 The foam beads before molding are not cured well, which will cause defects such as insufficient filling during molding and filling. The moisture content in the poorly cooked beads is large, and the resilience of the beads is poor. |
 In the pressurized feeding tank, several foam beads are easy to stick together. When molding and filling, the foam beads have poor fluidity and are prone to insufficient filling defects. |
 The foam beads before molding are not cured well, which will lead to poor re-expansion ability of foam beads during foam molding.The moisture content of the poorly cooked beads is large. During foaming, the internal water is evaporated to be converted into water vapor. In the process, a large amount of heat must be absorbed. |
 As a result, the foam beads have a poor re-expansion capacity during the secondary foam molding. If you want to do a good job in this case, you can only complete it by increasing the density of the beads during pre-launch.The density is too high, which will lead to other defects. |
