Abstract

A mobile electronic part consisting of: (i) a pre-treated shaped metal part wherein the metal is selected from a group consisting of magnesium, aluminum and alloys of these metals, and (ii) an overmolded composition layer [layer (C), herein after] bonded onto said pre-treated shaped metal part wherein said composition comprises at least one poly(ethersulfone) polymer [(PESU) polymer herein after].

First claim

1 - 15 . (canceled)

16 . A mobile electronic part comprising:
(i) a pre-treated shaped metal part wherein the metal is selected from the group consisting of magnesium, aluminium, and alloys of these metals; and (ii) an overmolded composition layer (C), bonded onto the pre-treated shaped metal part wherein the composition layer (C) comprises at least one poly(ethersulfone) polymer (PESU).

17 . The mobile electronic part according to claim 16 , wherein the (PESU) polymer comprises more than 50% by moles of recurring units (R PESU ) of formula (A):

18 . The mobile electronic part according to claim 16 , wherein the (PESU) polymer has a melt flow rate (MFR) equal to or higher than 20 g/10 min at 380° C. and under a load of 2.16 kg.

19 . The mobile electronic part according to claim 16 , wherein the (PESU) polymer is functionalized by one or more functional groups.

20 . The mobile electronic part according to claim 19 , wherein the functional group is selected from a group consisting of an hydroxyl, a carboxyl of formula —COOA, wherein A is hydrogen or an alkali metal, anhydride, and epoxide group.

21 . The mobile electronic part according to claim 20 , wherein the hydroxyl group is a phenol OH group and the number of phenol OH groups is equal to or more than 10 μeq/g.

22 . The mobile electronic part according to claim 16 , wherein the thickness of the composition layer (C) is of at most 3000 μm.

23 . The mobile electronic part according to claim 16 , wherein the mobile electronic part is selected from a group consisting of fitting parts, snap fit parts, screw bosses parts, mutually moveable parts, functional elements, operating elements, tracking elements, adjustment elements, carrier elements, frame elements, films, in particular speaker films, switches, connectors, cables, housings, any structural part integrated on housings, and any other structural part other than housings as used in a mobile electronic devices.

24 . The mobile electronic part according to claim 16 , wherein the mobile electronic part is further shaped into a finished part having any type of size and shape.

25 . The mobile electronic part according to claim 16 , wherein said mobile electronic part has been anodized.

26 . A method for manufacturing the mobile electronic part according to claim 16 comprising the following steps:
Step 1—pre-treatment of at least part of the surface of a shaped metal part to form the pre-treated shaped metal part; and
Step 2—forming the overmolded composition layer (C) onto the pre-treated shaped metal part by overmolding the composition layer (C) onto the pre-treated shaped metal part by using an overmolding process.

27 . The method according to claim 26 , wherein the overmolding process is selected from the group consisting of injection molding, heat pressing, compression molding, sintering, machining, or combinations thereof.

28 . The method according to claim 26 , which further comprises an anodization treatment step.

29 . A mobile electronic device comprising the mobile electronic part according to claim 16 .

30 . A method for manufacturing a mobile electronic device according to claim 29 , the method including the steps of:
providing as components at least a circuit board, a screen, and a battery; providing at least one mobile electronic part, according to claim 16 ;
assembling at least one of the components with the at least one mobile electronic part, or mounting at least one of the components on the at least one mobile electronic part.
