In injection molding and thermoforming, “mold temperature management” is a critically important factor determining product quality. Uneven temperature distribution can cause warping, sink marks, weld line defects, and other issues, making stable mass production difficult. However, in actual molding operations, it is difficult to directly monitor temperature changes within the mold. Consequently, temperature prediction technology using thermal-fluid analysis via CAE (Computer Aided...

1. Introduction In recent years, the introduction of smart meters has been advancing rapidly alongside the sophistication of electricity infrastructure. Particularly since the 2014 revision of the Energy Conservation Law, Japan plans to introduce these meters to all households by 2025. The market size is projected to reach approximately ¥30 billion, with total installations expected to hit around 78 million units. To meet this large-scale demand, establishing a high-quality and stable mass...

Introduction In sheet metal fabrication, distortion caused by welding and warping are unavoidable challenges. Even when manufacturing strictly to design drawings, it is not uncommon for the finished product to warp, making assembly difficult. So why does such deformation occur when welding? This article explains the causes, mechanisms, and countermeasures in detail. 1. The effect of heat generated during welding Welding is a method of joining metals by locally melting them using a heat source...
