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.

Our factory produces agricultural water tanks and industrial chemical containers. After comparing multiple mold suppliers, we chose this manufacturer. Their aluminum mold processing workmanship is fine, good thermal conductivity shortens our production cycle. Custom sizes from small containers to large water tanks can all be realized here.

We bought multiple sets of steel fuel tank molds for our industrial tank production line. Solid steel structure improves mould service life greatly, finished plastic fuel tanks feature even wall thickness and excellent tightness without leakage. The supplier completes OEM modification as per our drawings efficiently.
