Ultramide A3EG10 Mechanical Stiffness & Extreme HDT Profile
Ultramid® A3EG10 is a 50% glass fiber reinforced semi-crystalline PA66 injection molding grade engineered by BASF, formulated to provide outstanding strength, maximum rigidity, and excellent heat resistance under ISO/ASTM standards:
| 물리적 및 강도 파라미터 | Ultramid A3EG10 Value (DAM / ISO) | Metal Replacement Advantage |
|---|---|---|
| 구조적 강성 | Tensile Modulus 16,500 MPa / Strength 230 MPa | Delivers metal-matching modulus and creep resistance, allowing it to substitute die-cast zinc and structural aluminum. |
| 열변형 온도(HDT) | 250 °C (DAM @ 1.80 MPa) | Retains outstanding structural stiffness and shape under continuous thermal load in high-heat engine environments. |
| Crystallinity Dimensional stability | Water Absorption 1.9% (Equilibrium 50% RH) | Excellent dimensional stability compared to standard PA66, ensuring low expansion variables. |
Structural Process Configurations for 50% GF Ultramid A3EG10
With its high molecular orientation and extreme glass fiber reinforcement, Ultramid A3EG10 supports structural configurations:
| 성형 기술 등급 | 공정 호환성 및 운영 세부 사항 |
|---|---|
| Structural Bracket Molding | Excellent. Fully optimized for high-strength engine mount brackets, structural cooling frames, and heavy-duty agricultural machine links. |
| Heavy-Duty Industrial Housings | Excellent. Perfect for high-pressure water pump housings, chemical valve bodies, power tool frames, and heavy industrial gearboxes. |
| Insert & Fastener Molding | Excellent. High tensile strength and modulus are ideal for encapsulating metal brass threaded inserts, bolts, and mounting flanges. |
High-Filled GF Wear & Shrinkage Matrix
Molding an ultra-high heat resistant, 50% glass-fiber reinforced PA66 like Ultramid A3EG10 requires strict mold temperature control and abrasive-wear prevention:
고연마 공구 마모 제어
50% short glass fibers act as an aggressive grinding agent under high injection pressures and high melt viscosity. Jucheng’s tooling division prevents cavity erosion by constructing molds with premium hardened tool steel (H13 or S136) heat-treated to 52 HRC, combined with nitriding or PVD wear-resistant ceramic coatings to ensure mold longevity.
휨 없는 등방성 수축 제어
Because of the 50% glass fibers, Ultramid A3EG10 shrinks extremely low in the flow direction (0.30%) but higher perpendicular to the flow (0.70%). We utilize 5-axis CNC machines to cut precise mold cavities and balance cooling paths managed by pressurized water controllers, preventing uneven thermal contraction and structural warping.
Water-Heated Mold Temperature Matrix (Crystallization Control)
We maintain mold temperatures at 80°C–120°C using pressurized oil/water temperature controllers. High mold temperatures maximize surface gloss, reduce weld lines, and prevent surface glass-fibers from floating, ensuring a smooth and non-fibrous finish.
제습 건조 및 휘발분 배출
We dry raw resin in desiccant hopper dryers at 80°C–100°C (176°F–212°F) for 4–6 hours. This eliminates surface splay and prevents weld-line micro-voids, keeping internal moisture strictly below 0.10% (ideally <0.08% for heavy load parts). Precise venting slots (0.015mm depth) are cut along parting lines to exhaust gas during high-melt runs.
