RF Welding

What is RF welding?

RF welding(Radio frequency welding) is the process of bonding materials together using high frequency electromagnetic energy (radio waves). During welding, high frequency electromagnetic fields generate electrical currents that generate heat in the welding material, bringing it to its melting point. After welding is complete, the welding material cools rapidly to form a strong welded joint.

Due to its high process efficiency and stable welding quality, its often used in medical device manufacturing such as thermoplastic bonding of soft tips on catheter shafts and thermal reflowing of catheter terminations.

What are the advantages of RF-welded catheter tube?

●RF welding of catheter has excellent sealing properties and is reliable and robust.

●Through RF welding, catheter tubing can be butt-welded together.

●RF welding can precisely control the temperature and heating evenly make the catheter quality consistently.

Which materials of catheter is suitable for RF welding?

PVC, PEBAX, PU, LDPE, PP, PA, FEP and other thermoplastic polymers

Which medical catheter components require RF welding?

●Catheter tips: taper/conical, closed end tip, neckdown, tip and end forming, radius tip, angle tip,multi-lumen, soft tip,s heath tip, dilator tip, iv tips, guidewire tip, CVC, urinary, angiographic, tracheal

●Bonds & welds:butt welds, overlap welds, braid to non-braid welds, plastic to metal joining, soft tip, balloon bonding, hub welds, strain reliefs, taper welds, marker band embedding / placement, angiographic, needle guide

●Flares & Flanges: falres, flanges, mushrooms, arrow heads, nailheads, polygon shapes, upset tube/ OD expansion, inside flares

●Eyelets & Holes:polished eye forming, skiving, punched holes, side porting, hot eye forming
