• Cast aluminium mold body offers excellent thermal conductivity, uniform heating, and a long service life.
• Heavy-duty toggle clamps enable easy opening and closing with reliable clamping force.
• Precision casting combined with CNC machining delivers a smooth cavity surface and reduces post-processing for finished products.
• Reasonable venting layout effectively prevents bubbles and deformation during the rotomolding process.
• Customizable cavity structure allows for added logos, buckle slots, and handle positions as required.
• Sturdy support frame for convenient hoisting and installation on rotomolding equipment.

This mold is used to produce 20L insulated cooler boxes and is widely applied in outdoor camping, fishing, seafood transportation, cold chain storage, picnics, and beverage insulation.

We accept OEM and ODM customization. Provide drawings, samples, or design ideas, and we can adjust the internal capacity, box shape, handle installation, drain plug, and buckle structure, as well as emboss your brand logo onto the mold cavity.

Each mold is cleaned and coated with anti-rust oil, then wrapped in stretch film and secured in a sturdy fumigation-free wooden case. We support sea freight, air freight, and land transportation, and can arrange shipment according to the customer's forwarder or our cooperative logistics partners.
