Why Polyurethane for Car Seats
Comfort & Support
PU foam is molded to the exact ergonomic shape of each seat, giving consistent softness, rebound and long-term ride comfort.
Durability
High-resilience polyurethane resists fatigue and deformation, keeping seats supportive over years of daily use.
Design Flexibility
Formulations and molds are tailored per model — from economy seats to premium, MPV and racing designs.

How PU Car Seats Are Foamed
The mold is preheated and a release agent applied. A high-pressure foaming machine meters and mixes the polyol and isocyanate, injecting the blend into the mold. The mold closes, the foam expands and cures to the seat shape, then the finished cushion is demolded for trimming and upholstery.
Frequently Asked Questions
Which production line should I choose for car seats?
Carousel lines suit high-volume single models; rotary lines suit medium-to-high volume with multiple stations; banana lines suit start-ups with limited space. Tell us your target output and we will recommend the right layout.
High-pressure or low-pressure foaming for car seats?
Car seats are normally produced with high-pressure machines for stable mixing, uniform density and better surface quality on complex cushion and backrest shapes.
Can you customize molds to our seat models?
Yes. We design and manufacture aluminum or steel molds to your exact cushion, backrest and headrest geometry, including automatic temperature control and demolding features.
What after-sales support do you provide?
Every line ships with English manuals, remote debugging, optional on-site installation, operator training and a 5-year warranty.
