采用各种结构的ПА6 11型再生聚酰胺零件可降低机器、仪表的生产成本和制造劳动强度,也可减轻它们的重量,还可减少金属消耗量。但是,用加压筒铸造法制造的聚酰胺零件的使用经验表明,在许多情况下,这种零件因耐磨性低而不能满足使用的要求。对耐磨性,在很大程度上,受聚酰胺熔体在压模内的凝固条件影响。用加压筒铸造法充填现有结构的压模时,通常在氮气压力下,聚酰胺熔体由加压器浇铸箱挤出。压模腔充满熔体后,拔掉熔体输送连接管,熔体在无压力的情况下凝固。这就导致热塑材料在自由状态下收缩,也导致它们形成《多孔》组织,这是用上述方法铸出ПА6(?)1型聚酰胺零件(尤其是用加压
The use of various configurations of ПА6 11 Recycled Polyamide parts reduces the production costs of machines, gauges and labor intensity, as well as reducing their weight and reducing metal consumption. However, the experience with the use of polyamide parts made by pressurized cylinder casting shows that, in many cases, such parts can not meet the requirements due to their low abrasion resistance. The abrasion resistance, to a large extent, is influenced by the solidification conditions of the polyamide melt in the stamper. In the case of filling the stamper of the existing construction by a pressurized cylinder casting method, the polyamide melt is normally extruded under pressure from a pressurized casting tank under nitrogen pressure. After the mold cavity is filled with melt, unplug the melt delivery connector and the melt solidifies without pressure. This leads to the shrinkage of the thermoplastic material in the free state, which leads to the formation of “porous” tissue, by casting of the ПА6 (?) Type 1 polyamide part,
