What can be done with our processing technology: Improvement of weld line strength.
Achieving high weld line strength with our independently developed IMM method, we create parts with stable strength and high reliability.
A weld line is the location where molten resin meets within the mold during injection molding, resulting in a Y-shaped groove at the junction. Particularly in the case of fiber-reinforced resins, the fibers at the junction are oriented differently than in other areas, leading to a significant reduction in strength. The "IMM method" is a type of compression molding technology that allows molten resin to flow into the cavity through a compression action. Similar to the IMP method, it offers flexibility in product shape. By intentionally altering the internal flow of molten resin during injection to disperse the weld lines, we can change the fiber orientation and improve the strength at the weld line area. While the V-shaped groove may become shallower, it cannot be completely eliminated. Therefore, please consider this as a different technique from the "Heat & Cool technology" aimed at improving appearance. It is possible to address this through modifications to existing molds. 【We can solve the following issues】 - I want to increase the strength of the weld line to a higher level. - I am selecting unnecessary materials to increase weld line strength. - I am increasing the wall thickness to address the weld line strength.
