What Is Urea Formaldehyde Resin Injection Molding?
Urea Formaldehyde (Uf) Resin Injection Molding is a specialized thermoset manufacturing process that uses a resin blend of urea and formaldehyde. В отличие от термопластов, UF resin cures permanently under heat and pressure, forming rigid, dimensionally stable parts. Он подпадает под более широкую категориюamino-plastic injection, known for its balance of affordability and performance.
Key defining traits of this process:
- Thermoset Nature: После вылечения, UF parts cannot be melted or reshaped, ensuring long-term stability in harsh conditions.
- Core Applications: Dominant in sectors requiring electrical insulation and cost-efficiency, such as electronics and household goods.
- Материальная универсальность: Blends with fillers (НАПРИМЕР., alpha-cellulose, glass fibers) to enhance strength or reduce costs.
Below is a breakdown of core terms to clarifyUF definition molding:
Срок | Описание |
---|---|
UF Resin Molding | The overall process of shaping urea formaldehyde resin into parts via injection. |
Thermoset UF Process | The curing-driven cycle where UF resin hardens permanently under heat/pressure. |
Urea Resin Injection | The step of forcing molten UF compound into a mold cavity at high pressure. |

The Urea Formaldehyde Injection Molding Process
АUF injection cycle is a streamlined sequence of steps that leverages heat and pressure to transform raw UF compound into finished parts. Unlike melamine-formaldehyde processes, UF molding prioritizes speed and cost-efficiency, making it ideal for high-volume applications.
Пошаговый процесс разбивки процесса
- Материал подготовка: Смешивать urea formaldehyde resin (granular or powder) with fillers (НАПРИМЕР., alpha-cellulose filled UF) and pigments (for pigmentable urea resin) to create a homogeneous compound.
- Инъекция: Feed the compound into a heated barrel, then inject it into a mold at high pressure (1500-2800 бар) и температура (160-190° C.).
- Выклятый: Hold the mold closed to allow urea formaldehyde curing—typically 20-60 секунды (cure time UF) at 170-185°C (UF mold temperature).
- Дегазация: Используйте degassing urea mold system to remove trapped air, preventing bubbles in parts like electrical housings.
- Демольд: Eject the cured part. Для сложных дизайнов (НАПРИМЕР., snap-fit connectors), Мы используем BMC-UF compression-injection hybrid technology to improve mold filling.
- Пост-обработка: Необязательный post-cure urea (120° C для 30 минуты) для повышения твердости, or secondary ops like drilling or printing.
Key Thermoset Injection Parameters for UF
Параметр | Типичный диапазон | Влияние на качество части |
---|---|---|
UF Mold Temperature | 160-190° C. | Higher temps speed curing; lower temps reduce shrinkage |
Clamp Pressure UF | 1500-2800 бар | Ensures full mold filling (critical for tight tolerances) |
Cure Time UF | 20-60 секунды | Shorter times boost output; longer times improve strength |
Injection Speed | 50-100 мм/с | Faster speeds reduce cycle time; slower speeds prevent flash |
