8.FAQ

Kaihua’s plastic chair mold with gas assistant technology redefines chair manufacturing by addressing core pain points of traditional molds. Tailored for PP, ABS, and HIPS materials commonly used in plastic chairs, this mold integrates advanced gas-assisted injection technology to eliminate sink marks, shrinkage, and internal stress—common flaws in thick-walled areas like chair backs, armrests, and leg connections. The optimized gas channel design ensures uniform melt filling, creating chairs with smooth, blemish-free surfaces that meet high aesthetic standards, while the hollowed internal structure (enabled by gas assistance) reduces material usage without compromising load-bearing capacity or structural stability.
Backed by Kaihua’s precision engineering, the mold features CNC-machined cavities with wear-resistant mold steel, ensuring long service life for mass production. It supports customization for diverse chair types—from office chairs and dining chairs to outdoor leisure chairs—adapting gas injection parameters and mold structures to match specific design requirements (e.g., curved armrests, ergonomic backrests). With intelligent process monitoring and standardized components, the mold streamlines production, reduces scrap rates, and shortens lead times, making it an ideal choice for home furniture and commercial seating brands. Plus, the eco-friendly design aligns with green manufacturing trends, minimizing material waste while delivering high-performance plastic chairs.
