Product Description

 

The OEM Medical Grade Mirror Polished Mandrel Wire is specifically engineered for use in the manufacturing of interventional catheters, guidewires, and precision tubing systems. Made from biocompatible 316L stainless steel, this mandrel wire features an ultra-smooth mirror-finished surface, ensuring minimal friction, easy tube release, and outstanding dimensional control during heat setting, extrusion, and coiling processes.

Manufactured with a tight diameter tolerance of ±0.005 mm and surface roughness Ra ≤ 0.1 μm, this wire is ideal for supporting medical-grade thermoplastics and PTFE liners during fabrication. Each wire is electropolished, deburred, ultrasonically cleaned, and available in fully customizable dimensions, making it suitable for high-end OEM catheter and guidewire production environments.

Key Features

• OEM customized mandrel wire for catheter and guidewire manufacturing

• Mirror polished electropolished surface for frictionless liner release

• 316L medical-grade stainless steel for corrosion resistance and biocompatibility

• Tight tolerance: ±0.005 mm for superior dimensional control
