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. Ao contrário dos termoplásticos, these materials cure permanently under heat and pressure, criando rígido, stable parts ideal for diverse applications.
Two primary types dominate the industry:
- Urerea-formaldeído (Uf) Injeção: Econômico, with excellent electrical insulation properties. Common in electrical components and low-cost household items.
- Melamine-Formaldehyde (MF) Moldagem: Boasts high hardness, Resistência ao calor, and food-contact safety. Widely used for tableware, peças do aparelho, and high-gloss surfaces.
Below is a quick comparison of key characteristics:
Recurso | Urerea-formaldeído (Uf) | Melamine-Formaldehyde (MF) |
Hardness | Médio (Costa d 70-80) | Alto (Costa d 85-95) |
Resistência ao calor | Até 120 ° C. | Até 200 ° C. |
Food-Contact Safe | No | Sim (Notas aprovadas pela FDA) |
Isolamento elétrico | Excelente | Muito bom |
Cost | Low to Medium | Medium to High |
Usos comuns | Equipamento elétrico, closure caps | Tableware, Appliance Knobs, toilet seats |

The Amino Resin Injection Molding Process
The process of amino resin injection combines heat, pressão, and precise timing to create durable thermoset parts. Ao contrário da moldagem termoplástica, it involves a permanent curing step that gives amino parts their unique properties. Abaixo está um colapso passo a passo:
- Preparação do material: Amino resin (UF/MF) is mixed with fillers (Por exemplo, alpha-cellulose, glass fibers) and pigments (for pigmentable amino grades) to form a homogeneous compound.
- Injeção: The compound is injected into a heated mold at high pressure (injection pressure amino: 1000-2500 bar) to fill all cavities.
- Cura: The mold is held at a specific temperature (mold temperature amino: 150-200° c) for a set time (curing time amino: 30-120 segundos) to allow the resin to cure and harden.
- Desgaseificação: UM degassing amino mold system removes trapped air, preventing bubbles and ensuring smooth surfaces.
- Desmoldagem: A parte curada é removida do molde. Para peças complexas, nós usamos compression-injection hybrid technology to improve mold filling and reduce defects.
Typical Thermoset Injection Cycle Times
Part Complexity | Tempo de ciclo (Segundos) | Tempo de cura (Segundos) |
Simples (Por exemplo, botões) | 40-60 | 30-45 |
Médio (Por exemplo, Appliance Knobs) | 60-90 | 45-70 |
Complexo (Por exemplo, electrical switchgear) | 90-150 | 70-120 |

Advantages of Amino Resin Injection Molding
Escolhendo thermoset amino resin parts offers numerous benefits over other materials (Por exemplo, Termoplásticos, metais). Here’s why it’s a smart choice for your project:
- Alta dureza (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.
- Resistência ao calor: Amino parts can withstand temperatures up to 200°C (MF), making them suitable for appliance components near heat sources.
- Isolamento elétrico (Uf): UF resin provides excellent insulation, meeting UL standards for electrical switchgear and circuit parts.
- Estabilidade dimensional: Low cure shrink (menor que 1%) ensures parts retain their shape even under temperature changes or stress.
- Cost-Effective Thermoset: Compared to other thermosets (Por exemplo, epóxi), 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.
