Abstract

A method for manufacturing a faucet body ( 1 ) for a sanitary faucet, having at least the following steps: a) production of the faucet body ( 1 ) in an injection mold, wherein the injection mold at least partially forms a brushed texture ( 3 ) on a surface ( 2 ) of the faucet body ( 1 ); b) coating the faucet body ( 1 ) with at least one first layer ( 4 ) comprising copper; and c) coating the faucet body ( 2 ) with at least one second layer ( 5 ) comprising a nickel-phosphorus alloy. A faucet body of plastic for a sanitary faucet is also proposed.

Claims (13)

1 . A method for manufacturing a faucet body ( 1 ) for a sanitary faucet ( 13 ), comprising at least the steps listed below:

a) producing the faucet body ( 1 ) in an injection mold, wherein the injection mold at least partially forms a brushed texture ( 3 ) on a surface ( 2 ) of the faucet body ( 1 );

b) coating the faucet body ( 1 ) with at least one first layer ( 4 ) comprising copper; and

c) coating the faucet body ( 1 ) with at least one second layer ( 5 ) comprising a nickel-phosphorus alloy.

2 . The method according to claim 1 , wherein the at least one first layer ( 4 ) is produced having a first layer thickness ( 24 ) of 1 μm to 60 μm.

3 . The method according to claim 1 , wherein the brushed texture ( 3 ) is formed by a plurality of grooves ( 7 , 8 ).

4 . The method according to claim 3 , wherein the grooves ( 7 , 8 ) are each formed having an average length ( 9 ) of 5 mm to 200 mm.

5 . The method according to claim 3 , wherein the grooves ( 7 , 8 ) are each formed having a maximum average depth ( 10 ) of 1 mm.

6 . The method according to claim 3 , wherein the grooves ( 7 , 8 ) are each formed having a maximum average width ( 11 ) of 1 mm.

7 . The method according to claim 3 , wherein adjacent grooves ( 7 , 8 ) of the plurality of grooves ( 7 , 8 ) are formed having a maximum average spacing ( 12 ) of 1 mm.

8 . The method according to claim 3 , wherein the brushed texture ( 3 ) is formed having an average of 10 to 1,000 grooves ( 7 , 8 ) per cm 2 .

9 . The method according to claim 1 , wherein the brushed texture ( 3 ) is at least partially formed as a pattern.

10 . The method according to claim 1 , wherein the at least one second layer ( 5 ) is produced having a second layer thickness ( 25 ) of 1 μm to 5 μm.
