The invention relates to the field of automobile parts, and discloses an instrument panel cross beam machining method and an instrument panel cross beam. The instrument panel cross beam machining method adopts an injection molding mode to machine an instrument panel cross beam, and in the injection molding process of the instrument panel cross beam, injection molding is carried out by adopting injection molding parameters of a first injection speed and a first screw rotating speed in a first time period; in the second time period, injection molding parameters of the second injection speed and the second screw rotating speed are adopted for injection molding; wherein the first injection speed is greater than the second injection speed, and the first screw rotation speed is greater than or equal to the second screw rotation speed. Therefore, the distribution of the glass fibers can be optimized only by adjusting the injection molding parameters of the first time period and the second time period, so that the mechanical property of the instrument panel cross beam is improved, and compared with the mode that the content of defects and impurities needs to be accurately controlled in the related technology, the production cost and the production difficulty can be reduced.

    本发明涉及汽车配件领域,公开了一种仪表板横梁加工方法及仪表板横梁。其中,仪表板横梁加工方法采用注塑成型的方式对仪表板横梁进行加工,且在对仪表板横梁进行注塑的过程中,包括:在第一时间段中,采用第一注射速度和第一螺杆转速的注塑参数,进行注塑;在第二时间段中,采用第二注射速度和第二螺杆转速的注塑参数,进行注塑;其中,第一注射速度大于第二注射速度,第一螺杆转速大于或者等于第二螺杆转速。如此,只需调整第一时间段和第二时间段的注塑参数,即可优化玻璃纤维的分布,从而提高仪表板横梁的力学性能,相对于相关技术中需要精确控制缺陷和杂质的含量的方式,能够降低生产成本以及生产难度。
