Embodiment 1

[0039] A. Material selection and melting: Select the stainless aluminum with the weight percentage composition of Example 1 in Table 1 as the raw material. First, preheat at a temperature of 300°C for 5 hours. The purpose of preheating is to remove moisture and oil stains in the stainless aluminum ;Before the raw materials are added to the electric furnace, the electric furnace is heated to 600°C to remove the moisture and other chemical substances adsorbed in the electric furnace, and then the raw materials are added to the electric furnace to melt, and after melting, they are kept at 500°C for 2 hours;

[0040] B. Casting: Cast the above-mentioned molten stainless aluminum material into the mold shown in Figure 3 and Figure 4, and remove hydrogen and other oxidized inclusions in the molten stainless aluminum material by nitrogen degassing, The degassing time is 8 minutes, after degassing and cooling at room temperature for 10 minutes, the mold is opened to make a stainless al...

Embodiment 2

[0043]A. Material selection and melting: Select the stainless aluminum with the composition of Example 2 weight percent in Table 1 as the raw material. First, preheat for 4 hours at a temperature of 400 ° C. The purpose of preheating is to remove moisture and oil stains in the stainless aluminum ;Before the raw materials are added to the electric furnace, the electric furnace is heated at a temperature of 750°C to remove the moisture and other chemical substances adsorbed in the electric furnace, and then the raw materials are added to the electric furnace to melt, and after melting, they are kept at 550°C for 1 hour;

[0044] B. Casting: Cast the above-mentioned molten stainless aluminum material into the mold shown in Figure 3 and Figure 4, and remove hydrogen and other oxidized inclusions in the molten stainless aluminum material by means of compound degassing, The compound used for degassing is 1Kg sodium chloride, which is directly poured into the molten stainless aluminum...

Embodiment 3

[0047] A. Material selection and melting: Select the stainless aluminum with the composition of Example 3 weight percent in Table 1 as the raw material, first preheat at a temperature of 450°C for 3 hours, the purpose of preheating is to remove moisture and oil stains in the stainless aluminum ;Before the raw materials are added to the electric furnace, the electric furnace is heated at a temperature of 850°C to remove the moisture and other chemical substances adsorbed in the electric furnace, and then the raw materials are added to the electric furnace to melt, and after melting, they are kept at 600°C for 0.5 hours;

[0048] B. Casting: Cast the above-mentioned molten stainless aluminum material into the mold shown in Figure 3 and Figure 4, and remove hydrogen and other oxidized inclusions in the molten stainless aluminum material by nitrogen degassing, The degassing time is 8 minutes, after degassing and cooling at room temperature for 30 minutes, the mold is opened to make...

Description

technical field [0001] The invention relates to a manufacturing method of a handle, in particular to a manufacturing method of a stainless aluminum handle, its product and a mold; it belongs to the field of mechanical technology. Background technique [0002] Various existing handles are mainly used for doors or household appliances, and are mainly made of metal materials or plastic materials. Among them, the handles made of metal materials have the advantage of high mechanical strength, but the handles made of copper, cast iron and other materials are relatively heavy , easy to corrode; handles made of stainless steel and other materials have high cost and poor market effect; although handles made of plastic materials have low cost and are not easy to corrode; but their mechanical strength is poor and they are easy to damage. [0003] Chinese patent application (CN02218030.3) relates to a door lock handle, the handle is made of wood and includes a handle part and a stigma p...
