12-Step Intelligent Inspection
High-resolution AI machine vision paired with multidimensional optical sensors inspects 100% of lenses for edge burrs, center thickness, diameter tolerance, and printing concentricity.
Manufacturing Excellence
Global Color Contact Lens Hub Built for Scale & Safety
Hunan Haipuming Technology Co., Ltd. (Liangguo Group) functions as a pivotal high-precision color contact lens production facility within the global manufacturing footprint of Eyebeauty Technology Co., Ltd. Representing a substantial capital investment in automated ophthalmic engineering, this modern manufacturing campus was built to meet the strictest medical device specifications demanded by brand owners, optometry groups, and pharmaceutical regulators worldwide.
The facility integrates fully automated cast-molding machinery, laminar airflow cleanrooms, high-purity water filtration loops, and computer-controlled thermal curing tunnels. With continuous investments in manufacturing hygiene and digital process validation, the plant maintains full raw-material-to-carton traceability across daily disposable, monthly disposable, and extended-wear cosmetic lenses.

Engineering & Standards
Core Manufacturing Innovations
From monomer distillation to sub-micron surface inspection, every stage guarantees ocular comfort, physiological safety, and reproducible batch consistency.
Bio-Safe Color Encapsulation
Medical-grade cosmetic colorants are strictly embedded between transparent polymer layers. Pigment cannot contact the cornea or conjunctiva, ensuring zero pigment migration.
Monomer Distillation & Extraction
Pioneering multi-stage lens extraction cycles wash away unreacted monomer residues, keeping eye irritation to near-zero levels and optimizing hydration retention throughout daily wear.
96% Visible Light Transmittance
Through state-of-the-art optical matrix purification, optical zone light transmittance achieves 96%, exceeding the national medical standard of 89% for sharper visual acuity.
Cleanroom Cast-Molding Lines
Equipped with ultra-precise diamond tooling mold bases, providing micrometer-accurate sag height, smooth edge profile design, and tear-film circulation optimization.
Agile Turnaround & Flexibility
Flexible production scheduling allows rapid order ramp-up: standard in-catalog product runs dispatch in 3 to 10 days, while custom OEM formulations complete within 30 to 45 days.
Controlled Process
Strict Medical Device Manufacturing Flow
Every single lens follows an unbroken chain of custody and rigorous quality checkpoints under ISO 13485 standards.
01
Polymer Synthesis
Hydrogel and silicone hydrogel matrix ingredients undergo high-vacuum blending, degassing, and molecular filtration to ensure uniform optical refractive index.
02
Sandwich Tinting
Bio-inert pigments are precision-printed onto the front optical matrix layer and sealed by the posterior carrier polymer, eliminating direct tissue interaction.
03
Precision Cast & Cure
Precision matched mold cavities are filled via robotic micro-dispensers, then polymerized through ultraviolet and thermal energy cycles for exact geometry.
04
Hydration & Autoclave
Lenses undergo continuous ultrasonic hydration, automated cosmetic inspection, blister cavity ultrasonic sealing, and verified 121°C moist-heat terminal sterilization.
Assurance & Governance
Built for Seamless Global Registration
For international optical brands, distributors, and private label partners, regulatory compliance is the cornerstone of brand security. As the primary manufacturing base for Eyebeauty Technology Co., Ltd., Hunan Haipuming Technology maintains rigorous audit readiness year-round.
We provide comprehensive technical documentation packs including biocompatibility test files (cytotoxicity, systemic toxicity, ocular irritation), stability aging data, packaging integrity validation, and batch sterilization records to support partner submissions across the Americas, Europe, Middle East, and East Asian jurisdictions.
