Thermal bonding of plastic extrusions to molded plastic hubs avoids the use of solvents or adhesives while providing a superior strength joint. Polymers must be compatible and suitable for heat bonding. Differences in wall thicknesses between the tube and the hub create unique challenges. Precise external geometric configurations and thermal profiling help assure maximum joint strength. A wide variation in tube sizes, joint designs and polymer choices add extra layers of complexity to the bonding process. Vante and PlasticWeld diverse equipment options provide you with unmatched versatility to meet your specific production challenges.

Many catheters utilize balloons to help stabilize their location after deployment. The balloons must be securely attached to the catheter tube and provide a leak-free seal to assure proper functioning. Thermal bonding of the balloon’s stems to the catheter is possible when both are produced from similar or compatible polymers. Thermal bonding eliminates the use of dangerous solvents or adhesives, and enables profiling the exterior shape of the welded area. A wide variation in tube sizes, balloon configurations and polymer choices add extra layers of complexity to the bonding process. Vante and PlasticWeld diverse equipment options provide you with unmatched versatility to meet your specific production challenges.
