What Is Polyethylene (Финиш) Инъекционное формование?
Полиэтилен (Финиш) is a thermoplastic polymer derived from ethylene monomers, celebrated for its versatility, бюджетный, and excellent chemical resistance. Инъекционное формование is a manufacturing process where molten plastic is injected into a mold cavity, охлажденный, and ejected as a finished part. Вместе, PE injection molding creates high-quality, consistent components for countless industries.
Key Definitions & Process Overview
| Термин | Определение |
| Полиэтилен (Финиш) | Легкий, flexible thermoplastic with high impact strength and resistance to chemicals/water. |
| Инъекционное формование | A high-volume process: plastic pellets → melted → injected into mold → cooled → demolded. |
| Mold Cavity | The hollow space in a mold that shapes the final PE part (can be single or multi-cavity for mass production). |
Core Material Properties of PE
PE’s unique properties make it ideal for injection molding. Below are the most critical traits for manufacturers and buyers:
- Плотность: Ranges from 0.910–0.965 g/cm³ (low-density LDPE to high-density HDPE).
- Точка плавления: 105–135 ° C. (lower than many plastics, reducing energy costs in molding).
- Химическая устойчивость: Impervious to acids, спирты, и вода (critical for medical and packaging applications).
- Воздействие сила: Remains flexible even at low temperatures (ideal for automotive and consumer goods).
Переработка: Most PE grades are 100% переработана, Согласно целям устойчивости.

The PE Injection Molding Process: Step-by-Step Excellence
Гладкий, well-managed process is key to producing high-quality PE parts. Our process follows five core stages, each optimized for PE’s unique properties.
Шаг 1: Материал подготовка
- Pellet Selection: Choose the right PE grade (НАПРИМЕР., HDPE для жесткости, LDPE for flexibility) and add добавки (УФ -стабилизаторы, цветовые средства, or flame retardants) по мере необходимости.
- Сушка: While PE is moisture-resistant, we pre-dry pellets at 60–80°C for 2–4 hours to remove any surface moisture (prevents bubbles in final parts).
- Feeding: Pellets are fed into the injection machine’s hopper, where they move to the heating barrel.
Шаг 2: Mold Design
- Сотрудничество: Our engineers work with you to design molds that account for PE’s shrinkage rate (1.5–5%, higher than ABS).
- Система охлаждения: Molds include precision cooling channels to ensure uniform cooling (critical for PE’s low melting point).
- Prototype Testing: We 3D-print mold prototypes first to validate design before full production (saves time and cost).
Шаг 3: Setting Injection Parameters
PE’s low viscosity requires careful parameter tuning to avoid defects (НАПРИМЕР., flash or warping). Below are our standard parameters for HDPE (the most common PE grade):
| Параметр | Ideal Range for HDPE | Цель |
| Barrel Temperature | 160–220 ° C. | Ensures PE melts evenly without degradation. |
| Давление впрыска | 50–120 MPa | Fills mold cavities completely (critical for thin-walled parts). |
| Время охлаждения | 10–30 секунд | Prevents warping; balances speed and quality. |
Шаг 4: Post-Molding Operations
After demolding, parts may undergo:
- Обрезка: Удаление лишнего пластика (вспышка) with automated tools.
- Сборка: Joining parts via welding or adhesives (for complex components).
Осмотр: Final QC checks for dimensional accuracy and surface quality.
Материалы: Choosing the Right PE for Your Project
Not all PE is the same—selecting the right grade ensures your parts meet performance and cost goals. We offer a full range of PE materials, plus recycled options.
Types of PE for Injection Molding
| PE Тип | Key Traits | Общие приложения |
| Low-Density PE (LDPE) | Гибкий, мягкий, good impact resistance. | Потребительские товары (игрушки, сжимать бутылки), packaging films. |
| High-Density PE (HDPE) | Жесткий, сильный, high chemical resistance. | Автомобильные детали (топливные баки), медицинские устройства (шприц -бочки), упаковка (caps, контейнеры). |
| Linear Low-Density PE (Llde) | Stretchable, Устойчивый к проколам, more durable than LDPE. | Agricultural films, flexible packaging (мешки), sports equipment. |
Material Selection Tips
- Prioritize performance: For chemical exposure (НАПРИМЕР., медицинские устройства), choose HDPE. For flexibility (НАПРИМЕР., игрушки), pick LDPE.
- Consider cost: LDPE is the most affordable; HDPE costs slightly more but offers better durability.
Embrace sustainability: Наш recycled PE (rPE) is made from post-consumer waste and meets 80% of the performance of virgin PE—ideal for eco-friendly brands.
