Expanded Polystyrene (EPS foam) is such a fun material - because we can use it for so many things, such as packaging or to keep things warm or things cold. Special machines, which are known as EPS foam machines are used to produce EPS foam. These machines are, in part, whipping those tiny beads of polystyrene into the big, fluffy blocks of foam we all know. At Guiju we are dedicated to utilizing EPS foam machines to produce products that are superior and safer for you.
EPS foam machines function by feeding small grains of polystyrene and blowing burning steam down into them. This causes the beads to get bigger and connect to one another, turning into a solid block of foam. We can then cut it up into different shapes and sizes to package things like electronics, furniture and, yes, food.
There are several advantages to using EPS foam machine. EPS foam is extremely light, so it doesn’t add weight to packages. It’s also really good at protecting things, because it’s shock absorbent. That’s why we use it so often in coolers and refrigerators to keep things warm or cold.

A neat process to make EPS foam with an EPS foam machine. We started by loading the machine with polystyrene beads. Then, hot steam is pumped through the beads to cause them to expand. The expanded beads are then compressed together to make a large block of foam. Finally, we shape cut the foam into whatever shapes and sizes that we need. It’s not a complicated thing, but to do it well takes skill.

So when deciding on an EPS foam machine for your business, consider a few things. Think about the size of the machine, how much it can produce and the quality of the foam it produces. You’ll also want to find a machine that is user-friendly, and easy to clean. At Guiju, we offer multiple EPS foam machines to cater to all types of business requirement so you can choose the one that’s right for you.

At Guiju we can always be doing something to improve our EPS foam machines. We investigate new technologies so that our machines are quicker, more viable environmentally, and friendlier to the environment. We are exploring new methods of recycling and reusing EPS foam to support the Earth. You just do not find anything like this anywhere else in EPS foam equipment production equipment.
