The production process of rotational molding water tanks typically includes the following steps:
Material Preparation: Select suitable polyethylene (PE) or polypropylene (PP) materials and cut, clean, and dry them as required.
Mold Making: Create a mold according to the water tank's design requirements. The mold is usually made of steel or aluminum and can withstand high pressure and temperature.
Heating and Preheating: Heat the mold to an appropriate temperature to ensure the material melts and flows evenly.
Injection Molding: Inject the preheated material into the mold, using pressure and temperature controllers to ensure the material fully melts and fills the entire mold cavity. After the material cools and solidifies, the shape of the water tank is formed.
Cutting and Trimming: Remove the molded water tank from the mold and cut and trim it to remove excess edges and burrs, ensuring the tank's dimensions and appearance meet requirements.
Inspection and Testing: Inspect and test the finished water tank to ensure its quality meets standards. For example, check for leaks and measure the tank's dimensions and capacity.
Packaging and Transportation: The water tanks will be inspected and properly labeled and protected to ensure safe transportation to the customer's designated location.
