The invention provides an injection molding part for an automobile front bumper assembly, a manufacturing method, a mold and an automobile, and relates to the technical field of automobile front bumper assemblies. The injection molding part is made of a polypropylene composite material, and the polypropylene composite material comprises the following components in parts by weight: 70-75 parts of high-crystallinity co-polypropylene, 5-10 parts of a toughening agent, 15-20 parts of talcum powder and 0.3-0.5 part of crystal whiskers. Wherein the mesh number of the talcum powder is 2000 to 3000 meshes. Thus, by modifying the polypropylene composite material, the weight of the injection molding part which is made of the polypropylene composite material and can meet the requirements for the modal, the strength and the rigidity of the front bumper assembly can be light, and the weight of an automobile can be reduced.

    本申请提供一种用于汽车前保险杠总成的注塑件及制造方法、模具、汽车,涉及汽车前保险杠总成技术领域。该注塑件由聚丙烯复合材料制成,聚丙烯复合材料包括按重量份计数的如下成分:高结晶共聚聚丙烯70‑75份、增韧剂5‑10份、滑石粉15‑20份、晶须0.3‑0.5份。其中,滑石粉的目数为2000‑3000目。这样,通过对聚丙烯复合材料进行改性,可使由聚丙烯复合材料制成的能够满足前保险杠总成的模态、强度和刚度要求的注塑件的重量较轻,利于减轻汽车的重量。
