1. Chikhazikitso cha Kugawa kwa Kulemera kwa Ma Band 4

Chigawo cha kulekerera kwa makulidwe a magulu anayi cha mzere wachitsulo chosapanga dzimbiri wolondola chimaphatikizapo kulekerera kolondola kwa Gulu 1 (± 0.02 mm), kulekerera kokhazikika kwa Gulu 2 (± 0.03 mm), kulekerera kwamalonda kwa Gulu 3 (± 0.05 mm), ndi kulekerera kwa mphero kwa Gulu 4 (± 0.10 mm). Chigawo cha magulu anayi ndicho muyezo wogulira wopanga zida zamankhwala, wopanga zosindikizira molondola, ndi malo ogwirira ntchito ang'onoang'ono omwe amafunikira makulidwe okhazikika kuti apange zinthu zotsika. Gulu la akatswiri a WowStainless limapereka zikalata za chimango cha magulu anayi ndi kutsimikizira kuthekera kwa mphero yozungulira pa gulu lililonse. Kuti mudziwe zambiri za zinthu zomwe zili mu WowStainless ndi kufotokozera kwa kulekerera kwa chinthu chilichonse, onanizinthu zodziwika bwinotsamba.

Kulekerera kolondola kwa Class 1 (± 0.02 mm) ndiye gulu loyamba la kulekerera lomwe gulu logula liyenera kuwunika popanga zida zachipatala. Kulekerera kwa Class 1 kumathandizira kukana kupanga kwa 0.5% mpaka 1% pa chipangizo chopangira opaleshoni ndi kugwiritsa ntchito chipangizo chopachikidwa. Kulekerera kwa Class 1 kumafuna mphero yapadera yozungulira yozizira yokhala ndi X-ray kapena laser online thickness measure system. Gulu logula liyenera kupempha chitsimikizo cha kuthekera kwa kulekerera kwa Class 1 kuchokera kwa wogulitsayo pamodzi ndi lipoti lolembedwa la kuyeza makulidwe.

Zifukwa zitatu zosankhira gulu lolondola la kulekerera kwa Class 1 ndi njira yachiwiri yotsimikizira yomwe gulu logula liyenera kuwunika. Zifukwa zitatuzi zikuphatikizapo kutsatira malamulo a zida zachipatala (FDA 21 CFR 820 ndi dongosolo la ISO 13485), kusintha kwa zokolola zopangira (kuchepetsa kwa 3% mpaka 5% poyerekeza ndi kulekerera kwa malonda kwa Class 3), komanso kusinthasintha kwa njira yotsatirira (kupondaponda, kujambula kozama, ndi ntchito ya micro-machining). Gulu logula liyenera kufotokoza kulekerera kwa Class 1 pakutsatira malamulo a zida zachipatala komanso cholinga cha zokolola zopangira.

Zifukwa zitatu zosankhira gulu lololera la kalasi 4 ndi njira yachitatu yotsimikizira yomwe gulu logula liyenera kuwunika. Zifukwa zitatuzi zikuphatikizapo kuchepetsa mtengo (15% mpaka 25% kutsika mtengo pa kg poyerekeza ndi kulolera kwa kalasi 1), kuchepetsa nthawi yotsogolera (kuchepa kwa masiku 5 mpaka 10 malinga ndi ndondomeko yachizolowezi ya mphero yozungulira), ndi kupezeka kwa magiredi (magiredi onse okhazikika kuphatikiza 304, 316L, 430, ndi 17-7PH mu gulu lololera la mphero). Gulu logula liyenera kufotokoza kulolera kwa kalasi 4 malinga ndi ntchito yonse yamakampani komanso kugwiritsa ntchito kotsika mtengo.

2. Kuyerekeza kwa Precision Strip vs Cold Rolled General Strip

Chingwe chachitsulo chosapanga dzimbiri cholondola ndi mtundu wololera kwambiri wa chingwe chachitsulo chosapanga dzimbiri chopindidwa ndi mphero yapadera yopindidwa ndi muyeso wa makulidwe amkati. Chingwe cholondola nthawi zambiri chimagwera m'magulu olekerera a Class 1 (± 0.02 mm) mpaka Class 3 (± 0.05 mm). Chingwe chozungulira chozizira nthawi zambiri chimagwera m'magulu olekerera a Class 3 (± 0.05 mm) mpaka Class 4 (± 0.10 mm). Gulu logula liyenera kusiyanitsa chingwe cholondola ndi chingwe chogwiritsira ntchito pazida zachipatala.

ASTM A480 ndi muyezo wa EN 10088 ndi mfundo yachiwiri yotsimikizira yomwe gulu logula zinthu liyenera kufunsa. Muyezo wa ASTM A480 umafotokoza kulekerera kwa muyezo kwa mbale yachitsulo chosapanga dzimbiri yopindika, pepala, ndi mzere. Muyezo wa EN 10088 umafotokoza mtundu wa chitsulo chosapanga dzimbiri cha ku Europe ndi kulekerera kwa miyeso. Gulu logula zinthu liyenera kupempha zikalata zotsatizana ndi miyezo kuchokera kwa wogulitsayo pamodzi ndi chitsimikizo cha gulu lololera.

3. Kuchuluka kwa Kukana Kumakhudzidwa ndi Gulu la Zipangizo Zachipatala

Kuchuluka kwa kukanidwa kwa chipangizo chachipatala ndi gawo lachitatu lotsimikizira lomwe gulu logula liyenera kuwunika. Kulekerera kolondola kwa Gulu 1 (± 0.02 mm) nthawi zambiri kumathandizira kuchuluka kwa kukanidwa kwa kupanga kwa 0.5% mpaka 1% kwa chipangizo chopangira opaleshoni ndi kugwiritsa ntchito chipangizo chopangira opaleshoni. Chida chopangira opaleshoni chimafuna kulekerera kolondola kwa m'mphepete mwa chipangizocho, pamwamba pa chogwirira, ndi cholumikizira cholumikizira. Chida chopangira opaleshoni chimafuna kulekerera kolondola kwa kumaliza kwa pamwamba, kulumikizana kwa minofu, ndi kulondola kwa kuyika mkati mwa thupi.

Kulekerera kwa Class 2 (± 0.03 mm) ndi njira yachinayi yotsimikizira zida zodziwira matenda ndi chipangizo chowunikira. Zipangizo zodziwira matenda nthawi zambiri zimathandizira kuchuluka kwa kukana kwa 1% mpaka 2% pa kusankha kwa gulu lololera. Chipangizo chowunikira nthawi zambiri chimathandizira kuchuluka kwa kukana kwa 1% mpaka 2% pa kulekerera kwa msonkhano wotsekedwa. Kulekerera kwa malonda kwa Class 3 (± 0.05 mm) nthawi zambiri kumathandizira kuchuluka kwa kukana kwa 2% mpaka 5% pa chipangizo chachipatala cha ogula ndi zida za labotale.

Kugawa zida zachipatala ndi FDA ndi EU MDR framework ndi njira yachisanu yotsimikizira yomwe gulu logula liyenera kuwunika. FDA imagawa chipangizo chachipatala mu Gulu I (chiopsezo chochepa, mwachitsanzo, bandeji yosalala, magolovesi oyesera), Gulu II (chiopsezo chapakati, mwachitsanzo, chipangizo chopangira opaleshoni, pampu yolowetsera), ndi Gulu III (chiopsezo chachikulu, mwachitsanzo, pacemaker yolowetsedwa, valavu ya mtima). EU MDR imagawa chipangizo chachipatala mu Gulu I (chiopsezo chochepa), Gulu IIa (chiopsezo chochepa mpaka chapakati), Gulu IIb (chiopsezo chapakati mpaka chapamwamba), ndi Gulu III (chiopsezo chachikulu). Kusankha kwa precision strip ndi tolerance band kuyenera kugwirizana ndi gulu la zida zachipatala malinga ndi FDA ndi EU MDR framework.
