Abstract

A method for producing a housing component with shielding from electrical and/or magnetic radiation and with an environmental seal function, is disclosed. A metal housing part is produced by folding a metal sheet. A synthetic shaped part is produced by thermoforming such that the shape of the synthetic shaped part matches the metal housing part. The synthetic shaped part is connected to the metal housing part. A method for producing a high-voltage store, a housing component with shielding from electrical and/or magnetic radiation, and a high-voltage store are also disclosed.

First claim

What is claimed is:

1. A method for producing a housing component with a shielding from electrical and/or magnetic radiation and with an environmental seal function, comprising the acts of:
in a first act, producing a metal housing part by folding a metal sheet;
in a second act which follows the first act, producing a plastic molded part by thermoforming such that the plastic molded part has a shape adapted to the produced metal housing part; and
in a third act which follows the second act, connecting the produced plastic molded part to the produced metal housing part.

2. The method as claimed in claim 1 , wherein the metal housing part has an outer wall and an inner wall and wherein the plastic molded part is connected to the metal housing part such that the plastic molded part is disposed on the inner wall of the metal housing part.

3. The method as claimed in claim 2 , wherein the plastic molded part is a plastic film.

4. The method as claimed in claim 3 , wherein the plastic film has a thickness less than or equal to 1.0 mm.

5. The method as claimed in claim 1 , wherein the plastic molded part is a plastic film.

6. The method as claimed in claim 5 , wherein the plastic film has a thickness less than or equal to 1.0 mm.

7. The method as claimed in claim 1 , wherein the plastic molded part is a thermoplastic material.

8. The method as claimed in claim 7 , wherein the thermoplastic material is polypropylene or polyethylene.

9. The method as claimed in claim 1 , wherein the metal sheet has a thickness greater than or equal to 1.0 mm.

10. The method as claimed in claim 1 , wherein the act of connecting is done by bonding or heat sealing.

11. The method as claimed in claim 1 , wherein the metal housing part has overlapping regions which are joined to each other.

12. The method as claimed in claim 1 , wherein the metal housing part has a plurality of cavities.
