The flowability of foam packaging and its impact on foam products

Thread Content

　　The fluidity of foam packaging has a significant impact on the quality of foam products, mold design, and the molding process. 　　Foam packaging with poor fluidity does not fill the mold cavity easily, which can lead to defects such as underfilling or weld lines; therefore, a higher molding pressure is required to achieve proper molding. On the contrary, foam packaging with good fluidity can be filled into the cavity using lower molding pressure. However, excessive liquidity can cause severe flash and burrs during molding. Therefore, during the molding process of foam products, when selecting the material for these products, it is necessary to choose a foam packaging material with the appropriate flow properties, based on the product’s structure, size, and molding method, in order to obtain satisfactory results. Furthermore, mold design should take into account the fluidity of the foam packaging when determining the parting lines, gating systems, and feeding directions; the choice of molding temperature should also be based on the fluidity of the foam packaging. 　　For more relevant information, please visit our official website at http://www.yybzvip.com for further details on Hefei foam boards.
