Introduction

Styrofoam, also known as expanded polystyrene (EPS), is widely used for its lightweight and insulating properties. A Styrofoam machine facilitates the production of EPS products through a series of stages including pre-expansion, molding, and cooling. This article details the operational mechanics of these machines, focusing on precise parameters and technological solutions offered by leading companies including Dongshan EPS Machinery.

Styrofoam Machine Operations

a. Pre-expansion

The pre-expansion stage involves heating the raw polystyrene beads using steam. The typical operational parameters include maintaining a temperature range of 90°C to 100°C. This process expands the beads to 20-50 times their original size, achieving a density range of 10-30 kg/m³.

b. Molding

In this stage, the pre-expanded beads are placed into metal molds where additional steam is applied to fuse them together. The molds are kept at approximately 110°C to ensure proper fusion and formation of the desired shape. The cycle time for molding can vary from 5 to 10 minutes depending on the product size.

c. Cooling and Shaping

Cooling is achieved by introducing cold air or water to reduce the temperature of the formed EPS blocks. The cooling process typically ranges from 30 to 60 minutes. Successful cooling ensures the structural integrity and dimensional stability of the final product.
