Medical-grade quality requires total precision to support superior health outcomes. Godfrey & Wing’s vacuum impregnation technology ensures this by removing trapped air and moisture to seal porosity with high-quality resin. By resolving these complex challenges, we empower manufacturers to eliminate defects and deliver higher-quality, reliable solutions to the medical market.
Porosity Challenges in Medical Components
Certain medical components, such as 3D printed metal and polymer components, can have material gaps and microvoids that can lead to microleaks and corrosion. Untreated or poorly sealed material surfaces can also absorb traces of contaminants, leading to worsened performance, spreading infections, and costing users high repair and replacement costs.
Some of the porosity challenges that Godfrey & Wing works to solve with vacuum impregnation for medical components include:
- Microvoids and exposed pores in 3D printed components
- Untreated porosity results in air trapped beneath paint and other surface coatings that can cause blisters, roughness, and discoloration
- Vulnerability to chemical degradation in reactive materials
- Internal void channels that can cultivate bacteria and other microorganisms
How Godfrey & Wing’s Vacuum Impregnation Works
While casting and molding processes can create goods that appear reliable, the liquefaction and injection process can leave behind air bubbles and potential leak paths that can lead to efficiency concerns or potential safety risks. It’s especially critical to choose methods like high-quality vacuum impregnation for the medical industry, where equipment needs to work without errors.
At Godfrey & Wing, we have a thorough process for vacuum impregnation. After components undergo cleaning, a vacuum chamber pulls air and moisture out of the pores. A liquid sealant or resin is then added, which fills the pores and microvoids to create an impenetrable seal. Components are then washed to remove excess resin and cured before undergoing testing to ensure each part delivers leak-free performance.
Applications in Medical Device Manufacturing
Vacuum impregnation can be used to meet a range of industry demands for medical device components. Some common applications include:
- Die castings for hardware, surgical tools, and more
- Sintered metal components
- 3D printed medical tools and housings
Vacuum impregnation enhances the sealing and overall functionality of manufactured medical components. This process provides critical benefits such as leak resistance, chemical protection, and long-term performance stability.
