Types of Polystyrene Moulding
Injection Moulding:
Used for solid polystyrene (GPPS or HIPS - High Impact Polystyrene).
Molten polystyrene is injected into a mold under high pressure.
Ideal for producing rigid, high-precision parts like disposable cutlery, CD cases, and toys.
Bead Foam Moulding (EPS Moulding):
Used for expanded polystyrene (EPS).
Pre-expanded EPS beads are placed in a mold and fused together using steam.
Commonly used for packaging, insulation panels, and lightweight construction materials.
Compression Moulding:
Polystyrene material is placed in a mold and compressed under heat and pressure.
Suitable for producing large, low-density foam products like cushions and mattresses.
Thermoforming:
Polystyrene sheets are heated and formed into shapes using molds.
Used for producing disposable food containers, trays, and blister packs.
Key Steps in Polystyrene Moulding
Material Preparation:
For EPS: Pre-expand raw beads using steam.
For GPPS/HIPS: Melt the polystyrene pellets in an injection moulding machine.
Moulding Process:
Inject, compress, or steam the polystyrene material into the mold.
Apply heat and pressure to shape the material.
Cooling:
Cool the mold to solidify the polystyrene into the desired shape.
Ejection:
Remove the finished product from the mold.
Post-Processing:
Trim, cut, or finish the product as needed.
Applications of Polystyrene Moulding
Packaging:
Protective packaging for electronics, appliances, and fragile items.
Custom-shaped inserts for shipping boxes.
Construction:
Insulation panels for walls, roofs, and floors.
Lightweight concrete forms (e.g., ICF blocks).
Consumer Goods:
Disposable food containers, drink cups, and coolers.
Toys, CD cases, and household items.
Industrial:
Buoyancy aids, flotation devices, and marine applications.
Prototypes, molds, and patterns.
