What Is Melamine Formaldehyde Resin Injection Molding?
Melamine formaldehyde injection molding (souvent appelé MF resin molding) is a specialized manufacturing process for creating high-performance parts using thermosetting melamine-formaldehyde compounds. Contrairement aux thermoplastiques, melamine thermoset injection uses resins that cure permanently under heat and pressure, resulting in rigid, durable components.
À la base, le amino-melamine process combines melamine resin with reinforcing fillers (like cellulose or glass) to enhance strength and stability. Notre MF definition service simplifies this technology for clients: we break down how melamine plastic molding differs from traditional methods—focusing on its unique ability to produce parts with consistent dimensions and resistance to heat, produits chimiques, and UV light.
Termes clés dans MF molding technology inclure:
- Durcissement: The irreversible chemical reaction that hardens the resin.
- Thermodurci: A material that retains its shape after curing (unlike thermoplastics that can be reheated).
Amino Molding: The use of amino-based resins (like melamine) for high-performance applications.

The Melamine Formaldehyde Injection Molding Process
Le MF injection cycle is a precise sequence of steps, each optimized to ensure part quality. Vous trouverez ci-dessous un aperçu étape par étape, with critical thermoset MF parameters that set our process apart:
Étape 1: Préparation des matériaux
We start with high-quality powder MF compound ou granular MF molding grade résine. The material is preheated to 40–50°C to remove moisture (critical for avoiding defects).
Étape 2: Injection
The resin is injected into a heated mold at:
- Pression d'injection: 800–1,200 bar
- Température de moisissure: 150–180 ° C (notre mold temperature MF control uses digital sensors for ±2°C accuracy)
- Clamp Force: 50–500 tonnes (tailored to part size; notre clamp force melamine settings prevent flash)
Étape 3: Durcissement
Melamine formaldehyde curing is the most critical stage. Nous utilisons:
- Temps de guérir: 30–120 secondes (varie selon l'épaisseur de la pièce; notre cure time melamine optimization cuts cycle time by 15%)
- Dégazage: Degassing MF mold technology removes trapped air, ensuring void-free parts (99.9% taux sans défaut)
Étape 4: Post-traitement
Après démouloir, Les pièces peuvent subir post-cure melamine (100–120°C for 30 minutes) pour améliorer la stabilité. We also use cold-runner MF systems to reduce material waste by 20% compared to hot-runner setups.
Pour des pièces complexes, Nous offrons compression-injection MF—a hybrid process that combines injection speed with compression molding’s uniform pressure, perfect for thick-walled items like toilet seats.
