Процесс: Step-by-Step LCP Injection Molding

LCP’s unique thermotropic mesomorphic behavior and ultra-low viscosity require a highly controlled injection molding process. Even minor deviations in temperature, скорость, or pressure can compromise part precision or cause defects like weld lines. Below is our optimized process, designed to maximize consistency and performance:​

Шаг 1: Материал подготовка (Сушка)​

LCP absorbs minimal moisture (0.02% максимум), but even trace amounts cause surface defects (НАПРИМЕР., splay). We dry LCP pellets in a dehumidifying dryer at 150 ° C для 4 часы (target moisture content: <0.01%). For halogen-free or medical-grade LCP, we use nitrogen-purged dryers to prevent contamination.​

Шаг 2: Дизайн плесени & Preparation​

• Hot-Runner Optimization: We use multi-cavity hot runners with balanced flow channels to ensure uniform LCP distribution—critical for high-cavitation up to 128-fold формы. Gates are placed to minimize weld lines (a common LCP defect).​

• Контроль температуры формы: Molds are heated to 100–140 °C (via electric heaters) to promote LCP’s liquid-crystal orientation, which enhances part strength and dimensional stability. Для тонкостенных деталей, we use conformal cooling to avoid uneven cooling.​

Шаг 3: Настройка машины

• Barrel Temperature Profile: Barrel zones are set to a precise gradient to melt LCP without degradation:​

• Feed zone: 320 ° C. (softens pellets)​

• Melt zone: 340–350 °C (maintains mesophase flow)​

• Nozzle: 350–360 °C (prevents solidification)​

• High-Shear Screw: Our screws have shallow flights and high rotation speed (150–200 RPM) to generate shear, which enhances LCP’s flowability and orientation.​

Шаг 4: Инъекция & Packing​

• Fast Injection (1,000 мм/с): LCP’s ultra-low viscosity allows extremely fast injection—critical for filling ultra-thin-wall (0.05 мм) cavities before cooling. Slow injection causes short shots or uneven flow.​

• Low Back-Pressure: We use low back-pressure (5–10 bar) to avoid breaking LCP’s liquid-crystal structure, which preserves part strength.​

• Gate-Seal Optimization: We adjust injection pressure to ensure proper gate sealing (prevents flash, which is hard to remove from micro-parts).​

Шаг 5: Охлаждение & Демольд

Cooling time is short (5–10 s) due to LCP’s fast crystallization. We use controlled cooling to maintain dimensional accuracy—too fast, and parts warp; Слишком медленно, and cycle times increase. Demolding uses soft, precision ejectors to avoid damaging delicate features (НАПРИМЕР., 0.1 mm pitch pins in DDR5 sockets).​

Шаг 6: Пост-обработка & Контроль качества

• Post-Anneal Stress Relief: Parts are heated to 180–200 °C for 30–60 minutes to relieve internal stresses, improving dimensional stability by 25–30%.​

• Weld-Line Minimization: For parts with critical strength requirements (НАПРИМЕР., передачи), we use laser welding to reinforce weld lines.​

• Cavity-Pressure Trace: We log cavity pressure data for every part, enabling traceability and process optimization.​

Vision 100% Осмотр: All parts undergo AOI to check for defects (вспышка, короткие снимки, отклонение размеров) and ensure compliance with specs.

Материалы: Choosing the Right LCP Grade for Your Project

LCP is available in various grades, each formulated to enhance specific properties (flowability, сила, weld resistance). The right grade depends on your application’s needs—whether you require ultra-thin walls, Высокочастотная производительность, или биосовместимость. Below is a guide to the most common LCP grades we use:​

Popular LCP Grades & Their Uses​

​

​

Grade Selection Checklist​

1. Thin-Wall Requirement: Для <0.1 ММ стены (НАПРИМЕР., 5G mmWave connectors), choose high-flow grades (Vectra E130i).​

2. Высокочастотная производительность: For 5G/6G (28–90 GHz), select low-dielectric-loss grades (Sumikasuper E5008T).​

3. Medical Use: Choose halogen-free, biocompatible grades (custom formulations meeting ISO 10993).​

4. Размерная стабильность: For parts matching ceramic/metal (НАПРИМЕР., RF filters), выбирать mineral-filled LCP (CTE-matched).​

У нас есть direct Celanese & Polyplastics supply agreements, ensuring consistent access to top LCP grades—even for high-volume orders.

Преимущества: Why LCP Injection Molding Outperforms Alternatives

LCP Injection Molding offers unique advantages that make it irreplaceable for micro-scale, Высокопроизводительные приложения. Compared to PPS, Заглядывать, and ceramics, LCP delivers unmatched value for miniaturized, high-frequency, and high-heat parts:​

• Ultra-Low Viscosity: LCP’s melt viscosity is 5–10x lower than PPS/PEEK, включает в себя ultra-thin-wall parts down to 0.05 mm and 0.1 mm pitch capability (dense pin grids in connectors). No other plastic can match this for miniaturization.​

• High-Frequency Dielectric Performance: LCP has ultra-low dielectric loss (Df <0.002 в 10 GHz) и стабильная диэлектрическая проницаемость (Dk ≈3.0), making it the top choice for 5G/6G RF components (НАПРИМЕР., mmWave connectors, coax filters) that require minimal signal loss.​
• Extreme Thermal Stability: С 300 ° C HDT, LCP maintains strength in high-heat​ environments (НАПРИМЕР., automotive engine bays, 5G base station amplifiers) without warping or losing strength. This outperforms PPS (HDT: 260 ° C.) and matches PEEK (HDT: 300 ° C.) at a lower cost for non-implant applications.​
• CTE Matched to Ceramic: Mineral-filled LCP has a coefficient of thermal expansion (CTE) of 5–8 × 10⁻⁶/°C—nearly identical to ceramic substrates (6 × 10⁻⁶/° C.). This eliminates thermal stress in multi-material assemblies (НАПРИМЕР., RF filters with ceramic cores), a problem that plagues PPS/PEEK (CTE 15–20 × 10⁻⁶/°C).​

• Chemical Inertness: LCP resists oils, растворители, кислоты (PH 2–12), and bases—similar to PEEK but with better flowability. It’s also resistant to harsh cleaning agents, сделать его идеальным для медицинских устройств (НАПРИМЕР., surgical catheters) and industrial sensors.​

• Radiation Sterilizable: LCP withstands gamma radiation (25 kGy) and ethylene oxide (ETO) sterilization—critical for reusable medical tools (НАПРИМЕР., Компоненты инсулинового насоса) that need frequent disinfection. Unlike some plastics (НАПРИМЕР., ПВХ), it doesn’t become brittle after sterilization.​

• Minimal Flash: LCP’s high flow and fast solidification reduce flash (избыточный материал) к <0.01 mm—far less than PPS/PEEK. This eliminates costly post-processing (обрезка), a major advantage for high-volume micro-parts (НАПРИМЕР., 5G connectors).​

• Fast Cycle <10 с: LCP’s fast crystallization (due to its liquid-crystal structure) cuts cycle times to 5–10 seconds—2–4x faster than PPS (15–30 s) and PEEK (20–40 s). For high-volume parts (НАПРИМЕР., DDR5 sockets), this triples production output and lowers unit costs.​

Металл & Ceramic Replacement: LCP is 50–70% lighter than metal (aluminum/steel) and 30–40% lighter than ceramic. It also costs 20–30% less than ceramic for complex shapes (no sintering needed). Например, replacing metal 5G connector shells with LCP cuts weight by 60% и стоимость за 25%.

Индустрия приложений: Where LCP Injection Molding Shines

LCP Injection Molding dominates industries that demand miniaturization, Высокочастотная производительность, and reliability in harsh conditions. From 5G networks to life-saving medical devices, LCP solves problems no other material can. Below’s how key sectors leverage LCP:​

​

​

A standout example: In 5G mmWave connectors, LCP’s ability to mold 0.08 mm thin walls and maintain low dielectric loss at 90 GHz makes it the only material that can meet the industry’s miniaturization and performance goals. Ceramic connectors are too brittle, and PPS can’t handle the frequency or thinness.
