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. Im Gegensatz zu Thermoplastik, these materials cure permanently under heat and pressure, starr erstellen, stable parts ideal for diverse applications.
Two primary types dominate the industry:
- Harnstoff-Formaldehyd (Uf) Injektion: Kostengünstig, with excellent electrical insulation properties. Common in electrical components and low-cost household items.
- Melamine-Formaldehyde (MF) Formen: Boasts high hardness, Wärmewiderstand, and food-contact safety. Widely used for tableware, Geräte -Teile, and high-gloss surfaces.
Below is a quick comparison of key characteristics:
Feature | Harnstoff-Formaldehyd (Uf) | Melamine-Formaldehyde (MF) |
Hardness | Medium (Ufer d 70-80) | Hoch (Ufer d 85-95) |
Wärmewiderstand | Bis zu 120 ° C. | Bis zu 200 ° C. |
Food-Contact Safe | No | Ja (Von der FDA zugelassene Noten) |
Elektrische Isolierung | Ausgezeichnet | Sehr gut |
Cost | Low to Medium | Medium to High |
Gemeinsame Verwendungen | Elektrische Schaltanlage, closure caps | Geschirr, Geräteknöpfe, toilet seats |

The Amino Resin Injection Molding Process
The process of amino resin injection combines heat, Druck, and precise timing to create durable thermoset parts. Im Gegensatz zu thermoplastischen Formteilen, it involves a permanent curing step that gives amino parts their unique properties. Unten finden Sie eine Schritt-für-Schritt-Aufschlüsselung:
- Materialvorbereitung: Amino resin (UF/MF) is mixed with fillers (Z.B., alpha-cellulose, glass fibers) and pigments (for pigmentable amino grades) to form a homogeneous compound.
- Injektion: The compound is injected into a heated mold at high pressure (injection pressure amino: 1000-2500 Bar) to fill all cavities.
- Heilung: The mold is held at a specific temperature (mold temperature amino: 150-200° C) for a set time (curing time amino: 30-120 Sekunden) to allow the resin to cure and harden.
- Degasieren: A degassing amino mold system removes trapped air, preventing bubbles and ensuring smooth surfaces.
- Entformen: Der geheilte Teil wird aus der Form entfernt. Für komplexe Teile, Wir verwenden compression-injection hybrid technology to improve mold filling and reduce defects.
Typical Thermoset Injection Cycle Times
Part Complexity | Zykluszeit (Sekunden) | Härtungszeit (Sekunden) |
Einfach (Z.B., Knöpfe) | 40-60 | 30-45 |
Medium (Z.B., Geräteknöpfe) | 60-90 | 45-70 |
Komplex (Z.B., electrical switchgear) | 90-150 | 70-120 |

Advantages of Amino Resin Injection Molding
Wählen thermoset amino resin parts offers numerous benefits over other materials (Z.B., Thermoplastik, Metalle). Here’s why it’s a smart choice for your project:
- Hohe Härte (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.
- Wärmewiderstand: Amino parts can withstand temperatures up to 200°C (MF), making them suitable for appliance components near heat sources.
- Elektrische Isolierung (Uf): UF resin provides excellent insulation, meeting UL standards for electrical switchgear and circuit parts.
- Dimensionsstabilität: Low cure shrink (Weniger als 1%) ensures parts retain their shape even under temperature changes or stress.
- Cost-Effective Thermoset: Compared to other thermosets (Z.B., Epoxid), 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.
