The High Precision Medical Core Mandrel is engineered for demanding applications such as catheter shaft forming, microtube processing, and liner extrusion. Manufactured with an ultra-tight diameter tolerance of ±0.005 mm, it ensures exceptional dimensional consistency, high straightness, and burr-free surface finish, which are essential for precision medical device manufacturing.
Crafted from medical-grade stainless steel or nickel-titanium alloy (optional), each mandrel undergoes electropolishing, ultrasonic cleaning, and deburring processes to meet cleanroom and biocompatibility standards. With customization in length, diameter, surface roughness, and tip geometry, this mandrel supports a wide range of OEM catheter and microtubing production needs.
Ultra-tight diameter tolerance ±0.005 mm
Ra < 0.1 μm electropolished surface for minimal friction
High axial straightness ≤ 0.1 mm per meter
Available in medical-grade 316L stainless steel or Nitinol
Deburred, chamfered or radiused ends for tubing safety
OEM customization supported: size, surface, tip, packaging
Ideal for catheter shaft support, extrusion cores, and balloon forming
