It is clarified that the specimens of smaller mixing and injection machines were smaller variation in weight loss, sintered density and strength.
结果表明，较小的混炼机和注射机制造的试样，重量损失、烧结密度和强度的变化程度较小。

Minimum scrap loss. Runners, gates, and scrap can usually be reground. Recycled thermoplastics can be injection molded.
废料损失最小化：浇道、闸道和废料通常可以重新研磨。循环热塑性塑料可以注塑成型。

After evaluating the route loss and the local loss of the imbalance injection system, the article confirms the relation of the second grade branch radius from the scope of energy.
