تحديد المواقع ختم المعادن الدقة :
تشكل مكوناتنا المعدنية عالية القوة، بما في ذلك علبة نفخ HTD، العمود الفقري الهيكلي لوحدات الوسائد الهوائية في السيارات. يتم تصنيع هذه الأجزاء من سبائك متخصصة، وتعمل كوعاء أساسي لاحتواء الضغط العالي، وتم تصميمها لتحمل الحرارة الشديدة والقوى النبضية اللحظية. من خلال استخدام عمليات التشكيل المتقدمة، فإننا نضمن الختم الموثوق والسلامة الهيكلية تحت الإكراه. وتضمن هذه المكونات توجيه قوى نشر المتفجرات بدقة إلى الوسادة، مما يوفر حاجز الأمان النهائي لحماية الركاب في اللحظات الحرجة.
