This Heavy Duty Steel Rotomoulding Dustbin Mould is a professional carbon steel rotational mould independently manufactured by SUNMORE factory. It is specially designed for mass production of heavy-duty outdoor HDPE garbage bins via rotomolding process. Compared with aluminum moulds, this steel mould features stronger structural rigidity, better heat resistance and longer service life, making it ideal for continuous, high-volume production of outdoor waste bins for public and commercial use.
Cause
In actual production of heavy-duty garbage bins, traditional moulds often face these problems:
1.Poor structural strength leads to mould deformation after repeated high-temperature heating cycles
2.Uneven welding and processing cause inconsistent wall thickness of finished bins, resulting in weak impact resistance
3.Unreasonable split structure increases the difficulty of demoulding and assembly during production
4.Ordinary thin steel moulds are prone to wear and tear, requiring frequent replacement in high-volume production lines
Solution
1.Adopt high-quality thick carbon steel plates, processed by CNC precision cutting and full penetration welding for enhanced structural stability
2.Optimize the mould cavity design to ensure uniform wall thickness of finished HDPE bins, improving impact and load resistance
3.Scientific split structure with flange positioning holes and reserved lifting points for easy disassembly, installation and demoulding
4.Professional anti-rust and anti-corrosion surface treatment to extend the mould's service life under long-term production conditions
Specifications
Raw Material: Heavy Duty Mild Carbon Steel
Processing Technology: CNC Cutting + Full Welding + Anti-rust Coating
Customization: Mould size and cavity capacity can be customized according to customer’s drawings (e.g. 60L/120L/240L/360L standard bin sizes)
Structure: Split mould with outer fixed support frame (standard configuration)
Application
Used for rotomolding production of outdoor HDPE garbage bins, municipal waste containers, commercial trash cans, industrial waste bins, and public sanitation plastic bins in parks, streets, communities and industrial zones.
How To Choose
Choose this heavy-duty steel rotomould when:
You need mass continuous production of outdoor HDPE garbage bins
You require a mould with high structural strength and long service life for long-term operation
Your products are for public/commercial use and demand high durability
Choose aluminum mould when:
Only small-batch trial production is needed
The finished bin requires ultra-high surface finish or complex details
FAQ
Q1: Can this mould be customized for different bin sizes?
A: Yes, we provide full OEM & ODM customization based on customer drawings or samples, supporting standard sizes from 60L to 1100L.
Q2: How long is the service life of this heavy-duty steel mould?
A: With standard maintenance, it can support tens of thousands of rotomolding cycles, far longer than ordinary steel or aluminum moulds.
Q3: Is the outer support frame included?
A: Yes, the fixed outer support frame is matched with the mould as standard, as shown in the product photos.
Q4: Is anti-rust treatment provided?
A: All finished steel moulds are treated with professional anti-rust coating before delivery to prevent rust during transportation and storage.
