Plastic Sign Letters

Plastic sign letters offer exceptional versatility, affordability, and design flexibility for dimensional signage applications. Our plastic letter collection includes injection-molded letters, thermoformed plastic letters, and custom-cut acrylic options suitable for interior and exterior installations across all business types.

Injection Molded Plastic Letters

Injection molded plastic letters are manufactured by injecting heated plastic resin into precision molds, producing letters with consistent quality and detailed features. This manufacturing process enables complex letter profiles with returns, multiple depth options, and integrated mounting features.

Molded letters are available in hundreds of standard colors, with custom color matching available for corporate identity requirements. The plastic materials used resist UV degradation, maintaining color vibrancy through years of outdoor exposure. High-impact plastics ensure durability in high-traffic areas where occasional contact may occur.

Popular applications include retail storefront signage, interior office identification, restaurant menus, and directional wayfinding systems. The lightweight nature of molded plastic simplifies installation while reducing structural mounting requirements.

Thermoformed Plastic Letters

Thermoformed letters, also known as vacuum-formed letters, are created by heating plastic sheets and forming them over molds. This process produces dimensional letters with smooth curved surfaces and substantial visual depth at economical price points.

The thermoforming process accommodates larger letter sizes than injection molding, making it ideal for major building identification where dramatic scale creates impact. Thermoformed letters work particularly well for illuminated signage, as their hollow construction allows internal LED or neon lighting.

Custom Cut Acrylic Letters

Custom-cut acrylic letters are precision-fabricated from acrylic sheets using laser cutting or CNC routing technology. Acrylic's optical clarity, brilliant colors, and modern aesthetics make it a premier choice for contemporary signage design.

Clear acrylic creates stunning effects when backlit, appearing to glow from within. Colored acrylic provides vibrant, saturated hues that resist fading. Mirror acrylic and specialty finishes add unique visual interest. The ability to cut any font or shape provides unlimited design flexibility.

Acrylic letters mount flat against walls or on standoffs to create floating effects with shadow lines. Multiple layers of colored acrylic can be stacked to create dimensional depth and color combinations.

Painted and Metal-Faced Plastic Letters

For applications requiring the visual impression of metal letters at reduced cost, painted plastic letters and metal-faced options provide effective alternatives. Metallic paints simulate brass, bronze, copper, and aluminum appearances on lightweight plastic substrates.

Metal-faced letters laminate thin metal sheets to foam or plastic cores, combining authentic metal surfaces with lightweight, affordable construction. These options suit budget-conscious projects requiring professional metallic aesthetics.

Durability and Performance

Modern plastic formulations deliver exceptional outdoor performance. UV stabilizers prevent yellowing and color fade. Impact-resistant materials withstand accidental contact and minor impacts. Plastic letters generally require minimal maintenance, with periodic cleaning using mild soap and water maintaining their appearance for years.
