What Is Polyvinyl Chloride (PVC) Stampaggio a iniezione?
Polivinil cloruro (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. Stampaggio a iniezione is a manufacturing process that melts plastic pellets, injects the molten material into a custom mold, e lo raffredda per formare una parte finita. Insieme, PVC injection molding creates consistent, high-performance components for sectors ranging from construction to medical devices.
Definizioni chiave & Descrizione del processo
| Termine | Definizione |
| Polivinil cloruro (PVC) | A versatile thermoplastic that can be rigid or flexible, depending on additives; known for durability and flame resistance. |
| Stampaggio a iniezione | Un processo ciclico: PVC pellets → melted → injected into mold cavity → cooled → ejected (si ripete per la produzione di massa). |
| Cavità della muffa | 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, frame delle finestre) o flessibile (used for hoses, tubo medico) with plasticizers.
- Ritardo di fiamma: Naturally resistant to fire (requires no extra additives for basic flame protection).
- Resistenza chimica: Non influenzato dalla maggior parte degli acidi, alcali, e solventi (critical for industrial and medical use).
Efficienza in termini di costi: 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.
Fare un passo 1: Preparazione del materiale
- Pellet Selection: Choose between rigid PVC (no plasticizers) or flexible PVC (with 10–40% plasticizers like phthalates).
- Additive Blending: Mix PVC pellets with additivi (stabilizers to prevent decomposition, UV inhibitors for outdoor use, coloranti).
- Asciugatura: PVC absorbs minimal moisture, but we dry pellets at 60–70°C for 1–2 hours to avoid surface defects (PER ESEMPIO., pinholes).
Fare un passo 2: Mold Design
- Compatibilità materiale: Molds for rigid PVC use cooling channels to prevent warping; molds for flexible PVC have smoother surfaces to avoid sticking.
- Prototype Testing: We 3D-print mold prototypes first to validate design—reducing costly revisions later.
Fare un passo 3: Injection Parameters (Critical for PVC)
PVC is sensitive to heat, so precise parameters are non-negotiable. Below are our standard settings for rigid PVC:
| Parametro | Ideal Range | Scopo |
| Barrel Temperature | 160–190°C | Melts PVC without decomposition (higher temps cause toxic fumes). |
| Pressione di iniezione | 80–150 MPA | Fills mold cavities completely (critical for thin-walled parts like electrical casings). |
| Tempo di raffreddamento | 20–50 seconds | Prevents warping; longer for thick rigid PVC parts. |
Fare un passo 4: Post-Molding Operations
Dopo l'espulsione, le parti subite:
- Taglio: Rimozione della plastica in eccesso (flash) with automated tools.
- Sfacciato: Smoothing sharp edges (critical for consumer products and medical devices).
Ispezione: Final checks for dimensional accuracy and surface quality.
Materiali: 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, sicurezza, and cost goals.
