Our company supports the national cross-basin water transfer project of Brazil with large plastic storage tanks. Custom ultra-large rotational molds greatly improve production efficiency compared with old split iron molds. Wall thickness of finished tanks is uniform, the reject rate is cut down obviously, which helps us smoothly finish government order delivery.

We ordered the 10T rotomolding mold for large water tanks supporting municipal engineering water supply projects. The aluminum mold has uniform thermal conductivity, finished large water tanks have even wall thickness with no concave or bulging. After three months of continuous mass production, mold stability is outstanding, and we are preparing to purchase three more sets for new urban water supply projects.
