What are the misunderstandings in the production of water cups? (two)

In the previous article, we talked about some misunderstandings in the production of cup lids. Today we talk about the misunderstandings in the production of cup bodies.

Regardless of whether it is a plastic water cup or a stainless steel water cup body, there will be a diameter ratio of the minimum diameter to the maximum diameter.There is no problem in producing within a reasonable diameter ratio range.Once the diameter ratio is exceeded, it will cause serious production problems and will not be able to produce.

The minimum diameter generally refers to the position of the water spout on the water cup, but it is also because of the shape design on other positions of the water cup body, usually this kind of design is relatively rare.The largest diameter is usually at the position of the belly of the cup, and there are also cups with different shapes at the bottom of the cup.

When the diameter ratio of the plastic water cup is lower than the standard value required by the production process, neither the bottle blowing process nor the injection molding process can be achieved, and the purpose can not be achieved because of different materials.Extrusion and blowing technology can be achieved in the current process, but bottle blowing machines and injection molding machines cannot.However, due to the characteristics of the extrusion process, the quality of the products produced is average.

The lower the diameter ratio of the stainless steel water cup, the more difficult it is to produce.In order to meet the design of the product shape, some products have to perform an annealing process on the cup mouth to ensure that the cup mouth will not burst because the neck is too small.When the diameter ratio of the design drawing is lower than the production standard, it is also impossible to achieve in the current production process of stainless steel water cups.To achieve this, it is necessary to change the product structure, and design and develop targeted production equipment based on the product structure.
