Stroller Seat Big Joint
Product Introduction
As a core rotating stressed part, seat joint requires ultra-high structural strength, shaft hole precision, smooth rotation, wear resistance and fatigue reliability. HENGBIN provides full-process mold development including design evaluation, manufacturing, trial and modification.High-strength thick-wall structure with precision core-pulling, multi-directional slides and positioning pins for high-precision demolding of rotating shaft holes, ribs, limit clips and connecting surfaces. Enhanced cooling and packing control shaft hole precision and geometric tolerance, reducing sinks and internal stress. Ensures flexible rotation and reliable strength complying with strict safety, durability and anti-loosening standards.
