Product Description

OEM ODM Agricultural Seeding Hopper Rotational Steel Mould

Custom carbon steel rotomold manufactured by SUNMORE factory, specially designed for producing integral PE plastic agricultural seeding hoppers via rotational molding technology.

Product Advantages

Carbon steel hopper mould offers high structural strength, low production cost, excellent wear resistance, and is ideal for mass continuous production of farm seeder plastic hoppers.

Traditional Production Challenges

Poor mould processing accuracy leads to inconsistent wall thickness
Inferior welding causes mould deformation after repeated high-temperature processing
Unreasonable split structure increases demoulding difficulty
Thin steel material leads to premature damage and scrap

Our Solutions

Premium carbon steel sheet with CNC precise cutting and full penetration welding
Optimized inner cavity structure for uniform wall thickness
Fixed flange holes and integrated lifting frame for easy disassembly and demoulding
Complete anti-rust surface treatment for enhanced corrosion and abrasion resistance

Specifications

Customization	All sizes customized per customer design drawings or sample requirements
Raw Material	Mild carbon steel
Processing Technology	CNC cutting + full welding + surface anti-rust treatment with fixed support bracket

Applications

Used for rotational molding production of agricultural seeder feeding hoppers, farm fertilizing hoppers, machinery feeding funnels, gardening plastic storage hoppers, and other agricultural plastic accessories.

Selection Guide

Choose Carbon Steel Mould When: Mass continuous production of PE seeding hoppers, cost-effective customization for long-term batch manufacturing.

We got this agricultural seeding hopper mold via OEM customization. The steel mold is solid with fine inner finish. Produced plastic hoppers have even wall thickness and no deformation, ideal for farm seeding equipment production. The factory finished mold modification per our drawing quickly.

Ordered three sets of seeding hopper roto molds for our agricultural factory. High hardness steel material ensures long service life under continuous mass production. Finished plastic hoppers are wear-resistant and fit farm machinery perfectly. Remote technical support is available whenever needed.
