Frequently Asked Questions

Can the vertical tank cavity diameter, height and annular rib layout of this steel water tower mold be customized?

Yes, full OEM drawing customization is supported. We design and process the steel mold strictly according to your finished vertical plastic water tank drawings, adjusting cavity dimensions, rib layout, and all reserved pipeline hole positions as required.

What is the advantage of integral circular base frame compared with square support frame?

Circular base bears rotary force evenly during rotomolding operation without local stress concentration, providing better anti-deformation performance suitable for long-term continuous high-frequency mass production of large vertical water tanks.

Is this large vertical water tower mold compatible with mainstream rotomolding equipment?

Standard connecting flanges and integral lifting lugs are reserved on circular steel frame, compatible with swing arm, shuttle and carousel rotomolding machines of most domestic and foreign brands without extra reconstruction.

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.

We purchased this 20-ton aluminum rotomold for oversized chemical storage tanks used in municipal critical infrastructure projects. After field commissioning, the optimized integral aluminum structure ensures uniform heat distribution across the huge mold body. The finished ultra-large tanks have consistent wall thickness without sagging or deformation. It perfectly meets the strict tank standard of US municipal infrastructure, and we plan to order another two sets for new government projects.

We order custom-size aluminum roto molds for diversified plastic containers including water tanks and industrial bins. The manufacturer can adjust mold dimension flexibly per our drawings, and the aluminum alloy with thickened structure delivers outstanding durability after months of uninterrupted cyclic high-temperature production. Mold deformation is not observed, so we keep placing repeat orders for new product development.
