Custom Rotomolding Services

Rotomolding, or rotational molding, is a manufacturing process used to create durable, seamless coatings and components with uniform wall thickness. This method is ideal for producing high-performance linings and parts that require strength, consistency, and resistance to harsh environments.

How Rotomolding Works

In the rotomolding process, a mold is filled with polymer material and slowly rotated while being heated. As the material melts, it evenly coats the interior of the mold, forming a uniform, seamless structure.

This process allows for:

Consistent wall thickness
Seamless construction
Strong structural integrity
Design flexibility

Benefits of Rotomolding

Rotomolding delivers durability advantages that make it well suited to industrial parts and linings operating in demanding, corrosive, or high-wear environments:

Excellent durability and impact resistance
High chemical and corrosion resistance
Uniform thickness without weak points
Ability to produce complex shapes
Long service life with minimal maintenance

Materials Used

We work with a range of high-performance materials depending on the application, including:

Polyethylene
Nylon
Fluoropolymers
Other engineered thermoplastics

Applications

Rotomolding is used across a variety of industries where durability and resistance are critical, including:

Rotomolding vs. Other Manufacturing Methods

Rotomolding differs from injection molding and machined fabrication in cost and tooling. Because it uses a hollow mold and rotational heating rather than high-pressure injection, tooling costs are typically lower, making it well suited to large or hollow parts and custom, low-to-mid-volume production. The trade-off is a longer cycle time per part than injection molding, which is more economical at high volumes with simpler geometries.

For applications where the goal is a corrosion-resistant lining inside an existing pipe or fitting rather than a standalone molded part, rotolining may be the better fit. Our team can help determine which process matches a given project’s geometry and end use.

Why Choose Us

Our experience in rotational molding ensures precision and consistency across every project. We tailor each solution to meet the specific performance and environmental requirements of our clients.

What is rotomolding and how is it different from rotolining?

Rotomolding, or rotational molding, is a manufacturing process that forms a seamless part or lining by rotating a heated mold filled with polymer material until it evenly coats the mold’s interior. It’s closely related to rotolining, which applies the same rotational technique to line the inside of an existing pipe or fitting rather than molding a standalone part.

What materials can be rotomolded?

We work with a range of high-performance materials, including polyethylene, nylon, fluoropolymers, and other engineered thermoplastics, selected based on the chemical exposure, temperature, and mechanical demands of the application.

What are the advantages of rotomolding over other manufacturing methods?

Rotomolding produces seamless, uniform-thickness parts without weak points, and its lower tooling costs make it well suited to large, hollow, or custom components that would be expensive to injection mold.

Which industries use rotomolded parts and linings?

Rotomolding is common in oil and gas, chemical processing, general industrial equipment, and water and wastewater systems, wherever durable, corrosion-resistant components are required.

How long does the rotomolding process take?

Timelines depend on part size, material, and mold availability, along with current shop volume. Contact us with your project specs for a turnaround estimate along with your quote.

Do you accommodate custom or one-off parts?

Yes. The “custom” in Custom Rotomolding Services means we work with clients to accommodate unique shapes, sizes, and one-off or low-volume parts. Contact us to discuss your design and specifications.
