Must know the surface treatment method of Collapsible core,Ruibole
The purpose of the surface of the mold is to make the Collapsible core itself have anti-corrosion ability, so as to increase the reliability and adaptability of the mold. Therefore, the quality of the surface treatment of the telescopic core is judged, and the most important thing is to check whether the anti-corrosion ability of the Collapsible core is useful or not, and Whether the added range meets the expected requirements.
1. Electroplating
Mold Collapsible core plating refers to immersing the part of the mold that needs to be electroplated into a specific aqueous solution. The aqueous solution will contain some accumulated metal compounds, so that after the current passes through the aqueous solution, the metal substance in the solution separates and adheres to it. Dip on the part. The electroplating of Collapsible core generally includes zinc, copper, nickel, chromium, copper-nickel alloy, etc.
2. Hot dip galvanized
The hot-dip galvanizing of the Collapsible core is to immerse the telescopic core of carbon steel into a molten zinc plating tank with a heat of about 510℃, so that the iron-zinc alloy on the surface of the mold will be converted into passivated zinc, and then the surface treatment effect will be obtained. .
3. Mechanical plating
The mechanical plating of Collapsible core refers to the use of specific physical and chemical means to impact the surface of the mold with the powder of the coated metal, so that the coated metal is cold welded to form a coating on the surface of the mold to achieve the surface treatment effect. Its mechanical plating is mainly suitable for spare parts such as screws, nuts and washers.
We generally use electroplating, hot-dip galvanizing, and mechanical plating for the Collapsible core surface. The process of forming a covering layer on the surface of the Collapsible core can show a more beautiful appearance after surface treatment. , The anti-corrosion ability of the mold itself will also be improved.
