1.Multi-Directional Precision Side Core Pulling
  Engineered with heavy-duty, long-travel side sliders to resolve the demolding challenges of mutually perpendicular internal cavities.Ensures perfectly synchronized and linear core extraction, eliminating internal scuffing or wall distortion.

2.Anti-Corrosion Tool Steel & Mirror Finishing
  Built with premium, heat-treated corrosion-resistant mold steels enhanced with micron-level manual polishing.Resists chemical erosion and acid pitting from PVC gas decomposition under high temperatures, extending tool lifecycles.

3.Micron-Level Shut-Off & Flash-Free Control
  Features micro-precision CNC machining and manual spotting to compress shut-off clearances down to a minimum window.Prevents parting-line flash or step defects, optimizing the burst pressure and sealing reliability of the final pipe fittings.
