Patent Images
1. High-grade plastic product comprising:
- a high-grade plastic component formed of a plastic material and having a particulate material embedded in said plastic material;
a basic body having a positive connection to said high-grade plastic component and including at least one strap-shaped part embedded in said plastic material, wherein said plastic material contracts physically when changing from a fluid state to a solid state, and wherein the positive connection between said basic body and said high-grade plastic component includes said solid plastic material exerting a contracting strain on said at least one strap-shaped part by virtue of said at least one strap-shaped part being embedded in said plastic material while in said fluid state thereof.

Abstract
With a high-grade plastic component, e.g. a plastic-bonded permanent magnet (1; 2), which is fixed to a basic body (4; 5), the basic body (4; 5) shows at least one strap-shaped part (7; 8) for the purpose of fixing it to the plastic component. In order to avoid the plastic component (1; 2) tearing off the basic body (4; 5), the strap-shaped part (7; 8) is surrounded with the high-grade plastic during manufacture of the plastic component and is arranged in the high-grade plastic in such a way that it can take up contraction strains of the high-grade plastic after manufacture of the plastic component at least partly by bending.

-
a high-grade plastic component formed of a plastic material and having a particulate material embedded in said plastic material;
a basic body having a positive connection to said high-grade plastic component and including at least one strap-shaped part embedded in said plastic material, wherein said plastic material contracts physically when changing from a fluid state to a solid state, and wherein the positive connection between said basic body and said high-grade plastic component includes said solid plastic material exerting a contracting strain on said at least one strap-shaped part by virtue of said at least one strap-shaped part being embedded in said plastic material while in said fluid state thereof. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10)
said high-grade plastic component is in the shape of a ring or disc, and the basic body has a longitudinal axis and comprises (i) a bush-shaped part, and (ii) a flange part extending laterally of the bush-shaped part, and said at least one strap-shaped part is arranged at the flange part and is inclined towards the longitudinal axis of the basic body. -
3. High-grade plastic product according to claim 2, comprising a plurality of said strap-shaped parts distributed along a circumference of the flange part.
-
4. High-grade plastic product according to claim 3, wherein
the flange part is in adjoining relationship to the bush-shaped part; -
the flange part includes a ring which is oriented generally radially with respect to the longitudinal axis of the basic body, the ring being provided with openings each having inside and outside radial edges, the strap-shaped parts being arranged at the inside and outside radial edges of said openings, and the opening being filled with the plastic material containing the particulate material embedded therein.
