What Is PEBA Injection Molding?
Polyether Block Amide (ПЕБА) Инъекционное формование is a specialized manufacturing process that shapes PEBA thermoplastic elastomer—a unique flexible block copolymer—into custom parts via high-pressure injection into precision molds. Unlike rigid plastics or traditional rubbers, PEBA blends the elasticity of elastomers with the processability of thermoplastics, making it ideal for applications requiring both flexibility and structural integrity.
По своей сути, PEBA plastic molding leverages the material’s segmented structure: hard polyamide (А) blocks provide strength and chemical resistance, while soft polyether (Финиш) blocks deliver flexibility and low-temperature toughness. This balance explains why PEBA is the material of choice for industries ranging from medical to sports equipment.

The PEBA Injection Molding Process: Step-by-Step Excellence
Achieving consistent PEBA parts requires strict control over every process step—from resin preparation to final degating. Below is our optimized workflow, designed to minimize waste and maximize part quality.
Шаг 1: Resin Drying & Preparation
PEBA absorbs moisture easily, which can cause bubbles or defects in molded parts. We dry PEBA resin grades at 80–100°C for 4–6 hours (в зависимости от оценки) using desiccant dryers to ensure moisture content <0.05%. Pigmented PEBA pellets or modified formulations (НАПРИМЕР., anti-static or radiopaque) are blended uniformly to maintain color/property consistency.
Шаг 2: Расплавлять температуру & Screw Design
А PEBA melt temperature window имеет решающее значение: Слишком низко, and the resin won’t flow evenly; Слишком высоко, and it degrades. We target 190–240°C (adjusted by grade) and use specialized screws with:
- Deep feed zones to prevent shear heating
- Low-compression ratios (1.5:1 к 2:1) to avoid polymer breakdown
- Smooth barrel surfaces to reduce friction (критическое для low-shear molding)
Шаг 3: Инъекция & Mold Filling
Resin is injected into the mold at pressures of 800–1,200 bar, with injection speeds tailored to part thickness (slower for thin walls to avoid jetting). Наш in-mold cooling systems use precision water channels to control temperature (typically 30–40°C) and reduce PEBA molding cycle time—we average 15–45 seconds per cycle (varies by part size).
Шаг 4: Демольд & Degating
After cooling, parts are demolded gently to avoid warping. We use automated PEBA degating techniques (НАПРИМЕР., laser cutting or punch tools) to remove runners cleanly, обеспечение гладкого, burr-free edges—critical for medical and electronic applications.
Шаг 5: Качественная проверка
Каждая партия подвергается 100% Проверки размеров (via CMM machines) and material property testing (предел прочности, удлинение, rebound). Для медицинских деталей, we also conduct biocompatibility and FDA compliance audits.

Тематическое исследование: How We Solved a Medical Device Client’s Kink Problem
A leading medical device manufacturer approached us with a critical issue: their existing IV tube (made from PVC) kinked easily, disrupting fluid flow and risking patient safety. They needed a kink-resistant IV tube that was also biocompatible and sterilizable.
Наше решение:
- Выбор материала: Recommended a USP Class VI biocompatible PEBA grade with high flexural modulus (200 МПА) for kink resistance.
- Дизайн плесени: Used gas-assist molding to create a reinforced tube wall (0.8 мм толщиной) with a smooth inner diameter (ИДЕНТИФИКАТОР) for unobstructed flow.
- Управление процессом: Оптимизированный in-mold cooling to reduce cycle time from 60 к 35 секунды, enabling high-volume production.
Результаты:
- The PEBA IV tube withstood 10,000 bending cycles without kinking (против. 500 cycles for PVC).
- Met FDA and ISO 10993 requirements for biocompatibility.
Reduced the client’s production costs by 18% (via faster cycles and lower material waste).
