Product Description

Custom Steel Frame Rotomolded Water Tank Mould

Heavy-duty thick welded steel rotational mold for industrial PE plastic water storage tank manufacturing, designed and produced by SUNMORE ROTO.

Product Overview

This heavy-duty all-steel rotational mold features an integrally processed thick carbon steel plate cavity with full seamless welding. Equipped with surrounding reinforced steel frame and quick release locking handles, it's specially developed for mass production of various PE plastic water storage tanks including industrial, agricultural, domestic underground, and fire water tanks. All dimensions, inner rib structures, manhole positions, and inlet/outlet reserved positions can be fully OEM customized according to customer requirements.

Key Features & Benefits

Thickened Carbon Steel Mold Cavity: High structural rigidity resists deformation during long-term high-temperature rotation baking, ensuring consistent wall thickness in mass production
All Welded Reinforced Steel Frame: Stable rotation operation with uniform force distribution during high-speed rotation, improving production safety and molding stability
Quick Release Steel Locking Clamps: Convenient opening and closing operation without auxiliary tools, shortening production cycles and improving efficiency
Precision CNC Machining: Smooth inner cavity surface with no burrs for easy demolding and reduced finishing work on finished tanks
Full OEM Customization: Customizable tank shapes, internal structures, dimensions, and wall thickness for various PE storage water tank applications

Frequently Asked Questions

Can the tank cavity shape, internal ribs and manhole positions be customized?

Yes, we provide full OEM customization service. We design and process the mold strictly according to your finished water tank drawings, including adjusting the outline shape, inner reinforcing rib distribution, top manhole size and reserved pipeline hole positions.

Will this thick steel mold deform after long-term high-temperature rotomolding cycles?

The mold cavity is made of thick carbon steel plate with full penetration welding, matched with surrounding heavy steel reinforcing frame. The overall rigidity is extremely high, maintaining stable shape after thousands of high-temperature rotation cycles without bulging or deformation.

Is the mold compatible with most mainstream rotomolding equipment?

We reserve standard connecting flanges and lifting lugs on the mold frame, compatible with swing arm, carousel and shuttle rotomolding machines of most domestic and foreign brands without extra transformation required.

Excellent custom fuel tank rotational mould for industrial production. Good thermal conductivity greatly shortens rotomolding cycle and reduces raw material waste. The inner surface is smoothly polished, no burr on finished tank surface. Satisfied with their ODM design service.

We purchased multiple sets of infrastructure-grade rotomolding molds for municipal engineering centralized water supply projects. The aluminum mold has even heat distribution, finished large water tanks feature uniform wall thickness without shrinkage or deformation. It can cope with continuous mass production for government bidding projects, and we intend to place additional orders for new urban infrastructure construction.

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.
