We’ve always got the latest tech, the newest trends, and the most talked about labels. This is because, if the length of the small-diameter section 6a is less than 10 mm, epoxy resin 3, whose viscosity has become low, flows into the large-diameter section 6b from the cavity 4 in a short time, so the effect of extruding residual air is small; but if the length of the small-diameter section 6a is more than 50 mm, the viscosity of the epoxy resin 3 in the small-diameter section 6a rises, making it difficult to control the pressure within the cavity 4. The flow of the epoxy resin 3 therefore does not tend to become turbulent and the epoxy resin 3 can easily be made to flow in a fixed direction towards the exhaust port 6 as shown in Figure 2. Also, an injection port 5 for injection of epoxy resin 3 into the cavity 4 is provided at the lower part as shown in this Figure and an exhaust port 6 is provided at the upper part in this Figure.
