In extrusion line manufacturing, every detail matters — especially the vacuum tank, the “sealed heart” that ensures stable pipe forming performance.

With automated and high-precision welding processes, we are reducing human variability, improving consistency, and raising the quality standards of tank manufacturing.

Why robotic welding makes the difference:
✅ Consistent & Strong Weld Seams
Robotic welding stations ensure uniform weld quality across every seam, delivering stronger structures and longer service life.

✅ Higher Production Efficiency
Continuous automated operation significantly reduces welding time and improves manufacturing efficiency.

✅ Stable & Controllable Quality
Supported by professional welding engineers and strict process inspection, every tank is manufactured according to drawings and technical standards.

Technology upgrades are not only about automation — they are about delivering better quality, higher reliability, and greater value for our customers. LIANSU Machinery continues to invest in advanced manufacturing technologies to build high-performance extrusion equipment for global customers.
