Chemical & Heat Resistant Optical Molds for the Optical Industry | Unbeatable Performance

Core Specifications at a Glance

Core Advantages: Unbeatable Performance in Harsh Environments

1. Extreme Heat Resistance: Stable Under High-Temperature Molding

• 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). This stability prevents mold distortion, ensuring consistent replication of optical features (e.g., lens curvatures, prism angles) even during long production runs.
• Thermal Cycling Stability: Designed to endure rapid temperature shifts (-40°C to 300°C), making them ideal for automotive optics (headlight lenses exposed to engine heat) and industrial photonics (laser components subjected to thermal stress).
• Cooling Efficiency: Precision-machined cooling channels (optimized via CFD simulation) maintain uniform temperatures across the mold surface, reducing cycle times by 15–20% without compromising optical precision.

2. Superior Chemical Resistance: Withstands Aggressive Substances

• Broad Chemical Compatibility: Withstand acids (pH 2–12), solvents (, ethanol, isopropyl alcohol), and industrial cleaning agents—critical for medical optics (sterilized with EtO or hydrogen peroxide) and industrial components (exposed to coolants or adhesives).
• Corrosion Protection: Chrome-plated S136 steel or nickel-alloy electroformed surfaces resist pitting and degradation, meeting ISO 9227 salt spray standards (≥5,000 hours) and ensuring mold integrity in humid or chemically active environments.
• Easy Maintenance: Non-porous, chemical-resistant surfaces simplify cleaning, reducing downtime and preserving optical precision (no micro-scratches from abrasive cleaners).

3. Uncompromising Optical Precision: Clarity & Consistency

• Micron-Level Accuracy: Achieve ±0.001–0.003mm dimensional tolerance and Ra ≤0.003μm surface roughness, ensuring optical components (lenses, light guides) have blemish-free surfaces that transmit light without scatter or distortion.
• Feature Replication: Replicate micro-optical details (5μm anti-reflective textures, 10μm light-diffusing patterns) with 99.95% fidelity, critical for applications like endoscope lenses (clear imaging) or LiDAR components (precise beam shaping).
• Low Birefringence: Mold design minimizes resin stress during cooling, keeping birefringence ≤10nm/cm—essential for polarized optics (e.g., camera filters) or laser applications where light polarization must be preserved.

4. Durability for Unbeatable Longevity

• Wear Resistance: Heat-treated H13 steel (50–55 HRC) or nickel-alloy electroforms withstand abrasive fillers in glass-reinforced optical resins, supporting ≥1,500,000 cycles for high-volume production (e.g., smartphone camera lenses).
• Impact Resistance: Robust construction resists mechanical stress from high injection pressures (up to 2500 bar), preventing chipping or warping in critical areas like lens edges or prism facets.

Application Scenarios by Optical Industry Segment

Customization & Technical Expertise

• Material Matching: Select mold materials (H13, S136, nickel alloy) based on your resin (e.g., H13 for PEEK’s high temperatures, S136 for medical-grade PC).
• Design Collaboration: Our engineers optimize mold geometry for your optical design, ensuring heat/chemical resistance doesn’t compromise precision (e.g., reinforcing thin walls in light guides).
• Validation Testing: Pre-production trials under extreme conditions (thermal cycling, chemical exposure) verify performance, ensuring molds meet your longevity and precision targets.

Quality & Service Commitment

• Rigorous Inspection: Each mold undergoes 3D optical scanning (0.001μm resolution), thermal cycling tests, and chemical exposure trials to validate performance.
• Certifications: Compliant with ISO 9001, with full traceability for materials and test data.
• Lifecycle Support: Dedicated engineers provide maintenance guidelines to maximize lifespan, including cleaning protocols and wear monitoring for harsh environments.
