Rotational molding plastisol is a unique process that allows for hollow parts. The rotational molding process involves 4 stages:  Loading the plastiol and sealing the mold, rotating and fusing the plastisol parts, cooling the plastisol part, and demolding/unloading the plastisol part.  The de-mold and loading is typically performed in the same stage.  In the rotating and fusing stage, the mold is rotated in two planes, perpendicular to each other, while heated.  The plastisol first gels onto the mold surface and builds an even coat, developing a hollow molded part. Additional heat fuses the plastisol.

For uniform wall thickness, flow properties and the gelation cycle is very critical. Lakeside Polymer Service understands rotational molding and will custom formulate plastisols for each specific rotational molding process, as well as any other specific product specifications.

Lakeside Polymer Services provides the following plastisols for rotational molding:

  • Uniform deposition of plastisol for even wall distribution
  • Fast gel and fast fusing
  • Soft to rigid hardness
  • Excellent mold release
  • Superior heat stability for processing with other polymers
  • Nearly unlimited color selection.
