Apparent Melt Viscosity

Figure 4-2-1 and 4-2-2 show the shear rate dependence and temperature dependence シークレット カジノ the apparent melt viscosity シークレット カジノ SUMIKASUPER LCP, respectively. Compared to other engineering plastics, the apparent melt viscosity シークレット カジノ SUMIKASUPER LCP is greatly affected by both the shear rate and temperature. Therefore, moldability depends greatly on the injection speed, cylinder temperature, and shear heat generated during injection molding. The low viscosity and high shear rate dependence シークレット カジノ SUMIKASUPER LCP make high-speed injection molding possible since the pressure does not easily increase even at high injection speed. Its viscosity becomes extremely low under proper injection molding conditions, making it easy to fill thin-walled or complicated-shaped products. On the other hand, for stable production, it is necessary to properly manage the injection speed and cylinder temperature, and to monitor changes in shear force caused by wear or other factors.

シークレット カジノ Flowability

The thin-wall flow length シークレット カジノ SUMIKASUPER LCP depends on the molding conditions and mold shape. Figure 4-2-7 shows the results シークレット カジノ thin-wall flow length evaluation for various grades molded at the same injection speed and pressure using the same mold as shown in Figure 4-2-6. SUMIKASUPER LCP has high flowability even a product thickness シークレット カジノ 0.1mm, and a wide range シークレット カジノ molding conditions can be applied, allowing it to be utilized in products シークレット カジノ various shapes.
