R&D Formulation Capability
Support material evaluation and formulation windows around density, hardness, rebound, compression behavior, pore structure, and application performance.
Manufacturing Capabilities
From Foam Formulation to High-Volume Converted Components
YUNDY supports customers from polyurethane foam formulation and block foaming to splitting, lamination, adhesive backing, die-cutting, CNC shaping, sampling, and high-volume production. With R&D support, scalable capacity, and broad customization capability, YUNDY helps turn foam material requirements into repeatable production programs.
Core Manufacturing Strengths
A stronger supply program depends on material know-how, scalable production, controlled conversion, and practical engineering communication.
High-Volume Foam Production
Support scalable block foam production and repeat manufacturing for volume programs, with production planning for ongoing customer supply.
Raw Material Supply Chain
Work with qualified polyurethane raw-material suppliers and approved partners where applicable, with project-specific review of material systems and supply requirements.
Custom Converted Foam Components
Support lamination, adhesive backing, die-cutting, punching, CNC shaping, cavity cutting, and application-specific converted foam components.
Sampling-to-Production Support
Support sample development, drawing review, material selection, fit check, process validation, and production ramp-up.
Batch Consistency & Packaging Delivery
Support thickness control, dimensional consistency, batch traceability, packaging requirements, and shipment preparation for B2B supply programs.
Capability chain
Five manufacturing stages from material target to delivery
The workflow is organized around the decisions customers need to make before production and the controls needed for repeatable supply.

Manufacturing Equipment Snapshot
The images below show selected representative equipment from YUNDY's Chongqing facility. YUNDY's overall manufacturing capability is supported by a broader multi-site footprint across Dongguan, Chongqing, Ningbo, and the new Huizhou base, with additional production, processing, and testing equipment across the group.
Note: The equipment photos show selected examples from the Chongqing facility. YUNDY's broader production and processing support is based on its multi-site manufacturing footprint.
Foaming & Curing
Foaming, curing, and foam body storage support stable material production, curing management, and odor improvement review for automotive and industrial programs.
Precision Cutting & Sheet Processing
Ring cutting, horizontal slicing, and long-sheet processing support sheet, roll, strip, and downstream conversion requirements.
PIP Headrest Foaming & Molding
High-pressure molding, automatic mold opening, and cleaning/blowing processes support molded foam component production and process repeatability.
Testing & Validation Equipment
YUNDY supports foam material review through testing equipment for environmental exposure, fatigue, hardness, thickness, rebound, tensile and compression behavior, odor, flammability, and material structure evaluation.
PIP Lab Testing Support
Application-specific test setups support molded foam development, pressure behavior review, dimensional checks, and deformation evaluation.
Environmental & Heat Exposure
Environmental and heat exposure equipment supports review of material behavior under controlled temperature, humidity, and heating conditions.
Fatigue, Rebound & Compression
