Custom Cast Steel Vertical Water Tower Rotomolding Mold
SUNMORE ROTO OEM Custom Cast Steel Vertical Large Water Tower Rotomolding Mould is a heavy-duty cast steel rotational mold designed for mass production of large-volume hollow plastic vertical water storage tanks, civil water towers, agricultural irrigation containers, and industrial liquid storage barrels.
Product Overview
This specialized vertical water tower rotomold features a thickened high-density cast steel cavity with stable, uniform heat conduction. During heating cycles, heat distributes evenly throughout the cavity, ensuring consistent wall thickness in finished plastic water tanks while eliminating common defects such as air bubbles, cold lines, sink marks, and uneven wall thickness.
The mold includes an integrated heavy steel support lifting frame that combines supporting stand and crane lifting lugs into one piece, solving stability issues during heating and hoisting operations. It can be directly installed on all types of shuttle rotomolding machines. Multiple stainless steel quick release clamps are evenly arranged around the mold parting surface for fast locking before production and rapid opening after cooling demoulding.
All inner and outer surfaces feature high-temperature resistant anti-rust coating, resisting long-term repeated high-temperature circulation inside heating ovens. The coating prevents oxidation and deformation while making residual plastic easy to clean after batch production.
Key Features & Benefits
Full Drawing OEM Customization: Adjust all structural parameters including tank capacity, height, manhole specification, water pipe layout, mold wall thickness, and support frame size to meet mass production demands
Thickened Cast Steel Mold Cavity: Balanced heat conduction ensures flawless tank surfaces without pits, flow marks, or wall thickness deviation, significantly reducing product reject rates
Integrated Support Lifting Frame: Dual-function design provides stable support during operation and convenient hoisting via overhead crane, reducing mold loading/unloading time
Multi-Point Quick Clamps: Stainless steel quick clamps evenly distributed along the parting line enable rapid clamping and disassembly, boosting daily production output
High-Temperature Resistant Coating: Special anti-rust paint withstands long-term cyclic high-temperature environments, preventing rust and deformation while facilitating easy cleaning
Universal Compatibility: Standard positioning flange and installation interface design compatible with all mainstream bi-axial shuttle rotomolding equipment

Frequently Asked Questions
Can this large vertical water tower mold be fully customized according to my water tank technical drawings?
Yes, we provide complete drawing OEM customization service. We adjust tank capacity, height, manhole size, pipe port layout, mold wall thickness and support frame dimensions strictly following customer drawings to satisfy different large vertical plastic water tank production demands.
Will the thick cast steel cavity deform after long-time repeated high-temperature operation inside the oven?
The mold adopts thick high-density cast steel blank, after precision CNC machining and overall high-temperature resistant anti-rust spraying treatment, no deformation or rust oxidation occurs after long-term repeated high-temperature heating cycles.
What is the advantage of the integral support lifting frame?
The frame integrates bottom supporting stand and overhead lifting lugs, the support legs keep the heavy mold stable when placed statically or heated; lifting lugs support fast crane hoisting, fit all shuttle rotomolding machines without extra brackets.
