Description
Layout & Drive System
Elliptical racetrack structure: An oval layout with 20–50 foaming stations enables continuous production of seat shells and backrests.
Chain-driven trolley system: Chain conveyors, driven by servo or variable-frequency motors, move trolleys along ground rails with adjustable takt speeds for synchronized processing.
Mold temperature control: Stations are equipped with mold temperature controllers or hot-steam heating to ensure consistent curing and material properties throughout the line.
Operational Procedures
The line automates key stages while supporting essential manual tasks:
Chain cycle drives trolleys to each station.
Air evacuation prepares fixtures for molding.
Fixture tilting, unlocking, and automatic opening ready molds for loading.
Manual actions: unloading molded parts, cleaning, applying release agents, loading raw portions.
Automatic phases: injection of PU foam, mold closing, air connections, fixture positioning, and locking.
Curing occurs before the cycle resets and the trolley advances.
This structured sequence delivers efficient, repeatable seat shell production.
Key Features & Advantages
Multi‑station racetrack layout: The oval chain structure supports up to 50 stations, enabling high production volumes with smooth part flow.
Servo/frequency-controlled chain drive: Offers precise speed control, synchronized indexing, and adjustable takt times to match production targets.
Advanced thermal management: Mold temperature controllers and hot-steam heating ensure consistent part quality and material integrity.
Semi-automated workflow: Combines automated injection, locking, and curing with manual loading and finishing—balancing efficiency with flexibility.
Quick mold change: Slip-ring power, centralized air, and quick-connect temperature/mold interfaces enable rapid changeovers and maintenance.
Applications
Production of automotive seat cushions and backrests with PU foam.
Medium to high-volume foaming lines requiring precise curing and throughput.
Retrofit installations in seating manufacturing facilities or new production lines.
