Product Description

Professional Rotational Molding Tool for Agricultural Applications

SUNMORE ROTO Custom Rotomolding Iron Agricultural Seeding Hopper Mould is a professional rotational molding tool independently designed and manufactured by SUNMORE ROTO factory. This agricultural seeding hopper mould adopts split steel plate welded structure with heavy-duty external support frame. It is specially matched with bi-axial shuttle rotomolding machines for mass production of integrated seamless PE plastic seeding hoppers, agricultural seed storage boxes and farming feeding containers.

We provide full-size customized service according to customers' requirements on hopper volume, upper outline, tapered bottom shape and discharge outlet structure. The mould inner cavity can be finely machined and polished as required to ensure smooth surface of finished plastic hoppers. Reinforced steel support frames are welded outside the mould to reduce deformation during long-term high-temperature cyclic rotational molding.

Key Features & Benefits

Split Combined Steel Welded Structure: Thick steel plate integrated welding with locking fixtures for easy opening and demoulding, improving continuous production efficiency
High Rigidity Heavy-Duty Design: External reinforced support frame evenly disperses thermal stress and mechanical load under repeated high-temperature rotation, effectively avoiding cavity bending deformation
Optional Fine Polished Inner Cavity: Inner mould cavity surface can be finely processed and polished upon request for smooth inner walls that reduce seed adhesion
Fully Customizable Hopper Specifications: Support customization of hopper capacity, top outline, tapered bottom angle, discharge outlet position and shape
Stable Heat Transfer Performance: Steel material provides stable heat transfer during rotational molding, helping control wall thickness and improve finished product consistency
Universal Installation Base: Standard connecting bases compatible with mainstream bi-axial shuttle rotomolding equipment

We ordered the 10T rotomolding mold for large water tanks supporting municipal engineering water supply projects. The aluminum mold has uniform thermal conductivity, finished large water tanks have even wall thickness with no concave or bulging. After three months of continuous mass production, mold stability is outstanding, and we are preparing to purchase three more sets for new urban water supply projects.

We bought multiple sets of steel fuel tank molds for our industrial tank production line. Solid steel structure improves mould service life greatly, finished plastic fuel tanks feature even wall thickness and excellent tightness without leakage. The supplier completes OEM modification as per our drawings efficiently.
