Frequently Asked Questions

The FD 432 closes and seals envelopes in one continuous pass rather than requiring a separate closing step before sealing, which matters significantly at the rated 18,000 envelopes per hour throughput this machine is built for. A basic office sealer or manual moistening process works fine for occasional mailings, but at high volume, combining both steps into one pass is what makes a meaningful difference in total mailroom processing time. For offices also handling incoming mail at similar volume, Formax letter openers handle that other side of the workflow.

Yes, the FD 432 is specifically built to handle both standard and nested envelopes, which matters for mailrooms that need to seal envelopes containing inserts or documents already placed inside rather than empty envelopes alone. This flexibility means the same machine covers both simple mailing runs and more complex nested mailing jobs without needing separate equipment for each format.

A precision moistening roller applies a consistent, controlled amount of moisture to the envelope flap, which produces a more reliable seal than inconsistent hand-moistening or a basic roller that applies uneven coverage. This consistency matters most at high volume, where even a small percentage of poorly sealed envelopes across thousands of pieces adds up to a meaningful number of mailing failures.

This model is genuinely built around high-volume throughput, so a smaller office sending occasional mailings would likely find the investment excessive relative to actual need. For lower-volume sealing, a basic manual sealer or moisture sponge remains more cost-effective. This equipment makes the most sense for mailrooms, print shops, or offices consistently processing large batches of outgoing mail, and browsing the brand's broader mailroom lineup under Formax shows other volume tiers if this specific model is more machine than you need.

For offices running a full mailing operation, pairing an envelope sealer with complementary equipment like an inserter for placing documents into envelopes before sealing creates a more complete mailroom workflow rather than handling each step manually. For offices already using a separate folding or stuffing process, Formax inserters handle steps ahead of sealing.
