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. Contrairement aux thermoplastiques, these materials cure permanently under heat and pressure, Création de rigides, stable parts ideal for diverse applications.
Two primary types dominate the industry:
- Urée-formaldéhyde (Uf) Injection: Rentable, with excellent electrical insulation properties. Common in electrical components and low-cost household items.
- Melamine-Formaldehyde (MF) Moulage: Boasts high hardness, résistance à la chaleur, and food-contact safety. Widely used for tableware, pièces de l'appareil, and high-gloss surfaces.
Below is a quick comparison of key characteristics:
Caractéristique | Urée-formaldéhyde (Uf) | Melamine-Formaldehyde (MF) |
Hardness | Moyen (Rive D 70-80) | Haut (Rive D 85-95) |
Résistance à la chaleur | Jusqu'à 120 ° C | Jusqu'à 200 ° C |
Food-Contact Safe | No | Oui (Grades approuvés par la FDA) |

The Amino Resin Injection Molding Process
The process of amino resin injection combines heat, pression, and precise timing to create durable thermoset parts. Contrairement à la moulure thermoplastique, it involves a permanent curing step that gives amino parts their unique properties. Ci-dessous est une ventilation étape par étape:
- Préparation des matériaux: Amino resin (UF/MF) is mixed with fillers (Par exemple, alpha-cellulose, glass fibers) and pigments (for pigmentable amino grades) to form a homogeneous compound.
- Injection: The compound is injected into a heated mold at high pressure (injection pressure amino: 1000-2500 bar) to fill all cavities.
- Durcissement: The mold is held at a specific temperature (mold temperature amino: 150-200° C) for a set time (curing time amino: 30-120 secondes) to allow the resin to cure and harden.
- Dégazage: UN degassing amino mold system removes trapped air, preventing bubbles and ensuring smooth surfaces.
- Démêlé: La partie durcie est retirée du moule. Pour des pièces complexes, Nous utilisons compression-injection hybrid technology to improve mold filling and reduce defects.
Typical Thermoset Injection Cycle Times
Part Complexity | Temps de cycle (Secondes) | Temps de durcissement (Secondes) |
Simple (Par exemple, boutons) | 40-60 | 30-45 |
Moyen (Par exemple, Boutons d'appareil) | 60-90 | 45-70 |
Complexe (Par exemple, electrical switchgear) | 90-150 | 70-120 |
