Trusted materials for medical innovation

Supplying Precision Metals and Services for Surgical Robotic Part Manufacturers & OEMs 

As surgical robotics continues to revolutionize the medical field, Banner Medical, a division of A. M. Castle & Co. stands at the forefront as a trusted supplier of high-performance metals and advanced processing services for surgical robotic component manufacturers and OEMs. Our extensive inventory, technical expertise, and precision value-added services support the development of robotic surgery parts, medical CNC precision parts, and complex robotic systems used in today’s most advanced operating rooms. 

Metals for Miniaturized Surgical Instruments and End Effectors 

The attachments on robotic arms—known as end effectors—are designed to replicate the functionality of traditional surgical tools such as needle drivers, graspers, scissors, vessel sealers, staplers, and cautery instruments, but at a much smaller and more exacting scale. These critical components demand reliability, repeatability, and biocompatibility.

A. M. Castle & Co. through its various divisions supplies a broad inventory of metals suitable for the manufacture of surgical robotics and instruments, including: 

Aluminum Alloys 

• 6061 T6/T651 Bar & Plate 

• 7075 T6/T651 Bar & Plate 

• Aluminum Square Bar 

Known for high strength-to-weight ratios and corrosion resistance—ideal for housings, arm joints, and support components. 

Stainless Steels 

• 17-4 PH Stainless Bar & Plate 

• 300 Series Stainless Bar & Plate 

• Nitronic 60 Bar 

• 400 Series Stainless Bar 

These alloys offer the toughness and corrosion resistance required for repeated sterilization and use in high-precision surgical tools like suturing devices and clip appliers. 

Carbon Steel 

• ASTM A36 Plate & Bar 

Strong and formable, often used in structural elements and custom enclosures for robotic carts and consoles. 

The Critical Importance of Precision in Medical Applications 

In the medical sector—especially in robotic-assisted surgery—there is no room for error. Even the smallest material inconsistency or dimensional variation can impact device performance, surgical outcomes, or patient safety. That’s why A. M. Castle & Co. brings unmatched precision to every product and service we deliver. 

Why Our Precision Matters: 

• Microscale Components: Surgical robotic tools, such as needle drivers and bipolar instruments, operate on the scale of millimeters. We provide the fine tolerances and tight dimensional accuracy needed for optimal articulation and function. 

• Sterilization-Ready Materials: Our stainless steel and aluminum alloys are engineered to withstand repeated sterilization without corrosion or degradation, supporting long-term reliability in surgical environments. 

• Consistent Material Quality: Our Ultrasonic Testing (UT) and material certifications ensure every batch meets strict specifications for strength, integrity, and consistency. 

• Complex Geometries: Advanced services such as CNC milling, laser cutting, waterjet, and centerless grinding allow us to supply near net shape components ready for assembly or finish machining. 

Precision Services for Surgical Robotics Manufacturing 

Our full suite of value-added services supports OEMs and robotic surgery manufacturers from prototyping to full-scale production: 

• CNC Milling & Saw Cutting – Fast, precise shaping of complex surgical robotic parts. 

• Centerless Grinding, Chamfering & Straightening – Ideal for precision shafts, surgical pins, and end effector components. 

• Laser & Waterjet Cutting – Enables tight-tolerance profiling for intricate parts. 

• Ultrasonic Testing (UT) – Ensures zero defects in mission-critical applications like spine implants and suturing mechanisms. 

Serving the Entire Surgical Robotics Ecosystem 

We supply the metals to the manufacturers, who develop the complete range of surgical robotic components, including: 

• Robot Arm Joints & Motion Sensor Housings 

• Surgeon Console Components 

• Tool Holders, Endoscope Holders & Suturing Devices 

• Patient and Vision Cart Assemblies 

• Clip Appliers, Suction Irrigators, and Monopolar/Bipolar Instruments
