SUNMORE Custom Rotomolding Aluminum Mold for HDPE Insulated Cooler Box & Thermal Storage Container
Product Overview
This OEM/ODM rotomoulding aluminum mold is a high-precision rotational mould independently designed and manufactured by SUNMORE factory. Specifically engineered for one-piece rotomolding of HDPE insulated boxes, cold chain coolers, outdoor ice chests, and food-grade thermal storage containers. Constructed from high-quality cast aluminum alloy, this mold features excellent thermal conductivity, uniform heat distribution, and high dimensional accuracy. Ideal for mass production of various sized insulated boxes to meet diverse needs in food delivery, cold chain logistics, catering services, outdoor camping, fishing, and temperature-sensitive product storage.
Problems We Solved
  • Poor thermal conductivity leading to uneven wall thickness: Our high-grade aluminum alloy mold ensures uniform heat transfer, producing consistent wall thickness for enhanced thermal insulation and structural strength
  • Complex sealing structure leading to surface defects: Precision CNC machining delivers smooth, seamless insulated boxes with perfectly aligned sealing edges for improved thermal performance and leak-proof capability
  • Undercut and functional design causing difficult demoulding: Optimized split-type structure with precision positioning and quick-release clamps enables fast assembly, disassembly, and damage-free demoulding
  • Low wear resistance leading to short service life: Professional anti-corrosion and anti-wear treatment maintains high precision and smooth surfaces for tens of thousands of production cycles
Specifications
Material High-Quality Cast Aluminum Alloy
Processing Technology CNC Machining + Multi-step Polishing + Surface Anti-corrosion & Anti-wear Treatment
Customization Supports OEM/ODM customization of box size, shape, sealing structure, latch positions, handle mounting points, divider features and other functional accessories
Structure Split mould with reinforced frame, quick-lock clamps and standard rotomoulding equipment interface
Applications
Used for rotomolding production of HDPE insulated boxes, cold chain coolers, outdoor ice chests, catering thermal containers, and medical temperature-controlled storage boxes. Widely applicable to food delivery, cold chain logistics, catering services, outdoor camping, fishing, picnics, tailgating parties, and temperature-sensitive product storage.
Selection Guide
Choose this mold when:
  • You need mass production of high-quality HDPE insulated boxes and thermal storage containers for cold chain and outdoor use
  • You require high-precision molds to reproduce complex sealing and functional features, ensuring consistent wall thickness and excellent thermal performance
  • Your products are for food-grade or cold chain applications and demand high leak-proof, heat/cold retention and durability standards
Choose other options when:
  • Small-batch trial production or simple-shaped insulated box designs (standard mold solutions available for cost optimization)
  • Special-purpose insulated boxes (medical-grade, ultra-low temperature) or custom-sized containers (custom mold solutions available upon request)
Frequently Asked Questions
Q: Can you customize insulated box molds with different sizes and functional designs?
A: Yes, we provide full OEM/ODM customization services, supporting various sizes (such as 20L, 50L, 80L, 120L), shapes and functional features (latches, handles, dividers, sealing grooves) according to your requirements.
Q: What are the advantages of aluminum mold for insulated box production?
A: Aluminum mold has excellent thermal conductivity, which speeds up heating and cooling cycles, improving production efficiency. It also ensures uniform heat distribution, resulting in consistent wall thickness, smooth surface finish and high detail reproduction, which is critical for the sealing, thermal performance and durability of insulated boxes.
Q: Can the mold produce insulated boxes with custom latches, handles or sealing structures?
A: Yes, we can design the mold according to your requirements, including custom latch positions, handle mounting points, sealing grooves, internal dividers and other functional accessories.
Q: What is the service life of this aluminum mold?
A: With proper maintenance, the mold can support tens of thousands of rotomoulding cycles, maintaining stable precision and producing high-quality insulated boxes for a long time.
