Technical question 1. Why can't the lid of the same water cup be replaced with plastic if it is stainless steel?

I often encounter some questions from customers, which seem reasonable but are difficult to achieve in production. For example, the lid of the same stainless steel vacuum flask is made of stainless steel, can I replace a plastic lid without changing the body structure of the bottle? In other words, if the lid is plastic material, can changed to a stainless steel lid?

This question seems to be very simple, it seems that it is just to change the material, and it shouldn't be difficult to change the lid? In fact, this difficulty is like re-developing a new water cup. Why do you say that?

First of all, the material of the stainless steel cup lid is metal, and the processing technology and the metal mold used for processing the lid are completely different from the plastic lid. The metal processing mold department can be used in the production of plastics, and the same plastic product molds cannot be used in the processing of metal products.

Secondly, the design of each product is matched. If a stainless steel water cup was designed with a stainless steel cup lid as the design direction in the early development, then the development of the cup body mold, the structure treatment and the design of the twisted teeth of the cup have obvious characteristics. Only in this way can it fit perfectly with the stainless steel cup lid.
