Product Description

Custom Welded Steel Rotomolding Mold for Plastic Vertical Water Tower

Product Overview

SUNMORE ROTO Custom Welded Steel Rotomolding Mold is heavy-duty rotational molding tooling independently designed and manufactured for producing vertical plastic water storage towers. This robust mold features thick carbon steel plate integral welding with multiple reinforcing ribs to enhance structural rigidity. The finely polished mold cavity ensures excellent demolding performance.

Key Features & Benefits

Reinforced Construction: Thick steel plate with circumferential and vertical reinforcing ribs provides high structural rigidity and resistance to deformation during long-term rotary heating
Uniform Heat Conduction: Steel material ensures even heat distribution during rotomolding, reducing product wall thickness variations
Custom Sizing: Available in various specifications based on required volume, diameter, and height requirements
Optimized Demolding: Polished mold cavity with scientific draft angles enables smooth finished tank removal
Cost-Effective Production: More economical than aluminum molds, ideal for large batch continuous production
Comprehensive Service: Complete mold design, fabrication, finishing, trial rotomolding, and technical support

Our company supports the national cross-basin water transfer project of Brazil with large plastic storage tanks. Custom ultra-large rotational molds greatly improve production efficiency compared with old split iron molds. Wall thickness of finished tanks is uniform, the reject rate is cut down obviously, which helps us smoothly finish government order delivery.

We adopt this 3T industrial rotomolding mold to produce large tanks for factory continuous water supply system. The aluminum mold has outstanding thermal uniformity, finished tanks own consistent wall thickness without sink mark. It can run uninterrupted round-the-clock production, greatly improving our daily output of industrial water storage containers.

We purchased this 20-ton aluminum rotomold for oversized chemical storage tanks used in municipal critical infrastructure projects. After field commissioning, the optimized integral aluminum structure ensures uniform heat distribution across the huge mold body. The finished ultra-large tanks have consistent wall thickness without sagging or deformation. It perfectly meets the strict tank standard of US municipal infrastructure, and we plan to order another two sets for new government projects.
