Problems solved by technology

[0002] Tin utensils have a long history. The existing tin products are soft in texture, not easy to process, and lack of practicability. For some high-value storage items, such as high-grade tea, important, etc., tin storage tanks are generally used for storage. It is necessary to have a tin alloy material with higher purity of tin content and higher hardness, which can also be processed in a variety of ways to support the production

Embodiment 1

[0030] Embodiment one: a kind of molding process of tin alloy, comprises the following steps:

[0031] Step 1, tin alloy synthesis: add tin ingots, Bi and Ag in a weight ratio of 1:0.1-0.3:0.4-0.6 to the electric melting furnace, melt the tin ingots at 300°C, add Bi, stir for 5 minutes to mix evenly, When the temperature reaches 500°C, add Ag and stir for 5 minutes to form a tin alloy solution; tin has non-toxic and tasteless properties, adding silver has antibacterial effect, bismuth improves hardness, and the tin ingot must be completely melted after the temperature reaches 300°C , and continue stirring for 5 minutes after adding Ag and Bi to ensure full uniformity. It should be noted that Ag can only be added when the temperature reaches 500 ° C, and it contains a small amount of Sn and other impurities with a content of less than 0.1%.

[0032] Step 2, molding, including casting molding or stamping molding;

[0033] Casting molding, including metal mold casting or silicon...

Embodiment 2

[0039] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the tin ingot, Bi and Ag are heated and melted at 300°C according to the weight ratio of 1:0.1~0.3:0.4~0.6, and the There is also a small amount of Sn and other impurities with a content of less than 0.08%.

[0040] The advantages of the present invention are:

[0041] The design of the technological process of the present invention is reasonable and simple. Tin ingot is used as the matrix, Ag and Bi are added, and the balance is Sn and a small amount of other impurities. After the subsequent machining, grinding, polishing and other processes, the surface quality and aesthetics of tin alloy products are improved, and the products are more durable, and the collection value of the products is comprehensively improved.

Abstract

The invention discloses a tin alloy forming process. The process comprises the following steps of, step 1, tin alloy synthesis: specifically, adding a tin ingot, Bi and Ag in a weight ratio of 1: 0.1- 0.3:0.4 - 0.6 into an electric melting furnace, melting the tin ingot at 300 DEG C, adding Bi, stirring for 5 minutes for uniform mixing, adding Ag when the temperature reaches 500 DEG C or below, and stirring for 5 minutes for uniform mixing to form a tin alloy solution; step 2, casting forming or punch forming; Step 3, machining treatment; step 4, scrubing treatment; step 5, polishing treatment; and step 6, cleaning and packaging. According to the process, tin ingot serves as a matrix, Ag, Bi, the balance Sn and a small amount of other impurities are added, and the solidified tin alloy solution is high in hardness after being subjected to casting forming or punch forming, so that various machining properties can be met; the surface quality and attractiveness of a tin alloy product areimproved after subsequent machining, scrubbing, polishing and other treatments are carried out; and the product is more durable, and the collection value of the product is comprehensively improved.
