Raw material input: EPS (expandable polystyrene) granule raw material is conveyed into the pre-expander.
Heating expansion: EPS granules are heated by passing wet steam, which softens the polystyrene granules and activates the foaming agent dissolved in them. The foaming agent evaporates, causing the softened granules to expand and form pre-expanded polystyrene beads.
Cooling and stabilization: The pre-expanded EPS beads are cooled and stabilized by air cushions in the fluidized bed for subsequent processing and use.
High℃of automation: It can realize functions such as automatic feeding, electronic weighing, temperature control, and material level control, reducing the need for manual operation and improving production efficiency and accuracy.
High efficiency and energy saving: The use of advanced technology and design can quickly and evenly heat EPS granules, making the foaming process more efficient while saving energy consumption. For example, some pre-expanders use fully enclosed foaming barrels and pressure sensor control technology, which can continuously sample, make the foaming pressure more constant, and improve thermal efficiency.
Good product quality: Precise temperature control and material level control ensure uniform foaming density of EPS beads with small error, which improves product quality and stability.
Easy operation: Equipped with PLC programmable controller and touch screen and other operation interfaces, it is simple and convenient to operate, easy to master and use.
Strong adaptability: According to different production needs, the foaming parameters can be adjusted to produce EPS pre-foamed beads of different densities and specifications.
Packaging industry: used to produce EPS foam packaging materials, such as electronic product packaging, food packaging, handicraft packaging, etc. Pre-foamed EPS beads have good cushioning properties and can protect products from damage during transportation and storage.
Construction industry: EPS foam building components such as insulation boards and decorative lines can be manufactured. These components have the advantages of light weight, heat preservation and heat insulation, and are widely used in building exterior wall insulation, interior decoration and other fields.
Crafts production: Provide raw materials for the production of EPS foam crafts, such as sculptures, models, etc. Complex shapes and fine details can be achieved, providing creative space for artists and craftsmen.
Market advantages: With the increasing demand for EPS foam materials in various industries, EPS fully automatic and efficient pre-expanding machine has broad market prospects. Its high efficiency and automation characteristics can meet the needs of large-scale production, improve production efficiency and product quality, reduce production costs, and bring greater economic benefits to enterprises.
