Changes outer diameter section by section within one tube. Stretching, extrusion and welding are all available; most often used to taper the distal end down.
Mark the OD of each section and the transition length on the drawing.
Used on catheters that need a slim distal end for access and a heavier proximal end for support. Often run together with tip forming.
Yes. Necking reduces end OD · ID, flaring enlarges it, to fit assemblies.
Diameter changing combined with bonding of different tubes creates the stiffness steps.
Yes. TDS · MSDS come with every specification reply. ISO 10993 biocompatibility data varies by grade and lot, so we confirm it with the factory (Linstant) and reply.
Standard sizes start with small sample lots. MOQ and lead time depend on dimensions, material and secondary processing — send OD · ID · wall · tolerance · length · quantity and we reply within one business day.
Inner diameter, wall thickness, length and operating environment — those four settle the item. We reply with TDS, MSDS and MOQ.
