Lub nkuaj no yog clamped rau hauv pwm thiab cua yog cua tshuab rau nws. Cov huab cua siab ces thawb cov yas tawm mus ua kom pom cov pwm. Thaum cov yas tau txias thiab khov lawm cov pwm tuaj qhib thiab ntu tawm. Tus nqi ntawm cov tshuab molded yog siab tshaj qhov kev txhaj tshuaj - molded qhov chaw, tab sis qis dua cov qhov hloov molded.
Tus txheej txheem txoj cai los ntawm lub tswv yim ntawm glassblowing. Enoch Ferngren thiab William Kopitke ua tus tshuab moulding tshuab thiab muag rau Hartford Empire Company nyob rau hauv 1938. Qhov no yog pib ntawm kev lag luam tshuab molding. Thaum lub sijhawm xyoo 1940 ntau ntau thiab tsawg ntawm cov khoom yog tseem heev tsawg thiab yog li ntawd tshuab molding tsis noj kom txog thaum tom qab. Thaum cov ntau yam thiab cov nqi ntau lawm tau nce tus naj npawb ntawm cov khoom tsim tau tom qab tsis ntev tom qab.
Cov tswv yim tsim khoom tsim nyog los tsim cov khoom siv ua haujlwm khov kho siv cov tshuab cov nplaum no tau tsim thaum ntxov. Vim hais tias khob yog tawg heev, tom qab kev taw qhia ntawm yas, yas raug siv los hloov iav nyob rau hauv qee. Thawj qhov khoom loj ntawm cov hwj yas tau ua hauv Tebchaws Amelikas thaum xyoo 1939.

Rau amorphous hlau, kuj hu ua ntau qhov muag metallic tsom (BMGs), tshuab molding tau nyuam qhuav pom hauv pressures thiab txias piv rau yas tshuab molding.
