In this article, the technical and economic evaluationg has been made for the one time foam tableware and green environmental tableware in raw materials, producting prosses and peoperties.

In order to recycle waste foamed plastic materials,the waste materials were firstly melt,then cooled and crushed,and so the waste foamed plastics aggregate(called EPS aggregate)are obtained.

The research work on technical process of making plastic foam, can improve thetechnology.

The structure and the working process of the foaming mould for the adapter were introduced.

In accordance with the development tendency of CAD, aimed at the present foaming mould, a foaming mould 3D CAD system is developed in this paper, which realizes automation of foaming mould design.
