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 diferencia de los termoplásticos, these materials cure permanently under heat and pressure, creando rígido, stable parts ideal for diverse applications.
Two primary types dominate the industry:
- Urea-formaldehído (UF) Inyección: Rentable, with excellent electrical insulation properties. Common in electrical components and low-cost household items.
- Melamine-Formaldehyde (Mf) Moldura: Boasts high hardness, resistencia al calor, and food-contact safety. Widely used for tableware, piezas de electrodomésticos, and high-gloss surfaces.
Below is a quick comparison of key characteristics:
| Característica | Urea-formaldehído (UF) | Melamine-Formaldehyde (Mf) |
| Hardness | Medio (Orilla D 70-80) | Alto (Orilla D 85-95) |
| Resistencia al calor | Hasta 120 ° C | Hasta 200 ° C |
| Food-Contact Safe | No | Sí (Grados aprobados por la FDA) |
| Aislamiento eléctrico | Excelente | Muy bien |
| Cost | Low to Medium | Medium to High |
| Usos comunes | Aparejo eléctrico, closure caps | Vajilla, perillas, toilet seats |

The Amino Resin Injection Molding Process
The process of amino resin injection combines heat, presión, and precise timing to create durable thermoset parts. A diferencia de la moldura termoplástica, it involves a permanent curing step that gives amino parts their unique properties. A continuación se muestra un desglose paso a paso:
- Preparación de material: Amino resin (UF/MF) is mixed with fillers (P.EJ., alpha-cellulose, glass fibers) and pigments (for pigmentable amino grades) to form a homogeneous compound.
- Inyección: The compound is injected into a heated mold at high pressure (injection pressure amino: 1000-2500 bar) to fill all cavities.
- Curación: The mold is held at a specific temperature (mold temperature amino: 150-200° C) for a set time (curing time amino: 30-120 artículos de segunda clase) to allow the resin to cure and harden.
- Desgásico: A degassing amino mold system removes trapped air, preventing bubbles and ensuring smooth surfaces.
- Fundamento: La parte curada se retira del molde. Para piezas complejas, Usamos compression-injection hybrid technology to improve mold filling and reduce defects.
Typical Thermoset Injection Cycle Times
| Part Complexity | Tiempo de ciclo (Artículos de segunda clase) | Tiempo de curado (Artículos de segunda clase) |
| Simple (P.EJ., botones) | 40-60 | 30-45 |
| Medio (P.EJ., perillas) | 60-90 | 45-70 |
| Complejo (P.EJ., electrical switchgear) | 90-150 | 70-120 |
