What Is Transparent Plastics Injection Molding?
Transparent plastic injection molding is a specialized manufacturing process focused on creating clear, light-transmitting parts using high-performance polymers. Unlike standard injection molding, which prioritizes strength or cost, optical-grade molding centers on preserving clarity, minimizing defects (like warping or weld lines), and optimizing light transmission.
Al centro, clear polymer injection transforms amorphous transparent resins (PER ESEMPIO., PC, PMMA) into precision parts via controlled heating, iniezione, e raffreddamento. Nostro transparent thermoplastic service simplifies this technology: we explain how light-transmission molding differs from conventional methods—emphasizing its focus on low shear, raffreddamento uniforme, and defect-free surfaces to produce see-through plastic parts con <1% haze and consistent optical performance.
Termini chiave in precision optic molding includere:
- Amorphous Transparent Resins: Non-crystalline polymers (PER ESEMPIO., PC, PMMA) that maintain clarity (crystalline resins like nylon become opaque).
- Low-Haze Injection: Molding processes that limit light scattering (haze <1%) for sharp, clear optics.
Optical-Grade Molding: Production meeting strict standards for light transmission (>90%) and birefringence (optical distortion <5 nm/cm).

The Transparent Plastics Injection Molding Process
IL transparent plastic injection molding process is a highly controlled sequence optimized to preserve clarity and optical performance. Below is a step-by-step overview with critical parameters:
Fare un passo 1: Preparazione del materiale
- Resin Drying: Amorphous transparent resins (PER ESEMPIO., PC, PMMA) undergo 2–4 hours of drying at 80–100°C to remove moisture (moisture causes cloudiness; critical for >90% LT).
- Gestione della resina: Stored in sealed, dry containers to prevent reabsorption before molding.
Fare un passo 2: Injection Setup
- Temperatura di scioglimento: 230–320 ° C. (material-dependent: PC = 280–320°C; PMMA = 230–260°C); precise temp control (±5°C) avoids resin degradation.
- Temperatura della muffa: 80–120 ° C. (maintained via water or oil heating); uniform temp prevents warping and ensures clear surfaces.
- Screw Design: Low-shear screw design (22:1 L/D ratio) to minimize resin shear (shear causes haze or discoloration).
Fare un passo 3: Iniezione & Monitoring
- Hot-Runner Valve Gate: Precise flow control; maintains melt temp to avoid cold spots (cold spots create opaque areas).
- Vacuum Venting: Removes trapped air (air bubbles cause clarity defects); reduces scrap rate by 90%.
- Injection Strategy: Slow-fill high-pack (fill speed = 20–30 mm/s; pack pressure = 800–1,000 bar) per evitare turbolenze (turbulence scatters light).
Fare un passo 4: Raffreddamento & Post-Molding
- Raffreddamento uniforme: Coolant flow rate optimized (2–3 L/min) to ensure even cooling; prevents stress-induced birefringence.
- Stress-Relief Anneal: 1–2 hours at 80–100°C (for PC/PMMA) Per ridurre lo stress interno; critico per precision optic molding.
In-Mold Coating: Optional clear protective coating applied during molding (PER ESEMPIO., anti-scratch HC coating); Risparmia i tempi di post-elaborazione.
