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.
