Frequently Asked Questions

If you have any further questions, please reach out to us and we will be glad to help.


What types of materials can the CardSerter™ insert?

CardSerter™ is designed to handle small postcard-sized inserts such as promotional flyers, discount coupons, thank-you notes, loyalty offers, and seasonal marketing campaign collateral—making it easy to enhance the customer unboxing experience.


How fast is the CardSerter™ system?

CardSerter™ delivers high-speed performance, inserting up to 3,000 cartons per hour per line. It’s built for high-volume operations and peak seasons, maintaining speed without compromising accuracy.


Can I use multiple CardSerter™ units in sequence?

Yes. Whether deploying as a single unit or a series, we can deploy multiple CardSerters™ to insert different materials (e.g., instructions + promotional piece) based on control logic or LPN rules. One common implementation is to have one unit insert a promotional material to cross-sell a specific product, while another one promotes a different product – configured by the LPN or UPC.


Does the CardSerter™ require specific software?

The CardSerter™ can run in two ways—integrated with our Warehouse Control System (WCS) to read and associate insert data from the LPN or order information, or configured for standalone operation using PLC programming and HMI controls. This flexibility lets you choose the right level of intelligence based on your needs and system complexity.


How reliable is the CardSerter™ in long-term use?

Engineered for durability, the industrial-grade friction feeder is low-maintenance and highly reliable—ensuring consistent insert placement and uptime across demanding, fast-paced environments. Routine care includes simple checks such as cleaning feed belts and rollers to remove dust or debris, wiping sensor lenses to maintain accurate detection, and inspecting wear parts during scheduled downtime to keep the system performing at its best.
