5. Other related scenarios

According to the 2021-2025 China Insulation Box Industry Supply and Demand Forecast and Development Prospect Research Report released by Zhongyan Puhua, the global insulation box market size reached 1.905 billion US dollars (equivalent to 12.73 billion RMB) in 2020, among which the Chinese insulation box market size was 230 million US dollars (equivalent to 1.541 billion RMB). The report also predicts that the compound annual growth rate (CAGR) of the global insulation box market size will remain at 4.99% in the future.

4.If you are considering entering the insulation box Rotomolding Production industry, we will fully provide a complete set of support

solutions, including:

1. Machine model selection: We will accurately match a suitable production machine model for you based on your actual production demand and insulation box size specifications to ensure production efficiency and product adaptability.

The following is an introduction to carousel rotomolding machine and Shuttle Type Rotomolding Machine ".

2. Mold design and placement: Based on existing product drawings or customized design drawings, we will scientifically plan the loading method of molds on the machine. Throughout the process, we will optimize the design and placement scheme with the core principles of reducing demolding difficulty, improving production efficiency, and ensuring product quality.

3. Mold display and material recommendation: We will provide professional mold material suggestions for different types of insulation boxes. For example, for insulation boxes with complex structures and many deep-cavity designs, aluminum molds are recommended, which can make the finished products have high surface finish and better precision; for medium and large insulation boxes with relatively simple structures, iron molds are recommended, which have the advantages of long mold service life and fast molding heating speed.

4. Foaming process recommendation:

When manufacturing insulation box molds, fixture molds with matching structures are usually customized simultaneously to ensure that the products achieve high-quality foaming effect and thermal insulation performance. During operation, placing the insulation box that has just been removed from the rotomolding mould and still maintains a certain temperature into the fixture can effectively avoid the deformation problem caused by excessive pressure in the insulation box interlayer during the foaming process. 

5. At present, the thermal insulation material we use most in insulation box production is PU (polyurethane). Due to its outstanding characteristics of low thermal conductivity and high cost-effectiveness, this material has become the mainstream choice for insulation box insulation layers.

6. In addition, if you have relevant needs, we can also provide professional foaming equipment recommendations to help you improve the production chain.
