Problems solved by technology

[0003] Existing tantalum capacitor shells are all made of plate deep drawing process. The conventional process is plate blanking, deep drawing, secondary deep drawing, third deep drawing, and finally edge trimming to obtain the shell of tantalum capacitors. This production process is cumbersome to operate, and A lot of waste is generated, and the cost of tantalum metal is relatively expensive, resulting in higher material costs

Description

technical field [0001] The invention relates to the technical field of production and processing of tantalum capacitors, in particular to a tantalum capacitor casing extrusion molding device. Background technique [0002] As we all know, the full name of tantalum capacitor is tantalum electrolytic capacitor, which is also a kind of electrolytic capacitor. Solid tantalum capacitors were first successfully developed in 1956 by Belle Laboratories in the United States. Tantalum capacitors use tantalum metal as the medium, and do not need to use electrolyte like ordinary electrolytic capacitors, nor do they need to be fired with capacitor paper coated with aluminum film. [0003] Existing tantalum capacitor shells are all made of plate deep drawing process. The conventional process is plate blanking, deep drawing, secondary deep drawing, third deep drawing, and finally edge trimming to obtain the shell of tantalum capacitors. This production process is cumbersome to operate, and...
