SUNMORE ROTO OEM Drawing Custom Cast Steel Rain Barrel Rotomolding Mould, Hollow Plastic Rainwater Collection Tank Rotational Mold With Integral Lifting Frame & Surrounding Quick Clamps
SUNMORE ROTO OEM Drawing Custom Cast Steel Rain Barrel Rotomolding Mould is a heavy cast steel rotational mold independently processed by SUNMORE ROTO factory. This specialized rotomold is designed for mass production of hollow plastic rain harvesting barrels, garden rainwater collection tanks, agricultural rain storage containers, and environmental water recycling plastic barrels.
Product Overview
Fully customizable based on customer product design drawings, this rain barrel rotomold features a thickened high-density cast steel mold cavity with stable and uniform heat conduction. During rotomolding heating cycles, heat spreads evenly inside the cavity, ensuring consistent wall thickness of finished plastic rain barrels while eliminating common molding defects such as surface bubbles, cold lines, sink marks, and uneven wall thickness.
The integrated heavy carbon steel lifting frame with standard lifting lugs is welded with the mold cavity, facilitating overhead crane hoisting and installation on all shuttle rotomolding machines. Multiple stainless steel quick release clamps are evenly arranged around the mold parting surface for fast locking before heating production and rapid opening after cooling demoulding.
All inner and outer surfaces feature high-temperature resistant anti-rust spraying coating, capable of withstanding long-term repeated high-temperature circulation inside heating ovens without oxidation or deformation, while simplifying residual plastic cleaning after batch production.
Key Features & Benefits
Full Drawing OEM Customization: Flexible adjustment of rain barrel structure parameters including capacity, outer contour, manhole specification, water pipe interface layout, mold wall thickness, and lifting frame size
Thick Cast Steel Mold Cavity: Balanced heat conduction for flawless rain barrel surface with smooth inner and outer surfaces free from pits, flow marks, or wall thickness deviation
Integral Carbon Steel Lifting Frame: Standard lifting lugs for efficient hoisting and machine matching, reducing mold loading and unloading time
Surrounding Multi-Point Quick Clamps: Stainless steel quick clamps evenly distributed along mold parting line to shorten mold locking and opening cycles
High-Temperature Resistant Coating: Special anti-rust paint withstands long-term cyclic high-temperature environments and facilitates easy cleaning
Universal Equipment Compatibility: Compatible with all mainstream bi-axial shuttle rotomolding machines without extra mechanical modification

Frequently Asked Questions
Can this rain barrel mold be fully customized according to my rain barrel product technical drawings?
Yes, we provide complete drawing OEM customization service. We adjust barrel capacity, outer contour, manhole size, pipe port layout, mold wall thickness and frame dimensions strictly following customer drawings to satisfy different rainwater storage barrel 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.
Is the integral lifting frame compatible with all shuttle rotomolding machines?
The lifting frame is equipped with standard positioning flanges and lifting lugs, compatible with all mainstream bi-axial shuttle rotomolding machines, PLC adjustable cycle automatic rotomolding equipment and multi-arm rotomolding machines, no extra equipment modification required during installation.
