High Power RF Pyramid Absorber Foam Microwave Absorbing Materials

RF ABSORBER FOR ANECHOIC CHAMBER EMC TEST HIGH QUALITY AND COMPETITIVE PRICE

Foamed EPP particles are uniform in size and have stable properties. The compression molding as following:

• 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.
• Quality testing: Measure the size, shape, and weight of products to pick out inferior-quality products.
• Packing: Pack the products for safe.
