Product Description

Product Overview

The SUNMORE Factory Heavy Duty M Tank Rotomould is a heavy-duty vertical rotational mold independently developed and produced for mass production of large-capacity M-type HDPE plastic tanks, water storage tanks, and chemical dosing tanks. The mold features thick steel plate integrated welding forming, reinforced support frame structure, and high-precision inner cavity polishing treatment, ensuring uniform wall thickness, stable molding cycles, and long service life. Full OEM & ODM customization services are available for rotomolding manufacturers, plastic tank processing factories, and environmental equipment enterprises.

Key Features & Benefits

Thick Steel Plate Integrated Welding Structure: Super load-bearing and anti-deformation capabilities with multi-group inclined support frames to disperse heating and rotating stress during production.
High Precision Polished Inner Cavity: Mirror-finished inner wall ensures smooth tank surfaces without burrs, pits, or welding lines, reducing secondary trimming procedures.
Customizable Reserved Interface Mold Positions: Prefabricated mold inserts for agitator ports, liquid level ports, feeding openings, and bottom drain outlets according to customer requirements.
High Temperature Resistant & Wear Resistant Mold Surface: Anti-rust and high-temperature resistant coating withstands long-term oven baking and HDPE raw material friction abrasion.

Frequently Asked Questions

Will this heavy-duty welded M tank mold deform after long-term high-temperature rotomolding?

The mold body uses thickened steel plate full welding plus multi-angle inclined support frame to disperse rotating and heating stress, effectively avoiding permanent deformation under long-cycle high-temperature production.

Does the finished plastic tank need secondary trimming after rotomolding with this mold?

The inner cavity is finely mirror polished, the tank surface comes out smooth without burrs; if equipped with prefabricated reserved port inserts, all functional holes are formed in one step without post drilling modification.

What customization support can we get for rotomolding factory bulk mold orders?

We can adjust mold cavity capacity, change tank height and diameter, add built-in reserved port mold cores, optimize the overall support frame structure.

We got this agricultural seeding hopper mold via OEM customization. The steel mold is solid with fine inner finish. Produced plastic hoppers have even wall thickness and no deformation, ideal for farm seeding equipment production. The factory finished mold modification per our drawing quickly.

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 this space-saving aluminum alloy rotomold for square and rectangular plastic tanks used in factory compact workshop water storage. Optimized mold structure reduces extra idle space inside the furnace, improving single batch production quantity greatly. The finished regular tanks stack neatly to maximize warehouse space utilization, we’ve placed repeated orders for multiple specifications.
