FES offers consulting services in Media Handling, Structural and Contact Analysis, and Thermal Printing.  We also offer expertise in Product Design Reviews and Product Troubleshooting.

Paper Handling

We have developed a library of sophisticated software tools to help engineers design and optimize paper and film handling systems. These simulations have been applied to many products and processes, including photocopiers, fax machines, image setters, and paper and film manufacturing equipment.

We offer consulting on the following subjects related to Media Handling:

 

Single Sheet Mechanics

Modeling of single sheets moving through a paper path.

Prediction of jam, stall and roll-over conditions.

Winding Mechanics

The mechanics of wound roll production.

Prediction of core pressures, inter-layer pressures and inter-layer tensions.

Prediction of winding defects and optimization of winding tension profiles.

Nip Mechanics

Modeling of the contact region between rollers.

Prediction of sheet transport speed.

Prediction of pressures, deflections and nip width

Structural and Contact Analysis

We utilize sophisticated software tools to help engineers predict and optimize structural and contact behavior in the linear and non-linear domain.

 

We offer the following areas of consulting in Structural and Contact Analysis:

 

General Stress Analysis

Computation of stresses and deflections in loaded parts.

Contact and Friction Behavior

Analysis of contact loads and areas.

Effects of friction.

Contact and friction behavior between moving parts.

Thermal Analysis

Fully coupled transient or steady state thermal analysis.

Stress Dependent Thermal Properties or Temperature Dependent Mechanical Properties

Thermal Printing

The mechanics of thermal printing is a key ingredient in the robust design of thermal printers. We use state of the art computer simulations to predict and optimize key printing parameters such as nip pressure, head load, platen design and material property selection. In addition, we specialize in providing design solutions to the industry wide problem of ribbon wrinkling.

We offer the following areas of consulting in Thermal Printing:

 

Wrinkle Removal

Removal of ribbon wrinkling through optimum tension control, shaft alignment, and minimization of thermal loading.

Nip Mechanics

Modeling of the contact region between the print head, donor, receiver and platen.

Prediction of pressure and nip width.

Optimization of platen materials for a wide range of receiver stocks.

Temperature and Diffusion Modeling

Modeling of temperature profiles in the print head, donor and receiver layers.

Ribbon Behavior and Characterization

Characterization of ribbon behavior when subjected to tension and heat.
