Just align the folding position and start! Improve invoice shipping operations and reduce postage costs!

A certain gas company manually folds printed invoices, inserts them into envelopes, and ships them to customers. They process about 1,000 letters each month, and before shipping, multiple people divide the work, making it a very labor-intensive task. To address this, they introduced our mail sealer, the "Pressure-Sealed Postcard Creation Machine PS-300 Series." After implementation, this product has a processing capacity of 4,300 letters per hour, allowing the previously multi-person task to be completed by one person in about 15 minutes, significantly improving work efficiency. [Case Study] ■ Challenges - Monthly invoice shipping tasks and the burden of postage costs ■ Benefits of Implementation - Successful significant improvement in work efficiency and postage costs *For more details, please refer to the PDF document or feel free to contact us.
