Why tie-bar-less machines are getting more attention in North America

Tie-bar-less machines have been around for decades, but they’ve always been a bit misunderstood in North America. That’s changing.

As automation, mold accessibility, and floor space become bigger concerns, more shops are starting to see what they offer.

Here’s what’s driving that interest:

1. Easier mold changes and setup

No tie-bars means better access. That makes mold install, EOAT setup, and manual inspection simpler and safer. Less time in the press. Less risk of damage.

2. Automation flexibility

With full access from three sides, it’s easier to bring in side-entry robots, insert feeders, or end-of-line handling without clashing with machine hardware.

3. More compact footprint

You get the same clamping force in a smaller package. For shops trying to fit more output into the same square footage, that’s a real advantage.

4. Wider mold space for tricky tools

If you’re running molds that are wide but not heavy think multi-cavity medical or family molds tie-bar-less lets you fit those tools without bumping up a tonnage class.

So why hasn’t adoption been faster? Mostly habit. Many molders default to what they know. But as layouts get tighter and automation becomes the norm, this machine design is worth a second look.

Have you worked with tie-bar-less machines?

If not, what’s been holding you back, space, application fit, or just familiarity?

If you're curious whether your parts or tools are a good match, happy to walk through it.
