Plasma pen technology is revolutionizing adhesion in medical device manufacturing by offering a targeted, efficient, and cost-effective method of improving surface bonding. These devices ionize gases at atmospheric pressure, generating plasma plumes used to treat specific areas of polymers, metals, ceramics, and glass. By altering surface properties without affecting base materials, plasma pens enhance adhesion and bonding strength—often up to 50 times greater—without the need for solvents or aggressive chemicals.
Used in applications ranging from catheter assembly to implantable device encapsulation, plasma pens clean, activate, and functionalize surfaces to enable stronger, more reliable joins. This is critical for ensuring performance, fluid compatibility, and regulatory compliance in high-precision environments. Plasma treatment increases surface energy and wettability, allowing adhesives and coatings to spread evenly, minimizing air gaps and improving bond integrity.
Blown plasma and corona discharge are the two common types of plasma used. Blown plasma systems, like PVA TePla’s PlasmaPen, are ideal for larger areas and sensitive materials due to their electrically neutral plumes. Corona discharge pens are more suitable for small, tough-to-reach areas but are less compatible with delicate substrates due to their electrical output.
Plasma pens are well-suited for inline production and cleanroom environments, offering flexibility for prototyping and low-to-medium volume production. They can be integrated with robotic systems and customized for angle, dwell time, and plume control. Cooling features and tip variations reduce thermal damage, enabling safe treatment of delicate components.
For medical device manufacturers facing adhesion challenges or working with complex, multi-material assemblies, plasma pens provide an affordable and adaptable solution. Their implementation enhances bond strength, reduces failure rates, and meets the stringent cleanliness standards required in medical manufacturing.
