TPC Co., Ltd. is a Gyeongsan-based maker of precision steel tubes and tube-formed automotive parts, established in 1998. The company produces electric-resistance-welded precision tubes on its own tube mills, cold-drawn DOM tubes, and finished parts such as fuel filler necks and engine water pipes.
Production combines tube milling, drawing, cutting, CNC bending, welding, brazing and surface treatment, supported by a corporate R&D centre. Roughly half of its tube output feeds its own parts lines, with the rest supplied as cut tubes and DOM tubing.
Drawn-over-mandrel tubes produced by drawing welded tube through a die to adjust diameter and wall thickness, used among others for noise, vibration and harshness parts.
