描述

The plastic SAM card cover is manufactured by the injection molding process. The dried plastic raw material is added to the barrel of the injection molding machine and heated to a molten state. The injection molding machine injects the molten plastic material into the mold cavity through a screw. Under the action of the cooling system of the mold, the plastic material cools and solidifies rapidly to form the initial shape of the SAM card cover. Then, surface treatments such as deburring, silk screening, or pad printing are carried out.
