Product Description
Custom Rotomolded Special-Shaped Plastic Water Tank is an integrated one-piece rotomolded tank manufactured using thickened industrial-grade LLDPE raw material. Formed by one-step rotational molding without any welding seams, these irregular PE water storage tanks are designed specifically for machinery equipment water storage in limited installation spaces.
Product Overview
Our custom rotomolded special-shaped plastic water tanks feature seamless construction using thickened industrial-grade LLDPE raw material. The one-step rotational molding process eliminates welding seams, ensuring leak-proof performance. Available in custom irregular shapes to fit various limited equipment installation spaces with multiple volume specifications. These special-shaped PE tanks offer compact structure, outstanding corrosion resistance, and stable liquid storage performance for cooling water storage, equipment circulating water, waste liquid storage, and clean water storage in engineering machinery, agricultural vehicles, environmental protection equipment, and industrial machinery.
Key Features & Benefits
  • Integral Seamless Rotomolded Tank Body: One-time rotomolding forming without splicing or welding seams eliminates leakage risks for long-term stable storage of cooling water, circulating water, and weak corrosive industrial liquids.
  • Thickened Industrial-Grade LLDPE Raw Material: Anti-aging construction with uniform wall thickness resists acid, alkali, rust, and ultraviolet rays. Black tank shell blocks sunlight to prevent algae growth with service life over 10 years.
  • Custom Special Irregular Outline: Supports fully customized asymmetric outlines, multi-layer variable-height structures, and exclusive mounting solutions to perfectly match compact layouts of construction machinery and industrial equipment.
  • Multi-Preserved Ports Design: Customizable water inlet, outlet, overflow port, and drain port with adjustable hole positions, calibers, and thread standards for flexible pipeline connections.
  • Built-In Multi-Layer Reinforcing Ribs: Integrated internal and external reinforcing ribs provide high rigidity and anti-deformation performance when fully filled with liquid.

Frequently Asked Questions
Can the shape and size of this special-shaped water tank be fully customized?
Yes, we support full OEM customization per customer mechanical equipment drawings, including irregular tank outline, overall dimensions, wall thickness, hole layout, and reinforcing rib structure to adapt to various narrow installation spaces of industrial equipment.
Why choose seamless rotomolded special-shaped PE tank instead of welded plastic tank?
One-piece rotomolded tanks have no welding seams to eliminate liquid leakage risks. Thick industrial LLDPE is anti-aging and corrosion resistant, and customized irregular shapes can make full use of narrow inner spaces that standard tanks cannot fit.
Can the black tank body stop algae breeding inside?
The tank includes anti-UV black masterbatch that completely blocks sunlight penetration through the tank wall, effectively inhibiting algae and moss reproduction to keep internal liquid clean for long-term storage.
