Development of EPS Foam Recycling Machine


Kwanchai Saeweenan


        The research paper is aimed to develop EPS foam recycling machine which made in cooperation with the KPM Center Molding Company Limited. The EPS foam recycling machine can solve the problem about the limited of area to store EPS foam scraps from the production process and high cost of transportation the EPS foam scraps. The researcher studied the data from the experiments and the related theories to design and construct the EPS foam recycling machine.

The material of the machine consisting of many main parts such as size of machine 2,019 mm x 2,720 mm x 2,900 mm, machine structure, machine base, hitting and stirring set, foam material conveying set, foam containing set, extrusion set, danger preventing set, power transmitting set, power source set, temperature controlling set and the work control set etc.

From the tests and the real use of this ESP foam recycling machine, the results show that ESP recycling machine could be really used satisfactorily as the set conditions. The rough-stirring set, and the fine-stirring set could break foam pieces with the maximum size 700 mm x 1,000 mm x 150 mm. The ESP recycling machine could filter the foam size passing the stirring process with the average size about 35 mm x 35 mm x 35 mm and could melt EPS foam approximate 1 kg. per minute.
