Redline Plastics Rotational Molding:

Custom Rotational Molding for Complex Plastic Parts

Redline Plastics provides custom rotational molding backed by in-house engineering, manufacturing, finishing and fulfillment capabilities. From early product development through production and shipping, our team helps manufacturers turn demanding plastic-part requirements into repeatable, production-ready solutions.

With manufacturing facilities in Manitowoc, Wisconsin and Hartwell, Georgia, Redline supports customers across the United States with the capacity, technical expertise and secondary services needed to manage more of the manufacturing process through a single partner.

Rotational Molding from Product Design Through Production

A successful rotomolded plastic part starts well before resin enters the mold.

Redline’s staff of plastics, mechanical and manufacturing engineers can evaluate your product design, material requirements and manufacturing objectives to help determine how effectively the part can be produced through rotational molding. That support is especially valuable when transitioning a new design into production or evaluating how an existing component can be manufactured more efficiently.

Once production begins, Redline can continue beyond the molding operation with CNC trimming, assembly, product testing, packaging, warehousing and drop shipping.

Instead of coordinating multiple vendors for molding and secondary operations, customers can consolidate more of the production process with one manufacturing team.

From concept development to the final product, we ensure precision, durability, and a seamless finish to deliver WOW (a key part of our award winning team culture).

Applications of Rotational Molding

The versatility of rotational molding makes it ideal for a wide array of industries and products:

– Tanks and Containers: Storage tanks, bins, and containers for industrial, agricultural, and commercial use.

– Lawn & Agriculture Components: Air ducts, fuel tanks, and interior trim pieces.

– Recreational Equipment: Playground equipment, kayaks, and marine buoys.

– Customized Products: Complex and intricate designs, including furniture, medical equipment, and specialized enclosures.

Materials Used in Redline Rotomolding:

• Cross-Linked PE (Cross-Linked Polyethylene) XLPE : Used for high impact resistance and strength, such as in diesel fuel tanks. Redline Plastics can offer a wide variety of in-mold decoration methods for this material, enhancing its aesthetic appeal and functionality.
• LLDPE (Linear Low-Density Polyethylene): Known for its flexibility and strength, making it ideal for products that require durability. Redline Plastics can apply in-mold decoration techniques to create intricate designs and labels that are integral to the product.
• HDPE (High-Density Polyethylene): Valued for its strength and resistance to impact and chemicals, suitable for items like containers and industrial parts. With in-mold decoration methods, Redline Plastics can incorporate detailed graphics and branding directly into HDPE products.
• Nylon: Used for items like hydraulic tanks due to its excellent mechanical properties and resistance to wear. Redline Plastics’ in-mold decoration capabilities can add custom designs and identifiers, enhancing the utility and appearance of nylon-based products.
• PVC (Polyvinyl Chloride): A versatile material used in a variety of applications due to its durability and resistance to corrosion and chemicals. Redline Plastics can integrate in-mold decoration techniques to PVC items, ensuring long-lasting and visually appealing results.

Is Rotational Molding Right for Your Part?

Plastic rotational molding is particularly well suited to applications where part size, durability, design flexibility or tooling economics make other manufacturing methods less attractive.

Manufacturers commonly choose rotational molding for:

• Large plastic parts: Redline can rotationally mold parts up to 181 inches.
• Complex shapes: Rotomolding provides substantial design flexibility for products that would be difficult to manufacture using many other processes.
• Durable components: The process can produce strong, stress-free parts for demanding commercial and industrial applications.
• Hollow products: Tanks, containers, housings and similar enclosed or hollow components are common rotational molding applications.
• Lower tooling investment: Tooling costs can be more economical than processes such as injection molding, particularly for large components.
• Product customization: Designs, colors and product configurations can be adapted to specific customer requirements.

If you are comparing rotational molding with another plastic manufacturing process, Redline’s engineering team can review the application and help determine whether rotomolding is a practical fit before you commit to production.
