Upgraded Manufacturing Process for Silent Plastic Cushioning Components
Jul 02,2026
A new manufacturing process for composite elastic plastic bumpers has been implemented, significantly reducing noise during push-pull opening and closing.
Silent plastic anti-collision buffer parts for sliding windows upgrade with dual-layer elastic injection technology for stile rubber, vertical stile buffers and top-bottom track wind rubber, eliminating harsh impact noise during sliding. Single-layer traditional plastic has fixed hardness causing loud collision sound. New dual-layer parts integrate soft silent outer plastic and rigid support inner plastic to absorb impact and cut noise over 60%.
Dual-feed mold runners inject two plastic materials simultaneously for seamless integration without delamination after 100,000 sliding cycles. Sound-absorbing additives prevent surface hardening in cold northern winters, while modified POM inner layer keeps shape for lasting wind sealing.
Home decoration buyers pay growing attention to window silence, making silent buffer plastic parts standard for system windows. Automatic dual-layer injection lines deliver bulk precise-size products fitting flat, high and double sliding tracks. Multi-color options of black, dark grey and light grey match various broken bridge aluminum frames for unified appearance and silent performance.
