[With Improvement Examples!] Improved Moldability with 〇〇 Processing *Resin, Plastic Molds

The weld and sink marks in plastic injection molding may be caused by the easily solidifying surface condition of the mold. Please try surface modification through blasting!

1. Let's increase the gates to address poor filling ⇒ Welds have occurred. Has this ever happened to you? ■ Increase the gates ⇒ The number of resin junction points increases with the number of gates, resulting in welds. By blasting the mold surface, it alleviates visually (the surface becomes matte, making it less noticeable) and expands the range of molding conditions (the fine unevenness reduces heat transfer from the resin to the mold, slowing the growth of the solidification layer, increasing injection pressure, and enhancing transferability, which alleviates weld depth). ◎ Result: Appearance defects are improved. ◎ 2. Adopting pin gates and submarine gates ⇒ Sink marks occur. Has this ever happened to you? ■ Increase the holding pressure setting. ⇒ The gate seal occurs quickly, and the filling density does not increase as desired. By blasting the mold surface, it expands the range of molding conditions (the fine unevenness reduces heat transfer from the resin to the mold, slows the growth of the solidification layer, increases injection pressure, and enhances the filling density of the resin up to the gate seal, which alleviates sink mark levels). ◎ Result: Appearance defects are improved. ◎ 【There might be such advantages!?】 - The range of molding conditions expands, stabilizing productivity - Warping and deformation are reduced - Injection pressure can be reduced
