Thermoforming Process
Our end-to-end thermoforming workflow ensures dimensional accuracy, optical clarity, and repeatable quality across every production run.
Material Selection
Optical-grade PMMA, PC, or ABS sheet sourcing and inspection
Precision Heating
Uniform temperature distribution to softening point without degradation
Mold Forming
High-precision tooling shapes complex spherical and aspherical profiles
Cooling & Trimming
Controlled cooling, CNC trimming, and edge finishing for clean geometry
QC & Coating
Optical inspection, hardening, AR/AG and functional coating application
Optical-Grade Substrates
We work with a carefully curated selection of high-performance thermoplastic materials, each chosen for superior optical clarity, chemical resistance, and thermoforming processability.
PMMA (Acrylic)
Exceptional optical clarity, UV stability, and lightweight properties ideal for visors and display covers.
Polycarbonate (PC)
High impact resistance and optical clarity. Preferred for safety visors, helmets, and industrial guards.
Hard-Coated PC
Pre-hardened PC sheets with surface reinforcement for enhanced scratch resistance without post-processing.
Multi-Layer Composites
Co-extruded and laminated sheets combining optical and structural properties for specialized applications.
Equipment & Capabilities
State-of-the-art thermoforming machinery operated in cleanroom environments ensures consistent, high-quality output at scale.
Multi-Station Thermoforming Lines
High-speed rotary and shuttle forming machines with precise zone heating control for complex optical geometries.
CNC Trimming & Edge Finishing
5-axis CNC routing for post-form trimming with ±0.1mm tolerances and polished optical-quality edge finishes.
Class 1,000 / 10,000 Cleanrooms
Fully enclosed cleanroom production areas meeting ISO Class 6/7 standards for dust-free optical surface quality.
Automated Coating Integration
Inline hardening, AR/AG deposition, and anti-fog treatment lines integrated directly with forming operations.
Post-Forming Treatments
Every thermoformed component can be enhanced with VIIST's proprietary functional coatings and surface treatments.
Hardening (HC)
Thermally or UV-cured hard coats achieving 3H-5H pencil hardness for superior scratch resistance on formed surfaces.
AR / Anti-Reflective
Multi-layer AR coatings that minimize surface reflections to below 0.5%, maximizing light transmission and visual clarity.
AG / Anti-Glare
Controlled surface texturing that diffuses incoming light to reduce harsh glare in bright environments and outdoor use.
Anti-Fog
Hydrophilic surface treatments that prevent condensation buildup, critical for medical, sports, and industrial safety eyewear.
Anti-Static
Permanent or semi-permanent anti-static treatments that prevent dust attraction for cleaner, maintenance-free optical surfaces.
Color & Gradient Printing
Custom color gradients, tints, photochromic treatments, and 3D laser engraving for aesthetic and functional differentiation.
Thermoforming Applications
Our thermoformed optical components serve diverse demanding industries where clarity, durability, and precision are non-negotiable.
Helmet Visors & Face Shields
Curved, high-impact PC/PMMA visors for motorcycle, military, and industrial helmets with optional anti-fog and AR coatings.
Ski & Sports Goggle Lenses
Thermoformed double-lens systems with photochromic, anti-fog, and UV400 treatments for extreme sports performance.
Medical Protective Goggles
Sterile-compatible, anti-fog thermoformed shields meeting medical device standards for clinical and laboratory environments.
