Abstract
The parts are produced by two-component injection molding. Those regions that are to be metallized consist of a first plastic and those regions that are not to be metallized consist of a second plastic. After the entire surface of the parts has been seeded, the seeding is selectively removed with the aid of a solvent in the regions which are not to be metallized. The first plastic is insoluble and the second plastic soluble in the solvent. The selective metallization then takes place by electroless metal deposition and, if appropriate, electrodeposition of metal.
Claims23
A method of producing a three-dimensional, selectively metallized part from electrically insulating material, which comprises the following method steps:
- producing a three-dimensional part by two-component injection molding, the part having at least one first region to be metallized formed of a first plastic and at least one second region that is not to be metallized formed of a second plastic;
- seeding an entire surface of the part;
- selectively removing the seeding in the second region that is not to be metallized aided by a solvent in which the first plastic is at least substantially insoluble and in which the second plastic is at least substantially soluble;
- and
- depositing metal by electroless metal deposition in the first region that is to be metallized.
