A kind of automobile door handle and its electroplating process

Abstract

The invention discloses an automobile door handle and an electroplating process thereof, and relates to the technical field of automobile parts manufacturing. The key points of the technical scheme include the following components in parts by weight: 32-36 parts of polystyrene; 8-12 parts of DOP; 3 parts of calcium carbonate 3-6 parts of nano-alumina; 1.6-1.8 parts of composite stabilizer; 1.2-2.5 parts of carbon black; 1-1.2 parts of zinc borate; 0.6-0.8 parts of modified magnet powder; wherein, the modified magnet The preparation of the powder includes the following steps: step 1, take a block magnet and put it into a pulverizer for crushing, and then screen through a drying net to obtain particles with a particle size of less than 8mm; step 2, put the magnet material with a particle size of less than 8mm into Stir in the reaction kettle, and introduce copper sulfate with a concentration of 72-84g / L, stir evenly, and then lower the temperature to room temperature after baking; step 3, import the particles obtained in step 2 into the grinder for grinding, and obtain the particle size Modified magnetite powder smaller than 6μm. The invention has the effect of obtaining an automobile door handle with high hardness, high strength and convenient electroplating.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, and more specifically relates to an auto door handle and an electroplating process thereof. Background technique [0002] Traditional car door handles are hardware products, which refer to handles made of iron, steel, aluminum and other metals through forging, rolling, cutting and other physical processing. However, handles made of this material are expensive and heavy. At present, most of the door handle products on the market use plastic materials instead of metal, and use decorative plastic materials such as PC, PMMA, ABS, PA, etc. to replace metal materials. However, the existing car door plastic handles have poor mechanical strength and fatigue resistance, low surface hardness, and limited wear resistance, while car door handles are parts that are frequently used in cars and are easily scratched, and are easily scratched after long-term use. scuffed or otherwise worn during...

Problems solved by technology

[0004] However, the surface of the plastic handle is not electroplated, resulting in traces of direct damage to the structure of the plastic handle during bumping, which seriously affects the use effect of the plastic handle and needs to be improved
