Mactec Packaging Equipment
Small Parts, Seals and O-Ring Pouch Packaging Machines
Small rubber seals, O-rings, discs and similar parts can be packed one to a pouch on a Mactec horizontal pouch machine, as single pouches or as strips of perforated pouches, with a bowl feeder placing each part. The machines are designed and built in Sayreville, New Jersey, and each line is configured around your part and your pack.
This page is for makers of small industrial and laboratory parts who want single-use packs instead of loose parts in a bag or a blister. If your product is a patch, a device or a test kit, the pouch packaging machines page and the patch packaging guide cover those uses.
What the pouch looks like
The standard pack is a flat four-side-seal pouch: two webs of film sealed on all four edges with the part inside, the style of the paper packs that mints and lozenges come in. People who find us by searching for a horizontal wrapper or a flow wrapper usually have this pack in mind. You choose how the pouches come off the machine:
- Single pouches, cut apart and collected in a box or tray.
- Strips of perforated pouches, left joined so the user tears one off at a time. The machine perforates between pouches and cuts the strip to the length you want, and the strip can be rewound onto a roll for a dispenser box. Boxing strips by hand is often the simpler choice.
- A tube or fin pack, with a seal down the back like a candy bar wrapper, is reviewed as a custom project rather than offered as a standard format.
Which machine
The MTHP150 horizontal form-fill-seal machine is the usual fit, and the in-stock MTHP300XL is the larger option. Both are built for flat or placed products: the machine forms the pouch, takes the part by pick-and-place or another automatic loader, then seals, perforates and cuts. Strips of perforated pouches and single pouches run on the same machine. Multi-lane configurations run several pouches across the film at once, which is how a compact machine reaches a useful output on a one-part pack. A vertical machine such as the MTVP100 can also make the pouch; whether the part can be fed reliably into a vertical pouch is the question engineering answers first.
Feeding is the hard part
A coated or slippery part will not place itself. Parts can be fed by hand, semi-automatically or fully automatically, and the cost of the line rises in that order. Fully automatic feeding, usually a vibratory bowl feeder with a track that presents one part at a time, is what turns a pouch machine into a packing line for parts. Mactec works with a feeder vendor, or with the feeder maker you already use for assembly, and the feeder is specified around your part sizes. Several part sizes on one machine means a feeder and tooling plan for each, so list every size up front.
What to send us
- Part drawings or photos with dimensions, and how many sizes you run.
- The pouch size you have in mind, and whether you want single pouches or perforated strips.
- The film: paper-type or plastic, plain or printed, and whether you have a specification or a sample that already seals.
- How many parts you need to pack per shift.
- Where the machine will sit: floor space, power and compressed air.
How Mactec builds the line
Every parts line is a custom build on a standard platform. Engineering reviews the part, the film and the feeding method, runs a sample where practical, then writes a proposal that names the pouch format, the feeder, the tooling and the acceptance test. Factory acceptance testing takes place in Sayreville, New Jersey, and you can witness it. Operator training and spare parts come from the same plant. See custom packaging machines for how a project moves from sample to shipment.
