If you are in the field of refrigeration, you will always hear the term-foam. For example, your customer may ask you: What is the thickness of your foam layer? What is your foam density? Obviously, they all attach great importance to this issue.
Foaming process
First, let us roughly understand what the foaming process is. Before this procedure, we need to choose a suitable foam material. Of course, different factories will choose different foaming materials. At MEIBAIJIA, we usually choose Japanese imported brands to ensure foaming stability. For some small factories, they may use low-quality materials to control costs and ensure profits. After confirming the material, we need to put the freezer in the foaming mold, and then inject the foaming material into the mold to start the foaming process.
Foam mold
The foam mold is very important in the whole process. At MEIBAIJIA, we have different molds of different models, so once the mold is used, the size is fixed and the thickness of the foam layer is also fixed. Why do we use foam molds instead of labor? By using the integral foaming mold, the uniformity, stability and uniformity of the foamed layer can be ensured, thereby ensuring the insulation effect. Of course, the thickness and density of the forming layer are critical in this process.
foaming material
The foam layer is like human clothes, the more you wear, the warmer you feel, so you can keep it cold and keep warm. Foaming materials are like clothing materials. If you choose a sweater, cold air can still enter, and if you choose a jacket, then you can effectively prevent cold air. This is why in the past (when we were young), suppliers always put a quilt on the top of the chest freezer to keep it cold.
We know that the cooling system is the core of refrigeration, and in order to obtain a specific low temperature, we cannot manufacture the cooling system without the help of a thick foam layer. Usually chest freezers. In this industry, the thickness of the foam layer used for freezers is 6.5cm. In Ningbo Zhuoqiu, we all use different sizes of 7.5cm-9cm to reduce energy consumption and thus reduce electricity bills.
