Ultra-thin plastic hardware for minimalist narrow-frame broken bridge aluminum windows enters mass production, including slim stile anti-collision rubber, narrow-groove wind blocks, micro drain covers and small center column injection sheets, solving space limits of sealing, buffering and draining parts for narrow-profile windows. Traditional plastic parts are too thick for profiles under 25mm width, while new slim designs adopt hollow inner structure to cut thickness by 40% while keeping elasticity and support strength.

Multi-layer composite elastic structure of thin anti-collision rubber maintains noise reduction after 100,000 opening-closing cycles without deformation. Micro drain covers shrink flow channels to fit narrow frame drain slots, blocking dust and insects without occupying sealing space. Precision ultra-thin mold cavities control plastic flow speed to avoid thin-wall defects, keeping yield over 98%. Minimalist decoration window market booms with fast-growing orders of narrow French and balcony sliding windows, creating rigid demand for ultra-thin plastic accessories. Processors launch matte multi-color surface treatment to match mainstream grey and black narrow aluminum frames without extra painting. Modified formulas will be optimized to shrink part size further for ultra-narrow frame windows.
