Product Description

Custom Horizontal Water Tank Cast Aluminum Rotomold

High-performance rotational mold for LLDPE rectangular plastic water storage tanks with anti-deformation welded steel frame construction.

Product Overview

This OEM custom horizontal water tank cast aluminum rotomold features an integrated thick cast aluminum casting process with fully penetrated seamless welded carbon steel frame and multiple heavy-duty steel quick-release latches. Designed specifically for mass production of horizontal rectangular LLDPE plastic water storage tanks, it serves applications including domestic water storage, agricultural irrigation, industrial chemical liquid storage, vehicle-mounted water tanks, and underground buried water containers.

We provide comprehensive OEM customization services based on customer drawings, adjusting cavity dimensions, wall thickness, external reinforcing rib layouts, and manhole/water inlet/outlet positions. The cast aluminum cavity ensures uniform thermal conductivity and smooth inner surfaces, resulting in consistent wall thickness and clear rib structure for reduced post-processing requirements.

Key Features & Benefits

Thick Integral Cast Aluminum Cavity: Balanced heat conduction and smooth molding surface prevent local overheating and ensure smooth demolding with minimal post-processing.
Full Welded Reinforced Steel Frame: High rigidity anti-deformation structure withstands high-speed rotary loads during continuous production, extending mold service life.
Multi-Group Steel Quick Release Latches: Rapid mold opening and closing without tools reduces cycle times and increases daily production output.
Cross Reinforcing Rib Integrated Design: Pre-molded rib grooves create pressure-resistant reinforcing ribs on finished tanks, enhancing compression and impact resistance.
Full Customization Capability: Complete customization of rectangular tank dimensions, capacity, rib layout, and pipeline positions to meet specific project requirements.

Frequently Asked Questions

Can the size, cross rib layout and pipeline hole positions of this rectangular water tank cast aluminum mold be customized?

Yes, full OEM drawing customization is supported. We design and process the cast aluminum mold strictly according to your finished rectangular water tank drawings, adjusting cavity dimensions, rib layout and all reserved hole positions as required.

What are the advantages of cast aluminum cavity compared with all steel cavity molds?

Cast aluminum material provides better thermal conductivity for uniform heating during rotomolding, resulting in smoother finished tank surfaces. The mold is lighter than all-steel molds and resists rust in long-term high-temperature production environments.

Is this horizontal rectangular water tank mold compatible with mainstream rotomolding machines?

Standard connecting flanges and integral lifting lugs are included, making it compatible with swing arm, shuttle, and carousel rotomolding equipment from most domestic and international brands without requiring extra modifications.
