Наш rapid tooling change способность (под 4 часы) also ensures flexibility—whether you need small-batch prototypes or large-volume production runs, we adapt quickly without sacrificing quality.

Процесс: Step-by-Step PEEK Injection Molding

PEEK’s unique properties require a highly controlled injection molding process—even minor deviations in temperature or pressure can compromise part quality. Below is our optimized PEEK molding cycle, designed to maximize consistency and performance:​

Шаг 1: Материал подготовка (Сушка)​

PEEK is hygroscopic (Поглощает влагу), which causes bubbling and voids in finished parts. We dry PEEK pellets in a dehumidifying dryer at 150 ° C для 4 часы (critical for maintaining material integrity). For medical-grade PEEK, we use nitrogen-purged dryers to prevent contamination.​

Шаг 2: Дизайн плесени & Preparation​

• Ворота & Runner Design: We use hot runners (instead of cold runners) to minimize PEEK waste (hot runners keep material molten, reducing scrap by 25–30%). Gates are placed to avoid shear stress (PEEK is sensitive to excessive shear, which degrades its strength).​

• Контроль температуры формы: Molds are heated to 150–200 ° C. (via oil or electric heaters) to promote uniform crystallization—this ensures размерная стабильность and prevents warping. Для толстых частей, we use gradient heating (warmer at the core, cooler at the surface).​

Шаг 3: Injection Molding Machine Setup​

• High-Heat Barrel Settings: Barrel zones are set to a temperature gradient (feed zone: 360 ° C.; melt zone: 380–400 ° C.; сопло: 390–410 °C) to melt PEEK without thermal degradation.​

• Inert-Gas Venting: We purge the mold cavity with nitrogen during injection to remove air (PEEK’s high viscosity traps air easily, leading to defects). This step is mandatory for parts like semiconductor clamps (where even tiny voids cause failure).​

Шаг 4: Инъекция & Packing​

• Injection Speed: Slow to moderate (50–100 мм/с) to control shear (excessive shear reduces PEEK’s tensile strength by 10–15%).​

• Packing Pressure: 80–90% of injection pressure, held for 10–20 seconds to compensate for shrinkage (PEEK shrinks 1.5–2.5% during cooling).​

Шаг 5: Охлаждение & Демольд

Время охлаждения варьируется в зависимости от толщины части (10 seconds for thin parts, 60 seconds for thick sections). We use controlled cooling to maintain crystallinity (цель: 35–40% for most applications; higher for structural parts, lower for flexible components). Demolding is done with gentle ejectors to avoid scratching (критическое для медицинских имплантатов).​

Шаг 6: Пост-обработка & Контроль качества

• Отжиг: Parts are heated to 180–200 °C for 1–2 hours, затем медленно охлаждался (5 ° C/мин) to relieve internal stresses. This step improves dimensional stability by 20–25%.​

• SPC Monitoring: We use Statistical Process Control (Спк) to track key parameters (температура, давление, Время цикла) в реальном времени. Any deviation beyond ±2% triggers an alert, обеспечение последовательного качества.

Осмотр: Parts undergo dimensional testing (ШМ), mechanical testing (tensile strength per ASTM D638), и визуальный осмотр (for defects like flash or voids).

Материалы: Choosing the Right PEEK Grade for Your Project

PEEK is available in various grades, each formulated to enhance specific properties (сила, износостойкость, Биосовместимость). The right grade depends on your application’s unique demands. Below is a guide to the most common PEEK grades we use:​

Popular PEEK Grades & Their Uses​

​

​

Grade Selection Checklist​

1. Temperature Requirement: If parts face >240 °C (НАПРИМЕР., Компоненты двигателя), choose glass/carbon-filled grades (they retain strength at high heat).​

2. Биосовместимость: For medical use, выбирать Implantable PEEK-OPTIMA (встречает ISO 10993) or FDA food-contact grades (НАПРИМЕР., Vestakeep MED).​

3. Износостойкость: Для движущихся частей (НАПРИМЕР., подшипники), pick carbon-filled or bearing-grade PEEK (НАПРИМЕР., Ketaspire KT-220).​

4. Flame Safety: Для электроники, ensure the grade meets UL 94 V.-0 (all standard PEEK grades qualify).​

We maintain global supply contracts with Victrex, Солвей, and Evonik, ensuring consistent access to high-quality PEEK—even for high-volume orders.

Поверхностная обработка: Улучшение производительности Peek Part

PEEK’s inherent properties are exceptional, но Поверхностная обработка can further expand its capabilities—whether you need better adhesion, Биосовместимость, или износостойкость. Below are the most effective surface treatments for PEEK parts:​

​

​

Например, Мы используем Ti-coating PEEK for dental implants to make them visible on X-rays (PEEK is radiolucent) and improve long-term stability in the jawbone. For semiconductor parts, полировка (Раствор <0.1 мкм) ensures no particle buildup on critical surfaces.

Преимущества: Why PEEK Injection Molding Outperforms Alternatives

PEEK Injection Molding offers a unique set of advantages that make it irreplaceable in critical applications. Compared to metals (сталь, алюминий) and other plastics (А, Ппс), PEEK delivers unmatched value:​

Key Advantages of PEEK​

• Extreme Temperature Resistance: PEEK maintains 90% of its strength at 240 ° C. (непрерывное использование) and can withstand short-term exposure to 300 ° C.. This outperforms aluminum (loses strength at 200 ° C.) и pps (continuous use limit: 200 ° C.).​

• Chemical Inertness: Устойчив к маслам, растворители, кислоты, и базы (even concentrated sulfuric acid at room temperature). В отличие от металлов, it won’t corrode—ideal for oil & gas and chemical processing parts.​

• Steam & Radiation Sterilizable: Can undergo 1,000+ Циклы автоклав (134 ° C., 3 бар) and is resistant to gamma radiation (25 kGy). This makes it the top choice for reusable medical instruments.​

• Superior Strength-to-Weight Ratio: PEEK has a density of 1.32 G/CM³ (50% легче, чем сталь) but tensile strength comparable to aluminum. Для аэрокосмических частей, this reduces fuel consumption by 5–10%.​

• Износостойкость: Carbon-filled PEEK has a wear rate 10x lower than nylon and 2x lower than bronze—perfect for bearings and sliding components that operate without lubrication.​

• Low Outgassing: Emits minimal volatile organic compounds (Вокал) При нагревании. This meets NASA’s outgassing standards (ASTM E595), making it suitable for space applications.​

• Биосовместимость (USP Class VI): Implantable PEEK-OPTIMA is compatible with human tissue, causing no immune response. It’s used in spinal cages, модные чашки, and dental implants.​

• Размерная стабильность: Низкий коэффициент термического расширения (CTE: 3.1–5.5 × 10⁻⁵/°C) and minimal shrinkage (1.5–2,5%) ensure parts retain their shape in temperature fluctuations.​

Metal Replacement: PEEK parts cost 20–30% more upfront than metal but last 3–5x longer (Нет коррозии, меньше износа). Например, a PEEK turbine bushing replaces a steel one, сокращение затрат на техническое обслуживание 60%.

Индустрия приложений: Where PEEK Injection Molding Shines

• Испытание: A luxury electric vehicle (Эвихт) manufacturer needed a transmission gear that could withstand 15,000 Rpm (higher than traditional gas engines) without overheating or wearing out. Metal gears were too noisy and added weight (hurting EV range), while standard plastics (ПА66) melted at the gear’s operating temperature (180 ° C.).​

• Решение: Мы выбрали bearing-grade PEEK (Solvay Ketaspire KT-220) for its low friction coefficient (0.2) и тепловая стабильность (continuous use at 240 ° C.). Наш mold-flow analysis optimized the gear’s tooth geometry to reduce shear stress during molding, пока annealing post-process relieved internal stresses (preventing warping at high RPM). Мы также использовали laser texturing on gear teeth to improve lubricant retention.​

• Результат: The PEEK gear operated smoothly at 15,000 RPM для 1,000+ часы (эквивалентно 100,000+ miles of driving) with no wear. It weighed 45% меньше, чем металл, extending the EV’s range by 8 miles per charge, и уменьшенный шум передачи 12 дБ (a key luxury feature). The manufacturer scaled to 10,000 gears/month using our multi-cavity tools, с 99.9% defect rate.​

Тематическое исследование 4: Electronic Housing for Semiconductor (260 °C Solder Bath Resistance)​

• Испытание: A semiconductor equipment maker needed a housing for wafer-handling robots that could survive 260 °C solder bath exposure (during maintenance) and had ultra-low outgassing (to avoid contaminating wafers). Metal housings were too heavy and conducted heat (risking wafer damage), while PPS housings warped at 220 °C.​

• Решение: Мы использовали general-purpose PEEK (Victrex 450G) for its thermal resistance and low outgassing (meets ASTM E595). Наш полировка (Раствор <0.1 мкм) process created a mirror-smooth surface that prevented particle buildup, и in-house mold-flow analysis designed the housing with thin, uniform walls (avoiding hot spots during molding). Мы также добавили Ультраляционное покрытие to protect against cleanroom lighting.​
