What should be paid attention to in the stretching process of stainless steel thermos cup? (I)

Hello everyone, "Dong Dong Talk Cup" is here. Recently, large 40OZ ice cups have been selling well all over the world. Professionals predict that there will be at least 100 million sales in the world in 2025. http://www.zhanyict.com/en/ProductsDetail-VB-10493.htmlThere are many similar ice cups on Amazon. Through data observation, the editor found that the sales of most ice cups are indeed considerable. The editor also bought several different brands and different models to learn, and found that the inner liners of many ice cups use the stretching process. Through data comparison, the editor found that the sales of ice cups using the stretching process are greater than those using the tube drawing process.

Why do water cups made by stretching process sell better than those made by tube drawing process? The main reasons are: 1. Beautiful. Since there are no welding lines on the inner wall, the overall feeling is stronger and more regular and beautiful. 2. Easy to clean. Many consumers like to use dishwashers for cleaning, especially in the European and American markets. http://www.zhanyict.com/en/ProductsDetail-VB-10493.htmlThey will subjectively think that water cups with welding lines inside are not clean. 3. Better thermal insulation performance. Since there are welding lines on the bottom of the tube drawing process, there may be false welding or fine sand holes, which will affect the thermal insulation performance.

Having shared the sales advantages of the stretching process in the market, http://www.zhanyict.com/en/ProductsDetail-VB-10493.htmlthe editor will now share with you what should be paid attention to in the stretching process based on his actual experience in work.

As stretching technology becomes more mature and stretching equipment becomes more advanced, more and more brands and businesses are using stretching technology on more products to meet market demand. http://www.zhanyict.com/en/ProductsDetail-VB-10493.htmlHowever, some manufacturers tend to overlook some precautions when combining stretching technology with product production.

What should we pay attention to during the stretching process?

1. Material selection

In the stretching process, the choice of materials is crucial. Stainless steel materials have different ductility and hardness due to their different compositions and properties. Generally, 304 and 316 stainless steels are more commonly used because they show good comprehensive performance in the manufacture of thermos cups. http://www.zhanyict.com/en/ProductsDetail-VB-10493.htmlChoosing the right material can reduce the probability of cracks and other defects during the stretching process. Compared with 304 stainless steel and 316 stainless steel, 316 stainless steel has higher hardness and is more difficult to stretch than 304 stainless steel under the same structural cup shape.

2. Mold design

Whether it is for product production or process processing, mold design is crucial. Accurate mold design is the prerequisite for achieving high-quality stretch products. http://www.zhanyict.com/en/ProductsDetail-VB-10493.htmlThe mold of the thermos cup needs to be able to distribute force evenly to avoid material damage due to uneven force in a certain part. The smoothness of the mold also needs to be maintained at a high standard to reduce friction with the material. The technical ability of the engineer who designs the mold is also very important. Taking the stretching process as an example, designing one less set of molds or making one more set of molds may cause unnecessary problems in the production of the product.

Due to space constraints, this is the end of the sharing of this issue. http://www.zhanyict.com/en/ProductsDetail-VB-10493.htmlFriends who like Uncle Dong’s articles, please like and follow. See you next time.
