Factors Affecting the Cost of Thermos


In order to make a high-quality thermos cup with good thermal insulation effect, high-quality materials and complete processes are essential. These two aspects are also important factors that affect the cost of the thermos cup.

In terms of materials, the thermos cups circulating on the market are generally double-layer stainless steel structures. The outer layer is made of 201 stainless steel. Since the inner tank is in contact with drinking water, it uses 304 food-grade stainless steel. This material is resistant to high temperatures and has strong corrosion resistance. 201 stainless steel has poor corrosion resistance and is often used as an industrial material. It can only be used as the outer material of the thermos cup. In order to reduce costs and pursue high profits, some manufacturers will only use 201 stainless steel as the inner liner and outer layer of the cup and claim that the inner liner is 301 stainless steel. On the contrary, some factories regard high quality as a selling point of their products, and even use 304 stainless steel as the outer layer of the thermos cup and 316 stainless steel as the inner liner (more corrosion-resistant than 304 materials). The thickness of the liner is also an important factor affecting the performance and cost of the thermos cup. The more common ones are 0.35mm and 0.4mm. The thicker the liner, the higher the cost.

Factors Affecting the Cost of Thermos

In addition, costs will also be incurred in the assembly process. Pipe material quality and cutting and grinding time are all cost factors. A lot of manpower is involved, and China’s labor costs are relatively low, which is why China can become one of the largest exporters of stainless steel cups.

Different coatings on the surface of the cup will also lead to differences in cost. If customization is involved, certain labor costs will also be incurred.For example, screen printing is a printing technology that requires manual participation and a certain degree of accuracy. The more experienced the operator is, the shorter the operation time will be, and the related labor hours will affect the production cost.

Vacuuming is the most important step in making a thermos cup. The related instruments are expensive and consume a lot of power during the working process. Therefore, the time for vacuuming the cup will also affect the cost. Of course, the longer the vacuuming time can also ensure the heat preservation performance of the cup.

As a buyer, you should consider the above points when encountering a thermos cup product with an unusually low price. Does this product use non-food materials? Is it just a single layer without thermal insulation properties or has it not been vacuumed? In this way, you can avoid being cheated when purchasing and get assurance from merchants. At the same time, as a seller,Food safety and product quality should be given top priority, with honesty as the bottom line.Based on which we can also explain to customers who have questions about the price based on the above points.
