Introduction of Foam #6 Recycling Process
The process of foam #6 recycling can be divided into three steps including foam volume reduction, foam granulation and rebirth to new products.

Backgrounds of Foam Recycling.

Foam #6 has become the main material of the packaging industry due to its advantages of light weight, high strength, corrosion resistance, and good barrier to water vapor.
At the same time, the number of abandoned foam is increasing, and the pollution problem follows. Foam recycling is not only conducive to the protection of the ecological environment, but also has important practical significance for the sustained and healthy development of economy and society.
Foam Volume Reduction
In order to facilitate foam storage and transportation, many recyclers use foam #6 compactor to crush and compress the foam, which is the most effective way of foam volume reduction. With screw compression principle, during the use, the operator only needs to put the foam scrap into the hopper and it will be break into pieces by a crushing knife.

Some foam compactors adopt the principle of cold compaction without the need of heating. Another kind of compactor needs to be heated during the operation to turn the foam into semi-solid ingots. The choice of foam recycling machine depends on the type of foam, including humidity, hardness, size and so on. It also depends on the local government's usage policy and the budget of recyclers.
Foam Granulation
Before the foam is made into a new product, the step of foam granulation is indispensable. Foam granulator, an environmentally friendly mechanical equipment, the rotating screw of which will twist the foam into clusters.

The foam #6 rolls forward in the screw groove, and the screw continuously cuts off, squeezes and stirs it. When mixed and plasticized, the foam is turned into a viscous liquid, and then flows to the machine output at high temperature and high pressure. Finally we will get foam pellets in the shape we need.
Rebirth to New Products
This is the last step of foam recycling, turning waste into treasure, to make plastic foam #6 into decorative frame with natural wood texture. The steps are as follows:

(1) Heat the foam pellets and press it into a blank frame.
(2) Apply mud on the blank frame and put it into the model for natural drying.
(3) Sand the mud layer surface of the blank frame.
(4) On the surface of the sanded blank frame, the embossing mud is dried naturally with a embossing wheel.
(5) Spray base color paint, dry naturally.
(6) After repairing, spray paint and dry naturally.
(7) Polish after surface modification.
(8) Polishing after wax spraying.
(9) Package the finished product after natural drying.
