【Numerous Improvement Examples!】Improved Release Properties with 〇〇 Processing *Resin, Plastic Molds

The issue of "release failure" in plastic injection molding may be caused by difficult-to-polish areas. Please give "surface modification treatment by blasting" a try!

1. Where are you getting stuck? Where are you clinging? Is this not happening? ■ The rise near the PL surface of the insert made by electrical discharge machining ⇒ Discharge marks remain. Even if polished, the polishing marks become perpendicular to the release direction, which may lead to release failure. ◎ Countermeasure: Performing blast processing on the [insufficiently polished areas] will reduce the factors causing sticking and improve release properties. ◎ 2. Have you ever experienced sticking even though you are polishing to a [shiny mirror finish]? ■ To eliminate sticking, increase the grit of the polishing ⇒ If the surface roughness is too smooth (as it approaches a mirror finish), the cause of release failure changes from [sticking] to [adhesion]. ◎ Countermeasure: If [release failure does not improve even after polishing], adding fine irregularities through blast processing will improve release properties. ◎ [Design changes] [Review of molding conditions] ⇒ If defects are not improving, the [surface condition] may be the issue. Please consult with us once! [There may be such advantages too!?] ■ When release resistance decreases... - Cycle time becomes faster - Ejection slopes can be reduced - No sticking to the mold occurs
