What consumer tubing needs
Chair and table legs, stroller frames, motorcycle racks and coat stands need a clean look, no sharp edges and fast assembly. Typical operations are end closing (replacing plastic plugs and welded caps), grooving and beading (locating rings, retention), shrinking (tube-in-tube joints), notching (tube-to-tube welding) and punching or flattening.

Buy or subcontract
TONG DA is both machine builder and contract processor. Fixed-design, high-volume customers usually buy; mixed-lot or new-product customers often subcontract first and buy once the market is proven.
