Abstract
A drop box for a rotational molding system includes a substantially rigid outer shell, a substantially rigid inner shell, configured to contain unmelted polymer material, and thermal insulating material, disposed between the inner and outer shells. Substantially rigid bridge material interconnects the inner and outer shells and forms part of the rigid structure thereof. The bridge material is configured to provide a thermal break between the inner and outer shells, to reduce heat transfer therebetween.
