Material Matching Strategy Rau Coated Hypotube Medical-Grade Production

Pain Point

Coated hypotube kev ua tau zoo nyob ntawm qhov sib piv ntawm cov khoom siv hypotube alloy thiab cov khoom siv txheej txheej. Cov ntaub ntawv hypotube substrate feem ntau npog 304, 316L stainless hlau, 17-7PH, Nitinol thiab L605 cobalt-chromium alloy. Txhua cov khoom siv hlau muaj cov cuab yeej tshwj xeeb saum npoo av, thermal expansion coefficient thiab mechanical feature. Kev sib koom ua ke tsis raug ntawm cov khoom siv substrate alloy thiab txheej txheej ua rau muaj kev pheej hmoo tsis ua haujlwm: qis txheej txheej-substrate adhesion, txheej micro-cracks nyob rau hauv hypotube dabtsi yog khoov-torque cycles, txheej delamination thaum simulated-lub cev-kua dej soaking. Txawm hais tias laser-txiav geometry (nruam muab kauv txiav, cuam tshuam kauv txiav, radial txiav) yog zoo kawg nkaus machined nyob rau hauv Ø0.20 mm-20 mm dimension range nrog tsim nyog 0.012 mm kerf dav, cov khoom tsis zoo txuam tseem ua rau coated hypotube ua tsis tau ISO 13485 kev kuaj xyuas cov khoom pov thawj. Ntau pab pawg tsim tsuas yog xaiv txheej raws li qhov xav tau ntawm qhov chaw ua haujlwm, tsis quav ntsej cov khoom siv txheej txheej txheej. Cov khoom siv-mismatch qhov mob no ua rau cov khoom seem siab hauv coated hypotube manufacturing.

Taw qhia txog Txoj Cai

Material-matching txoj cai rau coated hypotube tsom rau compatibility ntawm hypotube hlau substrate thiab functional txheej.
