Force-controlled assembly, reconfigured in software.
Closed-loop force control for insertions, press-fits, and fastening, reconfigured in software for every part you build.
The work is changing faster than you can staff it.
The dexterous, high-mix, contact-rich jobs are exactly the work classical automation was never built to hold — and the people who used to absorb it are getting harder to find.
Skilled assembly labor is gone
Manual contact-rich assembly depends on tactile workers who are increasingly hard to hire and retain. Closed-loop force control captures that feel in software, holding assembly throughput as the experienced workforce ages out and turnover climbs.
High-mix breaks fixed tooling
Shorter runs and more variants mean rigid cells spend more time being retooled than running. A force-controlled cell that reconfigures per part in software absorbs the mix without new fixtures, recovering capacity lost to changeover.
Rework is the hidden cost
Cross-threaded fasteners, cracked housings, and unseated connectors surface late and cost far more to fix than to prevent. Force-verified assembly catches bad joints at the station, cutting scrap, rework, and warranty exposure as work reshores.
What the service covers.
One cell, reconfigured per part — not a new machine for every job on the floor.
Press-fits
Seat bearings, bushings, and pins to target force with press-distance and force verification.
Snap-fits
Engage plastic snaps and clips, confirming seating by the force signature at lock-in.
Threaded fastening
Drive screws and bolts to specified torque with cross-thread detection and reject handling.
Connector insertion
Mate electrical connectors and ribbon cables, confirming full seat by insertion force.
Gasket seating
Place and press gaskets and seals into grooves under controlled, even compression.
Peg-in-hole
Insert shafts and dowels into tight-clearance bores using force-guided alignment search.
One cell. Assembly, inspection, finishing.
Qualified off-site. Running in two weeks.
The slow, hard engineering happens on our floor — so the cell arrives tested and dialed in instead of tying up your team for months. A new part is a reconfiguration, not a rebuild.
