End-Forming For Metal Tube & Wire

Precision End Forming for Tubing & Wire Components

Component Supply provides precision end-forming services for hypodermic tubing, stainless steel wire, Nitinol wire, PTFE coated wire, and other specialty metal components used in medical device, research, and industrial applications. Our end-forming capabilities help engineers achieve specific penetration characteristics, assembly requirements, fluid flow performance, and atraumatic device profiles while maintaining tight dimensional tolerances and consistent feature quality.

Component Supply supports precision end forming for:

• 304 stainless steel hypodermic tubing
• 316 stainless steel hypodermic tubing
• 304 stainless steel wire
• 316 stainless steel wire
• Nitinol wire
• PTFE coated wire
• Specialty alloy wire and tubing

For cannulas and hypodermic tubing, the proximal end is commonly produced with a blunt or square-cut finish, while the distal end can be customized into a wide variety of tip geometries depending on the intended application and performance requirements.

Available tubing tip configurations include:

• Chamfer tips
• Bevel tips (bias cut)
• Back bevels
• Lancet points
• Pencil points
• Deflected points
• Anti-coring (Huber) points
• Closed-end configurations
• Franseen tips
• Trephine cuts

For wire and mandrel applications, Component Supply offers a range of precision end-forming and grinding configurations designed to improve assembly, insertion, safety, and handling performance.

Available wire end forms include:

• Bull nose or full radius ends
• Chamfered ends
• Beveled ends
• Conical grinding
• Point grinding
• Aggressive deburring
• Broken edge configurations

Precision end forming is commonly used in:

• Needle and cannula manufacturing
• Catheter assembly
• Guidewire and mandrel fabrication
• Tissue penetration applications
• Septum penetration systems
• Fluid dispensing assemblies
• Minimally invasive surgical devices
• Medical device prototype development

Component Supply works closely with engineers to determine appropriate tip geometries, edge conditions, transition lengths, and surface finishes based on penetration force requirements, material selection, patient safety considerations, manufacturability, and downstream assembly needs.

In addition to end forming, components can be further customized through cutting, bending, EDM machining, OD grinding, welding, passivation, coating coordination, and additional secondary fabrication services to support complete prototype and production-ready assemblies.
