Nhanganyaya
ABS (Acrylonitrile Butadiene Styrene) ndeimwe yeanonyanyozivikanwa thermoplastics anoshandiswa mukuumba jekiseni. Iyo inozivikanwa nekusimba kwayo, kuoma, uye kuita zvakasiyana-siyana, ichiita kuti ive yakakodzera zvikamu zvemotokari, zvemagetsi zvevatengi, uye maindasitiri ekushandisa. Nekudaro, senge chero chinhu, ABS inouya neyayo seti yezvinetso panguva yekuumbwa kwejekiseni. Kunzwisisa nyaya idzi-uye magadzirisirwo azvo-kunogona kubatsira vagadziri kuvandudza mashandiro, kuderedza zvikanganiso, uye kuve nechokwadi chemhando yakafanana.
Warping uye Shrinkage
Imwe yematambudziko akajairika muABS jekiseni kuumba ndeye warping kana kusaenzana shrinkage. Izvi zvinoitika kana nzvimbo dzakasiyana dzechikamu ichitonhorera pamitengo yakasiyana, zvichitungamira kune kusarongeka kwedimensional.
Solution: Shandisa yakakodzera mold dhizaini ine yunifomu yemadziro ukobvu, gadzirisa kutonhora mitengo, uye optimize mold tembiricha. Kudzorwa kurongedza kudzvanywa kunobatsirawo kuderedza shrinkage uye kuve nechokwadi kugadzikana kwedimensional.
Surface Defects
Zvikamu zveABS zvinowanzosarudzwa kuti zvipere zvakatsetseka, asi nyaya dzepamusoro senge sink mamaki, mitsetse yeweld, kana mitsetse yekuyerera inogona kukanganisa kutaridzika uye kuita.
Solution: Kuti uderedze hurema hwepamusoro, chengetedza tembiricha yakanyungudika, chengetedza kuiswa kwegedhi kwakaringana, uye shandisa kupukuta mold kana zvichidikanwa. Vacuum venting inogonawo kubvisa mweya wakavharirwa unokonzera mavanga.
Unyoro Sensitivity
ABS is hygroscopic, zvinoreva kuti inotora hunyoro kubva mumhepo. Kana isina kuomeswa zvakanaka isati yaumbwa, hunyoro hunogona kukonzera mabhuru, splay, kana kusasimba kwemagetsi.
Solution: Nguva dzose pre-dry ABS resin pane inokurudzirwa tembiricha (kazhinji 80-90 ° C kwemaawa 2-4) isati yagadziriswa. Shandisa midziyo yakavharwa kuchengetedza resin kudzivirira kunyura kwemwando.
High Mold Temperature Sensitivity
ABS inoda kudzora tembiricha chaiyo. Kana iyo mold kana mbiya tembiricha yakawandisa, inogona kutungamira mukuderera uye kushanduka. Kana yakanyanya kuderera, inogona kukonzera kusakwana kuzadza kana kusanamatira zvakanaka.
Solution: Chengetedza tembiricha yekuumbwa yakagadzikana mukati meiyo yakakurudzirwa kugadzirisa hwindo. Otomatiki ekutarisa masisitimu anogona kuve nechokwadi chekuenderana panguva yekugadzira.
Dimensional Kururama
Nekuti ABS inoshandiswa zvakanyanya kune zvikamu zvinoda kushivirira kwakasimba, kuchengetedza kurongeka kwedimensional kunogona kuve kwakaoma. Kusiyana kwekumanikidzwa, tembiricha, kana kuyerera kwezvinhu zvinogona kutungamirira kune kunze-kwe-spec zvikamu.
Solution: Shandisa nzira dzesainzi dzekuumba dzakadai secavity pressure monitoring, uye ona kuti mold tooling inochengetwa zvakanaka. Shandisa CAE (injiniya-inobatsirwa nekombuta) simulation panguva yekugadzira kufanotaura zvingangoita shrinkage.
Environmental Stress Cracking
ABS inogona kuve nehanya kune mamwe makemikari, oiri, kana kuenderera kushushikana, zvichitungamira mukutsemuka nekufamba kwenguva.
Solution: Shandura dhizaini yechikamu kuti uderedze kushushikana, shandisa ABS inosanganiswa nepamusoro kuramba, uye ive nechokwadi chekuenderana neyakagadzirirwa nharaunda.
Mhedziso
ABS jekiseni molding inopa yakanakisa mikana yekugadzira yakasimba, inochinja-chinja zvikamu, asi zvinonetsa senge warping, kunyura hunyoro, uye hurema hwepamusoro hunofanirwa kutariswa nemazvo. Nekutora maitiro akanakisa akadai sekugadzirira kwakaringana zvinhu, dhizaini yakagadziridzwa mold, uye kunyatso kudzora tembiricha, vagadziri vanogona kukunda nyaya idzi uye kuwana yepamusoro-mhando, inowirirana mhedzisiro.
