Abstract
An ABS resin molded part is manufactured by forming a molded part of an ABS resin into which a particulate filler is mixed, eluting butadiene particles from the surface of the molded part by etching, and forming a plating coat on the surface after the etching.
Claims20
A method of manufacturing an ABS resin molded part, comprising the steps of:
- forming a molded part having a thick walled part and a thin walled part adjoining with each other by injection molding of an ABS resin into a mold, the ABS resin comprising butadiene particles and a particulate filler,
- wherein butadiene particles located in the thin walled part have substantially the same shape as butadiene particles located in the thick walled part;
- eluting butadiene particles from a surface of the molded part by etching;
- and
- forming a plating coat on the surface after the etching.
2 more elements
An ABS resin molded part, wherein:
- an ABS resin comprising a particulate filler and butadiene particles is injection molded to form a shape where a thick walled part and a thin walled part adjoin with each other,
- wherein butadiene particles located in the thin walled part have substantially the same shape as butadiene particles located in the thick walled part;
- butadiene particles are eluted from a surface of the injection molded ABS resin by etching;
- and
- a plating coat with a thickness of 10 μm or less is formed on the surface after the etching.
2 more elements
An ABS resin molded part, comprising:
- an injection molded part having a shape where a thick walled part and a thin walled part adjoin with each other and being made of an ABS resin comprising particulate filler and butadiene particles,
- wherein butadiene particles located in the thin walled part have substantially the same shape as butadiene particles located in the thick walled part;
- etching pits formed on a surface of said injection molded part by etching butadiene particles;
- and
- a plating coat formed on the surface of said injection molded part.
2 more elements
An ABS resin molded part, comprising:
- an injection molded part having a shape where a thick walled part and a think walled part adjoin each other,
- the injection molded part being made of an ABS resin into which a particulate filler is mixed;
- etching pits formed on a surface of said injection molded part by etching butadiene particles, wherein etching pits formed on a surface of the thin walled part have substantially the same density as etching pits formed on a surface of the thick walled part;
- and
- a plating coat formed on the surface of said injection molded part.
