What Is Polyethylene (Pe) Injektionsformung?
Polyethylen (Pe) is a thermoplastic polymer derived from ethylene monomers, celebrated for its versatility, niedrige Kosten, and excellent chemical resistance. Injektionsformung is a manufacturing process where molten plastic is injected into a mold cavity, abgekühlt, and ejected as a finished part. Zusammen, PE injection molding creates high-quality, consistent components for countless industries.
Schlüsseldefinitionen & Prozessübersicht
| Begriff | Definition |
| Polyethylen (Pe) | Ein leichtes Gewicht, flexible thermoplastic with high impact strength and resistance to chemicals/water. |
| Injektionsformung | A high-volume process: plastic pellets → melted → injected into mold → cooled → demolded. |
| Schimmelpilzhöhle | 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. Im Folgenden finden Sie die kritischsten Merkmale für Hersteller und Käufer:

The PE Injection Molding Process: Schritt-für-Schritt-Exzellenz
Ein glatt, well-managed process is key to producing high-quality PE parts. Our process follows five core stages, each optimized for PE’s unique properties.
Schritt 1: Materialvorbereitung
- Pelletauswahl: Choose the right PE grade (Z.B., HDPE für Starrheit, LDPE for flexibility) and add Zusatzstoffe (UV -Stabilisatoren, Farbtöne, or flame retardants) nach Bedarf.
- Trocknen: 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.
Schritt 2: Schimmeldesign
- Zusammenarbeit: Our engineers work with you to design molds that account for PE’s shrinkage rate (1.5–5 %, higher than ABS).
- Kühlsystem: Molds include precision cooling channels to ensure uniform cooling (critical for PE’s low melting point).
- Prototyp -Test: We 3D-print mold prototypes first to validate design before full production (saves time and cost).
Schritt 3: Setting Injection Parameters
PE’s low viscosity requires careful parameter tuning to avoid defects (Z.B., flash or warping). Below are our standard parameters for HDPE (the most common PE grade):
| Parameter | Ideal Range for HDPE | Zweck |
| Lauftemperatur | 160–220 ° C. | Ensures PE melts evenly without degradation. |
| Injektionsdruck | 50–120 MPa | Füllt Schimmelhöhlen vollständig (Kritisch für dünnwandige Teile). |
| Kühlzeit | 10–30 Sekunden | Verhindert Warping; balances speed and quality. |
Schritt 4: Nachbereitungsvorgänge
Nach dem Ermachung, parts may undergo:
- Trimmen: Entfernen von überschüssigem Kunststoff (Blitz) with automated tools.
- Montage: Joining parts via welding or adhesives (for complex components).
Inspektion: Final QC checks for dimensional accuracy and surface quality.
Materialien: 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 recycelte Optionen.
Types of PE for Injection Molding
| PE -Typ | Key Traits | Gemeinsame Anwendungen |
| Low-Density PE (LDPE) | Flexibel, weich, good impact resistance. | Konsumgüter (Spielzeug, Flaschen drücken), packaging films. |
| High-Density PE (HDPE) | Starr, stark, high chemical resistance. | Kfz -Teile (Kraftstofftanks), Medizinprodukte (Spritzenfässer), Verpackung (caps, Behälter). |
| Linear Low-Density PE (Llde) | Stretchable, pünktlich-resistent, more durable than LDPE. | Agricultural films, flexible packaging (Taschen), sports equipment. |
Tipps zur Materialauswahl
- Prioritize performance: For chemical exposure (Z.B., Medizinprodukte), choose HDPE. For flexibility (Z.B., Spielzeug), pick LDPE.
- Consider cost: LDPE is the most affordable; HDPE costs slightly more but offers better durability.
Nachhaltigkeit umarmen: Unser recycled PE (rPE) is made from post-consumer waste and meets 80% of the performance of virgin PE—ideal for eco-friendly brands.
Oberflächenbehandlung: Verbesserung der Ästhetik & Funktionalität
PE’s natural surface is smooth but can be modified to improve appearance, Griff, or compatibility with other materials. We offer four core surface treatments:
| Behandlung | Prozess | Vorteile |
| Oberflächenbearbeitung | Polishing or sandblasting to remove imperfections (Z.B., Kratzer). | Creates a sleek, Professioneller Look; improves paint adhesion. |
| Texturierung | Hinzufügen von Mustern (Z.B., matt, Rippen) to the mold cavity. | Verstärkt den Griff (für Werkzeuge, Griffe) oder versteckt Fingerabdrücke (Konsumgüter). |
| Beschichtung | Eine dünne Schicht auftragen (Z.B., Polyurethan) to the part surface. | Boosts chemical resistance (für medizinische Teile) oder UV -Schutz (outdoor components). |
| Painting/Printing | Spray-painting or pad-printing logos/colors. | Improves branding (Z.B., automotive parts with company logos) oder Ästhetik (Spielzeug). |
