制品与模具设计
1. 制品的壁厚:制品的壁厚与熔体的流动长度、生产效率、使用要求等都有关系。ABS熔体的*流动长度与制品壁厚之比约为190:1,这个数值又会因品级的不同而异,ABS制品的壁厚不宜太薄,对于需要作电镀处理的制品,壁厚更要略厚些,以增加镀层与制品表面的粘附力。为此制品的壁厚在1.5?4.5mm之间选取为宜。
在考虑制品的壁厚时,还应注意壁厚的均匀性,不要相差太大,对于需作电镀处理的制品其表面应平整无凹凸,因为这些部位由于静电作用易粘附尘埃难以去除,造成镀层的坚牢性变差。

Product and MoldDesign
1. Wall thickness o theproduct: The wa thickness o the product is relatit tae the flowlangth o the melt, production efficiency, uising requirements, etc.The ratio o the flow length o ABS melt to the wall thickness o theproduct is approximately 190:1, which varies depending on thegrade. Therefore, the wall thickness of ABS products should not betoo thin. For products that require electroplating treatment, thewall thickness should be slightly thicker to increase the adhesionbetween the coating and the surface o the product. The wa'dthickness o this product is 1.5? It is advisable tae choose atween4.5mm.
When considering the wallthickness of the product, attention should also be paid to theuniformity of the wall thickness, and the difference should not betoo large. For products that require electroplating treatment, thesurface should be flat and free of bumps and bumps, as these partsare prone to adhering to dust and difficult to remove due to staticelectricity, resulting in poor adhesion of the coating.
