What Is Amino Resin Injection Molding?

Amino resin molding is a specialized thermoset injection molding process that uses resins derived from amino compounds (such as urea or melamine) combined with formaldehyde. A differenza dei termoplastici, these materials cure permanently under heat and pressure, Creazione di rigidi, stable parts ideal for diverse applications.​

Two primary types dominate the industry:

  • Urea-formaldeide (Uf) Iniezione: Economico, with excellent electrical insulation properties. Common in electrical components and low-cost household items.​
  • Melamine-Formaldehyde (Mf) Modanatura: Boasts high hardness, Resistenza al calore, and food-contact safety. Widely used for tableware, parti di elettrodomestici, and high-gloss surfaces.​

Below is a quick comparison of key characteristics:

The Amino Resin Injection Molding Process

The process of amino resin injection combines heat, pressione, and precise timing to create durable thermoset parts. A differenza dello stampaggio termoplastico, it involves a permanent curing step that gives amino parts their unique properties. Di seguito è riportato una rottura passo-passo:

  1. Preparazione del materiale: Amino resin (UF/MF) is mixed with fillers (PER ESEMPIO., alpha-cellulose, glass fibers) and pigments (for pigmentable amino grades) to form a homogeneous compound.​
  1. Iniezione: The compound is injected into a heated mold at high pressure (injection pressure amino: 1000-2500 sbarra) to fill all cavities.​
  1. Polimerizzazione: The mold is held at a specific temperature (mold temperature amino: 150-200° C.) for a set time (curing time amino: 30-120 Secondi) to allow the resin to cure and harden.​
  1. Degassante: UN degassing amino mold system removes trapped air, preventing bubbles and ensuring smooth surfaces.​
  1. Sformatura: La parte curata viene rimossa dallo stampo. Per parti complesse, Usiamo compression-injection hybrid technology to improve mold filling and reduce defects.​

Advantages of Amino Resin Injection Molding

Scegliere thermoset amino resin parts offers numerous benefits over other materials (PER ESEMPIO., termoplastici, metalli). Here’s why it’s a smart choice for your project:

  • Alta durezza (Mf): Melamine parts have a Shore D hardness of 85-95, making them resistant to scratches and impacts—perfect for high-use items like tableware.​
  • Resistenza al calore: Amino parts can withstand temperatures up to 200°C (Mf), making them suitable for appliance components near heat sources.​
  • Isolamento elettrico (Uf): UF resin provides excellent insulation, meeting UL standards for electrical switchgear and circuit parts.​
  • Stabilità dimensionale: Low cure shrink (meno di 1%) ensures parts retain their shape even under temperature changes or stress.​
  • Cost-Effective Thermoset: Compared to other thermosets (PER ESEMPIO., epossidico), amino resins offer lower material and production costs for high-volume runs.​

Flame-Retardant Amino: Most grades are naturally flame-retardant, reducing the need for additional additives.
