Dip & Spray coating

Dip coating is a cost-effective method for coating medical devices, allowing for simultaneous treatment of multiple components. However, it faces challenges in achieving uniform thickness on complex shapes, which can affect reproducibility. A significant drawback of dip coating is the potential formation of bubbles in the coating, which can compromise the integrity and effectiveness of the protective layer. In contrast, spray coating offers better control over thickness and coverage, especially for intricate designs and hard-to-reach areas. It also typically avoids the bubble formation issue seen in dip coating. While spray coating provides more precise application, it often requires more specialized equipment, potentially increasing costs for large-scale production. The choice between these methods depends on the specific device requirements, production scale, and the need for bubble-free, uniform coatings.
