PU Mold for Bar Fridge
Tailor-made molds for bar fridges, enabling compact refrigeration units to achieve 'small size, strong insulation'—perfectly fitting limited spaces like bars and apartments
Why Bar Fridges Need Specialized PU Molds
The core requirement for bar fridges is achieving efficient cooling (4-10℃ for beverage storage) within limited spaces (typically 60-80cm in width), while meeting diverse scenario needs (e.g., built-in bar counters, retro designs, lockable mini-cabinets). This demands insulation to achieve “zero-waste filling” in narrow cavities (maximizing internal storage space) and maintain uniform density in irregular structures (e.g., curved doors, corner cabinets) to avoid localized cold loss.
UREXCEED‘s specialized PU molds for bar fridges are engineered to resolve the “small space, high demand” conflict. Unlike generic small molds (prone to foam accumulation or voids in corners), our molds feature miniaturized runner designs and optimized irregular cavities, ensuring uniform distribution of polyurethane foam in compact structures. This guarantees 100% space utilization while achieving insulation performance comparable to large refrigerators. Whether you’re producing retro mini bar fridges, built-in bar counter refrigerators, or commercial beverage display units, our molds help your products strike the perfect balance between “space adaptation” and “cooling efficiency.”

How UREXCEED PU Mold Elevates Bar Fridge 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 bar fridge.
Precision Filling of Compact Cavities to Maximize Storage Space
Space in bar fridges is precious, and traditional molds often cause uneven foam distribution leading to: ① Uneven inner walls (wasting 5-8% storage space); ② Local over-thickness (increasing cabinet depth). Our molds address these with two key designs
Four micro-gates (3mm diameter) are placed in 60cm-wide cavities, with PLC-controlled injection volume (±1g error) ensuring uniform foam filling from all sides to center. Inner wall flatness reaches 0.5mm (vs. 1.5mm for traditional molds).
Mold cavity design supports ultra-thin 20-25mm insulation layers (traditional molds require 30mm), increasing internal storage space by 12% for the same external dimensions (e.g., a 60cm-wide fridge can hold 3 more standard wine bottles).
Rounded transitions (R=5mm) replace right-angle cavities, combined with side micro-vent holes (0.1mm) to eliminate 99% of corner air bubbles (traditional molds have >8% corner bubble rate).
Special runners designed for curved doors (radius 100-150cm) create foam density gradients from edges (45kg/m³) to center (35kg/m³), ensuring glass edge sealing while reducing door weight by 15%.
Molds feature 0.3mm-precision edging grooves, enabling direct bonding between PU foam and wood-grain PVC panels or metal trim (adhesion strength >1.5N/cm), eliminating post-assembly processes (production efficiency +25%).
Removable inserts enable one-step molding of lock installation grooves, cup holder recesses, and LED strip channels (positional accuracy ±0.2mm), avoiding secondary processing that damages insulation.
Adaptation to Retro and Irregular Structures for Scenario-Specific Designs
Bar fridges often rely on unique aesthetics to attract consumers (e.g., curved retro doors, wood-grain edging, brand-customized panels). Our molds support one-step molding of complex shapes:
Adaptation to Small-Batch, Multi-Variety Production to Reduce Customization Costs
The bar fridge market primarily involves small-batch customization (e.g., 50-100 units for chain bars), with high traditional mold change costs (15% of unit cost). Our molds reduce costs through flexible design:
Magnetic front panels allow replacement of brand logos or surface textures by changing only 3kg panel inserts (changeover time <30 minutes) without adjusting the entire structure.
Lock, light strip, and thermostat requirements are designed as independent modules (<5kg), enabling rapid combination based on orders (e.g., switching from "lockable model" to "transparent door model" in just 1 hour).
For customers with annual output <5000 units, "alloy steel + partial hardening" combinations reduce costs by 20% while ensuring 50,000-cycle lifespan (meeting small-batch needs).
0.5mm-wide drainage grooves at door-cabinet interfaces, combined with high-density foam (48kg/m³) create "thermal bridge barriers," reducing condensation by 60% (meeting commercial kitchen hygiene standards).
Optimized foam distribution reduces overall weight by 8% while increasing insulation R-value by 10% (meeting EU ERP Class A efficiency), saving 85kWh/year per unit.
Mold surface treatments meet FDA 21 CFR 177.1350 food contact standards, ensuring no safety risks from accidental foam-beverage contact (verified via SGS migration testing).
Dual Compliance with Energy Efficiency and Safety Standards for Commercial Use
Bar fridges must meet commercial safety standards (e.g., anti-leakage, anti-condensation) and energy requirements. Our molds ensure compliance from the source:
