If you’re going to be making EPS foam, you want to make sure you use helpful tools to make you work fast and good. The Guiju Batch Pre Expander Machine is one such machine. This machine will make EPS production an easy, time-saving, and quality-granting process, you will be able to create foam of any shape you want, to produce your package.
Batch Pre Expander Machine operates on the principle of expanding EPS beads, also known as expandable polystyrene beads under the effect of steam and pressure. This is how the beads are made larger and how the foam used in a lot of things, from packaging to insulation, is made.
Not only that it can speed up production, but it can cut down the waste. Inflating the beads to the proper size reduces the likelihood that molds will be overstuffed, and that materials will be wasted. This can save you money in materials and reduce your overall production costs.
Consistency is key when you want to produce high-quality eps foam. Ideal for working at a construction site, batch pre expand the foam to be the same, with Guijiu Batch Pre Expander Machine. That way, each foam production batch meets your needs. This machine evenly expands the beads, ensuring you get the best quality foam.
