Thaum lub sij hawm molding txheej txheem, qhov tseem ceeb ntawm cov khoom los ntawm contour mus rau cov yeeb nkab yuav ua nkig, thiab kev siv Voss system tuaj yeem txo qhov tsis muaj zog no. Ua ntej, cov nyhuv incision yog minimized los ntawm kev kho mob. Qhov thib ob, SOR txiv ntseej nrog kev sib koom ua ke ntawm lub nplhaib kaw kom nruj cov yeeb nkab radially nyob ib ncig ntawm nws, absorbing dynamic loads sab nraum qhov chaw tseem ceeb, yog li txhim kho nws cov load-bearing muaj peev xwm thiab tawg tsis kam.
Lub Voss yeeb nkab sib koom ua ke yog tsim los thoob plaws hauv lub tebchaws rau kev nyab xeeb, kev ua haujlwm siab, kev ua haujlwm ntev, thiab kev ua haujlwm zoo. Qhov Shengba no kuj yog qhov kev ntsuam xyuas tsim nyog tshaj plaws ntawm ES-4/ES4-VA mos foob pob qij txha. Muab ntau yam zoo los ntawm kev siv technology tshiab. Kev sib xyaw ua ke ntawm cov cuab yeej siv tau zoo dual txiav tshuab thiab ob qhov muag muag muag tsim cov kev daws teeb meem zoo tshaj plaws uas ua tau raws li qhov yuav tsum tau muaj kev kub siab thiab ntxiv kev ruaj ntseg sealing, nrog rau ntau yam kev siv. Txawm tias yuav tsum muaj kev ruaj ntseg ntawm plaub npaug ntawm qhov system siab, ES-4 cov khoom txuas tuaj yeem siv nrog kev ntseeg siab. Lub teeb yuag "" series tuaj yeem tiv taus qhov siab ntawm 500 bar, thaum lub luag haujlwm hnyav "S" tuaj yeem tiv taus qhov siab ntawm 800 bar.
