Tube welding

Tube welding is usually done by heat fusion, where heat is used to partially melt the plastic material, then solidifies under cooling to form a stable weld, thus firmly bonding the tube components together. Medical tube welding is widely used in the manufacturing process of various types of medical catheters, such as intravenous catheters, cardiac catheters, drainage tubes, etc. It can be used to connect the catheter body. It can be used for connecting the catheter body or connecting catheter segments made of different materials.

CM120 Tubing Welding Machine is a tabletop tube welding system that can be used to weld tube components of various sizes and materials. It is specially designed for welding similar polymer material components, such as welding the inner lumen tube to the distal tube body or the proximal and distal necks of the balloon and catheter tube body.


This tube welding machine is easy to operate and integrate into the automated production line. It can handle a variety of medical plastic tubes, such as polyvinyl chloride (PVC), polyester (PET), polyamide (PA), etc., to meet the welding needs of different medical devices.


The equipment uses servo motor and precise temperature to ensure the stability of various parameters during the welding process, so as to obtain a firm and reliable welded joint. It also optimizes the operation interface and fixture design according to the characteristics of medical device manufacturing, improving work efficiency and consistency of welding quality.
