SFM100C Dual-Plate Paper Folding Machine
This gallery documents the early development of the SFM100C, from initial design concepts to physical prototypes.
The photographs show the progression from the original black thermoformed housing to the finished appearance, incorporating painted light-gray panels and custom branding.
Gallery 2: SFM100C with Horizontal Conveyor Stacker
This gallery shows the SFM100C equipped with its horizontal conveyor stacker, including photographs taken during development and at a trade show.
The conveyor was designed as an interchangeable module, allowing the machine to be configured with either horizontal delivery or the vertical stacker shown in Gallery 3.
Gallery 3: SFM100C with Vertical Stacker
This gallery shows the SFM100C equipped with its vertical stacker, an alternative to the horizontal conveyor configuration.
The photographs highlight the interchangeable design and how the vertical stacker collects finished self-mailers while reducing the space required for product delivery.
The SFM100C is a two-plate paper folding machine designed and built for high-volume self-mailer production. Developed from initial 3D CAD concepts through fabrication, assembly, and testing, the machine progressed from an early prototype to completed production equipment.
The design incorporates multiple folding configurations, an integrated contact glue system with custom-developed components, and interchangeable horizontal conveyor and vertical stacking options. Selected configurations were also adapted to specific customer requirements.
The CAD renderings, prototype photographs, and operational videos below document the machine's development, mechanical construction, and capabilities, including standard folding, duplex operation, perforation, and finished-product stacking.

English & Spanish Brochures
Below are front and back views of the SFM100C marketing brochures, available in both English and Spanish, highlighting its key features and specifications.
Video Demonstrations
These videos demonstrate the SFM100C operating in standard C-fold and duplex folding configurations, including perforation and vertical stacking.
The demonstrations show the machine's mechanical operation, folding sequences, batch processing, and handling of finished self-mailers.
SFM100C: C-Fold Operation and Batch Mode Demonstration
SFM100C: Duplex Mode with Vertical Stacker Module
SFM100C: Duplex Mode Operation with Perforation Module
SFM100C: C-Fold Output with Vertical Stacker Module
This two-part video begins with a walkaround of the SFM100C, highlighting its layout and build quality before transitioning into a standard C-fold demonstration with continuous feed. The second segment shifts focus to batch mode operation, showing the control interface used to configure batches of 10 mailers every 3 seconds. Both segments showcase the machine's performance and adaptability in real mailing production scenarios.
This video showcases the SFM100C configured in duplex mode, utilizing a center actuator with dual glue nozzles to apply adhesive for double-sided mailers. As folded pieces exit the machine, a perf module slits and perforates them into two separate self-mailers. The demonstration includes a close-up of the finished product and a detailed look at the perf module in action, illustrating how the machine efficiently handles duplex processing with precision and clean separation.
This video demonstrates the SFM100C configured with the vertical stacker module during C-Fold operation. The footage focuses on the stacking process, showing how folded self-mailers are neatly organized within the vertical tray. At the end of the run, the completed stack is removed for closer inspection, providing a clear view of the fold quality. The video concludes with a walkaround of the vertical stacker module, highlighting its compact design and functionality outside the machine for added clarity.
This demonstration features the SFM100C operating in duplex mode with the vertical stacker. The system folds a single sheet, then slits and perforates it down the center as it exits the machine—producing two individual self-mailers from each sheet. The vertical stacker collects both pieces, and the video concludes with a close-up of the stacked samples being removed and torn along the perforation, showcasing the precision of the dual output process.
Vertical Delivery Module - VD100
The VD100 is a vertical delivery module designed for the SFM100C folding machine. It collects finished self-mailers in an upright stack, providing a compact alternative to the horizontal conveyor.
The interchangeable design allows the folding machine to accommodate different production layouts and material-handling requirements.
Glue Gun Solenoid
The glue gun solenoid was developed specifically for the SFM100C's contact-glue system. Unlike conventional solenoid valves, the design keeps adhesive separate from the actuator.
A gravity-fed glue line supplies adhesive to the nozzle, where a spring-loaded ball controls its application. When actuated, the ball briefly contacts the moving paper to apply glue, then retracts to seal the nozzle.
The assembly incorporates machined stainless-steel components, Delrin caps, and nickel-plated surfaces, with fabrication and plating performed in-house.
