Rotational Moulding
Large-scale polymer parts with strength and precision
Rotational moulding is a versatile polymer processing method used to produce large, hollow, and impact-resistant parts with uniform wall thickness. At Matrix Composites & Engineering, we use this low-pressure, high-precision technology to manufacture structural polymer components for demanding applications in defence, energy, and infrastructure.
Using our in-house Reinhardt rotational moulding machine, we produce complex, high-integrity shapes with consistent quality and minimal waste. This capability enables us to manufacture durable products at scale – including barrier systems for FortaWall™, custom buoyancy modules, and subsea housings.
Rotational moulding produces seamless, impact-resistant polymer parts with uniform wall thickness — ideal for large, durable components in harsh operating environments.
KEY BENEFITS
Uniform Wall Thickness
Controlled heating and rotation ensure even material distribution for consistent mechanical strength.
High Impact Resistance
Produces strong, shock-absorbing parts ideal for demanding and heavy-duty environments.
Efficient Large-part Production
Forms complex, hollow geometries in a single cycle — ideal for oversized or structural components.
Corrosion Resistant Materials
Uses polymers that withstand water, chemicals, and degradation for long service life.
Material Versatility
Compatible with a wide range of thermoplastics, including UV- and chemical-resistant grades.
Cost-effective Manufacturing
Low pressure process and simple tooling making it ideal for small to medium production runs.
APPLICATIONS
Rotational moulding is ideal for manufacturing durable, large-format components with consistent strength and impact resistance, including:
- Modular wall barriers and safety structures for civil and infrastructure projects.
- Buoyancy modules and marine floats engineered for durability and long-term use.
- Protective housings and covers for subsea and harsh-environment installations.
- Encapsulation of electronics and sensors in chemically resistant polymer shells.
- Tanks, canisters, and covers used in mining and processing systems.
- Corrosion-resistant containers for chemical, water and waste treatment applications.
- Defence-grade polymer components designed for strength, reliability and field durability.
- Transport and containment products with complex shapes or internal volumes.
