.
  • Life Span and Disposability: Some components are meant to last for many years, while others are designed for disposal, usually after a single use. Cost-efficiency, as well as FDA compliance, requires different materials for these various applications.

Choosing The Right Production Process

Right Production Process

As with any manufacturing process, injection molding projects depend on careful consideration of spatial, dimensional, and economic factors including:

  1. Individual finished unit size and dimension
  2. Part design and geometry
  3. Mold material
  4. Estimated production run quantity
  5. Production cost-effectiveness

The Medical/Dental Injection Molding Process

Plastic medical device

Having selected the proper material/resin, the molding operator executes the following series of procedures:

  1. The selected resin is fed into a barrel, heated and melted by heater bands and friction of a reciprocating screw.
  2. Once the resin is melted, the screw directs it down the barrel toward an injection nozzle.
  3. The nozzle injects the pressurized resin at a high pressure and, calibrated speeds into a steel or aluminum mold.
  4. The injected resin cools to the shape of the mold and is ejected.
