This high-precision rotational mold is independently designed and manufactured by SUNMORE factory for one-piece rotomolding of HDPE cold chain coolers, food-grade thermal storage containers, catering insulated boxes, and temperature-sensitive product storage vessels. Made from high-quality cast aluminum alloy, it ensures excellent thermal conductivity, uniform heat distribution, and high dimensional accuracy for mass production.
Key Problems Solved
Uniform Wall Thickness
Eliminates uneven heating issues that cause inconsistent wall thickness, ensuring optimal thermal insulation and structural strength for long-distance transportation.
Precision Surface Finish
Prevents surface defects on intricate areas like lid edges and sealing grooves, producing smooth, seamless boxes with perfect alignment for superior thermal performance.
Efficient Demoulding
Optimized split-type structure with precision positioning and quick-release clamps enables fast, damage-free demoulding even with complex undercut designs.
Extended Service Life
Professional anti-corrosion and anti-wear treatment maintains high precision and smooth surfaces through tens of thousands of production cycles.
Supports OEM/ODM customization of box size, shape according to customer drawings or samples
Structure
Split mould with reinforced frame, quick-lock clamps and standard rotomoulding equipment interface
Applications
Ideal for rotomolding production of HDPE cold chain coolers, food-grade thermal storage containers, catering insulated boxes, pharmaceutical temperature-controlled boxes, and outdoor ice chests. Widely used in cold chain logistics, food delivery, pharmaceutical distribution, catering services, outdoor activities, and temperature-sensitive product storage.
Selection Guide
Choose this mold when:
Mass production of high-quality HDPE cold chain coolers and food-grade thermal storage containers is required
High-precision molds are needed to reproduce complex sealing and functional features
Products demand high leak-proof, heat/cold retention, and durability standards for food-grade or cold chain applications
Consider other options when:
Small-batch trial production or simple-shaped cooler box designs are needed
Special-purpose insulated boxes (medical-grade, ultra-low temperature) or custom-sized containers are required
Frequently Asked Questions
Can you customize cold chain cooler box molds with different sizes and functional designs?
Yes, we provide full OEM/ODM customization services, supporting various sizes (20L, 50L, 80L, 120L), shapes, and functional features including latches, handles, stacking ribs, dividers, and sealing grooves according to your requirements.
What are the advantages of aluminum mold for cold chain cooler box production?
Aluminum molds offer excellent thermal conductivity, speeding up heating and cooling cycles while improving production efficiency. They ensure uniform heat distribution for consistent wall thickness, smooth surface finish, and high detail reproduction—critical for sealing, thermal performance, and durability of insulated boxes.
What is the service life of this aluminum mold?
With proper maintenance, the mold can support tens of thousands of rotomoulding cycles while maintaining stable precision and producing high-quality cold chain cooler boxes for extended periods.
