新型汽车用注塑表皮软质仪表板的开发和研究

Development and Research of A New Type of Injection Moulded Skin Soft Instrument Panel for Vehicle

软质仪表板由于其优异的质量与触感在汽车市场具有广阔的应用前景,文章提出一种新型汽车用注塑表皮软质仪表板,通过分析注塑工艺与仪表板结构特点,阐述注塑工艺成型软质仪表板表皮的优势,识别并解决注塑表皮工艺面临的表皮质量缺陷、气囊区域弱化以及表皮与发泡层抗发粘等难题,并试制注塑表皮软质仪表板。结果表明:新型注塑表皮软质仪表板可以达到传统PVC搪塑表皮仪表板的效果,同时具有生产周期短、成本低、低VOC及轻量化等优势,该注塑表皮可以应用于量产车型。

The soft instrument panel has broad application prospects in the automotive mar⁃ket due to its excellent quality and tactility.An innovative soft instrument panel with injection-molded cuticle is developed,by analyzing the characteristics of injection molding process and instrument panel structure,illustrating the advantages of injection-molded cuticle,also identifying and solving problems of injection molding process for soft instrument panel cuticle,such as quality defects of the cuticle's surface,weakening of the airbag area and the poor stickiness between cuticle and foam layer,and manufacturing the soft instrument panel with injection-molded cuticle.The results show that the new soft instrument panel with injection-molded cuticle can achieve the effect of the tradi⁃tional instrument panel with PVC slush plastic cuticle,also has the advantages of short manufacturing cycle,low cost,great VOC and light weight.In addition,the injection-molded cuticle can be applied to mass-produced models.
