Frequently Asked Questions

What customization services does this steel water tank rotomold support?

We support full OEM customization according to water tank design drawings, including total volume, cylinder height, top opening size, bottom radian and external contour to produce plastic water tanks of different usage scenarios.

Will the steel mold deform after long-term high-temperature operation?

The mold is made of thick carbon steel plate with full penetration welding and surrounding reinforcing frames, high structural rigidity, effectively resisting thermal expansion deformation during long-time cyclic heating.

How to ensure no flash on the edge of the molded water tank?

The split flange adopts multi-point uniform locking structure, the upper and lower mold surfaces are closely attached without gaps, so the melted PE raw material will not overflow to form thick flash.

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 multiple sets of 4T utility-grade aluminum rotomolds for regional municipal scattered water supply projects. The mold has balanced thermal conductivity, finished plastic water tanks feature even wall thickness and comply with US domestic drinking water inspection standards. Small footprint brings convenient workshop layout, we will arrange repeated orders for new district water supply renovation projects.

Our factory mainly supplies farm fuel storage tanks for pastoral and crop planting areas across Argentina. This custom rotational mold is optimized for LLDPE raw material. Compared with old iron molds, product rejection rate drops significantly, finished fuel tanks can resist outdoor sunshine and temperature change well.
