Plastic Rotational Mould Manufacturers | Custom Roto Moulding Tooling

Top-Tier Plastic Rotational Mould Manufacturers

As premier plastic rotational mould manufacturers, Unique Mould provides expert solutions in roto moulding tooling. We design and fabricate high-precision, durable moulds for a vast range of applications, including water tanks, industrial containers, and custom plastic products. Our focus is to deliver moulds that ensure consistent product quality and long service life.

Precision Engineering for Rotational Moulds

The process of creating a rotational mould involves casting or CNC machining from high-grade materials like steel or aluminium. We use advanced 3D modelling to design complex mould geometries, ensuring uniform wall thickness in the final product. Our fabrication process includes precision welding and surface finishing for seamless, high-quality part production and optimal performance.

FAQs – Plastic Rotational Mould Manufacturers

1. What materials are used to make rotational moulds?

Rotational moulds are typically made from fabricated sheet steel, cast aluminium, or CNC-machined aluminium, depending on the part's complexity and required finish.

2. How long does a rotational mould last?

A well-maintained steel rotational mould can last for tens of thousands of cycles. Aluminium moulds also offer excellent durability, especially for complex shapes.

3. Can you manufacture moulds for very large products?

Yes, as experienced rotational mould manufacturers, we specialize in fabricating large-scale moulds for items like 10,000-litre water tanks and large industrial containers.

4. What is the difference between an injection mould and a rotational mould?

Rotational moulds are typically used for large, hollow parts with uniform wall thickness, while injection moulds are for solid, often complex parts, under high pressure.

5. Do you provide custom design support?

Yes, we offer complete design and engineering support, from 3D modelling and prototyping to the final fabrication of your custom rotational mould.
