Our design patents for seat assembly equipment and seat testing equipment include patents for seat torsion spring assembly, seat clamping equipment, an actuating force measuring device, a seat height pumping spindle, an access device for inspection & assembly of electric units, a lightweight jig for seat model changes, and a peripheral device for bolts used for seat assembly.


In addition to being a main supplier of seat assembly and inspection equipment to Hyundai, our complete seat assembly lines are also installed at DAS, Hyundai M Seat, Hyundai Dymos, Adient, Johnson Controls, Lear, and Faurecia.

Seat Mechanism Assembly Equipment | Lines

Lines can be supplied as fully automated or semi-automated with a capacity to produce several seat part models. Automated seat assembly equipment consists of complete automatic assembly, transport, handling, testing, and production processes, including a  traceability solution. The semi-automatic lines allow cost reductions and can improve throughput of automobile seat parts.

Seat mass production lines are built based on the required takt time which guarantees the precise sequencing of production and testing processes.

For modern seat assembly plants, we offer advanced assembly automation solutions to synchronize the line with specific car build schedules and automate seat transferring from the seat conveyor to the main assembly line.


Seat Cushion Assembly Line | Project Experience

We have supplied fully automated lines consisting of the following processes and stations: free flow conveyor, jigs pallets, balance and cushion spring assembly, grease injection, testing stations including electrical components testing, cushion slide, height, fool proof testing stations. We have also delivered recliner operating force testing stations, soundproof testing stations, PLC, POP systems, and checking fixtures.

Automated cushion frame seat assembly lines for power seats are equipped with part handling solutions with robots transferring components directly to and from processing centers. Using RFID tracking, PLCs track pallet movements and seat serial numbers associated with pallets at the initial station.

The line has multiple HMIs for maintenance purposes and downtime reduction with an option to stop sections of the line for repairs and specific production requests.


An automatic preventive maintenance alert system has been implemented to block equipment until a specific task is complete.

Seat Assembly Lightweight Jig

LPR Global provides pallet jigs for automotive seat assembly lines with a layer of aluminum foam to reduce the weight of the jig and allow quicker jig and seat assembly replacement. The jig’s main application is to allow smoother seat model changes on a pallet. With the standard weight of jigs used in the automotive industry reaching up to 85kg, our lightweight 45kg jig reduces line noise, extends the lifetime of the conveyor, shortens cycle times, and shortens tool change over time.
