Quality Rotational Molding Services

Quality Rotational Molding Services

Stern Companies total commitment to our customers goals has included the performance of quality rotational molding services in a timely and cost-efficient manner.

Rotational molding is a low-pressure process and the strength required from the molds is minimal.  This results in its ability to produce large or complex parts on short notice, using inexpensive molds.  Due to the low tooling cost, rotational molding is ideally suited for producing prototypes and small or large quantities of production parts.  Rotational molding tends to produce an increasing wall thickness on outside corners of parts, which gives the process a distinct advantage.  We have the technical ability and technology needed to execute intricate contours, undercuts, molded-in inserts and double walls. 

Our product expertise applies to everything from specialty tanks to storage containers as well as kayaks, agricultural products and boat consoles.

Our Rotational Molding Facility equipment includes:

  • Ferry RotoSpeed 370 - 4 arm turret
  • Ferry RotoSpeed 280 - 4 arm turret
  • Ferry RotoSpeed - 3000 - 2 arm shuttle
