What Is Polyvinyl Chloride (PVC) Injektionsformung?
Polyvinylchlorid (PVC) is one of the world’s most widely used thermoplastics, composed of vinyl chloride monomers. It stands out for its adaptability—easily modified with additives to suit diverse applications. Injektionsformung ist ein Herstellungsprozess, das Plastikpellets schmilzt, injects the molten material into a custom mold, and cools it to form a finished part. Zusammen, PVC injection molding creates consistent, high-performance components for sectors ranging from construction to medical devices.
Schlüsseldefinitionen & Prozessbeschreibung
Begriff | Definition |
Polyvinylchlorid (PVC) | A versatile thermoplastic that can be rigid or flexible, depending on additives; known for durability and flame resistance. |
Injektionsformung | A cyclic process: PVC pellets → melted → injected into mold cavity → cooled → ejected (repeats for mass production). |
Schimmelpilzhöhle | The hollow space in a mold that shapes the final PVC part; can have 1–64 cavities for efficient high-volume production. |
Material Characteristics of PVC
PVC’s unique traits make it ideal for injection molding:
- Dual Form: Can be rigid (used for pipes, Fensterrahmen) oder flexibel (used for hoses, medizinischer Schlauch) with plasticizers.
- Flammenhemmung: Naturally resistant to fire (requires no extra additives for basic flame protection).
- Chemischer Widerstand: Von den meisten Säuren nicht beeinflusst, Alkalis, und Lösungsmittel (critical for industrial and medical use).
Kosteneffizienz: Raw PVC is affordable, making it a budget-friendly choice for large-scale projects.

The PVC Injection Molding Process: Step-by-Step Precision
PVC’s unique melting properties (it decomposes at high temperatures) require a carefully optimized process. Our workflow ensures consistent quality while protecting PVC’s integrity.
Schritt 1: Materialvorbereitung
- Pelletauswahl: Choose between rigid PVC (no plasticizers) or flexible PVC (with 10–40% plasticizers like phthalates).
- Additive Mischung: Mix PVC pellets with Zusatzstoffe (stabilizers to prevent decomposition, UV inhibitors for outdoor use, Farbtöne).
- Trocknen: PVC absorbs minimal moisture, but we dry pellets at 60–70°C for 1–2 hours to avoid surface defects (Z.B., pinholes).
Schritt 2: Schimmeldesign
- Materialkompatibilität: Molds for rigid PVC use cooling channels to prevent warping; molds for flexible PVC have smoother surfaces to avoid sticking.
- Prototyp -Test: We 3D-print mold prototypes first to validate design—reducing costly revisions later.
Schritt 3: Injektionsparameter (Critical for PVC)
PVC is sensitive to heat, so precise parameters are non-negotiable. Below are our standard settings for rigid PVC:
Parameter | Ideal Range | Zweck |
Lauftemperatur | 160–190°C | Melts PVC without decomposition (higher temps cause toxic fumes). |
Injektionsdruck | 80–150 MPA | Füllt Schimmelhöhlen vollständig (critical for thin-walled parts like electrical casings). |
Kühlzeit | 20–50 seconds | Verhindert Warping; longer for thick rigid PVC parts. |
Schritt 4: Nachbereitungsvorgänge
Nach Auslösen, Teile unterziehen sich:
- Trimmen: Entfernen von überschüssigem Kunststoff (Blitz) with automated tools.
- Enttäuschung: Smoothing sharp edges (critical for consumer products and medical devices).
Inspektion: Final checks for dimensional accuracy and surface quality.
Materialien: Choosing the Right PVC for Your Project
PVC’s versatility comes from its ability to be modified into different grades. Selecting the right type ensures your parts meet performance, Sicherheit, and cost goals.
Types of PVC for Injection Molding
PVC Type | Schlüsseleigenschaften | Gemeinsame Anwendungen |
Starres PVC (RPVC) | Steif, hohe Zugfestigkeit (50 MPA), excellent impact resistance. | Konstruktion (Fensterrahmen, Rohre), Kfz -Trim, electrical casings. |
Flexibler PVC (FPVC) | Bendable, elastisch (elongation up to 300%), resistant to cracking. | Medizinprodukte (Schlauch, Spritzen), Konsumgüter (Spielzeug, Schläuche), automotive gaskets. |
Foamed PVC | Leicht (Dichte: 0.6–0.8 g/cm³), sound-absorbent. | Interior design (Wandpaneele), Verpackung (Schutzeinsätze). |
Recycled PVC (rPVC) | 75–85% of the strength of virgin PVC; eco-friendly and cost-effective. | Konstruktion (Fechten, decking), non-critical consumer goods (Lagerbehälter). |
