PU Mold for Display Fridge
Molds built exclusively for display fridges—balancing fog-free glass clarity with strict insulation performance, creating visually appealing refrigerated displays for retail spaces.
Why Display Fridges Need Specialized PU Molds
Display fridges are the “silent salespeople” of retail, and their core challenge lies in showcasing food perfectly through large glass doors (e.g., cakes, beverages, dairy) while maintaining stable internal temperatures (2-10℃) to preserve freshness. This requires insulation to achieve “gap-free filling” around glass edges (to prevent fogging that obscures visibility) and uniform density in the cabinet frame (to avoid cold air leakage).
UREXCEED’s specialized PU molds for display fridges are engineered to solve the compatibility issues between glass and insulation. Unlike generic molds (which often cause uneven foam filling around glass edges), our molds feature precision cavity designs and optimized glass-fitting structures, ensuring seamless bonding between polyurethane foam, glass, and metal frames. This balances display clarity with the strict insulation demands of commercial refrigeration. Whether you’re producing curved bakery cases, supermarket island fridges, or upright beverage display units, our molds help your products strike the perfect balance between “display appeal” and “freshness preservation.”

How UREXCEED PU Mold Elevates Display Fridges Production
We will explain in detail the advantages of UREXCEED PU mold and let customers understand how UREXCEED PU mold can help customers produce high-quality display cabinet.
Gap-Free Glass Edge Filling to Eliminate Fogging & Cold Loss
The biggest pain points of display fridges are glass door fogging (which harms visibility) and cold air leakage at edges (which increases energy consumption). Our molds address these with three key designs:
Molds feature glass fitting grooves with ±0.5mm precision, equipped with 0.1mm-wide micro-vent holes. These ensure complete foam filling between glass and metal frames, eliminating air gaps (traditional molds have a gap rate of >5% here).
Within a 3cm radius around the glass, mold runner design increases foam density by 10% (to 45-50kg/m³), creating a “high-density insulation ring” that blocks thermal bridging (temperature fluctuation at glass edges is controlled within ±0.3℃).
Food-grade silicone pads (50 Shore A hardness) are used at mold-glass contact points, preventing glass scratches during foaming (defect rate reduced from 3% to 0.2%).
5-axis CNC machining is used for curved door molds (adjustable radius: 50-150cm), ensuring perfect alignment between foam curvature and glass (error <0.2mm) to avoid glass breakage during assembly.
Removable steel inserts are designed for display fridge features like LED light grooves, shelf supports, and thermostat recesses. This enables one-step molding of “insulation layers + functional structures,” eliminating post-production cutting (production efficiency increased by 30%).
Brand logo textures (0.3mm depth) are engraved on mold inner walls, creating subtle embossed logos on foam surfaces (no additional stickers or printing required), enhancing product recognition.
Precision Molding for Irregular Cavities, Adapting to Diverse Display Designs
Display fridges rely on unique shapes to attract customers (e.g., curved doors, sloped display platforms, branded logo grooves). Our molds support one-step molding of complex structures:
Commercial-Grade Durability for High-Frequency Production
Display fridges are commercial equipment with high customization needs, requiring molds to adapt to small-batch, multi-variety production (e.g., custom sizes for different supermarkets). Our molds are reinforced for long-term use:
S55C alloy steel (tensile strength: 650MPa) is used, with cavity surfaces treated via nitriding (hardness: HV 800). This supports over 100,000 opening-closing cycles (traditional molds: 60,000 cycles).
For display fridges of the same series but different widths (e.g., 60cm/90cm/120cm), replaceable side mold modules are designed, reducing mold change time to <1 hour (traditional molds: 4-6 hours).
Spiral cleaning rods are built into mold gates to automatically remove residual foam after each production cycle, reducing manual cleaning time (saves 8 hours of maintenance per week).
Mold surface treatments meet FDA 21 CFR 177.2600 and EU 10/2011 food contact standards, with no heavy metal migration (verified via SGS testing).
CFD flow simulation is used to optimize foam distribution, increasing the overall insulation R-value of display fridges by 15% to meet EU ERP Energy Class A standards (saves 120 kWh/year per unit vs. traditional designs).
Mold runners are compatible with bio-based polyurethane raw materials (e.g., 30% plant-based polyol), with no harmful gas emissions during foaming, meeting LEED green building certification requirements.
Food-Safety Compliance & Dual Energy Efficiency Certification
Display fridges come into direct contact with food, and commercial settings demand energy efficiency. Our molds ensure compliance from the design stage:
