With the rapid upgrading of new energy vehicles, automotive interior parts are moving toward integration, lightweight design and low-emission standards. As the core raw material for in-situ foaming molding, PIP (Pour-in-Place) combined foam material for automotive headrests has become a mainstream solution for high-quality automotive interior production.
Traditional headrest manufacturing adopts separate foaming and fabric wrapping processes, which involves complicated working procedures and commonly causes fabric wrinkling, delamination and displacement after long-term use. In contrast, the PIP one-piece molding process directly injects polyurethane combined foam into pre-sewn fabric covers and realizes integrated foaming and bonding in one step. This technology greatly simplifies production procedures, shortens cycle time and improves surface conformity and overall fullness of finished headrests.
The optimized PIP headrest foam system features stable fluidity and excellent filling performance, which perfectly adapts to irregular and complex headrest cavity structures and effectively reduces overflow risks during production. The finished foam delivers superior resilience and low compression set, meeting professional safety requirements for anti-whiplash protection in rear-end collisions and complying with mainstream automotive interior industry standards. In addition, the upgraded formula realizes low VOC and low aldehyde emission, fully matching the strict low-odor and eco-friendly requirements of new energy vehicle cabins. It is compatible with various fabrics and synthetic leather materials and fits most existing circular PIP production lines and single-station pouring equipment without major modification.
As the penetration rate of high-end new energy vehicles continues to rise, PIP integrated headrests have become increasingly popular in passenger car projects. The continuous iteration of domestic PIP foam materials further promotes independent innovation and high-quality upgrading of the automotive interior supply chain.
