Manufacturer-made, that's what people often say, see, and hear. Those unfamiliar with the production process might think that the factory's operations are solely about production, naturally overlooking design and installation. In fact, many factories, like antique window and door manufacturers, integrate design, production, and installation into one. Think about it; before any item is made, a prototype is needed, so how could there be no design phase in the factory?

Take the antique window and door factory as an example. There are numerous antique window and door factories on the market, facing intense competition, yet many of their designs are quite similar. Just like clothing, there are many knockoff styles available, but upon closer inspection, one can notice subtle design modifications. However, such "innovations" are insufficient to meet consumer demands. Therefore, modern antique window and door factories are taking a hands-on approach to design, being very particular. Only by standing out in product design can they attract more consumers.

After designers at the antique window and door factory design new product styles, they need to test the production. Once there are no issues, they begin mass production. The collaboration between machines and labor ensures that there are no significant problems in large-scale production.

Installation follows. This aspect is primarily aimed at consumers. After the products are manufactured, the antique window and door factory needs to take protective measures, adding a protective layer. Moreover, many consumers order a set of antique windows and doors from the factory but are not skilled in manual installation, so the antique window and door factory will send several skilled artisans to assist the consumers.
