How EPS is manufactured?
The conversion of expandable polystyrene to expanded polystyrene is carried out in three stages: Pre-expansion, Maturing/Stabilization/Aging and Shape Molding.
Polystyrene is produced from the crude oil refinery product styrene. For manufacturing expanded polystyrene, the polystyrene beads are impregnated with the foaming agent pentane. Polystyrene granulate is prefoamed at temperatures above 90°C.
This temperature causes the foaming agent to evaporate and hence inflating the thermoplastic base material to 20-50 times its original size.
After this, the beads are stored for 6-12 hrs in aging silos, allowing them to reach equilibrium. Then beads are conveyed to the mold to produce forms suited as per application.
The production works as below.
EPS Pre expander-aging silo-shape molding machine.
Automatic eps machine for expander is necessary eps machine for eps material expansion. Auto batch type controlled by plc and touch screen is fully auto pre expander, equipped with screw conveyor, drying bed, more accurate density, suitable for quality eps products making. Widely used Automatic eps machine for expander is PSJ1100(Chamber diameter), PSJ1300, PSJ1500.
Automatic eps machine for expander PSJ500 is customized expander for high density 50~80g/l beads expansion, like eps helmet.
Below is the automatic eps machine for expander PSJ1500 type with auto screw conveyor and drying bed:
EPS products are widely used in different fields. Can be used to make eps blocks for wall and roof insulation, can be used to pack fragile items as cushions, or used to pack fish or vegetables to keep them fresh, make templates for building houses, or just use beads for making sleeping bags, with cement Mixed to make lightweight concrete, or to make lost foam products for making automotive parts, etc.
More details will be discussed later as request.
