Medical Device Enclosures: Housings for diagnostic equipment including X-ray machines, CT scanners, MRI systems, ultrasound scanners and analyzers, as well as enclosures for surgical lights and operating tables. Sheet metal fabrication produces custom-shaped, dimensionally precise shells that protect internal precision components and provide electromagnetic interference shielding.
Brackets and Support Structures: Covers surgical instrument racks, hospital bed frames, stretcher frames and similar components. These structures are engineered with sufficient strength and stability to support equipment or patient body weight, while satisfying strict lightweight requirements.
Internal Structural Components: Includes auxiliary cabinets such as power distribution enclosures, as well as internal connecting parts and load-bearing elements. These thin-sheet components are manufactured via sheet metal processing to achieve their designated shapes and functions, ensuring a rational, stable internal layout for medical devices.
Pipelines and Channels: Used for gas and fluid delivery systems, such as air circuits for ventilators and fluid pipelines for infusion equipment. Sheet metal processing can fabricate pipelines with custom geometries that meet strict medical transmission specifications.
Stainless Steel: Grades including SUS301, SUS304 and austenitic stainless steel. These materials feature excellent corrosion resistance, high strength and easy cleanability, making them ideal for medical devices requiring repeated sterilization, with no corrosion from long-term human contact or exposure to medical chemical environments.
Aluminum Alloy: Grades 6061 and 6063 offer low weight, high strength, corrosion resistance, plus excellent electrical and thermal conductivity. They are widely used in weight-sensitive device enclosures and brackets, while meeting the heat dissipation requirements of certain medical equipment.
Galvanized Steel, Cold-Rolled Steel and Hot-Rolled Steel: These cost-effective materials with excellent processability are suitable for cost-sensitive medical device components that do not demand extreme strength and corrosion resistance.
Cutting Technology: Laser cutting is the most widely adopted precision cutting method, achieving tolerances controlled within ±0.005mm. It supports cutting of various complex-shaped sheet metal parts with smooth cutting edges, reducing subsequent finishing operations.
Bending and Forming: CNC press brakes are used for bending processing, ensuring high precision and quality of finished parts. Bending forming tolerances can be controlled within ±0.1mm, guaranteeing the dimensional accuracy and shape stability of sheet metal components.
Welding Processes: TIG (Tungsten Inert Gas) welding is the commonly adopted welding method. Welding parameters are strictly controlled during processing to minimize welding deformation and internal stress, ensuring the strength and appearance quality of welded joints, while preventing harmful substances generated during welding from affecting medical environments and human health.
Surface Treatment: Processes including wire drawing, polishing, anodizing, sandblasting, laser engraving and electroplating. These surface treatment processes not only improve the aesthetic appearance of sheet metal parts, but also enhance their corrosion resistance and wear resistance, while meeting medical device requirements for surface cleanliness and biocompatibility.
Medical sheet metal processing must strictly comply with relevant industry standards, such as the ISO 13485 Medical Device Quality Management System, to ensure the safety, reliability and precision of components. Strict quality control is implemented for every process: from raw material procurement and incoming inspection, to in-process dimensional testing and surface quality inspection, through final assembly and finished product validation. All links are strictly controlled to ensure product quality meets the requirements of medical devices.
The medical device industry features the characteristics of "high-mix, low-volume" production. Different hospitals and medical institutions have different requirements for the dimensions, shapes and functions of medical devices. Sheet metal processing can carry out customized production according to the specific needs of customers, providing one-stop services from design, prototyping to mass production, to meet the personalized demands of different clients.
