Zida zazikulu zokuumba ndikupanga makina a Hydraulic. Udindo wa makina a Hydraulic Press Plassiction njira yotsatsira ndikugwiritsa ntchito kupanikizika kwa pulasitiki kudzera mu nkhungu, tsegulani nkhungu ndikuchotsa malonda.
Makina oponderezedwa amagwiritsidwa ntchito makamaka pakuumba kwa thermosetive mapulatisti. Kwa a thermoplastics, chifukwa chofunikira kukonzekera zomwe sizinachitike, zimafunikira mosiyanasiyana, kotero kupanga kumakula, kotero kupanga mphamvu kumakhala kotsika, ndipo kugwiritsa ntchito mphamvu ndi kwakukulu. Komanso, zinthu zomwe zimakhala ndi mawonekedwe ovuta komanso kukula kowonjezereka sikungakanikizidwe. Chifukwa chake kuyerekezera kwakukulu kumapita ku jakisoni wachuma kuchuma.
AMakina Otsutsa Makina(akanikizire mwachidule) Kugwiritsidwa ntchito pakuumba ndi makina osindikizira. Kukula kwake kumafotokozedwa m'matumbo, nthawi zambiri, pali 40t ﹑ 630t ﹑ 160t ﹑ 2500 ﹑ 2500 ﹑ 2500 ﹑ 500t ﹑ 200t ﹑ 400t ﹑ 2500 ﹑ 400T ﹑ 200t ﹑ 1600T ﹑ 200t ﹑ 1600T ﹑ Pali matani oposa 1,000 osindikizira ambiri. Zomwe zili mkati mwazovutazo zimaphatikizapo kugwira ntchito yosangalatsa, yolekanitsa, kapena mikwingwirima pokonzanso mtundu wa piston, etc. Magawo ang'onoang'ono amatha kugwiritsa ntchito makina owotchera (osatentha, madzi ozizira okha) popanga ndikuzizira. Gwiritsani ntchito makina otenthetsera okha mapulasitiki, omwe amatha kupulumutsa mphamvu.
Malinga ndi kuchuluka kwa zochita, makina osindikizira akhoza kugawikana m'manja, makina osindikizira okha, komanso makina oyeserera okha. Malinga ndi kuchuluka kwa zigawo zathyathyathya, zitha kugawidwa m'mawu osindikizira awiri ndi angapo.
Makina osindikizira hydraulic ndi makina okakamiza oyendetsedwa ndi kufalitsa hydraulic. Mukamakambirana, pulasitiki imayamba kuwonjezera ku nkhungu yotseguka. Kenako ikani mafuta opanikizika ku silinda yogwira ntchito. Kutsogoleredwa ndi mzati, piston ndi burashi yosunthika ikuyenda pansi (kapena kupita m'mwamba) kuti atseke nkhungu. Pomaliza, mphamvu yomwe imapangidwa ndi makina a hydraulic imafalikira ku nkhungu ndi kuchita pulasitiki.
Pulasitiki mkati mwa nkhungu imasungunuka ndikusintha pansi pa kutentha. Ng'ombe imadzaza ndi kukakamizidwa ndi makina osindikizira a Hydraulic ndipo zotsatira zake zimachitika. Pofuna kuti atulutse chinyezi ndi ena osinthika omwe amapangidwa panthawi yopanga mapulasitiki ndi kuwonetsetsa kuti zinthuzo, ndikofunikira kuchitapo kanthu mpumulo ndikutha. Nthawi yomweyo zimalimbikitsa. Pakadali pano, resin mu pulasitiki ikupitilira kugwiritsa ntchito mankhwala. Pakapita nthawi, dziko lokhazikika komanso lofooka limapangidwa, ndipo kuumba kumalizidwa. Mvula imatsegulidwa nthawi yomweyo, ndipo chinthucho chimachotsedwa mu nkhungu. Mvula ikatsukidwa, kuzungulira kozungulira kumatha kupitilira.
Itha kuwoneka kuchokera pamwambapa kuti kutentha, kupanikizika, komanso nthawi ndizofunikira pakupanga kusokoneza. Pofuna kukonza zokolola zamakina ndi chitetezo komanso kudalirika kwa opareshoni, kuthamanga kwa makinawo ndi chinthu chofunikira kwambiri chomwe sichinganyalanyazidwe. Chifukwa chake, makina osindikizira a pulasitiki omwe amagwiritsidwa ntchito pokonzekera ayenera kukwaniritsa zofunikira zotsatirazi:
Kukakamizidwa kumayenera kukhala kokwanira ndikusintha, ndipo kumafunikiranso kufikira ndikumakhala ndi kukakamizidwa kwa nthawi yayitali.
② Kubala kwamphamvu kwa hydraulic kumatha kuyima ndikubwerera nthawi iliyonse mu sitiroko. Izi ndizofunikira pokhazikitsa nkhungu, kukanikiza zisanachitike, kungobwezeretsa, kapena kulephera.
③ Kubala kwamphamvu kwa Hydraulic kumatha kuwongolera kuthamanga ndikugwiritsa ntchito kukakamiza kulikonse komwe ku Stroke. Kukwaniritsa zofunikira zamitsempha yosiyanasiyana.
Mtengo wosinthira wa hydraulic uyenera kukhala ndi liwiro lofulumira kuthyoka chiwonetsero chaimuna chisanafike pulasitiki, kuti muchepetse kuchuluka kwa makinawo ndikupewa kuchepetsa pulasitiki. Pamene nkhungu yamphongo imagwira pulasitiki, liwiro lotseka limayenera kuchepetsedwa. Kupanda kutero, nkhungu kapena kuyikapo ikhoza kuwonongeka kapena ufa akhoza kutsukidwa kuchokera ku nkhungu yachikazi. Nthawi yomweyo, kuchepetsa kuthamanga kumatha kuchotsanso mpweya mu nkhungu.
