Pain Points

Ntau tus kws tsim khoom siv tshuab luam tawm cov ntaub ntawv pov thawj braid-structure tsis tau ntsuas cov khoom siv-rau-cov khoom sib txuas. Zoo tib yam braid architecture muab cov khoom sib txawv kiag li thaum ua ke nrog cov hauv paus raj thiab cov hlua khi ntawm cov hlau sib txawv. Stainless-steel braided hypotube muaj lub zog tensile siab tab sis txwv elastic rov qab. Nitinol braid coj zoo superelasticity tsis tau xav tau cov txheej txheem nruj kom tsis txhob thermal-induced cov khoom degradation. L605 cobalt-chromium hlau muab kev ua haujlwm zoo zog ntawm cov khoom siv ntau dua. Cov khoom sib xyaw ua ke tsis sib haum ua rau ntxov ntxov braid hlau tawg, tsis txaus crush kuj los yog degraded yooj nyob rau hauv cov hlab plawv, urinary thiab neuro-endoscopic li. Cov pab pawg OEM feem ntau tsuas yog tsom mus rau sab nraud qhov ntev thiab braid ntom ntom, tsis quav ntsej kev sib cuam tshuam ntawm lub hauv paus-tube alloy thiab cov ntaub qhwv hlau. Qhov no ua rau rov ua cov qauv kev hloov kho dua tshiab, txuas ntxiv cov sijhawm txhim kho thiab nce R & D cov nqi rau percutaneous transluminal coronary angioplasty thiab cov duab qhia kev cuam tshuam cov cuab yeej. Lub hauv paus hypotube tuaj yeem ua laser-txiav nrog cov qauv xws li txuas txuas ntxiv, cuam tshuam kauv thiab radial txiav, nrog qhov tsawg kawg nkaus kerf dav 0.012 hli hauv Ø0.20 hli-20 hli ua ntau yam raws li ISO9001: 2015 thiab ISO13485 raws kev tsim khoom.

Txoj Cai Ua Haujlwm

Braided hypotube tag nrho kev ua tau zoo pib los ntawm kev coj tus cwj pwm ntawm lub hauv paus hypotube substrate thiab interwoven braid wire network.
