Product Description

Custom Steel Frame Rotomolding Vertical Water Tank Mold

Thick Cast Aluminum Rotational Mould for Industrial Plastic Water Storage Tank Production

Product Overview

This integrated rotational mold is independently manufactured by Sunmore Roto. The mold cavity features thickened carbon steel plate with precision internal polishing, matched with a full-surround all-welded heavy custom carbon steel frame and evenly distributed heavy-duty quick release lock clamps. The inner cavity forms vertical wave-shaped industrial plastic water storage tanks in one rotomolding process, with uniform internal heating delivering smooth tank surfaces and consistent wall thickness. Specially developed for mass production of vertical industrial PE water tanks, equipment circulating water containers, sewage storage barrels, and large plastic liquid storage vessels.

Key Features & Benefits

Thickened Polished Steel Cavity: Balanced heat transfer during rotomolding reduces shrinkage marks, air bubbles, and uneven wall thickness. Lower cost and stronger impact resistance than cast aluminum molds.
Custom All-Welded Steel Frame: Multiple heavy quick lock buckles ensure tight sealing. Rapid opening and closing reduces PE raw material adhesion and shortens molding cycles.
Reinforced Anti-Deformation Welded Steel Lifting Frame: High-rigidity steel frame restrains mold expansion and deformation under high-temperature rotation, supporting stable continuous mass production.
Full-Dimensional OEM Customization: All mold parameters customizable based on customer drawings, including height, diameter, internal wave structure, port positions, and wall thickness.
Wear Resistant Steel Mold Surface: Anti-rust wear-resistant treatment resists long-term high-temperature baking and frequent abrasion, reducing maintenance frequency.

Frequently Asked Questions

What customization services does this vertical industrial water tank thick steel rotomold provide?

We support complete OEM customization according to customer vertical water tank design drawings, including mold overall height & diameter, internal wave texture outline, layout of liquid inlet & outlet ports, reinforcing rib positions and finished tank wall thickness, matching vertical storage tanks for industrial circulation water, sewage treatment and agricultural irrigation.

Why choose thick carbon steel as cavity material for vertical water tank mold?

Thick solid steel plate has stable heat conduction performance with lower cost than cast aluminum molds, good impact resistance; precision polished inner cavity makes tank surface smooth without secondary polishing. Uniform wall thickness strengthens finished tank structural strength and reduces post-processing procedures.

Is the custom steel quick lock frame reliable for long-time mass production?

Evenly distributed heavy quick lock buckles cooperate with full-surround thick welded custom steel frame to lock mold tightly. No expansion, displacement or flash gaps during high-temperature rotation, stable and reliable for long-cycle continuous batch production of vertical industrial plastic water storage tanks.

We upgraded our old iron molds to these optimized aluminum rotational molds for vertical cylindrical water tanks. After engineering optimization, the mold heating uniformity is greatly improved, cooling time is shortened by nearly a quarter. Cylindrical tank wall thickness is even, no partial thin wall during rotomolding. Product yield increased obviously, we will purchase molds for more tank volumes later.

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.

We purchased a full set of integrated aluminum rotomold for rectangular HDPE water tanks. The space-saving integrated design greatly reduces our workshop placement area compared with split molds we used before. Mold surface finish is fine, finished square tanks have uniform wall thickness with no bubbles or deformation during rotomolding. Technical team helped us complete system docking quickly, stable quality for mass production, will add new tank size molds next year.
