LED-curable adhesive for high-speed assembly
A fast, tack-free, LED-curable adhesive is designed for joining a variety of plastics used in the manufacture of medical products. Applications include reservoirs, tube sets, port fittings, drug-delivery devices, pumps, and heat-sensitive substrates. Visible and UV light-curable Ultra-Red 1120-M-UR adhesives fluoresce bright red under low-intensity 365-nm black light. The bright-red fluorescence contrasts well on plastics that naturally fluoresce blue in color, such as PVC, and assists with visual inspection of the bond-line area. Free of nonreactive solvents, these adhesive materials cure in seconds. Bondable substrates include ABS, CAP, PA, PC, PI, PS, PU, PVC, and SAN.
Staking and joining technologies
Thermal and high-frequency welding equipment
High-frequency (HF) and thermal welding equipment are suitable for the manufacture of an array of medical device applications. Capable of processing a variety of materials--including PVC, PU, EVA, and fabrics--HF technology is used to fabricate disposable blood, feeding, drainage, ostomy, and IV medical bags; pneumatic compression devices for deep-vein thrombosis; and filters for blood bags. Thermal welding is employed in the manufacture of catheters and disposable feeding and IV bags made from PVC-free materials such as PP, PE, and multilayer films. These welding technologies enable the production of single- and multiple-chamber bags, and they also join multiple tubes and a variety of molded ports and components to various films. The company provides equipment with different levels of automation, from fully automatic in-line machines to stand-alone press machines with little or no automation.

Ultrasonic welding of thermoplastics
A 20-, 30-, and 35-kHz ultrasonic system for welding thermoplastics features a freely programmable effective stroke and automatic start activation. Providing high generator output of 1200 to 6000 W, the HiQ evolution offers an effective stroke feature that allows for optimized sonotrode motion, which can save pneumatic energy and time. Upon completion of a weld, the sonotrode retracts just far enough to remove a processed part and load a new one. This feature reduces the consumption of compressed air by up to 80%, depending on the topology of the assembled parts, according to the manufacturer. The system's closed-loop, high-motion-control pneumatic module regulates pneumatic pressure. Based on electronic differential pressure control of the pneumatic cylinder, the module is active along the complete stroke range. The machine's sonotrode-stack exchange system features a quick-release fastener that allows indexed changes of the preset sonotrode stacks without the need for time-consuming adjustments or tools.
