Core Advantages
1. Extreme Heat Resistance: Stable Under High-Temperature Molding
Our molds excel in high-heat conditions, critical for processing heat-resistant optical resins:
- Temperature Tolerance: Operate continuously at 200-300°C, withstanding the high melt temperatures of advanced optical materials like PEEK (340-390°C), COC (270-300°C), and LCP (300-350°C).
- Thermal Cycling Stability: Designed to endure rapid temperature shifts (-40°C to 300°C), making them ideal for automotive optics and industrial photonics.
- Cooling Efficiency: Precision-machined cooling channels maintain uniform temperatures across the mold surface, reducing cycle times by 15-20%.
2. Superior Chemical Resistance: Withstands Aggressive Substances
Molds resist harsh chemicals, ensuring longevity in demanding cleaning and production environments:
- Broad Chemical Compatibility: Withstand acids (pH 2-12), solvents (ethanol, isopropyl alcohol), and industrial cleaning agents.
- Corrosion Protection: Chrome-plated S136 steel or nickel-alloy electroformed surfaces resist pitting and degradation.
- Easy Maintenance: Non-porous, chemical-resistant surfaces simplify cleaning, reducing downtime.
3. Uncompromising Optical Precision: Clarity & Consistency
Even in harsh conditions, these molds maintain the precision required for high-performance optics:
- Micron-Level Accuracy: Achieve ±0.001-0.003mm dimensional tolerance and Ra ≤0.003μm surface roughness.
- Feature Replication: Replicate micro-optical details (5μm anti-reflective textures, 10μm light-diffusing patterns) with 99.95% fidelity.
- Low Birefringence: Mold design minimizes resin stress during cooling, keeping birefringence ≤10nm/cm.
4. Durability for Unbeatable Longevity
Built to outlast standard optical molds, delivering sustained performance over extreme cycles:
- Wear Resistance: Heat-treated H13 steel (50-55 HRC) or nickel-alloy electroforms withstand abrasive fillers.
- Impact Resistance: Robust construction resists mechanical stress from high injection pressures (up to 2500 bar).
