Fire retardant foam pyramid microwave absorber for shielding room
- Input: EPP particles are suctioned into stock bin by suction system, and weighed for storage for use.
- Load pressure: Pre-pressing can improve the deformation caused by transportation and increase the stability of products after molding, too. The pre-pressing system conclude six steps, that is, venting, weighing, suction, setting parameters, starting, and discharging.
- Molding: Mould is designed according to the shape of absorber, here the foam absorber is pyramid shape. Before molding, following steps should to be done to get best molding condition: fixing mould, adjusting mould, setting parameters, pre-heating, suction and discharging. In molding process, it includes: closing moulds, suction, steam heating, cooling and stabilization, demould.
- Drying: The surface of products taken out from mould has vapor and the product inside contains residual water. So drying is needed to ensure stable dimension.
- Post-process: Smooth the edges and corners, correct local deformation.
