Yini i-shrinkage ekukhiqizeni isikhunta se-EPS

1
Ngokuvamile, i-shrinkage ye-EPS ngu-0% - 0.3%. Izinga elithile le-shrinkage lihlobene nezimpawu zokwenza izinto ngakunye, izimo zenqubo (ikakhulukazi izinga lokushisa dengwane), ukuqina komkhiqizo nobukhulu. Kwezinye izimo, njengokushisa okuphezulu okulimazayo nomkhiqizo obukhulu, imikhiqizo ye-EPS ayigcini nje ngokuncipha, kepha yandise. Ngakho-ke, ukuguqulwa kwe-shrinkage ye-shrinkage ye-EPS kanye nenqubo yokubumba ejwayelekile kufanele kubhekwe kwinqubo yokukhiqiza yokubamba. Ubukhulu bokubumba kufanele bukhuliswe ngokufanele, ngokuvamile 0.2%

Ngaphezu kwalokho, kufanele kuboniswe ukuthi ngemikhiqizo yokupakisha enobukhulu obungalingani, ingxenye enkulu akulula ukuyipholisa, okuholela ekunwendeni kwasendaweni. Ngakho-ke, lapho kuklama ukufakwa, ubukhulu bodonga kufanele bufane ngangokunokwenzeka, futhi amabhulokhi abunjiwe kufanele angezwe ezindaweni ezikhudlwana
2. Shrinkage deformation of aluminium isikhunta ngesikhathi sokuphonsa
Ukulawula lokhu kuguqulwa kwe-shrinkage kufaka phakathi izinkinga eziningi zobuchwepheshe, ezibhekisela kuMargin of Woodformworkwork.
(1) Ijamo lejometri nobukhulu be-aluminium isikhunta buzothinta i-shrinkage of castings. Ngokuvamile, ukuguqulwa kwe-shrinkage deformation of i-aluminium castrings eningi kukhawulelwe
(2) I-shrinkage yangempela ye-aluminium ngokuvamile i-1.1 - 1.2%
(3) Isibonelelo se-shrinkage sokhuni isikhunta sihlobene nenqubo yaso kanye nezimo zobuchwepheshe, ikakhulukazi izinga lobuchwepheshe lenqubo yokuphonsa. Ngokuvamile, usayizi wesikhunta wezinkuni kudingeka ukhuliswe ngo-1.3 - 1.8%. Indlela ethile inganqunywa ngokuya ngesimo sangempela. Uma indawo yokuphonsa ibushelelezi, izinga lenqubo liphezulu futhi isibonelelo semishini sokubumba sincane, imvume yokuvunyelwa kwezinkuni kufanele futhi kube yincane
(4) Udonga lokubumba kufanele lube mncane futhi ingaphezulu kufanele lube bushelelezi ngangokunokwenzeka. Ngakho-ke, umnyombo wokuphonsa kufanele wenziwe ukuze athuthukise ukunemba nokuqedwa kwezinsizwa zokhuni

Onjiniyela bethu bokubumba banolwazi oluhle nolwazi olucebile ekwenzeni isikhunta, senze isikhunta semishini yaseChina e-EPS, imishini ye-EPS yaseJapan, imishini ye-EPS yaseJapan njll.

Uma ucela imibuzo nge-EPS Mold, wamukelekile ukuxhumana nathi ukuthola eminye imininingwane, ngiyabonga!
