グリルエリアのP20鋼をベリリウム銅(BeCu)に置き換えました。BeCuは鋼よりも3~4倍速く熱を伝導し、内部のウォーターラインなしで「ブレード」が熱をメインモールドベースに放散できるようにします。
Key Takeaways An open area ratio of 50–65% balances airflow performance with mold steel durability; exceeding 70% risks blade fracture within 10,000 cycles. Steel blade thickness must match air slot width; slots narrower than 3 mm leave steel blades that cannot be internally water-cooled and overheat. Knit lines in grille ribs retain only 60–80% of base material strength — managing them through gate placement is mandatory. Shut-off surfaces require 3–7° draft angle to prevent galling and flash as the mold accumulates wear. Beryllium copper inserts in blade areas reduce mold temperature by 15–20°C, cutting cycle time by up to 25%. What Is the Core Trade-Off in Molded Grille Design? The […]
