PEEK-빅트렉스 PEEK 150G
긴 유동 길이를 필요로 하는 복잡한 박벽 형상에서 높은 기계적 무결성과 내화학성을 달성하려면 초유동 슈퍼 폴리머가 필요하며, 빅트렉스의 PEEK 150G는 비강화, 저점도 폴리에테르에테르케톤 매트릭스를 통해 이를 제공합니다. 400°C에서 용융 점도 130 Pa·s, 융점 343°C를 자랑하는 이 고유동 등급은 순수 PEEK의 높은 인장 강도(105 MPa)를 희생하지 않으면서 서브밀리미터 프로파일을 채울 수 있도록 설계되었습니다. ISO 13485 및 IATF 16949 의료 및 자동차 프레임워크 하에 운영되는 주성정밀은 빅트렉스 150G 성형을 전문으로 합니다. S136 스테인리스강 금형을 사용하여 높은 결정화 변수를 제어하고, Zeiss CMM으로 검증된 플래시 없는 마이크로 기어와 박벽 커넥터를 제공합니다.
Victrex PEEK 150G Thin-Wall Flow & Structural Profile
Victrex™ PEEK 150G is an unreinforced, high-flow semi-crystalline Polyetheretherketone resin, certified to deliver outstanding melt flow properties and robust mechanical stiffness under ASTM/ISO standards:
| 물리적 및 강도 파라미터 | Lexan 150G Standard Metric | 정밀 성형 이점 |
|---|---|---|
| Melt Viscosity | Ultra-Low 130 Pa·s (at 400°C) | Enables smooth, low-pressure cavity filling of complex thin-walled medical connectors and micro-gears without short-shot defects. |
| Yield Strength | Tensile Stress at Yield 105 MPa | Retains outstanding structural stiffness and metal-like mechanical load-bearing capacity even in unreinforced configurations. |
| 구조적 연성 | Tensile Elongation at Break 25 – 30% | Provides exceptional structural elongation and dynamic impact toughness compared to standard glass-filled grades, preventing brittle failure. |
Micro-Precision Process Adaptability for Easy-Flow PEEK 150G
With low melt viscosity and integrated high-flow kinetics, PEEK 150G processes predictably inside extremely tight mold cavities:
| 성형 공정 등급 | 공정 호환성 및 운영 세부 사항 |
|---|---|
| Thin-Wall Structural Enclosures | Excellent. The primary process for PEEK 150G. Perfect for sub-millimeter medical connector pins, aerospace conduit guides, and diagnostic cuvettes. |
| Micro-Precision Gears & Components | Excellent. Highly optimized for manufacturing sub-millimeter micro-helical gears, medical diagnostic rotors, and orthopedic target pins. |
| 다중 캐비티 자동 고속 생산 | Excellent. Easy-flow characteristics support rapid, high-pressure injection molding with highly uniform weight and dimensional replication. |
PEEK-Victrex PEEK 150G Dynamic Molding Processing Matrix
Molding an ultra-high fluidity, semi-crystalline super-polymer like PEEK 150G requires high thermal boundaries and micron-level parting lines to prevent flashing:
미크론 수준 플래시 제어(툴링 정밀도)
Because PEEK 150G has exceptional flow capabilities (melt viscosity 130 Pa·s), molten resin can seep easily into minor mold gaps, causing unsightly flashing. Jucheng’s tooling division uses 5-axis CNC machines to achieve micro-tolerances, keeping mold parting clearances strictly within 0.005mm on premium S136 stainless steel mold cavity blocks heat-treated to 52 HRC.
가압 오일 몰드 가열(결정화 제어)
To secure the proper semi-crystalline phase (giving PEEK its signature opaque beige color and stiffness), mold temperatures must be maintained continuously at 160°C–200°C (320°F to 392°F) using pressurized oil-heating controllers. Cold molds cause the melt to freeze amorphous, turning parts translucent brown and mechanically weak.
건조제 사전 건조 프로토콜
While PEEK absorbs minimal water, moisture causes hydrolytic splay and weld line degradation. We desiccant-dry PEEK 150G resin at 150°C (302°F) for 3–4 hours, keeping internal moisture below 0.02% to secure optimal molecular bonds.
Melt and Gate Optimization
Melt temperatures are strictly kept between 360°C and 400°C (680°F to 752°F) using ceramic heater bands. To prevent high shear heating and cosmetic splay near sub-millimeter gates, our engineering team optimizes hot-runner gate geometries during the DFM phase.
