Dual-Density Car Seat Foaming Line Solution
Configure dual-density seat-foam production around the selected material systems, zone geometry, molding sequence and production target.
Dual-Density Car Seat Foaming Line Solution
With more than two decades in polyurethane complete equipment, Haifeng Polyurethane Machinery delivers a turnkey PU foaming line for dual-density car seats, built around one-shot dual-density molding, precise density control, flexible mixed-line efficiency and safety. The line integrates a 3-component dual-density high-pressure foaming machine, a pouring robot and a turntable line. One machine completes the dual-density pouring of the soft-density layer and the high-resilience support layer, enabling mixed-line foaming production of front seat, rear seat and headrest. Dosing accuracy reaches ≤±0.3% with density fluctuation of ≤±3%.
One-Shot Dual-Density
A four-component dual-chamber mixing head molds the soft layer and high-resilience layer in one shot on a single line.
Mixed-Line Flexibility
Front seat, rear seat and headrest foam on one line with one-click recipe changeover.
Customized to your seat mold and dual-density process, the turnkey line is delivered with factory commissioning, pilot production support and after-sales service for stable, high-quality output.
Implementation Process
Our turnkey service covers the full journey from on-site survey and recipe design to commissioning, pilot production and long-term after-sales support.
Customized Solution Planning
Engineers survey on site and customize the solution based on seat mold structure, dual-density process, target cycle time and environmental standards.
Dual-Density Recipe Design
The R&D center completes customized dual-density recipe and mixing-index process design with feasibility verification.
Turnkey Equipment Delivery
Core equipment including the 3-component dual-density foaming machine, pouring robot and turntable line is built in our factory, and field engineers complete installation and commissioning.
