Signature Plastics History



Our History

The history of Signature Plastics began in 1973 with a company named Comptec. Comptec  quickly became a leading manufacturer of two-shot molded plastic parts for customers worldwide, serving the computer, telecommunication, electronic, automotive, medical, and consumer products markets. The company eventually grew to become the world’s largest independent supplier of keycaps for the computer industry.

Signature Plastics, LLC was formed in 2001 following the purchase of a portion of the assets, customer base and technologies of the US division of Comptec Incorporated. Today, Signature Plastics is an industry leader in two-shot molding custom keycaps for a variety of user-interface electronic input devices. Manufacturing capabilities include both manual and automated part transfer methods. Manufacturing flexibility allows for economical prototype and short run capability as well as high volume manufacturing utilizing multi-axis robotic part handling. The company inventories a wide variety of standard and engineered polymers with hundreds of color options.

The company also specializes in epoxy based pad printing and dry transfer sublimation printing. These secondary decorating processes are used to add single or multi-color graphics to products. To enhance graphic durability of pad printed parts, a UV cured hard coat is often applied.

Signature Plastics also manufactures proprietary custom keycaps for back-lighted applications. In this process, keys are first molded in a translucent material and then painted with a thin coat of highly durable automotive paint. Graphics are then cut through the paint, using a CNC engraver, exposing the translucent substrate material. There is an increasing demand for back-lighted keycaps on electronic input devices used in low-light production editing venues, such as theatre performances, television and motion picture productions.

The company’s capabilities extend to sonic welding, thermal insertion, mechanical assembly, product collating and custom packaging.

Signature Plastics utilizes a broad network of manufacturing partners to assist in providing additional value-added services including:

  • product/part design and development
  • tool and fixture design and fabrication
  • rapid prototyping
  • custom color matching
  • specialty materials requiring unique filtration and/or transmission characteristics
  • laser marking
