、即ち、ストレスクラックが発生しやすい。In general, ABS resin has good adhesion with paint and affinity with thinner, making it an excellent material for paintable plastics, but in most cases molded products are obtained by injection molding, and as a result, molding conditions Depending on the molded product, residual strain tends to remain on the molded product, and coating defects, ie, stress cracks, are likely to occur during painting, which are thought to be caused by the residual strain.
特にこのストレスクラックの発生は射出時に剪断応力が
大きく作用するゲート付近に発生しやすい。In particular, stress cracks are more likely to occur near the gate where shearing stress acts heavily during injection.
