An EPS Continuous pre-expander is a device that allows the expansion of EPS resin several times. This machine is suitable for small-scale manufacturers due to its low investment and simple operation. This device is able to pre-expand a fixed volume of EPS resin several times, resulting in a superior final product. To learn more about EPS Continuous pre-expanders, read on!


EPS Continuous pre-expander machines are highly efficient and offer higher production rates than batch-expander machines. They can expand EPS raw materials in two levels simultaneously, resulting in uniform density of 12g/l. In addition to being more efficient, these machines are cheaper to purchase than batch-expander machines. They can also be more efficient because they use less steam than batch pre-expander machines.


An EPS Continuous Pre-Expander machine is equipped with two feeding devices and a pneumatic conveyor. The fluidized bed ensures uniform air diffusion and speeds up the discharging process. Pneumatic conveyors ensure smooth discharging of materials. The pneumatic conveyors offer a high level of strength, stability, and safety. The machine's compact design facilitates easy access to all components and ensures safe operation.


EPS Continuous Pre-expander machines are mechanically controlled machines that move raw EPS materials. They begin by filling a screw conveyor that moves the material to the expansion loader. During steaming, an agitating shaft continuously moves the material to maintain an even density. Afterward, the raw material continues moving up until the level of the discharge opening port. As soon as the material reaches the level of the discharging opening port, it flows out automatically.


The Pre-expander is an important part of the production process for EPS. It is essential to control the density of EPS raw beads before the molding process. Otherwise, the expanded material will not be able to be used to form packaging products and blocks. This is why EPS Continuous Pre-expanders are so popular. They are available with complete specifications and OEM service. The manufacturer also offers trade assurance and OEM services.
