R&D

1. Drawing Review: The technical drawings and specifications are thoroughly reviewed to ensure they meet design requirements, functional needs, and manufacturing feasibility.
2. Mould Structure Design: Custom molds are designed to accommodate the rotational molding process, considering factors like material flow, wall thickness distribution, and cooling efficiency.
3. Prepare Materials: High-density polyethylene (HDPE) or other thermoplastic resins are selected and prepared, often in powdered form, for optimal melting and molding.
4. CNC Shaping: Molds are precision-machined using Computer Numerical Control (CNC) technology to achieve exact dimensions and surface finishes.
5.Surface Treatment: The mold surfaces undergo treatments (e.g., coating, cleaning) to enhance material release and prevent adhesion during the molding cycle.
6. Polishing Treatment: Molds are polished to ensure smooth interiors, minimizing imperfections in the final product.。
7. Assembling: Molds are assembled, and any inserts or fixtures (e.g., hinges, handles) are integrated.
8. Finished Product Packaging: Completed rotational-molded parts are inspected, cleaned, and packaged according to client requirements.
9. Delivery: The packaged products are shipped to customers or distribution centers.

CNC Machines in Rotational Molding

CNC (Computer Numerical Control) machines are critical tools in the rotational molding industry, primarily used for precision manufacturing of molds.
Function:
1.Create complex, high-accuracy mold cavities from materials like aluminum, steel, or composite resins.
2.Ensure smooth surfaces and dimensional consistency for uniform plastic distribution during the molding process.

Working Principle
1.Heating Phase: The mold, loaded with plastic powder, rotates in an oven (200–350°C) to melt the material uniformly.
2.Cooling Phase: The mold is transferred to a cooling station (air/water-cooled) to solidify the product.
3.Demolding: The finished part is removed, and the cycle repeats.
