| 熔接线和流痕是免喷涂美学塑料在实际应用中常见的缺陷问题，通过改善产品和模具设计，可有效解决熔接线和流痕的问题。免喷涂美学塑料，一次成型就可以实现产品靓丽外观，便利而且环保，更重要的是——降成本！降成本！降成本! 因此。近几年受到各大家电和汽车厂商的追捧。 Weld line and flow mark are common defects in the practical application of non spraying aesthetic plastics. By improving product and mold design, the problem of weld line and flow mark can be effectively solved. No spraying aesthetic plastic, one molding can achieve beautiful appearance of products, convenient and environmental protection, more importantly - cost reduction! lower corporate costs! Cost reduction! Therefore. In recent years, it has been sought after by major home appliance and automobile manufacturers. 图1 各种效果的美学塑料的外观效果 Fig. 1 appearance of aesthetic plastics with various effects 然而理想很丰满，现实很骨感。当我们还沉浸在如何将具有金属效果的美学塑料应用到更多的产品的美梦里，一张张毁容的美人脸让爱美的我们皱起了眉头，那么缺陷是如何产生的呢？ However, the ideal is plump, the reality is very skinny. When we are still immersed in the dream of how to apply the aesthetic plastic with metal effect to more products, one by one disfigured beauty face makes us frown, then how does the defect occur? 图2 各种产品上的熔接线 Fig. 2 welding line on various products 那上图的缺陷是如何产生的呢？ How do the defects in the above figure come into being? 效果色粉具有较高的径厚比，大多成片状，在注塑过程中会受到流体的剪切场作用发生翻转，在熔体汇合处、浇口附近、壁厚变化、拐弯处等位置产生流痕及熔接线缺陷(图3)。 The effect toner has a high ratio of diameter to thickness, and most of them are flakes. During the injection molding process, it will be overturned by the shear field of the fluid, resulting in flow marks and weld line defects at the melt confluence, near the gate, wall thickness changes, and bends (Fig. 3). 图3 色粉在汇合时取向不一致造成结合线 Fig. 3 color powder in the convergence of the orientation is not consistent, resulting in the combination line 办法总比问题多，各大效果色粉专家，材料技术大拿，模具成型大咖从各个角度给出了一些解决方案，虽然不能完全解决问题，但是在某些产品上，已经具有了相当的技术和商业可实施性。 There are more ways than problems. The major effect toner experts, material technology experts, mold molding masters have given some solutions from various angles. Although they can not completely solve the problem, in some products, it has a considerable technical and commercial feasibility. |
