The Coralfoam process can be applied to virtually all injection moulded parts. It is particularly suited to a core-back process where both thick and thin sections are required; the foaming occurs only in the thick sections, so the cycle time follows the shorter cooling period of the thin sections, the overall part weight is reduced and the thick sections have increased stiffness. Containers and cups also perform well when a Coralfoam ring is moulded around the diameter, increasing hoop strength and providing thermal insulation. Insulated containers using Coralfoam continue to be of interest to customers.

The products on the right are examples of some of the parts manufactured using both the open-mould (early ejection, repeatable expansion) foaming process as well the closed mould and moving cores (core-back) process.
