PEI-SABIC Ultem 2300 Tooling & Glass Fiber Processing Guide
Molding a 30% glass-filled semi-crystalline/amorphous composite like Ultem 2300 requires strict moisture control and optimized gating to prevent abrasive tool wear and warpage:
硬化S136金型（耐摩耗性防止）
30% short glass fibers act as an abrasive medium under high injection speeds. Jucheng’s tooling division prevents cavity erosion by constructing molds with premium S136 stainless tool steel hardened to 48–52 HRC and machined on our 5-axis CNCs, ensuring long-term parting line precision and flash-free parts.
Isotropic Low Shrinkage (Warpage Control)
Being an amorphous resin with glass fiber reinforcement, Ultem 2300 exhibits extremely low and uniform shrinkage (0.20% to 0.40%). We utilize 5-axis CNC machines to cut precise mold cavities and balance cooling paths, preventing uneven thermal contraction and structural warping.
加圧オイル金型温度マトリックス
To prevent surface glass-fibers from floating and reduce internal stresses, mold temperatures must be maintained continuously at 140°C–180°C (284°F to 356°F) using pressurized oil-heating controllers. Slower, uniform packing pressure is applied to ensure full material compaction.
延長乾燥剤予備乾燥プロトコル
PEI is highly hygroscopic. Moisture causes hydrolytic splay, voids, and weld line degradation. We desiccant-dry Ultem 2300 resin at 150°C (302°F) for 4 hours, keeping internal moisture below 0.02% to secure optimal molecular bonds and prevent hydrolytic chain cleavage.
