SUNMORE ROTO OEM Custom Vertical Cast Steel Water Tank Rotomolding Mould is a heavy-duty vertical cast steel rotational mold designed and manufactured by SUNMORE ROTO factory. This specialized water tank rotomold is engineered for mass production of hollow vertical plastic storage containers, including rainwater collection tanks, domestic water storage barrels, sewage septic tanks, industrial chemical liquid storage vessels, and agricultural fertilizer mixing tanks.
The mold cavity features thickened high-density cast steel with uniform and stable thermal conductivity. During the heating cycle of rotomolding equipment, heat distributes evenly inside the cavity, ensuring consistent wall thickness of finished plastic tanks and eliminating common molding defects such as air bubbles, cold flow lines, sink marks, and uneven wall thickness.
A circular radial spoke carbon steel lifting frame is integrally welded around the mold opening edge. This multi-radial spoke structure evenly disperses the weight of the large vertical mold to maintain stable support during heating and static placement, while standard lifting lugs are reserved on the outer ring for overhead crane hoisting. Heavy-duty toggle quick clamps are evenly arranged along the full circular parting surface to enable rapid locking before production and fast opening after cooling demoulding.
All inner and outer surfaces of the cast steel mold are sprayed with high-temperature resistant anti-rust coating, which withstands long-term repeated high-temperature circulation inside heating ovens, resists oxidation and deformation, and allows easy cleaning of residual plastic raw materials after batch production.
We provide full drawing OEM customization service. Customers can adjust tank total volume, barrel height, top and bottom caliber, manhole size, inlet/outlet pipe port layout, mold wall thickness, and radial spoke lifting frame dimension according to water tank design drawings. This vertical mold has wide compatibility with all mainstream bi-axial shuttle rotational molding equipment and supports customized internal reinforcing rib structure and external embossed logo for finished plastic tanks.
Key Features & Benefits
Full Drawing OEM Customization: All structural details customizable following customer technical drawings, including tank capacity, vertical height, top & bottom diameter, manhole specification, pipeline interface layout, mold wall thickness and circular radial spoke lifting frame size
Thickened Cast Steel Mold Cavity: Balanced heat conduction for flawless tank surface with smooth inner and outer surfaces free from pits, flow marks, or wall thickness deviation
Circular Radial Spoke Integral Lifting Frame: Uniform load bearing and convenient hoisting with multi-spoke circular carbon steel frame that distributes weight evenly and supports fast overhead crane loading/unloading
Full Perimeter Toggle Quick Clamps: Evenly distributed heavy-duty clamps shorten mold locking and opening cycles, boosting daily production output
High-Temperature Resistant Anti-Rust Coating: Extends mold service life by enduring long cyclic high-temperature environments and facilitating easy cleaning
Universal Equipment Compatibility: Compatible with all mainstream bi-axial shuttle rotomolding machines, PLC cycle adjustable automatic equipment, and multi-arm shuttle rotomolding machines

Frequently Asked Questions
Can this vertical water tank mold be fully customized according to my storage tank technical drawings?
Yes, we provide complete drawing OEM customization service. We adjust tank capacity, vertical height, top-bottom caliber, manhole size, pipeline port layout, mold wall thickness and radial spoke lifting frame dimensions strictly following customer drawings to satisfy different plastic storage tank production demands for environmental, civil and agricultural projects.
Will the thick cast steel cavity deform after long-time repeated high-temperature operation inside the oven?
The mold adopts thick high-density cast steel blank, after precision CNC machining and overall high-temperature resistant anti-rust spraying treatment, no deformation or rust oxidation occurs after long-term repeated high-temperature heating cycles.
What are the advantages of circular radial spoke lifting frame and full perimeter toggle quick clamps?
The circular multi-spoke steel frame evenly distributes the weight of the oversized vertical mold to keep stable bearing during heating, integrated lifting lugs support fast crane hoisting; full perimeter heavy toggle clamps provide uniform strong clamping force to realize fast mold opening and closing, greatly improve workshop overall production efficiency.
