Dry Powder Deposition

Solvent-less electrostatic powder development technologies as utilized in the digital reprographic industry are perfectly suited to controllably deposit, coat, meter, dispense dry powder onto small and large surfaces, both flat and three dimensional. Many billions of dollars of R&D investments have been made over the last 50 years, specifically directed at dry powder development for the electrophotographic and electrostatic imaging applications.

The powder materials can be almost anything, conductive or non-conductive material, magnetic or non-magnetic material, from 5 to 100 microns in size. However, it is imperative that the properties of the dry powder material be matched to the right dry powder electrostatic deposition technology, and there are hundreds of variants of such. The good news is that TPR is uniquely positioned as the definitive independent expert in all electrostatic dry powder development technologies as used in the digital printing industry. 

All electrostatic development technologies are potentially suitable for integration into your unique powder deposition application. The specific selection of alternatives will depend upon the details of your application requirements. The available technologies include:

  • Single Component Development (SCD) and Dual Component Development (DCD)
  • Contact and Non-contact Development
  • Inductive and Tribo-active Charging
  • Magnetic and Non-magnetic powders
  • Conductive and Non-conductive powders and substrates

Torrey Pines Research understands how critical it is to match the properties of the powder to the substrate to the electrostatic deposition system hardware. With TPR's extensive experience in the digital reprographics industry, TPR is able to select from a smorgasbord of hardware implementation examples suitable for quickly prototyping your specific application.

Typical application requirements for dry powder deposition applications include the following:

  • Dry powder materials
    • From ~ 5 to 100 microns in size
  • Solvent-less process
  • High area coverage
    • Large volumes of material
  • Precise metering/thickness control Uniform coating
  • Static (decorative) or variable information coating 
  • Contact or non-contact process
  • Primarily for manufacturing
