What is rotational molding？

Roll molding is a hollow forming method for thermoplastic materials, which involves uniformly coating, melting, and adhering the plastic material to the surface of the mold cavity through the rotation and heating of the mold, and then cooling and shaping it. Common products include containers (such as sinks and storage tanks), automotive parts (such as fittings and interiors), sports equipment (such as water balloons and floats), toys, handicrafts, etc. They have the characteristics of low cost, flexible design, and excellent quality.

Rotational molding recycling has significant multiple benefits: it not only effectively saves petroleum resources and reduces dependence on primary resources, but also avoids waste rotational molding from becoming a source of environmental pollution and protects the natural environment; At the same time, recycling waste rotational molding can reduce production costs and create economic benefits.

Recycling and reuse process

Waste rotational molding is strictly cleaned to remove pollutants; Subsequently, it is cut into suitable fragments by shredding equipment and then processed into small particles by crushing machinery; Then the particles enter the high-precision grinding equipment to form a fine powder; Finally, the powder is melted, extruded, cooled, and cut during the granulation process, and converted into high-quality recycled particles, achieving efficient reuse of waste rotational molding throughout the entire process.

Characteristics of Recycling Machinery

Fully automated: unmanned or few person operation, saving labor costs.

Dust free environment: Avoid dust interference in the workshop and maintain a clean working environment.

High yield and efficiency: processing capacity of 2000-3000kg/h, improving production efficiency.

Intelligent control: HMI touch screen system, one click start, fault alarm and diagnosis, supports PC monitoring.

Separation design: Separation of feed, powder collection, and mill system, optimizing equipment layout.

Remote silo: The vacuum system automatically feeds, grinds, and collects materials, and the silo can be placed remotely for easy management.
