Design and Construction: EPS molds are typically made from aluminum or steel, although other materials like epoxy or silicone may be used for certain applications. The mold design is crucial in determining the final shape and quality of the EPS foam product. It includes features such as cavities, cores, vents, and cooling channels. The mold is precision-machined to ensure accuracy and consistency in the molded parts.
Mold Inserts: In some cases, EPS molds may have interchangeable inserts or cavities that allow for multiple product variations to be produced using the same mold. This flexibility can be beneficial when manufacturing different sizes or designs of EPS foam products.
Venting: EPS molds often incorporate venting systems to allow for the escape of air and steam during the molding process. Proper venting helps prevent voids or deformities in the molded foam and ensures consistent and high-quality products.
