The cost depends on the value of the product. Of course, it is best to solve the problem and reduce the cost, but the design cannot always trap the low price. The design function of the low price product is not to roll but to see if it can obtain higher value. The low price will always lead the whole industrial chain to fall into busy fatigue. The appropriate increase in cost and manufacturing premium will attract different consumer groups. I think I am happy to have a higher price.

I think this cost is OK, this cost control should start with color separation and control to two sets of molds. if it is the division form of the third picture, that is, cream color is divided into two sets, transparent parts and electroplating parts are divided into one set, electroplating will be OK when the time comes, and the price difference in gram weight should not be too much in the market. the main reason is that the mold cost control should be no problem and spread out evenly, this design is still good.
If it is the method of the second picture, it can be divided into a transparent electroplating set, a plastic two-color set, and a throttle valve on the grinding tool, which is a little higher cost.
The conclusion is that the appearance is pretty good, it is different from the market, and the structure and cost are controlled by methods, which is not bad.
