What Is Melamine Formaldehyde Resin Injection Molding?
Melamine formaldehyde injection molding (often called MF resin molding) is a specialized manufacturing process for creating high-performance parts using thermosetting melamine-formaldehyde compounds. Ao contrário dos termoplásticos, melamine thermoset injection uses resins that cure permanently under heat and pressure, resulting in rigid, durable components.
Na sua essência, o amino-melamine process combines melamine resin with reinforcing fillers (like cellulose or glass) to enhance strength and stability. Nosso 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, produtos químicos, and UV light.
Termos -chave em MF molding technology incluir:
- Cura: The irreversible chemical reaction that hardens the resin.
- Thermoset: 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
O MF injection cycle is a precise sequence of steps, each optimized to ensure part quality. Abaixo está uma visão geral passo a passo, with critical thermoset MF parameters that set our process apart:
Etapa 1: Preparação do material
We start with high-quality powder MF compound ou granular MF molding grade resina. The material is preheated to 40–50°C to remove moisture (critical for avoiding defects).
Etapa 2: Injeção
The resin is injected into a heated mold at:
- Pressão de injeção: 800–1,200 bar
- Temperatura do molde: 150–180 ° C. (nosso mold temperature MF control uses digital sensors for ±2°C accuracy)
- Clamp Force: 50–500 toneladas (tailored to part size; nosso clamp force melamine settings prevent flash)
Etapa 3: Cura
Melamine formaldehyde curing is the most critical stage. Nós usamos:
- Cura tempo: 30–120 segundos (varia de acordo com a espessura da peça; nosso cure time melamine optimization cuts cycle time by 15%)
- Desgaseificação: Degassing MF mold technology removes trapped air, ensuring void-free parts (99.9% taxa livre de defeitos)
Etapa 4: Pós-processamento
After demolding, parts may undergo post-cure melamine (100–120°C for 30 minutos) Para aumentar a estabilidade. We also use cold-runner MF systems to reduce material waste by 20% compared to hot-runner setups.
Para peças complexas, nós oferecemos compression-injection MF—a hybrid process that combines injection speed with compression molding’s uniform pressure, perfect for thick-walled items like toilet seats.
