نموذج: Airbag System
علامة تجارية: HTD
مكان المنشأ: الصين
تحديد موضع المنتج:
تعتبر علبة نفخ HTD هي المكون الأساسي لاحتواء الضغط العالي والمكون الهيكلي داخل نظام الوسادة الهوائية للسيارات. بصفته "حاجز الأمان" لوحدة الوسادة الهوائية، يجب أن يتحمل الحرارة الشديدة والضغط العالي الناتج عن النافخ خلال أجزاء من الثانية، مع ضمان توجيه القوة الانفجارية بدقة ويمكن التحكم فيها إلى وسادة الوسادة الهوائية. باستخدام السبائك/البلاستيك الهندسي عالي القوة وعمليات التشكيل/القولبة الدقيقة، فإنه يحقق التوازن المثالي للسلامة الهيكلية، والختم الموثوق، وإطلاق الضغط الدقيق في الظروف القاسية، مما يجعله عنصر أمان بالغ الأهمية لحماية حياة الركاب.
