EPS molds are used to create custom-shaped expanded polystyrene foam products.
Mold Cavity Design:
The mold cavity shape directly determines the final product geometry. Careful 3D modeling and simulations are needed to optimize the cavity design.
Draft angles, ejection mechanisms, and parting line placement are critical for part removal and dimensional accuracy.
Multi-cavity molds allow for higher production volumes in a single cycle.
Bead Fusion:
The EPS beads must properly fuse together within the mold to create a cohesive, structural part.
Bead size, density, and fusion properties affect the mold design and expansion process parameters.
Improper bead fusion can lead to weak points or voids in the final EPS product.
Manufacturability:
Cycle time, demolding, post-processing, and packaging needs must be considered for efficient, high-volume production.
