Izinto Ezihlanu Eziqakathekileko Okufanele Uzicabangele Ngaphambi Kokuthenga Umtjhini Omncani Wokwenza Ukutjhisa

Izinto Ezihlanu Eziqakathekileko Okufanele Uzicabangele Ngaphambi Kokuthenga Umtjhini Omncani Wokwenza Ukutjhisa

Imitjhini emincani yokwenza i-thermoform sele zikhethwe khulu emabhizinisini amanengi ngebanga lokuthi zinendawo encani, ukusebenza kwazo kutjhuguluka, ukusetjenziswa kwamandla okuncani, nokusetjenziswa kwazo okuhlukahlukeneko. Kodwana, ukukhetha umtjhini ohlangabezana neemfuneko ezithileko hlangana nemitjhini ehlukileko etholakala emakethe akusimsebenzi olula. Ukukhetha okungakalungi kungadosela ekutheni kube nokukhiqiza okungazinzileko, ukusetjenziswa kwamandla okuphezulu, ukubunjwa okubuthakathaka, nofana ukunciphisa isikhathi sokuphila kwesikhunta. Iindaba ezinjalo azikhuphuli iindleko kwaphela kodwana ziphazamisa isikhathi sephrojekthi.

I. Hlathulula umnqopho nokuhambisana kwezinto

Nanyana yoke imitjhini emincani yokwenza i-thermoforming iwela ngaphasi kwemitjhini yokwenza i-thermoplastic, iindlela zayo zokufuthumala, izakhiwo zokwakha, amahlelo wokuhlanza, kanye nezinto ezihambisanako ziyahluka khulu. Ngalokho-ke, ngaphambi kokukhetha, hlathulula ngokucacileko umnqopho ohlosiweko, kufaka hlangana:

1. Imihlobo yezinto ezihlosiweko

Amaplastiki womtjhiso ajayelekileko afaka hlangana:

I-PP (Polypropylene): Isetjenziselwa kanengi ukuphakheja ukudla iinkomitjhana kanye neentja ezilahlwako, ezitlhoga amazinga womtjhiso aphezulu;

I-PS (Polystyrene): Ibanga elibanzi lokufuthumala elisebenza kuhle;

I-PET/PETG: Ukukhanya okuphezulu okufuna ukulawulwa okuqinileko kwamazinga womtjhiso;

I-PVC: Izokonga kodwana iyasebenza, kodwana ineemfuneko ezithileko zeendlela zokufuthumala kanye nokuhlanzwa kwegesi;

I-ABS: Itlhoga amandla wokufuthumala athuthukisiweko kanye neenhlelo zokugandeleleka;

Iinsetjenziswa ezibolako (i-PLA, ukwakheka kwe-PBAT): Ifuna ukulawulwa kwamazinga womtjhiso okufanako nokuqondileko.

Ukutjhuguluka okukhulu kukhona emazingeni womtjhiso wokuthambisa wezinto ezihlukahlukeneko. Iinhlelo zokufuthumala ezingafaniko zingabangela imiraro efana nokugwedla okungalingani, ukunwebeka okungazinzileko, nokubunjwa okungakapheleli. Ngalokho-ke, ngaphambi kokuthenga, kuqakathekile ukukhomba izinto eziqakathekileko ezizokusetjenzwa begodu uqinisekise bona i-Small Thermoforming Machine isekela izinga lokutjhisa elitlhogekako, isakhiwo se-vacuum, nendlela yokupholisa.

2. Ijometri yomkhiqizo kanye nokubunjwa okuyinkimbinkimbi

Imikhiqizo elula efana nethreyi nofana efana namashidi ineemfuneko eziphasi zokubumba, lokha iinkomitjhana ezinomgodi ojulileko kanye neengcenye zesakhiwo eziyinkimbinkimbi zifuna ukunemba okuphezulu.

Ukuzwisisa i-geometry yomkhiqizo kusiza ekuhloleni ngaphambilini bona imitjhini ihlangabezana na neendingo ezithileko.

II. Ukuzinza kwehlelo lokufuthumala

Ummongo wokwenza i-thermoforming ulele erherhweni lokufuthumala nendlela yokufuthumala:

Ukutjhisa ngeshubhu ye-quartz: Ibizo eliphasi kodwana ukutjhisa okuphezulu ngokunemba kokulawula amazinga womtjhiso okumbi;

Amapuleti wokufuthumala we-ceramic: Ukusebenza kuhle kokutjhisa okuphezulu ngokufana okuhle khulu kobujamo bokutjhisa;
Ama-heater we-infrared akude: Ukufuthumala okurhabako nokusebenza okuphendulako, okufanele izinto ezikhanya khulu;
Iinhlelo zokufuthumala ngepleyidi ye-aluminiyamu: Zijayelekileko eensetjenzisweni ezisezingeni eliphezulu, ezinikela ngokulawula amazinga womtjhiso okuqondileko nokuqina okukhethekileko.
Ukukhiqiza amashidi akhanyako (isib., i-PET), beka phambili amapuleti wokufuthumala we-infrared akude nofana we-ceramic ngombana aqinisekisa ukutjhisa okufanako, ukwehlisa inkungu emhlophe nofana ukutjhisa okukhulu okusendaweni.

III. Irherho lokubumba

Imitjhini emincani yokwenza i-thermoforming ikakhulukazi isebenzela ukukhiqiza okuncani nofana eendaweni zelabhorethri, lapho ukuhlukahluka komkhiqizo nokutjhugululwa njalo kujayelekile. Ngalokho-ke, ukuklanywa okuzwakalako kwehlelo lokubumba kuqakatheke khulu.

Isakhiwo esiqinileko sokubamba isikhunta sinciphisa khulu isikhathi sokutjhuguluka ngesikhathi siqinisekisa iindawo zokwakha ezizinzileko ngaphandle kokungalungi.

Ubukhulu be-mold kungenzeka bungatjhuguluki emamodelini ahlukileko womtjhini wokwenza i-thermoforming. Nawukhiqiza imikhiqizo eminengi, khetha imitjhini enesayizi yepulatifomu yokubumba ejwayelekileko nokuhambisana okuphezulu ukunciphisa iindleko zokubumba ezilandelako.

Njengombana iimfuneko zomkhiqizo zikhula, izinto ezinengi zitlhoga ukugcina amazinga womtjhiso wesikhunta ngaphakathi kwamabanga athileko. Irherho lokulawula amazinga womtjhiso wesikhunta eliqondileko liqinisekisa bona iindawo ezibunjiweko zibuthakathaka nokuzinza kwemilinganiso.

IV. Izinga lokuzenzakalela

Ngitjho imitjhini encani yokwenza i-thermoform, ukuhlakanipha kwezinto ezizenzakalelako kunomthelela ngqo ekusebenzeni kuhle kokukhiqiza, iindleko zabasebenzi, kanye namava wokusebenza.

Imitjhini ezenzakalelako: Efaka ukudla okuzenzakalelayo, ukutjhisa, ukwakha, ukusika, nokupakisha, okufanele ukukhiqiza okuzinzileko.

V. Isevisi yangemuva kokuthengisa

Ukusebenza kwemitjhini akuvezi kwaphela ekucacisweni kodwana nasekuzinzeni kokusebenza kwesikhathi eside kanye neendleko zokulondoloza. Ngaphambi kokuthenga, tjheja khulu izinto ezilandelako:

Imitjhini yokwenza umtjhiso ziinsetjenziswa zobuchwepheshe, begodu iindaba zokusebenza azibaleki. Ukulibaziseka kokuphendula ngemva kokuthengisa kuzokuthinta ngqo amashejuli wokukhiqiza.

Inani lamambala lemali alikho endleleni etjhiphileko, kodwana emtjhinini 'ohlala uletha inani, onciphisa ukuguga nokudabuka, begodu ufinyelela ukusebenza kuhle okukhulu'.
