Henan Chalco open cell aluminum foam material preparation methods mainly include infiltration casting method, investment casting method, electroplating method, etc., but the most advantageous preparation method is infiltration casting method, which is the pre-treated filler particles Put it directly into the mold or make it into a porous precast block, then put it into the mold, and then preheat to a certain temperature together with the mold, then pour molten metal and pressurize appropriately to allow the metal liquid to penetrate into the filler gap or prefabricate In the block, after cooling and solidifying, a three-dimensional network-connected metal-filler particle composite is formed, the casting is processed into a desired shape, and then the filler particles are removed to obtain the final requiredopen open cell aluminum foam sheet plate
This method can be applied to the production of open cell aluminum foam plate, magnesium, zinc, lead, tin and cast iron, and can cast complex shapes. The open cell aluminum foam developed by Henan Chalco Aluminum fabrication Co., Ltd. has been well received in the world. The open cell aluminum foam plate sheet is widely used in highway sound barriers, noise reduction of submarines, subway tunnel vent mufflers, automobile mufflers, tunnel noise reduction walls, and manufacturing high speeds. Railway sound barriers, noise reduction in swimming pools, manufacturing of light composite armor, etc.
