Mold Fabrication:
A mold is created from EPS foam blocks or beads using hot wire cutting, CNC machining, or manual shaping.
The mold design is determined by the desired shape and size of the final part.
Bead Expansion and Molding:
Polystyrene beads are heated and expanded inside a mold cavity.
As the beads expand, they fuse together, taking the shape of the mold.
Curing and Demolding:
The expanded polystyrene part is allowed to cool and stabilize within the mold.
Once cured, the part is carefully removed from the mold.
The key benefits of EPS mold include:
Lightweight and insulative properties of the polystyrene material
Ability to create complex, custom shapes and geometries
Cost-effective production process for low to medium volume parts
Ease of mold fabrication and modification
Recyclability of the EPS material
EPS molding is commonly used in a variety of industries, such as:
Packaging (protective casings, inserts, and cushions)
Building and construction (insulation, architectural elements)
Automotive (interior components, bumper cores)
Marine (flotation devices, boat hulls)
Aerospace (structural components, thermal insulation)
The versatility and cost-effectiveness of EPS molding make it a popular choice for many product design and manufacturing applications.
