注射成型直接连接（IMDJ）是金属-塑料直接连接方法的一种。IMDJ首先处理金属表面，然后通过注塑技术将熔融聚合物注入表面。IMDJ法由于注塑成型技术的高速生产特点，非常适合大批量生产环境。然而，限制IMDJ应用的因素之一是其连接强度低。在这项研究中，我们通过在工程聚合物聚酰胺6（PA 6）中混合流动改性剂（流动改性剂OSGOL MF-11）来改善连接性能。研究了添加剂用量对连接强度的影响。结果表明，在PA 6中混合OSGOL MF-11是一种提高连接强度的可行方法，最大提高可达75%。通过横截面分析证实了较高流动性对机械联锁的改善。红外光谱分析结果表明，化学相互作用的可能性发生，这使得连接更强大。与改性加工技术相比，添加剂改性材料更容易应用。研究结果为IMDJ的发展提供了新的思路。
Injection molded direct joining (IMDJ) is one type of metal-plastic direct joining methods. IMDJ first treats the metal surface and then injects melted polymer onto the surface via injection molding technology. IMDJ method is excellently suitable for a mass production environment for the injection molding technology characteristics of high-speed production. However, one of the factors limiting the application of IMDJ is its low joining strength. In this study, we improved joining performance by mixing a flow modifier (flow modifier OSGOL MF-11) in the engineering polymer polyamide 6 (PA6). We studied the influence of the additive amount on the joining strength. It was found that mixing OSGOL MF-11 in PA6 is a feasible method to improve the joining strength, with maximum improvement by up to 75%. The mechanical interlocking improvement by higher fluidity was confirmed by cross-sectional analysis. FTIR spectra analysis results showed the possibility of chemical interaction occurrence, which causes the joint to be more robust. Materials modification by additives is much easier to apply compared to modification processing technology. The results provide new ideas for IMDJ development.
