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. Ao contrário dos termoplásticos, UF resin cures permanently under heat and pressure, forming rigid, dimensionally stable parts. Se enquadra na categoria mais ampla deamino-plastic injection, known for its balance of affordability and performance.
Key defining traits of this process:
- Thermoset Nature: Uma vez curado, UF parts cannot be melted or reshaped, ensuring long-term stability in harsh conditions.
- Aplicações principais: Dominant in sectors requiring electrical insulation and cost-efficiency, such as electronics and household goods.
- Versatilidade material: Blends with fillers (Por exemplo, alpha-cellulose, glass fibers) to enhance strength or reduce costs.
Below is a breakdown of core terms to clarifyUF definition molding:
| Prazo | Descrição |
|---|---|
| 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. |
| UF Plastic Molding | A casual term for UF resin injection molding, emphasizing the plastic-like final part. |

The Urea Formaldehyde Injection Molding Process
OUF 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.
A quebra passo a passo do processo
- Preparação do material: Mistura urea formaldehyde resin (granular or powder) with fillers (Por exemplo, alpha-cellulose filled UF) and pigments (for pigmentable urea resin) to create a homogeneous compound.
- Injeção: Feed the compound into a heated barrel, then inject it into a mold at high pressure (1500-2800 bar) e temperatura (160-190° c).
- Cura: Hold the mold closed to allow urea formaldehyde curing—typically 20-60 segundos (cure time UF) at 170-185°C (UF mold temperature).
- Desgaseificação: Use um degassing urea mold system to remove trapped air, preventing bubbles in parts like electrical housings.
- Desmoldagem: Eject the cured part. Para designs complexos (Por exemplo, snap-fit connectors), nós usamos BMC-UF compression-injection hybrid technology to improve mold filling.
- Pós-processamento: Opcional post-cure urea (120° C para 30 minutos) para melhorar a dureza, or secondary ops like drilling or printing.
Key Thermoset Injection Parameters for UF
| Parâmetro | Faixa típica | Impacto na qualidade da peça |
|---|---|---|
| UF Mold Temperature | 160-190° c | Higher temps speed curing; lower temps reduce shrinkage |
| Clamp Pressure UF | 1500-2800 bar | Ensures full mold filling (critical for tight tolerances) |
| Cure Time UF | 20-60 segundos | Shorter times boost output; longer times improve strength |
| Injection Speed | 50-100 mm/s | Faster speeds reduce cycle time; slower speeds prevent flash |
