Acrylic Convex Mirror Wide Angle Safety Mirror for Traffic and Warehouse

Primary method for mass production of small convex mirrors used in supermarkets, transportation, and motorcycle applications:

• Sheet Cutting: Raw acrylic sheets cut into standard circular or square flat sheets
• Heating and Softening: Uniform heating in oven or infrared heating zone until material softens
• Vacuum Forming: Softened sheets placed over convex mold with internal vacuum creating negative pressure
• Shaping and Cooling: Atmospheric pressure forces sheet to conform to mold curvature, followed by rapid air cooling

Preferred for large-size thick convex mirrors requiring superior quality:

• Heated acrylic sheet placed between upper and lower molds
• Upper mold presses sheet to conform to convex curvature of lower mold
• Pressure maintained during cooling phase
• Results in uniform curvature and higher mirror surface flatness

Industrial standard for durable, high-performance mirrors:

• Convex acrylic sheet thoroughly cleaned to remove dust and grease
• Placed in vacuum coating chamber evacuated to high vacuum
• Aluminum wire heated to vaporize into aluminum vapor
• Aluminum molecules evenly adhere to acrylic back surface
• Forms thin, highly reflective aluminum film

Cost-effective alternative for budget applications:

• Multiple layers of silver mirror-finish reflective paint applied to convex back surface
• Mirror effect achieved through pigment reflection
• Lower cost but reduced wear resistance and weather resistance compared to vacuum aluminum coating
