The beads start out in their small form, and are mixed with a special liquid which helps them expand. Then the mix is poured into molds that form the foam. After some time the foam cools and hardens to the shape of the mold. As a result, the foam is light and strong, which is excellent for packing and insulation.
The production line at Guiju is like a giant conveyor belt, transporting the foam from one machine to another. Each machine performs a special chore, such as cutting the foam to the proper size or shaping it into different designs. This advanced line does help Guiju make lots of foam products fast and easy.

Guiju is concerned about the earth, so they have taken special technology that is energy saving in the manufacturing line and by the way they produce the diapers with this technology is at low energy. That means they consume less electricity and generate less waste in the process of making their foam products. Guiju is one of the new generation, helping to defend the Earth by taking advantage of the new technology.

Foam products quality control is very crucial. Guiju tests the foam at every juncture to ensure it’s just right. This will involve a comparison of foam size, shape and strength. With their attention to quality, Guiju ensures they are giving the best foam products to their customers.

Eco-friendly packaging is a high priority for a lot of companies, and EPS foam is an excellent option. Guiju's production line can produce foaming products that can be recycled and can degrade, which is environmentally friendly.
