What are the process performance of metal

by:Fortuna     2021-02-08
In life, the hardware has been applied to many places. With the development of the society progress, the application of the hardware more. At present our country many hardware product production first in the world, such as lighters, zippers, wrench, pliers, etc. , are in a foreign country has a good sales record. At the same time, after years of development, the characteristics of hardware industry cluster in China gradually. Then the hardware with the performance, the following by precision compiled by author. Casting performance: refers to whether metal or alloy is suitable for casting of some process performance, mainly including flow performance, full of mold ability; Contractility, casting volume shrinkage during solidification of ability; Segregation refers to the chemical composition of non-uniformity. Welding performance: refers to the metal materials by heat or heat and pressure welding method, the two or more than two metal material welding together, characteristics of the interface can meet the purpose. Aeration top performance: refers to the metal materials can withstand the upsetting and not the performance of the rupture. Cold bending performance: refers to the metal material to withstand bending at room temperature without rupture performance. Bending degree of bending Angle is commonly used in alpha ( Exterior Angle) Or bend the ratio of diameter d on the material thickness of a heart, said a big or d/a small probability, the cold bending property of the material is better. Stamping performance: metal stamping deformation under processing and not burst. At room temperature for stamping called cold stamping. Inspection method is to use a test cup drawing test. Forging performance: metal materials under plastic deformation without fracture in the course of forging processing ability. Chemical properties: the point at which the metal material with the surrounding medium and contact resistance performance of the chemical or electrochemical reaction. Corrosion resistance: the ability to metal material erosion resistance to a variety of media. Oxidation resistance: refers to the metal materials under high temperature, resistant ability to scale. Different forms made by different process and machine equipment, our company precision is a specialized manufacturer of stamping parts. Main: precision shrapnel, terminals, shield, stretching pieces, etc. Through the continuous improvement process can greatly improve the product market competitiveness, not only constantly breakthroughs stamping industry technical difficulties, and form a standard, guarantee the stability of the product, the management idea.
