Alloy Die Casting for Rehabilitation Medical Equipment

　　Rehabilitation medical equipment, including wheelchairs, orthopedic braces, and physical therapy machines, relies on alloy die casting to balance strength, weight, and cost-effectiveness. These devices often require load-bearing components that can withstand repeated use while remaining lightweight to ease patient handling.

　　Zinc alloys (e.g., Zamak 5) are favored for small, intricate parts like wheelchair brake levers or adjustment bolts, offering high dimensional stability and excellent surface finish for subsequent plating (e.g., chrome) to improve aesthetics and corrosion resistance. For larger components such as wheelchair frames or exoskeleton joints, aluminum alloys (e.g., 6061) are preferred due to their higher strength-to-weight ratio. Die casting these parts allows for complex geometries, such as integrated hinges and mounting points, reducing assembly steps and improving structural integrity.

　　The die casting process for rehabilitation equipment must prioritize durability. HPDC ensures dense, defect-free castings that resist fatigue from repeated motion. Post-casting treatments like powder coating provide a protective, non-slip surface, crucial for patient safety. Additionally, components often undergo stress testing to meet standards like ISO 10328, ensuring they can support specified loads without failure. The ability to mass-produce consistent parts via die casting also helps keep rehabilitation equipment affordable, making it accessible to a broader range of users.
