During vacuum forming process, it is important to pay attention to several key factors:

1. Material selection: Selecting the right material for your product is important to ensure quality and durability. The material should be able to withstand the heat and pressure during the forming process.

2. Mold design: A well-designed mold is critical to producing high-quality products. The mold should be able to accommodate the size and shape of the product being formed.

3. Heating: It is important to heat the material evenly to prevent warping or uneven thickness. Proper heating can also help to improve the strength and durability of the final product.

4. Vacuum pressure: The vacuum pressure should be carefully controlled to ensure that the material is drawn evenly into the mold and that there are no air pockets or voids.

5. Cooling: After the forming process, the product should be cooled slowly to prevent deformation or cracking. 

These five key factors are important
