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. В отличие от термопластов, these materials cure permanently under heat and pressure, Создание жесткого, stable parts ideal for diverse applications.
Two primary types dominate the industry:
- Мочевина-формальдегид (Uf) Инъекция: Рентабельный, with excellent electrical insulation properties. Common in electrical components and low-cost household items.
- Melamine-Formaldehyde (MF) Формование: Boasts high hardness, теплостойкость, and food-contact safety. Widely used for tableware, части устройства, and high-gloss surfaces.
Below is a quick comparison of key characteristics:
| Функция | Мочевина-формальдегид (Uf) | Melamine-Formaldehyde (MF) |
| Hardness | Середина (Шор d 70-80) | Высокий (Шор d 85-95) |
| Теплостойкость | До 120 ° C. | До 200 ° C. |

The Amino Resin Injection Molding Process
The process of amino resin injection combines heat, давление, and precise timing to create durable thermoset parts. В отличие от термопластического литья, it involves a permanent curing step that gives amino parts their unique properties. Ниже приведен пошаговый срыв:
- Материал подготовка: Amino resin (UF/MF) is mixed with fillers (НАПРИМЕР., alpha-cellulose, glass fibers) and pigments (for pigmentable amino grades) to form a homogeneous compound.
- Инъекция: The compound is injected into a heated mold at high pressure (injection pressure amino: 1000-2500 бар) to fill all cavities.
- Выклятый: The mold is held at a specific temperature (mold temperature amino: 150-200° C.) for a set time (curing time amino: 30-120 секунды) to allow the resin to cure and harden.
- Дегазация: А degassing amino mold system removes trapped air, preventing bubbles and ensuring smooth surfaces.
- Демольд: Вылеченная часть удаляется из формы. Для сложных частей, Мы используем compression-injection hybrid technology to improve mold filling and reduce defects.
Typical Thermoset Injection Cycle Times
| Part Complexity | Время цикла (Секунды) | Время лечения (Секунды) |
| Простой (НАПРИМЕР., кнопки) | 40-60 | 30-45 |
| Середина (НАПРИМЕР., ручки прибора) | 60-90 | 45-70 |
| Сложный (НАПРИМЕР., electrical switchgear) | 90-150 | 70-120 |
