Foam machinery refers to machinery that manufactures polystyrene foam, that is, EPS foam machinery. The complete set of foam machinery and equipment includes Pre-expander, auto block molding machine，automatic shape molding machine, cutting machine, recycling granulator and auxiliary equipment.
Foam machinery is mainly divided into five categories:
1. Pre-expander is divided into PSJ50-160 automatic batch Pre-expander machine and PSY70-120 continuous Pre-expander.
2. There are many kinds of auto block molding machine, which can be roughly divided into single-door block molding machine, adjustable block molding machine with vacuum, translational block molding machine, vertical block molding machine, etc.
3. Automatic shape molding machine include PSZ100-175T series automatic shape molding machine with vacuum, PSZ100JN-180JN series automatic shape molding machine with vacuum（efficient and save energy type）, which are mainly used in various models. The manufacture of electrical foam packaging, fruit foam boxes, vegetable foam boxes, aquatic product foam boxes and other types of packaging products, the use is very wide.
4. Foam cutting machine is a device that uses electric heating wire cutting, which is specially used for cutting various shapes of foam products. There are A-type foam cutting machines, C-type foam cutting machines, and two-dimensional and three-dimensional foam cutting machines.
5. Among them, the recycling equipment is composed of foam crusher, foam granulator, and granulator, which is the process of crushing-plasticizing, drawing strips-cutting and other processes. Equipment for recycling.
