Tube in consumer goods

Metal tube in household products has to look good, be safe to touch and cost little. The most common need is a closed tube end without a plastic plug (falls out, yellows) and without welding (needs grinding). TONG DA closing machines roll-spin the end at room temperature into a smooth dome or flat end ready for plating or coating.

Buy or subcontract

Consumer products change style often. TONG DA builds the machines and also runs them: high-volume fixed designs buy a machine, mixed small lots subcontract first.

How to start

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