Rotational Molding Capabilities

Precision-formed plastic solutions for large-format, lightweight, and cost-efficient components.

At Qualix, we engineer rotationally molded parts for demanding applications ranging from industrial tanks and containers to outdoor equipment housings and heavy-duty enclosures, supported by in-house mold development and process control focused on long-term performance.

Mold Development: Precision Tools, Built to Last

We design and manufacture thermoforming molds in-house, enabling rapid iteration, tight dimensional control, and cost-effective tooling strategies tailored to your production volume.

Mold Materials & Applications

• Aluminum Molds
  Industry standard for rotomolding; excellent thermal balance, lighter weight, and cost-effective for medium to high volumes

• Steel Molds
  Used for large parts, aggressive textures, or applications requiring extended mold life

• Fabricated Aluminum Molds
  Ideal for large tanks or enclosures where welded construction is required

Tool Design Optimized for Rotational Processes

Our engineers focus on details that directly affect part performance:

• Uniform material distribution through controlled mold geometry

• Corner and rib design to avoid thin spots

• Venting strategies to prevent voids and surface defects

• Parting line optimization for clean separation and consistent appearance

Tooling Precision & Validation

• Mold dimensional accuracy: ±0.5 mm (size dependent)

• Surface finishes: Smooth, textured, or anti-slip patterns

• First-article trial with full dimensional and functional verification

Process Capabilities

• Even wall thickness across complex geometries

• No high-pressure forming—minimal internal stress

• Capability to mold fully enclosed hollow parts with no seams

• Mold-in features such as ribs, bosses, and inserts

Part Size & Production Range

• Small enclosures and containers

• Medium to large tanks (up to industrial-scale volumes)

• Thick-wall structural components for outdoor or industrial use

Material Expertise: Engineered for Harsh Environments

Rotational Molding Processes: Built for Thick Walls and Complex Shapes

Performance Characteristics

• Wall thickness range: 3 mm – 20+ mm

• Excellent impact resistance and crack resistance

• Superior performance in low-temperature environments

• High resistance to environmental stress cracking
