Hello, I want to ask, in Meiling refrigerator factory, black and white materials are used for box foaming. I want to ask, if it is made by myself, what is the proportion of white material?

The batching room is one of the key positions in the company, and the proportion of ingredients will directly affect the foaming effect. Before entering this position, you must undergo training.

The company's process engineering department has engineers in charge of foaming process, production workshops and technicians who can guide your work. The master in the batching room must guide the ratio of black and white materials to white materials. This is basic common sense. As for why he told you, he didn't know, and neither did I.

If you can, you can leave your factory and workplace by private mail, and you can contact professional engineers.
