With the increasing requirements for the function of electric gourd, the application of materials is getting higher and higher, and the tensile strength, hardness, extension rate and anti -fatigue intensity of the motor shell and pulleys have increased. The newer "three -in -one institution" makes its overall structure compact and beautiful. Electric gourds that develop special functions in special industries, such as explosion -proof electric gourds, anti -frozen electric gourds, anti -static, insulated electric gourds, high -intensity anti -corrosion electric gourds, etc., are also the general trend. The first 10 years is just a prologue, and it will create more innovative and vibrant opportunities in the future.
