Ebintu bingi ebikolebwa mu kapiira bibumba, era oluvannyuma lw’okubumba, vulcanization okufuna ebintu ebirina ebisaanyizo eby’omubiri, endabika y’ekintu tekirina bulema bunene, naye enkola eya bulijjo ey’okusala tesobola kuddaabiriza ndabika yeetaagibwa y’ekintu, waliwo obuwundo obutono obutasobola kuggyibwawo, okuddaabiriza mu ngalo oba okusuula kireeta kasasiro mungi mu by’enfuna.

Mu kiseera kino, dizayini y'enzimba ya layini y'okusiba ekibumbe y'ekintu kikulu nnyo naddala, engeri y'okukola dizayini y'emimwa, layini y'okujjula n'omukutu oguyitiridde, n'ebirala, tegenda kunnyonnyolwa wano, osobola okutunuulira 'Rubber Mold Design Manual'.

Ekigendererwa ky’ekiwandiiko kino kwe kunnyonnyola okuva ku nkola n’enkola, kubanga ekibumbe kitera okukolebwa tekitera kusobola kukyusa oba kuggyawo kibumba (kasasiro w’ebyenfuna), emirundi mingi okunoonya yinginiya w’ensengekera okukyusa ensengekera oba okukyusa enkola okutuuka ku kuyulika okwangu.

Wano, tekiba kirungi kuddaabiriza nsengekera eno emirundi mingi, kubanga okukyusa ensengekera etera okuzingiramu oba ebiraga bingi eby’omubiri n’eddagala munda bituukiriza ebisaanyizo by’okusiiga ebintu ebikolebwa mu kapiira, awatali kwongera kwogera, butereevu ku kizimbulukusa:

1. Olw’ebbugumu ly’enkola erya waggulu (okutabula, okusaanuusa, okusimba), okuyokya okutono okuva ku (oluusi rheometer etunuulira ekipande ky’ebyafaayo by’okuwunyiriza ML, TS1 n’ebirala ebisooka okutambula n’okukyukakyuka), ekivaamu obuzibu mu kusala.

Ekigonjoola: okwongera ku muwendo gw’amazzi agakulukuta mu nkola y’amazzi aganyogoza aga mixer oba kozesa ekyuma ekibuguma mu kikuta ekinyogovu (bulijjo yoza ekipimo kya kalisiyamu ekya payipu); Ekyuma kisobola okusima ekiwujjo okwongera okutambula kw’amazzi aganyogoza mu kizingulula okukendeeza ku bbugumu (enkola y’okutabula nayo ya mugaso); Okusimba amangu nga bwe kisoboka okukendeeza ku bbugumu okutuuka ku bbugumu erya bulijjo, tekiba kirungi kusiba mu bungi, ekiyinza okwanguyirwa okuleeta ebbugumu ery’omu makkati erya waggulu n’okuleeta okwokya.

2. Okusaasaana kw’ekintu kya kapiira tekyenkanankana, era kizibu okukutula empenda evudde ku kintu eky’omu kitundu ekinene.

Ekigonjoola: Tegeka mu ngeri entuufu ensengeka n’obudde bw’okutuusa ebintu, okusaasaana kw’ebintu n’okusaanuuka bituukana n’ebyetaago by’enkola, era ebirungo ebisaasaanyizibwa mu kapiira bisobola okugattibwa mu ngeri esaanidde mu dizayini y’ensengekera.

3. Ebbugumu lya vulcanization liri waggulu nnyo, ekivaamu empenda ezikutuka.

Ekigonjoola: londa ebbugumu lya vulcanization n’ensengekera y’ebintu ensaamusaamu, tasobola kugoberera busobozi bwa kukola, okwonoona entropy ya kapiira ne diguli ya vulcanization ensengekera y’ekitundu ya njawulo.

4. Empenda ya kapiira eya vulcanized tekwatagana mu buwanvu era ensobi y’emimwa gy’ekikuta nnene.

Ekigonjoolwa: Kyuusa ekibumbe okutuukana n’ebyetaago by’ensobi mu dizayini n’okutuukiriza ebyetaago by’okufulumya.

5. Mooney y'ekintu kya kapiira nnene, ate 'Green strength' y'ekintu kya kapiira nnene.

Ekigonjoola: Kisobola okufuulibwa obuveera, okukendeeza ku buveera, n’okulongoosa amazzi ga kapiira; Enkola eno erowooza ku buzito bwa Mooney n’okwokya kwa Mooney okw’ekirungo.

6. Obukulu bw’ekintu kya kapiira bubi.

Ekigonjoola: Bw’oba ​​okola dizayini y’ensengekera, lowooza ku buziba, ssaako ebirungo ebikulukuta, ebisaasaanya, ebigonza n’ebizigo, n’ebirala, okulongoosa amazzi g’ekintu kya kapiira, naye okugatta okutwalira awamu kulina okutuukiriza ebipimo by’okukola dizayini y’ebintu n’ebyetaago by’enkola y’okufulumya.

7. Empenda ejjula ku kintu kya kapiira eba nnene era tesobola kuyulika.

Ekigonjoola: okwongera ku puleesa y’ekibumbe kya vulcanization; Okukyusa ekikuta okusobola okutuukiriza ebisaanyizo by’okufulumya; Kendeeza ku Mooney (obukaluba) bw'ekirungo, kapiira kabeere ne 'obugonvu' obulungi n'okukulukuta.

8. Enteekateeka y’ensengekera (form design) terimu magezi.

Ekigonjoola: Olw’okuba enkola eno elowoozebwako mu bintu bingi, okutuukiriza ebyetaago by’okufulumya, ebipimo by’okukola dizayini y’ebintu n’omutindo gw’ebisaanyizo, n’ebirala Dizayini ezenjawulo zisobola okusangibwa mu situdiyo yaffe okukola ensengeka ez’omugaso ezitasaasaanya ssente nnyingi era ezitayamba mu kkolero.

9. Ensonga endala: okutereka ebintu mu ngeri etali ntuufu, okulemererwa oba okukuŋŋaanyizibwa kw’ebintu; Ekiseera eky’okwokya eky’okulonda kapiira embisi tekinywevu; Glue y'okutabula tesobola kutuukiriza byetaago bya 'okutabula mu kitundu ky'amazzi'; enkola ya vulcanization; Okukwatagana kwa accelerator; okusaasaanya obunene bw’obutundutundu bw’ekijjuza; Okusaanuuka kwa resin n’ebirala.
