Product Overview
This high-precision injection mold is purpose-built for manufacturing PC+UV protection plastic spot lamp lenses, a critical component for outdoor, automotive, and industrial lighting systems. Featuring a practical 1*2 cavity layout, the mold uses a pin-point gate runner system and mirror-polished core/cavity to deliver flawless optical quality.
Constructed for long-term stability, the mold is optimized for UV-stabilized polycarbonate resin, ensuring the finished lenses maintain high light transmittance, impact resistance, and dimensional accuracy even under harsh environmental conditions. The polished surfaces eliminate flow marks, sink marks, and haze, guaranteeing consistent light focus and clarity. Ideal for small to medium production runs, this mold provides reliable, high-quality results for spot lamp lens manufacturing.

Core Advantages
1. Mirror Polished Core & Cavity: Optical-Grade Quality
The core and cavity undergo ultra-precision mirror polishing to eliminate even the smallest surface defects:
Zero Haze, Maximum Clarity: No flow marks, sink marks, or scratches to disrupt light transmission, ensuring consistent optical performance across all lenses.
Smooth Molding & Easy Demolding: Polished surfaces reduce friction during demolding, preventing damage to delicate lens geometries and preserving the critical optical finish.
Long-Term Consistency: High-quality polishing maintains surface integrity through millions of cycles, avoiding gradual degradation that would affect lens clarity.
2. Pin Point Gate System: Preserving Optical Integrity
The precision pin-point gate runner system is tailored for optical lens production:
Minimal Optical Impact: The tiny gate mark is positioned on a non-optical surface, avoiding interference with light transmission or focus.
Automatic Clean Separation: Eliminates the need for manual trimming, reducing the risk of scratching or damaging the polished lens surface.
Balanced Melt Flow: Ensures uniform filling across both cavities, minimizing warpage, uneven cooling, and internal stress that could cause optical distortion.
3. Optimized for PC+UV Stabilized Resin
The mold is engineered to handle the unique properties of UV-stabilized polycarbonate:
Shrinkage & Warpage Control: Compensates for PC’s shrinkage characteristics, ensuring the lens maintains its precise focal geometry and dimensional accuracy.
UV Additive Compatibility: Mold temperature and cooling systems are tuned to prevent thermal degradation of UV additives, preserving the lens’s weather resistance and clarity.
Impact & Clarity Retention: Optimized venting eliminates trapped air and burn marks, delivering clear, blemish-free lenses with excellent impact resistance.
4. 1*2 Cavity Design: Flexibility & Efficiency
The dual-cavity layout offers the perfect balance for spot lamp lens production:
Cost-Effective Production: Doubles output compared to single-cavity molds without the high upfront cost of multi-cavity designs.
Consistent Optical Quality: Both cavities are precision-machined to identical specifications, ensuring every lens meets the same light transmission and focus standards.
Flexible Production: Supports both prototype testing and full-scale production, making it easy to validate lens designs before committing to mass manufacturing.
Applications

FAQ
Q1: Why is mirror polishing critical for spot lamp lens molds?
A1: Mirror polishing eliminates surface defects like scratches, flow marks, and haze, which would otherwise disrupt light transmission, reduce clarity, and cause uneven light distribution in the finished lens.
Q2: What are the benefits of a pin-point gate for optical lenses?
A2: Pin-point gates leave minimal marks on the lens surface, preserving its optical integrity. They also enable automatic gate shearing, reducing the risk of scratching or damaging the polished lens during post-processing.
Q3: How does the mold handle UV-stabilized PC resin?
A3: The mold’s temperature control and venting systems are optimized to prevent thermal degradation of UV additives, ensuring the lenses retain their weather resistance and clarity over time.
Q4: Can the mold be modified for different lens shapes or focal lengths?
A4: Yes, we offer full customization, including adjustments to cavity geometry, polishing specifications, and gate placement to match your specific lens design requirements.
