What medical tubing needs

Tube in wheelchairs, crutches, walkers, bed rails, shower chairs and rehab equipment touches the user directly: no sharp edges, no plugs that can fall out, no crevices that trap dirt. Aluminum must stay light; stainless must stand up to cleaning. TONG DA closing machines roll-spin the tube end at room temperature into a smooth one-piece closed end with no seam and no weld, ready for plating or powder coating.

Contract processing for medical tubing

Medical device makers often run many models at modest volume; TONG DA processes tube on its own machines, quotes after a sample run, and customers buy a machine once volume justifies it.

How to start

Send the part drawing, tube OD × wall × material and quantity; TONG DA proposes a machine or a contract plan.

TD-31040 Hydraulic 3-Station Tube End Closing Machine (Roll Closing / Spinning)

TD-31040 is TONG DA’s patented hydraulic 3-station tube end closing machine. It cold-forms the open end of a metal tube into a fully closed dome, or a dome with a center hole of specified diameter, by roll spinning. No heating, no welding, no plastic plugs. Tube OD 10–40 mm, wall 0.8–2.0 mm, in carbon steel, stainless steel, copper and aluminum. Three stations cycle in turn, so one operator runs the machine without special skill.
