Tend the press, and run the work behind it.
Tending presses, pulling hot parts, and running the deflash-trim-inspect-pack work between molding machines and the shipping dock.
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.
Hot, dull jobs lose people
Machine tending next to a hot press is repetitive, uncomfortable work that floors struggle to staff and keep. A cell takes the dull, hot, between-cycle tending so scarce labor moves to setup, quality, and higher-value work.
Thin margins, short runs
Plastics margins are thin and runs are short and varied, so dedicated tooling rarely pays back before the next changeover. A software-reconfigurable cell amortizes across the whole SKU mix instead of one part.
Reshoring high-mix work
Reshored molding and finishing brings high-mix, contact-rich work back without the labor to staff it. A cell that tends machines and runs secondary ops makes that work viable on domestic floors at competitive cost.
The contact-rich jobs on a plastics line.
One cell, reconfigured per part — not a new machine for every job on the floor.
Part removal
Pull molded parts from the press or take-out and stage them clear of the platen.
Degating
Separate parts from runners and clip sprues and gates without stressing the part.
Deflashing
Trim and deburr flash from parting lines and edges with force-aware contact.
Insert loading
Place metal inserts or threads into the mold before the shot for insert molding.
Trimming
Trim thermoformed or extruded parts to profile and clear scrap webbing.
Assembly
Snap, press, or fasten molded components into finished subassemblies.
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.
