Magnesium Die Casting Protective Gearbox Cover
Experience superior protection and performance with our lightweight, high-strength gearbox covers made from magnesium die casting. These covers are designed to protect critical internal components from debris, dust, and environmental contaminants by taking advantage of the outstanding properties of magnesium alloy, including a high strength-to-weight ratio, excellent vibration damping, and natural corrosion resistance.
Perfect for automotive transmissions, industrial machinery, robotics, and electric vehicle powertrains, these covers provide durable protection while helping to reduce overall system weight. This reduction improves energy efficiency, enhances dynamic response, and increases payload capacity.
Engineered for Protection & Durability
- Lightweight Shielding: Much lighter than aluminum or steel alternatives, this reduces unsprung mass and enhances overall efficiency.
- Robust Construction: Manufactured using high-pressure die casting, it forms a seamless, one-piece cover with uniform wall thickness and strong structural integrity, designed to withstand impacts and vibrations.
- Corrosion-Resistant: Provides excellent protection against environmental factors, ensuring long-lasting durability and a high-quality finish that requires minimal maintenance.
- Precision Fit: Produced through net-shape casting with exceptional dimensional accuracy, it guarantees a perfect seal and easy integration with your gearbox assembly, reducing the need for additional machining.
Our advanced die casting process is specifically optimized for magnesium, enabling the creation of complex shapes, built-in mounting points, and strategically placed ribs for increased stiffness. The result is a high-quality, low-porosity cover that offers dependable protection and contributes to a quieter, more efficient gearbox operation.
